Submersible motor with easily disassembled angular contact ball bearing

Abstract

The invention aims to provide a submersible motor with an easily disassembled angular contact ball bearing. The technical solution is that the submersible motor comprises a bearing support body and an angular contact ball bearing, the bearing support body comprises a bearing chamber, the angular contact ball bearing is located in the bearing chamber and comprises an outer ring, a ball and an inner ring, the bottom part of the bearing support body is provided with at least two screw holes, the screw holes are located at the bearing support body corresponding to the outer ring of the angular contact ball bearing and in axis symmetrical distribution. Another technical solution of the invention is that the submersible motor comprises a bearing support body and an angular contact ball bearing, wherein the bearing support body comprises a bearing chamber, the angular contact ball bearing is located in the bearing chamber, and the angular contact bearing comprises an outer ring, a ball and an inner ring. The submersible motor is characterized in that the angular contact bearing and the bottom part of the bearing chamber are provided with a base plate therebetween, and the base plate is provided with screw holes. The solution provided by the invention can enable the angular contact ball bearing of the submersible motor to be disassembled easily, thereby saving labor and effort, and reducing unnecessary loss caused by inappropriate artificial disassembling.

Description

technical field [0001] The invention relates to a submersible motor. Background technique [0002] A bearing is a component that fixes and reduces the friction coefficient of the load during mechanical transmission. It can also be said that when other parts move relative to each other on the shaft, the bearing can be used to reduce the friction coefficient and maintain the load during power transmission. The shaft center position is fixed. [0003] As a type of bearing, angular contact ball bearings have more advantages than ordinary bearings: simple structure, relatively high limit speed, relatively small frictional torque, can bear radial and axial loads at the same time, high rotation accuracy, and low noise. Therefore, angular contact ball bearings are widely used in submersible motors, and are also an important part of submersible motors. Its main function is to support the rotor to reduce the friction coefficient of mechanical loads during the transmission process of...

Problems solved by technology

[0004] Because the submersible motor is often in working condition and the working environment is harsh, the angular contact ball bearing is easy to wear and tear. Once damaged, it is very troublesome to replace the angular contact ball bearing

Because the outer ring of the angular contact ball bearing of the existing submersible motor adopts a transition fit with the bearing chamber, the inner ring, balls and cage are easily separated from the outer ring during disassembly, and it is very difficult to disassemble the outer ring alone in the bearing chamber, which seriously affects the work efficiency, and may even need to be replaced along with the bearing support, adding unnecessary cost
