Squirrel-cage type toroidal planet globoidal cam transmission device

Abstract

The invention discloses a squirrel-cage type toroidal planet globoidal cam transmission device, and relates to the technical field of transmission devices. The squirrel-cage type toroidal planet globoidal cam transmission device comprises an input shaft, the lower end of the input shaft is fixedly connected with the upper end of a central globoidal cam, a plurality of planet gears matched with the central globoidal cam are uniformly distributed in the circumferential direction of the central globoidal cam, and the central globoidal cam is perpendicular to the axial direction of the planet gears. A plurality of rolling bodies are arranged on the circumferential surfaces of the planet gears, a plurality of curved rib plates matched with the rolling bodies are arranged on the outer sides of the planet gears, each planet gear is arranged at the upper end of a planet carrier corresponding to the planet gear, the lower end of each planet carrier is fixed in the circumferential direction of an output shaft, and the upper end of the output shaft is fixed at the lower end of the central globoidal cam. According to the squirrel-cage type toroidal planet globoidal cam transmission device, on the basis that original transmission advantages are guaranteed, machining and assembling are easy, and the advanced mechanism can be widely applied conveniently.

Description

technical field [0001] The invention relates to the technical field of transmission devices, in particular to a squirrel-cage toroidal planetary arc cam transmission device. Background technique [0002] The toroidal planetary worm transmission was first proposed by M.R.Kuehnle in the United States in 1968. It is mainly composed of two parts: one part is the center worm assembly composed of the center worm, planetary gear and planet carrier; Arc surface concave groove stator (referred to as stator) composed of arc-shaped parts. The transmission integrates rolling contact technology and planetary worm transmission technology. In principle, it has the advantages of compact structure, small size, light weight, low noise, high bearing capacity, wide range of transmission power and transmission ratio, and high transmission efficiency. The best form of mechanical transmission known. [0003] But this kind of transmission mechanism has the following problems: 1. The transmission ...

AI Technical Summary

Problems solved by technology

[0003] However, this kind of transmission mechanism has the following problems: 1. The transmission device is very difficult to manufacture, and the processing of the internal spiral groove of the stator, which is a key part of the mechanism, is the most difficult

2. Due to the manufacturing and installation errors of the system parts themselves, the load distribution of the system is not completely uniform, so that a certain planetary gear bears a large load, which is prone to broken teeth, causing damage to the bearings, and manufacturing and installation errors will also cause the meshing line of the gear pair to be damaged. Load changes, load changes will cause system vibration and noise
