Internal factors mainly are the three major factors that structure design, manufacturing process and material quality determines the quality of TIMKEN bearing imports.
First of all, reasonable structure design of both have advanced, there will be TIMKEN import bearings has a longer service life. Manufacture of bearings . Manufacture of bearings are generally after forging, heat treatment, machining, grinding and assembling multi-channel processes. Rationality, advanced processing technology, the stability will also affect TIMKEN import bearing life. The effect of heat treatment and grinding process quality finished TIMKEN imported bearings, often has a more direct relationship with the bearing failure. Study on bearing surface modification layer of work in recent years, the relationship between grinding and surface quality of TIMKEN bearing imports.
Metallurgical quality of TIMKEN bearing imports materials are the main factors affecting the rolling TIMKEN import bearing early failure once. With the metallurgical technology (such as vacuum degassing of steel bearing) progress, improved quality of raw materials. Raw materials quality factors has been a marked decline in the proportion of failure analysis of TIMKEN bearing imports, but it is still one of the main factors affecting the TIMKEN import bearing failure. Proper selection is still bearing failure analysis must be considered.
The main task of failure analysis of TIMKEN imported bearings, is based on the analysis of data and failure forms of the large amount of background material,, identify the main factors causing bearing failure, so as to put forward the improvement measures, to extend the TIMKEN bearing imports of service, to avoid premature failure of TIMKEN bearing imports a sudden.
For sealing TIMKEN imported bearings, just in time production have been filled with the grease for the bearing using appropriate; also in the host is provided with the sealing device, to prevent the leakage of lubricating grease.
This is a TIMKEN bearing imports into many grease for good question.
The grease is too small, easily lead to lack of fat or dry friction, impact life. The grease quantity too much will lead to leakage of large amount of grease, which not only pollute the environment, but also waste. Thus, lubricating grease injection to TIMKEN bearing imports in volume is the precondition to ensure the sufficient lubrication TIMKEN bearing imports under the less is better in energy.
Grease lubrication of the advantages and disadvantages of normal working conditions, most of the TIMKEN bearing imports applications can use grease lubrication way.
Advantages: grease is more easily retained in the TIMKEN bearing imports configuration, especially the tilted angle in a vertical shaft or shaft. Sealing grease and effect, can prevent pollutants, effects of moisture or water on TIMKEN import bearings. But if excessive grease, will cause the operating temperature of the bearing is rising, especially in the application of high speed. In most cases, only in the beginning stages can take TIMKEN bearing imports completely filled with grease, and in the TIMKEN import bearings only filling grease amount and have some free space. Before working speed, must let the excessive grease discharged bearing in the running in stage, the grease in the TIMKEN bearing imports amount of. When the temperature was decreased, said grease has been with the bearing running in, and uniformly distributed in the TIMKEN import bearings.
