Background
The impact and significance of the quality of the bearing assembly on the operation of the equipment is very important. A properly assembled and quality bearing system ensures the reliability and stability of the equipment. Bearings are critical components in mechanical devices that directly bear the load of rotating or moving parts. If the bearings are improperly assembled or of poor quality, excessive friction, wear or loosening of the bearings during operation may result, thereby increasing the risk of equipment failure.
In the operation and maintenance process of equipment, a bearing is often a main concern of machine repair operation and maintenance as a part which is extremely easy to damage. The quality of the mounting of the bearing directly affects its accuracy, service life and performance. However, in the current field of steel manufacturing, the replacement of bearings is often dependent on manual hammering using a hammer, and there are a number of problems in this operation, including the susceptibility of the bearings to damage, low installation efficiency, difficulty in ensuring the installation quality, and the like. Because the structure and the size of the bearing are different, the installation process should be reasonably arranged according to the specific situation and the matching property of the bearing. In general, the pressure should be applied directly to the end faces of the ferrules that are in close fit, rather than being transmitted through the rolling elements. This accurate pressure application method ensures that the bearing is not subjected to unnecessary stress and deformation during installation. However, the current installation of a manual chisel with a hammer has a number of disadvantages. First, the impact force during hammering can generate a large impact load, which is very likely to cause damage to the bearing. Such damage may be manifested as dishing of the inner and outer races, scratches or deformations of the raceway surfaces, etc., directly affecting the accuracy and service life of the bearing. Second, uncertainty in manual operation causes difficulty in ensuring installation quality. The applied force and direction cannot be accurately controlled, so that the bearing is easy to install unbalance or unstable, and the performance and the running stability of the bearing are further affected. In addition, the manual hammer chisel mode has lower installation efficiency and can not meet the requirement of the modern industry on high-efficiency production.
