SUNTES Type C PSW-1331, PSW-1535 and PSW-1735 Load Testers

SUNTES Type C load testers are low-speed, high-torque dynamometers for applying a controlled mechanical load to rotating equipment. The design uses a water-cooled disc mounted on the input shaft, clamped by pneumatic or hydraulic disc brakes. A load cell detects the resulting reaction force, which is converted into torque for measurement and test control.

Load generation and test capability

The mechanical disc-brake arrangement supports load testing at low rotational speeds and high torque. The test load can be set to suit the required duty within the selected machine's operating limits. Fluid-coupling stall tests are among the stated capabilities. Define the required torque and speed conditions, test duration and load sequence when selecting a system so that the absorption and cooling requirements can be reviewed together.

Applications

Typical uses include noise and efficiency tests on speed reducers, travel-drive tests for agricultural and construction machinery, destructive testing of universal shafts, efficiency tests for fluid couplings and a variety of endurance tests. The test rig, coupling arrangement and measurement system must be specified for the intended specimen and test method. A suitable load tester supplies the resisting load; the surrounding rig and instrumentation determine how the particular test is performed.

Model-specific ratings

Type C includes PSW-1331, PSW-1535 and PSW-1735. Maximum absorbed powers are 67.5, 90 and 180 kW, with maximum torques of 5.7, 39.6 and 66 kN·m respectively. Their listed maximum speeds are 1,500, 1,000 and 600 min⁻¹. Cooling-water flows are 45, 60 and 120 L/min. PSW-1735 provides the highest listed absorbed power and torque in this Type C group; selection must still account for the complete power-speed duty and required cooling conditions.

Control cabinet and load regulation

A standard control cabinet is available for the load tester. An optional load controller compensates for variations in load torque to maintain a stable controlled load. Special measurement and control panels can also be designed to match the required measurement and control functions. Identify the required signals, control behaviour and measurement functions when specifying the test system; do not assume that optional closed-loop control or a custom panel is included in a basic machine.

Cooling, pressure and operating envelope

All listed pneumatic models have a maximum air-pressure setting of 0.7 MPa. A hydraulic-servo, hydraulically controlled version is also available for specification review. The maximum absorbed power, maximum torque and maximum speed are separate limits and should not be treated as simultaneously achievable operating points. Check the actual torque-speed test schedule, thermal duty and cooling-water supply against the selected machine's approved operating envelope.

Installation and ordering

Provide the complete PSW model, test torque and speed range, duty cycle, specimen connection, required control functions and available utilities. Use the dimension table with the corresponding drawing, including shaft diameters, shaft extension and mounting-hole callouts. Type B and Type C include both capital L and lower-case ℓ references; preserve this distinction. Confirm the current drawing, utility conditions and application suitability before machining adapters or approving the rig layout.

SUNTES SE Torque Releasers: TE-1411 to TE-3833 Ball-Clutch Safety Elements

SUNTES SE-Series torque releasers use a ball-clutch, release-type safety-element cartridge arrangement. They automatically release when an overload occurs in the drive shaft system and are intended for equipment such as presses, kneading machines and plastic-moulding machinery. The coupling-type dimensional range listed here uses TE model codes from TE-1411 through TE-3833.

Torque transmission and overload release

During normal operation, spring force presses a ball into its mating hole and torque is transmitted through that contact. When torque exceeds the setting, the ball moves out against spring force. The retaining mechanism then holds the assembly in a free-rotation state. The plunger moves outward during release, and this projecting movement can be used to actuate a sensor for overload detection.

Free-rotation retention and reset

As the main ball leaves its hole, the plunger is pushed back. Smaller balls around the plunger move into the angle-race arrangement against spring force, removing the plunger thrust that would otherwise press the main ball into engagement. To reset, first align the fixed-position marks and then push the plunger inward. This is a deliberate reset operation; the overload cause and required machine restart checks must be addressed before returning the equipment to service.

Torque adjustment

Turning the adjuster inside the element to the right increases the transmitted torque setting. This adjustment is performed with the element removed from the flange. The arrangement helps prevent unintended adjustment by people who should not alter the setting. Specify the required release torque and have the correct safety element and adjustment procedure confirmed for the assembly rather than treating the maximum table value as a universal operating setting.

TE models and safety elements

The specification table matches each TE assembly to a maximum torque setting and a safety-element designation. TE-1411 and TE-1611 use #10 elements; TE-2315 through TE-2721 use #20; TE-3322 through TE-3833 use #30. Maximum settings range from 7,000 N·m for TE-1411 to 376,600 N·m for TE-3833. The dimensional drawing is specifically for the coupling type, and its lettered dimensions must be checked against the complete model row.

Selection and order preparation

Provide the TE model, required setting, safety-element designation, operating duty, shaft and coupling interfaces, and the planned overload sensor. Check access for alignment, plunger reset and element removal. Special specifications are available for review. Confirm the actual operating limits, element arrangement and current assembly drawing before final selection; dimensions alone do not establish a permissible speed or complete application rating.

