It can simulate planetary gear cracks, broken gear, pitting, wear (gear clearance increase) and other fault simulation, a separate layout is not affected by other rotor structure, the signal is pure, no other sources of vibration to interfere with the results of data acquisition and analysis. Single-stage drive, reduction ratio：1：10 Input the number of sun gear：12 gear* 1 set Number of planetary gears：48 gear* 3set Number of ring gears：108 gear
