How to Inspect a Gearbox - machinerylubrication

Measure Gear Backlash and Shaft Endplay. Measure gear backlash by mounting a dial indicator so it is similar to a pinion tooth profile, block the gear to prevent its rotation and rock the pinion through the backlash. To measure shaft endplay, mount a dial indicator at the end of a shaft and move the shaft in the axial direction.

RING GEAR TOOTH PROFILE There are two types of gears .

The TOE of the gear is the portion of the tooth surface at the end towards the center. The HEEL of the gear tooth is the portion of the tooth surface at the outer-end. The TOP LAND of a gear tooth is the surface of the top of the tooth. Every gear has a characteristic pattern. There are two types of gears which are determined by the machining ...
