Novel rotary supporting disc

Abstract

The invention relates to a novel rotating support disc, which comprises a thrust ball bearing, an upper pressing plate, a lower pressing plate and balls. The upper pressing plate and the lower pressing plate are buckled together, and they can rotate relative to each other. Balls and thrust ball bearings are buckled between the upper pressing plate and the lower pressing plate. There is a round hole in the center of the upper pressing plate and the lower pressing plate. The diameter is the same as the diameter of the inner ring of the upper bearing plate of the thrust ball bearing, and the diameter of the round hole of the lower pressure plate is the same as the diameter of the inner ring of the lower bearing plate of the thrust ball bearing. A retaining ring is provided on the inner side of the upper pressing plate and the lower pressing plate of the novel rotating support plate, and the inner side of the retaining ring and the outer side of the thrust ball bearing adopt clearance fit. The balls of the new type of rotating support disc are made of GCr15 material, the balls are provided with two rings, the number of balls in the inner ring is 14, and the number of balls in the outer ring is 22. The invention has simple structure and convenient use. It can be used in construction machinery and mining machinery.

Description

technical field [0001] The invention relates to a rotary support disc, in particular to a novel rotary support disc. Background technique [0002] In the mechanical rotary support structure, except for various types of bearings in the national standard, there are few components used for rotary support, especially in the field of radial large-scale axial load support. In today's axial load support, although the bearing standard parts can carry load, their radial load size is limited. In construction machinery and mining machinery, many axial loads are very large, and they cannot meet the requirements. Contents of the invention [0003] In order to overcome the existing deficiencies, the present invention proposes a novel rotating support disc. The rotary support disc has a simple structure, which can not only meet the requirements of rotary support, but also realize bearing axial load in the case of a large radial dimension. [0004] The purpose of the present invention i...
