The fixing method of needle bearing should be considered in the combination design of needle rolling manufacturers

Pin specifications should be fully used in the equipment. In addition to selecting the type and model specifications that are consistent with the system software, proper overall design should also be carried out. What is the content of the design plan of cylindrical roller bearing?

The overall design of cylindrical roller bearing consists of the structure of the supporting plate end of the shaft system, the lubrication and sealing of the rolling bearing, and the improvement of the bending rigidity of the rolling bearing system software, which are all the overall objectives that must be exceeded, otherwise the cylindrical roller bearing will not be able to operate normally.

In addition, there are also fixed methods for cylindrical roller bearings. If the two sides are fixed, each bearing bears a bearing direction force, which allows small amount of thermal deformation when the shaft is working. When the cylindrical roller bearing is announced to be installed, a radial clearance of 0.25mm-0.4mm shall be left. The actual pin connection can be adjusted according to the gasket or screw.

If only one end of the cylindrical roller bearing is double fixed, and the other end has to maintain the swing, it can ensure that the rolling bearing can swing at will under the condition of retractable type. The key is the double radial force borne by single rolling bearing or rolling bearing group. In order to prevent loosening and falling off, the inner scope and shaft of swing rolling bearing are fixed.

In all structures, the applied cylindrical roller bearing is used as the swing supporting point, and the outer side of the rolling bearing must be fixed with the motor shaft as the pin hole. With the help of the swing between the roller bearing and the ferrule, the rolling bearing can be freely retractable, and all the normal operation of the rolling bearing can be ensured.
