Abstract

The invention belongs to the technical field of planetary gear transmission, and specifically relates to a high-reliability bearingless planetary transmission device, which solves the problem that the existing planetary transmission device uses bearings to support the planetary shaft, and it is difficult to meet the strength requirements of each component under the limitation of space size. The problem. High-reliability bearingless planetary transmission device, including the sun gear, several planetary gears and planetary shafts matching the planetary gears are arranged outside the sun gear, the sun gear is meshed with the planetary gear, the planetary gear is meshed with the ring gear, and the planetary gear has no bearings It is directly installed on the planetary shaft, and the planetary shaft is fixedly connected in the planetary frame. The material of the planetary shaft is a high-strength wear-resistant copper-based alloy. The beneficial effect of the present invention is that the hole of the planetary wheel is directly matched with the planetary shaft, and the planetary shaft has both the functions of a shaft and a bearing, which can ensure small size and high strength.

Description

technical field [0001] The invention belongs to the technical field of planetary gear transmission, and in particular relates to a high-reliability bearingless planetary transmission device. Background technique [0002] Traditional planetary transmissions generally use double bearings to support the planetary shaft. The bearings are either placed in the planetary wheel or placed in the planetary carrier. The diameter of the asteroid shaft or the thickness of the outer wall of the planetary wheel and planetary carrier are difficult to meet the requirements for the strength and bearing life of the planetary wheel or planetary carrier, planetary shaft and bearing under certain space constraints. Contents of the invention [0003] In order to solve the problem that the existing planetary transmission adopts bearings to support the planetary shaft, it is difficult to meet the strength requirements of each component under the limitation of space size, and provides a high-reliab...
