Embodiment Construction

[0010] Such as figure 1 As shown, a submersible pump bearing of the present invention includes a bearing body and a bearing cover 1 installed on the shaft, the bearing body includes an inner shaft sleeve 2, an intermediate layer 3 and an outer shaft sleeve 4, and the inner shaft sleeve 2 One end is in contact with the shaft, the other end is perpendicular to the axis of the shaft, and the other end of the inner shaft sleeve 2 is an annular retaining ring 5, and the middle layer 3 is sleeved on the inner shaft sleeve 2, between the middle layer 3 and the inner shaft sleeve. Rolling elements 6 are installed on the contact surface of the shaft sleeve 2 , and the middle layer 3 and the inner shaft sleeve 2 are sealed and moved with each other, and the outer shaft sleeve 4 is sleeved on the middle layer 3 .

[0011] Wherein, when the bearing cover 1 is matched with the bearing body, the flange on the bearing cover 1 is embedded in the groove on the outer sleeve 4; the rolling eleme...

Abstract

The invention discloses a submersible pump bearing comprising a bearing body arranged on a shaft, and a bearing cover, wherein the bearing body comprises an inner shaft sleeve, a middle layer and an outer shaft sleeve; one end of the inner shaft sleeve is contacted with the shaft; the other end of the inner shaft sleeve is vertical to the axis of the shaft; an annular baffle ring is arranged at the other end of the inner shaft sleeve; the middle layer is sleeved on the inner shaft sleeve; and a rolling body is arranged at the contact surface of the middle layer and the inner bearing, and the outer shaft sleeve is sleeved on the middle layer. The submersible pump bearing disclosed by the invention is an improvement mainly aiming at the problem that the bearing is oxidized and rusts because of working in water for a long period of time; and the bearing is relatively stable in the working process by the unique structure design and installation and the hermetic arrangement of a rotating part of the bearing. Therefore, the service life of the bearing is greatly improved.

Description

technical field [0001] The invention relates to a submersible pump bearing. Background technique [0002] Bearings are components that fix and reduce the friction coefficient of loads during mechanical transmission. It can also be said that when other parts move relative to each other on the shaft, it is used to reduce the friction coefficient in the process of power transmission and keep the center of the shaft fixed. Bearings are an important part of modern mechanical equipment. Its main function is to support the mechanical rotating body to reduce the friction coefficient of the mechanical load during the transmission process of the equipment. Because the working environment of the bearing is different, it will be affected by environmental factors to a certain extent, especially if it works in water for a long time, the bearing is easy to rust and affects its service life, so it will have a certain impact on its work. Contents of the invention [0003] The te...
