Planetary Gearbox Test Rig

Planetary gearbox test rig

Test Rig Description

Figure 1 shows the planetary gearbox test rig. It consists of an induction motor, two planetary gearboxes, and a DC generator which is used to provide different loads to the test rig. The first planetary gearbox was used as a reducer with a transmission ratio of 5.76, and the second planetary gearbox was used as an increaser with a transmission ratio of 7.2.

Instrumentation

The signals measured from the test rig include, encoder signal, current, vibration signal from the planetary gearbox reducer, vibration signal from the planetary gearbox increaser and two temperature sensors on both planetary gearboxes (reducer and increaser). All signals are acquired with a 16-bit, 16-channel, and a sampling frequency of 100 kHz.

Typical Fault Simulation

The planetary gearbox test rig can simulate different types of faults, including sun gear and planet gear. Table 1 shows the fault types and the severities on the sun and planet gears. The fault simulation was performed separately (one fault at each time).
