How to measure the backlash of the driving and driven bevel gears on the main reducer of the car?

 When measuring the backlash of the driving and driven bevel gears on the main reducer, the fuse or soft metal sheet can be bent into an S shape, placed between the non-working surfaces of the two gears, and the gear is rotated to allow the fuse or The soft metal sheet enters into the meshing of the human gear teeth, and finally the fuse or soft metal sheet is taken out to extrude, and the thinnest thickness of the extruded zui is the tooth gap. For the sake of accuracy, more than 3 teeth should be measured on the circumference of the driven gear, and the average value should be taken. For a pair of new hosts, driven bevel gears (including a pair of new cars and a pair of new gears), the tooth gap is generally: 0.1-0.3mm, check the specific data in the maintenance manual. After use, the maximum tooth gap generally does not exceed 0.5mm, otherwise, new gears should be replaced in pairs.

The driving and driven bevel gears have high transmission efficiency, stable transmission ratio, large arc overlap coefficient, high load capacity, smooth transmission, reliable operation, compact structure, energy saving, material saving, space saving, wear resistance, low noise, long life, etc. features.

A dial gauge with a magnetic suction seat can also be used to measure the backlash of the driving and driven bevel gears on the main reducer of the automobile. Let the magnetic suction seat be fixed, the dial indicator head is vertically pointing to the back of a tooth of the driven bevel gear, fix the driving bevel gear, turn the driven bevel gear slightly, and watch the beating amount of the pointer of the dial indicator between the two teeth, That's the backlash.
