AI Technical Summary

Technical Problem

Existing planetary carrier assembly tables cannot ensure the concentricity of the inner and outer gear rings, resulting in unstable installation and cumbersome operation.

Method used

The design employs a conical gear ring and a rotating cylinder. The conical gear ring is driven to rotate by a geared motor, causing multiple conical gears to rotate at the same speed and in the same direction. This drives the rotating cylinder and the movable rod to move, achieving concentric clamping of the inner and outer gear rings.

Benefits of technology

It enables rapid and stable concentric installation of the internal and external gear rings, simplifies the assembly process, and improves assembly efficiency.

Abstract

The utility model discloses a kind of assembly tables for planet carrier, it is related to assembly table technical field, including assembly table, the top central position of assembly table is provided with empty slot, and the top middle position of empty slot is equipped with mounting post, the inside of assembly table is provided with cavity, and the inside of cavity is provided with conical gear ring, the inner wall of cavity is fixed with multiple fixed cylinders.The utility model rotates by driving conical gear ring, so that multiple conical gears rotate at the same speed and in the same direction, and then multiple rotating cylinders rotate simultaneously, so that multiple movable rods can move the same interval inward or outward, so when the clamping of outer gear ring is completed by rotating roller, its center can be in the center of empty slot, then suitable mounting post is installed in the center of empty slot, and internal gear ring is sleeved on its outer wall, i.e. It can ensure that both are concentric, so that the edge interval of inner and outer gear ring is uniform, and each position can be quickly and stably placed into middle gear.
