V-shaped slot follower plate of speed reducer

Abstract

The invention relates to a V-shaped slot follower plate of a speed reducer, and the V-shaped slot follower plate is applied to joint robots. The V-shaped slot follower plate comprises a follower plate body (7), wherein a transverse V-shaped rail (20) which is used for mounting a first crossed pin roller (5) is arranged on one surface of the follower plate body; and a longitudinal V-shaped rail (21) which is used for mounting a second crossed pin roller (8) is arranged on the other surface of the follower plate body. The transverse V-shaped rail and the longitudinal V-shaped rail on the follower plate body form a cross on plane space, and a cross angle ranges from 87.5 degrees to 92.5 degrees. The speed reducer can realize automatically regulating motion of an input shaft (an eccentric shaft) to completely fit to eccentricity, so that transmission rolling balls of the speed reducer completely fit to the track of a differential transmission, the output of the speed reducer is stable and a mechanical wear rate of the speed reducer is low; and the speed reducer has the advantages of a compact structure, low noise, light weight, a small size, stable and reliable transmission, high output precision and the like.

Description

technical field [0001] The invention relates to a mechanical transmission deceleration technology, in particular to a drive reducer applied to a joint robot. Background technique [0002] At present, most of the mechanical transmission reducers are driven by gears or worm gears. The main principle is to change the speed by changing the number of teeth of the gears. The defects and deficiencies of this type of mechanical transmission reducer are: due to the low machining accuracy of the transmission parts, there is a certain process gap in the design and installation process of the gear or worm gear reducer, which affects the output accuracy. The movement between them is in the form of a high pair, which is prone to problems such as mechanical wear, unstable transmission, loud noise, and poor output accuracy. [0003] In the Chinese invention patent application number 2015103631823 and the announcement number CN104964011A (application date: June 25, 2015) published on Octobe...

Problems solved by technology

The defects and deficiencies of this type of mechanical transmission reducer are: due to the low machining accuracy of the transmission parts, there is a certain process gap in the design and installation process of the gear or worm gear reducer, which affects the output accuracy. The movement between them is in the form of a high pair, which is prone to problems such as mechanical wear, unstable transmission, loud noise, and poor output accuracy.

However, the driving ball is prone to slight jumps when working, and its stability is poor, and it is easy to produce unsmooth output of the reducer, stepping vibration, high wear rate, etc.
