Local public transport with regional rail vehicles is part of the customer’s core business. Low maintenance costs and high train availability are crucial factors for the railway operator. Any downtime or delays can
mean considerable costs and financial penalties.

The challenge

To ensure the best possible availability, the gearboxes and wheels of all the wheelsets of a train, including its axle and gearbox bearings, are regularly inspected,
overhauled or replaced. The customer was therefore looking for a solution that would ensure the reliability and accuracy of checks, while also minimising the downtimes of the trains.

The solution

With its
special condition monitoring test rig for railway gearboxes and axlebox bearings, Schaeffler implemented a cost-effective solution optimised for the customer’s specific application. Schaeffler SmartCheck sensors are simply attached to the components to be monitored
using magnets and undertake precise measurements of vibration and temperature without a requirement for further installation outlay. Components monitored include gears in gearboxes, gearbox bearings, wheel axles and axlebox bearings.
