Affect the cylindrical needle roller bearing service life may be a lot of factors that could cause friction factors and internal sound has been further instructions. The main factors used to adjust installation, use and maintenance, maintenance, etc. to meet the technical requirements. According to the cylindrical needle bearing installation, use, maintenance, and maintenance of the technical requirements for the operation of the bearing contact load, speed, lubrication condition monitoring and inspection found that the direct cause of the abnormal returns to normal.
Installation conditions, one of the factors used in bearings is often caused by incorrect installation package between the various parts of the state change the loading capacity of the prime factors of the abnormal state of the bearing operating temperature, vibration, noise, progressive, and improved the quality of the original material . The proportion of the raw material quality factors bearing failure analysis has decreased significantly, but it is still one of the main factors of bearing failure.
Choose whether proper still must consider the bearing failure analysis. Cylindrical needle roller bearings manufacturing by forging, heat treatment, turning, lubrication conditions, in order to monitor and check abnormal findings directly to adjust back to normal. Conditions of the installation is to use one of the factors of the bearing is often caused by incorrect installation package between the various parts of the state changes in the loading capacity of the primary factors in the normal operating state, and the inner life of the early termination of the main factors, the structure design, quality manufacturing processes and materials, there are three factors that determine the quality of the bearings.
The main factors used to adjust installation, use and maintenance, maintenance, etc. to meet the technical requirements. Installation conditions using the rolling bearing one of the factors is often caused by incorrect installation package between the various parts of the state changes in the loading capacity of the primary factors in the abnormal state of operation and early failure. Bearing installation, use, maintenance, technical requirements the operation rolling bearing contact load, speed, temperature, vibration, noise and lubrication condition monitoring and inspection, abnormal immediately find out the reasons, to adjust back to normal.
The the cylindrical needle bearing materials metallurgical quality is a major factor in the early failure of rolling bearings. With the metallurgical technology advances (such as bearing steel, vacuum degassing, etc.), to improve the quality of raw materials. The proportion of raw material quality factors in Rolling Bearing Fault Analysis has decreased significantly, but it is still one of the main factors in rolling bearing failure. Whether it is appropriate must consider rolling bearing failure analysis.
Internal factors mainly refers to the structural design, quality manufacturing processes and materials, there are three factors that determine the quality of the rolling bearing.
First, the structure design and advanced at the same time, there will be a longer bearing life. Rolling manufacturing will go through the process of forging, heat treatment, turning, grinding and assembly operations. The rationality, advanced processing, can also affect the stability of the service life of rolling bearings. Influence of heat treatment and grinding process of rolling bearings tend to have a more direct relationship with roller bearing fault product quality.
The main task of the cylindrical needle bearing failure analysis is based on a lot of background material, data and failure mode analysis to identify the main factors causing rolling bearing failure in order to make targeted improvements to extend the service rolling bearing, in order to avoid the rolling bearing unexpected the event early failure.
