Rolling sound and control the impact of the larger models of ball bearings or tapered roller bearings in a pure radial load at low speed, the centrifugal force due to rolling a smaller body, in a non-load zone of rolling elements will impact the cage or roller and noisy. But as speed increases, the sound will disappear. Impact on the rolling sound control methods are: appropriate to reduce the radial clearance, the use of a reasonable structure of supple material bearing cage.
Tapered roller bearings rolling rolling rolling rolling sound and sound control is a cylindrical roller bearings on all occasions possible harsh sound of metal rubbing, mostly in the grease-lubricated bearings in the larger models, and performance in the base oil more susceptible to deterioration of the lubricating grease, oil lubrication in almost no time.
First, the structure design has advanced with the same time, will have a longer life of tapered roller bearings. Manufacture of bearings generally through forging, heat treatment, turning, grinding and assembly of multi-channel processing operations. The reasonableness of the processing technology, advanced, will also affect the stability of the bearing life. Which affect the quality of the finished product bearing heat treatment and grinding processes, often associated with the failure of the bearing has a more direct relationship. In recent years, deterioration of the bearing surface layer of the study, the bearing surface of the grinding process and the quality of the close.
TIMKEN bearing metallurgical quality of the material used to affect the early failure of tapered roller bearings of the main factors. As metallurgical techniques (such as bearing steel vacuum degassing, etc.) and progress, to improve the quality of raw materials. Raw material quality factors in bearing failure analysis in the proportion has decreased significantly, but it is still bearing failure of one of the main factors. The appropriateness of the selection is still bearing failure analysis must be considered.
TIMKEN Bearing failure analysis of the main tasks is based on a lot of background material, analysis of data and failure mode, identify the tapered roller bearing failure caused by the main factors in order to make targeted improvements to extend bearing service period, to avoid bearing sudden occurrence of early failure.
