Three shaft holes are formed in the disc part 12 along the axial direction of the gears 15. The three shaft holes are respectively arranged corresponding to the axial lines of the three gears 15. The shaft holes penetrate the top of the disc part 12, so that the rollers 16 are inserted into the center of the gears 15 from top to bottom. The shaft holes form grooves on the lower side walls of the windows 13 downward. When the rollers 16 are installed in place downward, the lower ends of the rollers 16 are fixedly inserted into the grooves.

[0031] With reference to Figure 2 and Figure 3 , the feeding mechanism comprises a fixed seat 21, a feeding track 22 and a feeding cylinder 24. The fixed seat 21 is provided with a mounting hole 23 for the shaft part 11 of the planet carrier to be inserted from top to bottom, so that the shaft hole of the planet carrier is arranged with the opening upward. The feeding track 22 is arranged in a set straight line direction on the device platform. The fixed seat 21 is connected to the feeding track 22 and can move along the feeding track 22. The feeding cylinder 24 is connected to one side of the fixed seat 21 and is used to drive the movement of the fixed seat 21 along the feeding track 22.

[0032] The two ends of the straight line direction of the feeding track 22 are respectively arranged in the gear feeding station and the roller feeding station.
