The radial runout of the gear ring affects the accuracy of the gear drive, so the gear is to be checked on the shaft and the runout of the end face.
The gear detects the radial runout of the gear ring; it is the pulsation of the teeth of the teeth or teeth; the radial circle of the smooth cylinder is the beating of the cylindrical surface
Therefore, after the gear is mounted on the shaft, check (A radial runout) and runout of the end face
The gear drive accuracy is affected by the radial runout of the gear ring
