General technical description
Types and sizes
The flexible element is designed to combine high torque transmission capacity with high speed capability. Its torsional stiffness is easily adaptable to the requirements by selecting just the right rubber quality. Bearings or integrated joints support the loads arising from the connection between the drive end and the output end. Cardan shafts, constant velocity (CV) shafts and compact shafts are available as connections which also compensate for misalignments. Adaptive designs are based on the standard DIN or SAE flange connection dimensions, the CV shaft joints and the torque measuring fl anges. The couplings cover a torque range from approx. 100 Nm at 10.000 rpm up to 70.000 Nm at 1.800 rpm.
Test benches are used for a wide variety of applications in power transmission engineering to determine properties of test objects in research, development, manufacturing and quality assurance. The drive train components which are predominantly tested on test benches include, but are not limited to, engines, gearboxes, transmission elements and consumables. Given the multitude of different testing tasks, the specific requirements for couplings on test benches are manifold. The TOK coupling system can be used in almost all test bench applications, and on engine test benches in particular. The broad range of flexible coupling elements, adaptive designs and connection shafts provides standard solutions for a wide variety of different tasks, and these can be complemented by specific customised designs on request.
Essential properties and advantages of the highly fl exible TOK coupling systems:
• Elements available in different torsional stiffnesses
• Suited for highest speeds
• Adaptation to DIN or SAE fl anges or according to specification
• Self-centering, backlash-free and maintenance-free
• Optional reduction of the torsional stiffness through the use of two elements
• Compensation of axial, radial and angular misalignments
• Light-weight construction through the use of high-strength aluminium
• Variable mounting lengths through telescopic intermediate shafts, freely pluggable
• For use up to TKN depending on the application

The highly fl exible, torsionally optimised TOK couplings are specifically designed for use on test benches.
Radial and axial loads are supported by the bearing arrangement (2) towards the output end. Low-backlash spherical bearings (2a) exactly centre the drive end and the output end relative to each other in a true running manner. Alternatively, the spherical bearings (TOK-S) can be replaced by an integrated rolling bearing (TOK-B) (2b). The highly fl exible coupling element (3) is designed as a rubber-metal bond between the inner sleeve (3a). the rubber element (3b) and the outer ring (3c).
When torque acts on the drive end, the flexibility of the rubber element enables relative twisting against the output end. Torsional vibrations from the drive are thus efficiently de-coupled from the output end.
Besides the standard types, customised special solutions can also be realised with the TOK coupling system.

Coupling selection
A safety factor of SM = 1.3 should be applied if the coupling size is preliminary selected according to the continuous engine power to be transmitted. It is recommended to consider the nominal engine drive torque TAN and the maximum coupling torque occurring in service for the layout. The coupling size selection for test bench applications should be verified by a torsional vibration analysis which we will conduct on request. For compiling the details, please use the sheet ‚Details for coupling selection and torsional vibration analysis‘ on the last page.For long test bench shafts, the bending critical speed should also be taken into account. Basically it is the operator’s duty to observe the safety rules and regulations applicable to the specific case of application.
The nominal torque TKN of the coupling should be at least equal to the maximum engine drive torque TAN at any operating temperature and any operating load.The temperature factor St allows for a decreasing load carrying capability of the coupling due to elevated temperatures in the immediate vicinity of the coupling.
The service factor SB is to be determined according to the frequency of the start/stop operations and the occurrence of high accelerations. For standard operations (< 6 x start/stop per hour). a service factor of
SB = 1.1 is adequate. Service factors for higher frequencies on request.
The torsional vibration analysis to verify the coupling selection should confirm that the permissible continuous fatigue torque TKW of the coupling is at least equal to the maximum fatigue torque TW occurring in the operating speed range, whilst taking into account the temperature and frequency.
The frequency factor Sf allows for the frequency dependence of the permissible continuous
fatigue torque TKW (10 Hz) at operating frequency fx. Design solutions for engines with a low number of cylinders (1-. 2- and 3-cylinder engines) on request.
Take care not to continuously operate the system at resonance frequency of the test bench to avoid damage to the coupling, the test objects and the test bench components.

