Rolling bearings are characterized by their special manufacturing processes. The inner and outer rings of the bearing are selected from high-quality steel, and the operation of the heat treatment process makes the inner and outer rings reach the required level of hardness and softness. The grinding process is to polish the inner and outer rings of the bearing, so that the two surfaces will not be scratched when rolling, and the size and surface quality of the bearing can also be ensured.
After finishing the bearing, the bearing needs to be tested. Generally, it needs to be tested before the bearing leaves the bearing manufacturer. Generally, it adopts the method of unstressed condensation. This method mainly simulates the parameters of the bearing operating environment, and inspects the performance of the bearing. At the same time, static tests such as dynamometer and rotation rig tests are performed to test the performance of the bearing.
In the rolling bearing assembling process, the surface of the bearing and the shaft must be handled properly, so as to reduce the friction coefficient between the bearing and the shaft surface. To ensure that the bearing can rotate freely and flexibly, it depends on the lubrication properties of the lubricant and the lubricant’s ability to protect.
The key point that affects the quality of the bearing installation is to accurately orient the bearing. There are special tools and methods to be used when installing the bearing: first use an inverted shell to fix the bearing. In order to prevent the bearing from oscillating and blocking during installation, apply some pressure on one side by auxiliary tools. Then use the special tools to press the bearing onto the shaft accurately.
The quality of the bearing installation depends on whether the relevant processes are operated according to the regulations, and whether the parameters such as accuracy level, fit size and lubrication condition are within the specified range. If it does not meet the requirements, the bearing is prone to damage and cannot be used normally.
In summary, the rolling bearing process is characterized by its special manufacturing processes. To ensure the normal operation of the bearing, it is necessary to install the bearing correctly, control the inner and outer surfaces of the bearing, pay attention to the surface accuracy of bearing and shaft, select and use the lubricating oil correctly, and test the bearing before leaving the bearing manufacturer.