Dimensions and specifications

Use the lettered dimensions with the corresponding drawing. Torque is stated in N·m, speed in min⁻¹, and mass in kg where indicated. Fit tolerances, drawing symbols, grouped rows and blank entries are retained. A blank entry is not zero.

SUNTES TV30DW to TV160DW Cassette Shear-Pin Torque Releasers

SUNTES TV-DW torque releasers use a cassette shear-pin configuration to automatically release the drive when an overload occurs in the shaft system. The range includes TV30DW, TV40DW, TV60DW, TV70DW, TV80DW, TV95DW, TV110DW, TV120DW and TV160DW. Typical applications include presses, kneading machines and plastic-moulding machinery.

Shear-pin overload protection

The TV family is identified as a shear-pin type. Its overload-release arrangement must be selected for the intended machine duty and torque level. Automatic release describes the response to an overload and must not be confused with the automatic-reset behaviour of the TX family. Confirm the cassette-pin specification and the required restoration procedure for the exact TV model before commissioning or servicing the drive.

Speed and torque ratings

Every model in the listed specification table has a maximum speed of 100 min⁻¹. Maximum torque increases from 500 N·m for TV30DW to 35,000 N·m for TV160DW. Intermediate values are 1,000, 1,500, 2,000, 4,000, 8,000, 15,000 and 20,000 N·m for TV40DW through TV120DW respectively. These maximum figures define model-specific limits; the required release condition and pin arrangement must be confirmed for the application.

Dimensions and mass

The drawing and table identify D0 through D4, L1 through L4, the pitch-circle diameter and the N-d mounting callout. These values must be checked together with the shaft and mating component geometry. Product mass ranges from 4.5 kg for TV30DW to 186 kg for TV160DW, with separate values for each intermediate model. Include the selected assembly in support, handling and maintenance-access planning. Do not infer interchangeability from a shared bolt size or a similar shaft dimension.

Application and order review

Provide the complete TV-DW model, operating speed, normal and overload torque requirements, machine type, shaft dimensions and mounting arrangement. Include the load cycle and any startup torque peaks that affect the intended protection setting. Use the correct cassette pin and current dimensional drawing for the chosen unit. After a release, investigate the overload before restoring service and follow the applicable maintenance procedure. Confirm the application-specific setting and current specifications before manufacturing mating parts or ordering replacement components.

SUNTES TY-A, TY-D and TY-AR Torque Releasers: Construction and Manual Reset

The SUNTES TY torque-releaser family disconnects torque transmission when the drive load exceeds its selected setting. The A, D and AR configurations share the same basic clutch mechanism. The A-type assembly is used here to explain how the normal transmitting state, overload release and reset sequence differ.

Normal torque transmission

Steel balls held by the hub boss are pressed into flange pockets by spring force. Torque passes from the hub boss through the balls to the flange. The bearing, case, segments, taper ring and slide ring form part of the assembly that controls its released and reset states.

Overload release and detection

When an overload pushes the balls out of the flange pockets, torque transmission is interrupted. The segments move along the hub-boss ramps against spring force and spread the case and taper ring. At the top of the hub projections, the force pressing the balls into the flange pockets is removed, allowing the flange to rotate freely on its bearing. The case moves axially toward the adjust ring, providing displacement that can be detected by a limit switch or proximity switch.

Manual reset after clearing the overload

First remove the cause of overload. Rotate either the input or output until the alignment marks on the hub boss and flange coincide. Press the case toward the flange to reset the mechanism. The released free-rotation state and deliberate reset action are essential distinctions from an automatic-reset unit. Provide access to the alignment marks and the reset mechanism in the machine layout.

Configuration and control review

Select the physical configuration to match the mounting interface and driven equipment, then use its own specification tables for the release-torque range, spring arrangement, speed and shaft dimensions. The operating diagrams explain the mechanism rather than assigning a universal rating to every size. For ordering or service discussions, identify the full model, setting, shaft arrangement, overload detector and required restart sequence. Use the component-reference drawing to identify parts accurately and confirm the current operating instructions for the chosen assembly.

Construction and component reference numbers

Confirm the latest dimensional drawing and specifications for the selected configuration before manufacture or installation.

SUNTES TY30-A, TY30-D, TY40-A, TY40-D, TY50-A, TY50-D, TY65-A and TY85-A Roller-Chain Sprockets

SUNTES roller-chain sprockets for TY-A and TY-D torque releasers must be selected by the complete releaser configuration, chain size and required tooth count. The compatibility matrix below lists the tooth-count ranges that can be fitted for each combination. The machining table then defines the mating interface used to attach the sprocket to the releaser.

Reading the compatibility matrix

Column headings beginning with # identify roller-chain sizes, while T denotes the number of teeth. A range such as 27–46T describes the listed tooth-count interval for that chain and releaser combination. Blank cells mean that no compatible range is listed; they do not indicate zero teeth or unrestricted compatibility. Select the exact model row and chain-size column together before checking the required tooth count.