Assembly and maintenance instructions
General
The highly flexible TOK test bench coupling is predominantly used for de-coupling excitation vibrations of the load machine. The TOK coupling shaft is capable of compensating for axial, radial and angular misalignments. Shafts with joints integrated in the coupling body, cardan shafts and constant velocity shafts may be employed.
The rubber element is suited for ambient temperatures between –40 °C and 80 °C.
Care should be taken to ensure that the permissible loads of the couplings and of the intermediate shafts are not exceeded in any operating condition. Compliance with this requirement should be verified by a torsional vibration analysis and, where appropriate, by verifying the bending critical speed. The respective equipment confi guration must be verifi ed for each test object featuring different properties.
The coupling is balanced to a balance quality of G = 6.3 for 4000 rpm.
Specifi c balance quality requirements can be satisfi ed on request.
The speed range below idle speed must be quickly passed through during the start/stop operations to avoid excitation of potential resonance points. The coupling can be damaged if the speed range is passed through too slowly by one resonance especially during the start/stop operations.
Assembly
The contact faces must be metallically bright and free of grease and oil. Therefore, clean the connection and mating surfaces of the coupling which are preserved with corrosion protection wax, with suitable solvent before commencing assembly. Make sure that neither the solvent used for cleaning nor grease or oil can come into contact with the rubber. Where appropriate, pay attention to the position marking during assembly.
The maximum permissible coupling misalignment limits may not be exceeded in service. The respective limits are specified on the as-built drawings. In the case of cardan shafts take care that the primary and secondary axes are aligned in parallel. During assembly, it is recommended to utilise only 20% of the permissible misalignment capability.
Joints of cardan shafts and CV shafts regularly require small angular movements for adequate lubrication of the inner rolling elements. In the case of fl exibly mounted engines, these movements are ensured by the operational engine misalignments. Likewise, the movements occurring in the event of frequent test object changes may be suffi cient for adequate lubrication.
In the case of rigidly mounted engines or the use of intermediate bearings, an adequate angular movement must be provided by introducing a deliberate angular misalignment at each joint. For cardan shafts of type B, a parallel offset of the drive axis and the output axis corresponding to an angular misalignment between 0.5° and 1° per joint is recommended.
When using coupling shafts of type S-CV, only the CV shaft joint should have an angular misalignment of 0.5° to 1°. The coupling element should be operated, as far as possible, without angular misalignment to avoid additional power losses in the rubber. When aligning for assembly, the side to which the CV shaft joint is mounted should therefore be provided with an angular misalignment whereas the axis of the coupling is oriented in alignment with the axis of the connected intermediate shaft.
Before starting up make sure that all bolted connections of the coupling are tightened to their specified tightening torques. For the relevant tightening torques, see the as-built drawings.
Bolted connections which have been tightened to their specifi ed torques are marked with a dot of yellow lacquer at the factory. Bolted connections which have been secured by adhesive bonding, are additionally marked with a dot of green lacquer. These connections should only be checked visually for tight fi t. All non-marked bolted connections should be checked for their specifi ed tightening torques and for tight fi t using appropriate means. For bolts of the strength grades 8.8 and 10.9, see the tightening torques for bolted connections specified in Table 1.

The coupling shaft can be matched to the designated mounting space thanks to the telescopic capability of intermediate shafts. Make sure that the maximum values of the telescopic length are not already reached at standstill. It is recommended not to fully utilise the maximum telescopic length. There must remain a buffer of at least 5 mm to provide the clearance required for operational movements. Some of the dimension tables state the shortest possible mounting lengths which are already inclusive of that buffer and can be applied as stated. Follow the respective assembly and maintenance instructions for the cardan shafts or CV shafts in use.
Operation
Observe the specified operating conditions (torques, speeds, start/stop operations) when starting up. It is recommended to start with runs under stepwise increasing load conditions (such as speed sweep with high resolution torque detection and temperature monitoring on the element surface(s)). During this operation, pass the desired speed spectrum step by step while observing the test bench in order to identify any resonance points lying in the operating speed range. These resonance points and their surroundings should be spared when determining the test programmes to avoid damage to the coupling and the test bench components. They can, however, be passed through quickly. Repeat the runs under stepwise increasing load conditions each time a test object featuring different properties is used.
Maintenance and wear inspection
The coupling should be regularly inspected visually within the scope of routine maintenance and inspection. The rolling bearings, the spherical bearings and the sliding bushes of the coupling are maintenance-free. Subject the coupling to a thorough inspection in the case of irregularities (such as visible damage or delaminations from the rubber element or vibrations occurring whilst in service). If required, the coupling may be stripped after consultation with the manufacturer.
Check the visible rubber surface of the coupling element for potential damage. Inspect the bonded areas of the inner sleeve and outer ring for incipient cracks and delaminations. If damaged, replace the coupling element. It is advisable to also replace the bearing arrangement at that point of time. Spare parts kits containing all wear parts are available on request.
Subject the coupling/coupling shaft to an operational balancing process in the mounted state or, alternatively, balance it in the dismantled state, should conspicuous vibrations occur after replacement of the worn-out parts and re-assembly.
Thoroughly clean the coupling during maintenance. Factory overhauls and repairs of the coupling are possible on request.
Safety precautions
lt is the customer’s and operator’s responsibility to observe the national and
international safety rules and laws. Proper safety devices must be provided
for the coupling in accordance with the accident prevention regulations to
prevent accidental contact.
Check all bolted connections for tight fit and the correct tightening torque
after the fi rst test run and regularly thereafter.
