Aiming at the problems of motor bearing bit wear and end cover bearing room wear, traditional solutions such as machining after repair welding, inlaid bushings, brush plating, spraying, pitting, scrapping, etc., although these methods cope with the production to a certain extent Yes, but none of them can fundamentally solve the problem, and it also buried hidden dangers for safe continuous production, such as high-temperature deformation, cracks, and coating shedding. At the same time, the continuation of these traditional methods will not bring substantive equipment management work Promote.
Common ones are: bearing position, bearing chamber (seat), keyway and other moving surface wear and so on.
The main reasons for motor shaft wear are as follows:
- The equipment is installed, overhauled, lubricated and other reasons that are not standardized, untimely, or not in place, causing rapid equipment wear;
- Affected by vibration, pressure, impact and other forces, resulting in impact wear of the matching parts; due to the high strength of the metal material and poor concession, long-term operation will inevitably cause the gap to continue to increase, so wear, cracks, fractures, etc. It can’t be avoided
- The manufacturing quality is not high, and the heat treatment fails to meet the requirements, causing abrasion, and the shaft head may be broken in severe cases.