Configuration-specific machining

The second table must be used with the dimensional drawing. Lettered dimensions, bolt-circle references, hole callouts, fit classes and surface-finish symbols identify different machining requirements. A D-type flange and an A-type interface can require different sprocket geometry even when the nominal releaser size is the same. Preserve the model prefix and suffix throughout drawing preparation and purchasing. The tolerance values shown with H7 fits must be included when checking the locating interface.

Drive integration

Tooth count forms part of the chain-drive ratio and affects the sprocket geometry. Verify the intended chain specification, mating sprocket, available installation space and alignment as part of the drive design. The compatibility table describes available mounting combinations; it does not by itself establish a chain load rating, an allowable machine speed or a torque-release setting. Those requirements must be checked separately for the complete drive.

Ordering and drawing review

Provide the TY releaser type and size, chain number, tooth count and the required mating-interface drawing. State whether a sprocket or a completed releaser assembly is required. Before manufacture, check the full machining row, including locating fits, bolt pattern and finish callouts, against the current drawing. Values marked with ≤ mean the stated maximum. Drawing symbols are retained so that their meaning can be checked in context; they should not be converted into assumed numerical roughness values.

SUNTES TY30, TY40, TY50, TY65 and TY85 ON/OFF Shifters

SUNTES ON/OFF shifters are associated with TY-Series torque releasers. The listed dimensional range covers TY30, TY40, TY50, TY65 and TY85. The shifter arrangement and air-cylinder specification must be matched to the actual TY assembly and the available installation space.

Role in the TY installation

TY torque releasers use a manual-reset clutch mechanism. After an overload, the cause must be removed and the correct alignment and reset sequence followed. The shifter is a separate accessory arrangement; its dimensional data do not change the release-torque rating of the torque releaser. Review the required ON/OFF and reset operation for the complete machine before choosing the actuator and control sequence.

Two complementary dimensional tables

The first table gives dimensions A through H and L through P. The second continues with Q through W, diameters X, Y and D0, and the air-cylinder specification. Both rows for the same TY size are needed to define the arrangement. Do not combine one size's main dimensions with another size's cylinder data. Check every letter against the corresponding drawing, including the support and mounting envelope.

Cylinder specification and layout

The air-cylinder entries are 63 × 30ST for TY30, 80 × 30ST for TY40, 100 × 35ST for TY50, 125 × 45ST for TY65 and 160 × 50ST for TY85. Retain these complete callouts when discussing the arrangement. The table does not provide an operating-air pressure, switching time or control-circuit specification. Confirm those requirements for the selected cylinder and machine installation rather than assuming that dimensions alone establish actuator performance.

Selection and ordering

Provide the full TY releaser model and size, the desired shifter arrangement, mounting constraints and the proposed operating sequence. Review access to the reset mechanism, alignment marks and overload-detection components. Check the current accessory drawing together with the releaser drawing before manufacturing brackets or releasing a purchase order. The complete machine control must determine when shifting and restarting are permitted; use the approved operating procedure for the selected assembly.

SUNTES TY30AR, TY40AR, TY50AR, TY65AR and TY85AR Coupling Torque Releasers. These units interrupt power transmission when the torque in the drive system exceeds the selected setting. Choosing the correct size, spring variant and mechanical interface helps limit the effects of sudden overloads on the connected machinery. The full model suffix identifies the setting configuration and must be retained in an order.

Configuration and installation interface

The AR configuration integrates a coupling with the manual-reset releaser. Separate shaft-interface tables cover the releaser and coupling. Provide the two required shaft diameters and check the overall length, coupling envelope and reset access before approving the installation.

Manual-reset operating sequence

Spring-loaded steel balls transmit torque between the hub boss and flange during normal operation. An overload forces the balls out of the flange pockets. Segments move along the hub-boss ramps and spread the case and taper ring, removing the force that holds the balls in their pockets. The flange can then rotate freely on its bearing. Axial movement of the case toward the adjust ring can be used for limit-switch or proximity-switch overload detection. After removing the overload cause, rotate one side until the hub-boss and flange alignment marks coincide, then press the case toward the flange to reset.

Torque setting and characteristic curves

The L, H and G variants have distinct torque-setting ranges and spring combinations. The specification table gives spring color and quantity, maximum speed, moment of inertia and product mass. Torque can be varied in proportion to the number of springs, with a stated minimum of three springs. Use the characteristic curve for the appropriate size when reviewing a setting. Changing spring count requires the correct configuration and adjustment procedure; the top of a torque range is not a universal recommended operating setting.

Selection and ordering

Specify the exact type, size, L/H/G variant, required release torque, actual shaft speed and shaft-bore arrangement. Include normal running torque, startup conditions, the driven-machine duty and the mounting details. Check overload-detection travel and allow access for adjustment and reset. Where a value spans several rows, it applies to the associated grouped variants. Fit tolerances, pilot bores and screw callouts are retained in the data below. Confirm the current drawing and application suitability before machining mating components.
