TOK - Reich Kupplungen

TOK-coupling system

Test bench couplings are applied in miscellaneous test benches. By reason of manifold, specific requirements TOK system is designed according to the modular design concept, to be applicable on almost every engine test bench.

For specific requirements, e.g. special-test benches, the standard parts can be combined with specific-designed parts to derive solutions corresponding to individual conditions.

Advantages of the TOK-ZW coupling system:

  • Lowest possible torsional stiffness utilizing two flexible elements
  • Simple adjustment of the torsional stiffness by changing of elements
  • Compensation of axial-, radial- and angular misalignment
  • Self-centering, backlash-free and maintenance-free
  • Flanges adapted to DIN or SPICER bolt patterns, respectively on demand
  • Variable installation lengths utilizing telescopic spacer shafts
  • Ideal for highest speed
  • Lowest possible weight by using high-tensile aluminium and CFRP

Product details

Einsatzbeispiel der hochelastischen Prüfstandswelle TOKGeneral technical description

For specific requirements, e.g. special-test benches, the standard parts can be combined with specific-designed parts to derive solutions corresponding to individual conditions.

The torsional stiffness can be easily changed and adapted by simply replacing the flexible elements, as well in service. The rubber element of the coupling is vulcanised to an inner and outer ring, thus enabling torque transmission without being affected by centrifugal forces at high speeds.

Types

AC – VSK cardan shaft - Standard application

Highly flexible coupling AC – VSK in combination with a cardan shaft for rotational speeds up to nmax = 7000 rpm. Seperate catalogue available.


AC – VSK cardan shaft - Standard application

TOK – ZW with intermediate shaft

Highly flexible double element coupling TOK – ZW with intermediate shaft for length adaptation of the space between engine and dynamometer. The coupling has got a low torsional stiffness and operates in case of axial, radial and angular misalignment as a cardan shaft. Rotational speed up to nmax = 10000 rpm.

New: Adaptive TOK-Docking-System for Engine Testing Your drive

More productivity, reduced rigging times, less operating costs – the new Docking-System from REICH-KUPPLUNGEN helps increase the efficiency of engine test benches.

This system is designed to automate the process of changing the test objects for combustion engine testing to the greatest possible extent. The time available for testing is thus maximised. This is made possible by a docking system which is based on the principle of modular construction. It is used to connect combustion engines of different sizes to a dynamometer. This way, engine testing is made easy.

 

Flexible docking and centering fixture
The special feature of the docking system is its selfdocking and self-centering fixture. It consists of a pin and a sleeve which are both straight-toothed. The two components are available in a standard size and mounted to a coupling matching the engine tobe tested.

Rigging additional engines while testing
This fixture allows for preparing other engines to be tested while one engine still undergoes testing. Rigging only involves the mounting of the matching coupling with the standard pins to the engine. Given that thiswork is performed outside the test bench area, the rigging times are minimised in the test cell.

Self-alignment and self-centering
The smartly designed centering attachments are able to compensate for an offset of up to 15 mm while docking. The CV-jointed sleeve on the dynamometer side rests on a support while the engine with the mounted TOK coupling and the toothed pins is slowly approaching its destination. While docking, the sleeve is lifted off the centering attachment and turned until the toothed components come into mesh.

Advantages of the adaptive TOK-docking system:

  • There is no longer need for complex mechanics and manual intervention on the dynamometer side. A correctly positioned, solid support is sufficient.
  • Rigging with time-consuming assembly operations takes place outside the test cell.
  • Rotational speeds up to 6,000 rpm are possible.
  • All toothed shaft components of a system come into mesh in any turning position while maintaining a good balance condition.
  • Centering attachments are available as spare parts and easily changeable.
  • The docking system can be extended to multiple test cells.
