Drive components for demanding railway technology

Series production for Russian diesel locomotive

The company Reich-Kupplungen is supplying the Arcusaflex coupling to the manufacturer of the ТЭМ14 diesel locomotive in stages. The highly flexible, axially pluggable flange coupling acts as a connection between the engine and the driven machine. Each engine unit consists of two independently working aggregates, each with an 8-cylinder 4-stroke diesel engine and traction generator. 160 couplings therefore come together each year for the planned production of 80 locomotives.

Assigning the series supply to the Bochum-based coupling specialists demonstrates great confidence in the drive components. One advantage of the Arcusaflex, for example, is the highly flexible transmission element that is installed by means of plug-in assembly. It consists of a disc-shaped rubber body with torque-to-bore volume ratio. This dampens torsional vibrations to a large extent and enables the compensation of misalignments at operating temperatures up to 80 ºC. Thanks to functions and advantages like these, Reich-Kupplungen has been able to successfully prevail with its coupling over the manufacturer of the product previously used.

Flexible use in a temperate climate

The high performance of 2,400 hp qualifies the ТЭМ14 locomotive series to be used for shunting services, the transport of heavy goods as well as for mainline services on railways with a track width of 1,520 mm. The ТЭМ14 is used in regions with a temperate climate. It generally operates without any problems at outdoor temperatures of –50 °C to +40 °C.

New request for the ТЭ8 series

Some new examples of the ТЭ8 diesel locomotive are also required on Russia’s railway tracks in addition to the broad gauge ТЭМ14. The manufacturer has requested delivery of 100 Arcusaflex U-joint couplings for this. It is now over to Reich-Kupplungen.
