If the angular contact bearing manufacturer does not pay attention during assembly, some small impurity particles may enter, and these impurities will be mixed into the grease of the bearing, causing friction during the operation of the bearing, resulting in noise, so high-end bearing production The manufacturer will complete the assembly process in a dust-free workshop; The second reason that may be overlooked is that the lubricating grease of the bearing is insufficient. If the grease is insufficient, the bearing will produce a certain cavity, resulting in local oil-free friction, resulting in comparison Therefore, angular contact bearing manufacturers must strictly control the amount of grease injected into the bearing during the grease injection process, and prevent grease leakage during storage. The third reason is that the bearing is installed incorrectly. Many machine tool manufacturers did not master the scientific installation method when installing the bearing. Abnormal vibrations and noises are generated during the operation, so our angular contact bearing manufacturers suggest using scientific installation methods such as the sleeve method, heating method, and oil pressure method; the fourth reason is that the clearance of the bearing is too small, if the clearance If it is too small, it will increase the friction generated by the rolling elements when they rotate, which will make the bearing more likely to heat up during use; the fifth reason is that the raceway is damaged, and the raceway processing of angular contact bearings is the focus of processing In the process, if the raceway is damaged, it will cause abnormal heating and noise, and in serious cases, it will cause early failure of the bearing. Professional angular contact bearing manufacturers will use microscope inspection to ensure that the raceway of each set of bearings is smooth and undamaged; The sixth reason is the problem of the bearing sealing ring. If the quality of the bearing sealing ring of the angular contact bearing is not good enough, or the installation is not in place, it will interfere with the normal operation of the bearing, resulting in a certain amount of noise and sometimes causing grease leakage. , In severe cases, it will cause early failure of the bearing. The seventh reason is the cage. If the cage of the angular contact bearing has poor accuracy or is damaged, it is easy to cause abnormal noise during operation. Therefore, angular contact bearing manufacturers will strictly control the quality of the cage before assembly. , in addition to inspecting each size, it will also carefully observe whether the appearance is smooth. Only when the torque is accurate can the rotation be stable! This article is from a limited company, please indicate the source and link (http:// ) for reprinting
