Abstract
The utility model discloses a differential gear tooth side clearance measuring device which mainly comprises a detection plate, a connecting rod, a spring, a rotating shaft and a sector plate, wherein the connecting rod sequentially penetrates through the detection plate, the spring and the rotating shaft and then is fixedly connected with the sector plate; the detecting plate is fixed at the upper end of the connecting rod. The rotating shaft goes deep into an inner hole of the differential assembly, a spline at the lower part of the rotating shaft is matched with a spline hole of the half axle gear, the rotating fan-shaped plate is clamped on the end face of the half axle gear by rotating the fan-shaped plate, then the measuring device and the differential gear are fixed into a whole by the adjusting nut, after the dial indicator frame is fixed on the detection plate, the amount of exercise of the detecting device is measured by the up-down displacement of the connecting rod, and then the tooth side clearance of the differential is measured. The utility model has low manufacturing cost; the device is simple to operate. The design can be applied to other differential gear products, and can be applied to measuring any differential gear product through simple size conversion according to different products.
Description
Technical Field
