Gearbox Test Rig

Gearbox/Transmission test beds are used for the final test and running of gearboxes prior despatch. Gearbox test rigs are designed, manufactured and commissioned by Incotech for a wide type of gearbox types including 2wd, 4wd, manual and automatic. Worldwide customers Include Caterpillar and JCB.

These pictures show a typical machine that was installed in the USA for gearboxes which is capable of testing 7 different types of gearbox.

This particular machine test sequence is controlled by a WMA software which records test results and data.

We also use VMC control software on many of our machines. There are many different options of control software available, and the choice of software/control manufacturer is down to customer preference.

The gearbox test rig uses a directly coupled electric motor to drive the transmission.

Pressure transducers are used to measure and in some cases calibrate oil pressures in the clutch packs and lube pressures within the gearbox.

Other gearbox test rigs:

Many gearbox/transmission rigs have been designed by Incotech to accommodate different gearbox designs. Some rigs apply an output load either electrically, pneumatically or hydraulically, and all feature an automatically loading headstock to enable easy loading and unloading of the gearbox and spline drives.

Other smaller rigs have been designed to run in gearboxes before use in the field. The test specification is determined by the customer and Incotech will ensure the test criteria is achieved.
