Problems solved by technology

The disadvantage of the existing RV transmission is that the eccentric shaft is placed inside the internal gear, so that the size of the arm bearing on the eccentric shaft is limited by the diameter of the internal gear
At the same time, due to the harsh working conditions of the rotating arm bearings, the working life of the rotating arm bearings is relatively short, which often directly affects the life of the entire transmission device.

Embodiment Construction

[0024] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.

[0025] Attached Figure 1-1 and Figure 1-2 show the involute tooth-shaped new ring plate type RV transmission device, which uses three planetary gears 4 to mesh with the sun gear 3; three eccentric shafts 5 are mechanically connected to the corresponding planetary gears Gear 4; three coupling shafts 16 pass through the gear ring plate to mechanically connect the output shaft plate 11 and the load plate 7. The basic composition of the transmission device is: an open planetary transmission mechanism plus an eccentric differential transmission mechanism plus a parallelogram mechanism plus an output mechanism. The open planetary transmission mechanism consists of a sun gear 3 and three planetary gears 4 installed on the input shaft 2; the eccentric differential transmission mechanism consists of a middle internal gear ring plate 6, two internal...

Abstract

The present invention relates to a new ring-plate type RV drive equipment. It includes machine body, central gear mounted on the input shaft, planetary gear mounted on the eccentric shaft and meshed with central gear, internal gear ring-plate mounted on the eccentric shaft, load-equalizing plate which is passed through internal gear ring-plate and connected by means of connecting shaft, output shaft plate and bearing. Its structure also includes an external gear fixedly-mounted on the front end plate of machine body; the described internal gear ring plate is meshed with said external gear.

Description

technical field [0001] The invention relates to a hybrid planetary gear transmission. Background technique [0002] The existing RV transmission device is found in the invention patent disclosed by the Chinese Patent Office with the CN1366590A number: "Transmission device with internal meshing planetary gear structure" and the paper "The robot uses Research on high-precision RV transmission". The disadvantage of the existing RV transmission is that the eccentric shaft is placed inside the internal gear, so that the size of the rotating arm bearing on the eccentric shaft is limited by the diameter of the internal gear. At the same time, due to the harsh working conditions of the pivot arm bearing, the service life of the pivot arm bearing is relatively short, which often directly affects the life of the entire transmission device. [0003] In addition, there are only two external gear plates in the existing RV transmission. The inertial force generated by the eccentric shaf...
