Robot matched flexible bearing structure

Abstract

The invention provides a robot matched flexible bearing structure. The robot matched flexible bearing structure comprises an outer ring, an inner ring, a holder and steel balls; the outer ring and theinner ring are coaxially arranged, the holder is arranged between the outer ring and the inner ring, the steel balls are embedded on the holder, the size of the steel balls is 1 / 2 to 3 / 4 of the widthsize of the section of the bearing, the ball filling angle ranges from 260 degrees to 330 degrees, a ball filling gap is arranged between the outer ring and the inner ring, pockets without lock openings and pockets with lock openings are arranged on the holder alternatively, and the same center diameter size is kept; the number of bearing steel balls is much, and the interval between two adjacentsteel balls is small, and the manner that spaced pockets are provided with lock points is adopted; in the mounting process of the holder, the steel balls enter the pockets through lock point extrusion, and the pockets without the lock openings have enough space to solve the problem that due to the f act that the steel balls extrude the pocket lock points, during assembling of remaining steel balls, the lock point deform space is too small.

Description

technical field [0001] The invention relates to the field of bearing structure design, in particular to a flexible bearing for a robot. Background technique [0002] Industrial robots are important automation equipment for modern manufacturing that integrates multi-disciplinary advanced technologies such as machinery, electronics, control, computers, sensors, and artificial intelligence. Robot technology and its products have developed rapidly and have become flexible manufacturing systems, automated factories, Automated tools for computer-integrated manufacturing systems. As one of the key accessories of industrial robots, industrial robot bearings have an important impact on key performance indicators such as the robot's smooth operation, repeat positioning accuracy, motion accuracy, and work reliability. The rotating speed of the supporting bearing of the robot is relatively low, and the space has been minimized. In the working condition that requires a large load, it is...

Problems solved by technology

It is difficult for ordinary bearings to greatly increase the rated load

[0003] At present, most of the supporting bearings for domestic industrial robots rely on imports. Although a few manufacturers produce supporting bearings for industrial robots, they have small batches, few varieties and specifications, low degree of generalization of parts, long supply cycle, high cost, and unstable quality. Factors seriously restrict the normal development of the domestic industrial robot industry
