Finite Element Analysis and Test Correlation for Pressing and Staking of Planetary Gear Pinion Shaft

During the assembly process of planetary gears, the pinion shaft is initially pressed in to the planetary carrier and then staking is performed to fix the pinion shaft to the carrier. The main purpose of the staking process is to prevent the movement of the pinion shaft during transmission operation. During assembly there should be minimal distortion of the assembly. The press-in process, pinion shaft and carrier are subjected to extremely high …
