Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of ball bearings and relates to a ball bearing assembly. Background Art
[0002] Ball bearings, also known as spherical bearings or ball bearings, are a type of bearing that can withstand radial and axial loads. Its design allows free rotation between the bearing seat and the shaft, and has a self-aligning function, that is, when the shaft is bent or installed out of center, the bearing can still work normally. There are steel balls between the inner and outer rings of the ball bearing, and the cage makes the steel balls evenly distributed. When the shaft rotates, the steel balls roll between the inner and outer rings, thereby realizing the rotational movement of the bearing. This design gives the ball bearing a high load-bearing capacity and a long service life. The ball bearing assembly is a key component widely used in various mechanical equipment, and its main function is support and rotation. Ideally, the ball bearing can effectively disperse and withstand pressure from all directions to ensure smooth operation of the equipment. However, when the ball bearing assembly cannot properly relieve external pressure, it may cause a series of problems.
[0003] Long-term pressure that exceeds its bearing capacity will cause the bearing material to fatigue, resulting in cracks or fractures. This will not only shorten the service life of the bearing, but may also cause sudden equipment shutdown and affect the normal operation of the production line.
[0004] Friction and overload can cause the internal temperature of the bearing to rise, which in turn causes thermal expansion. Thermal expansion can further increase the wear and damage of the bearing, forming a vicious cycle. If the heat cannot be dissipated in time, it may also cause the lubricant to deteriorate, further reducing the performance and life of the bearing.
[0005] Damage and wear of bearings can cause unstable rotation of equipment, vibration and noise. This will not only reduce the working efficiency of the equipment, but also may interfere with the surrounding environment and even affect the health and safety of operators. Therefore, a ball bearing assembly is urgently needed to solve the above problems. Utility Model Content
