What factors will affect the life of the high-speed motor bearing shaft
Author:admin Date:2023-02-15
High-speed motor bearings have higher precision and smaller surface roughness than ordinary bearings. The intuitive difference is that the surface of high-speed motor bearings is smoother than that of ordinary bearings. If the outer ring and inner ring shake, the clearance of the high-speed motor bearing is small.
1. What to do if the bearing of the high-speed motor is overloaded and heated
1. In the case of high speed or high temperature, the bearing and the state should be closely matched!
2. Use lubricating oil to reduce friction and load. High viscosity oil should be used when the working temperature is higher. Easy to form an oil film, thereby reducing heat generation!
2. Factors Affecting the Life of High Speed Motor Bearing Shaft
The length of the field installation test life of the bearing is mainly determined by the design and matching of the structural parameters of the bearing itself, as well as the manufacturing quality and process level of the product, but there are also some "non-bearing" factors that will lead to the reduction and failure of the field service life of the bearing. Through the analysis of the failed bearing, there are mainly the following points:
(1) The selection and installation level of the motor bearing by the assembler.
(2) The number of maintenance and disassembly of bearings. The same set of bearings has been disassembled and assembled many times, which will inevitably affect the service life of the bearings.
(3) The newness and oldness of the bearings and the differences in the quality of different manufacturers.
(4) The bearing itself is faulty, such as the wet weather in the south, which is easy to be damp and scorched.
(5) The lubricating oil for oil injection cooling contains impurities.
(6) Skills of machine tool operators, etc. For example: In the test, due to repeated operating errors, the oil was cut off, the grinding head was flooded, and the bearing was burned.
(7) Properly keep the bearings, such as severe corrosion of the bearings, pollution of the bearings, etc.
We know that ordinary bearings with a speed of 3000 can withstand it, and high-speed motor bearings can be assembled with a speed of more than 5000. High-speed motor bearings with less clearance are better suited for this type of work. The above is the introduction of high-speed motor bearings.
