The needle roller manufacturer tells you about the needle roller bearing on the car and how to fix it

A car can run normally, it must have many high-precision parts, and hollow pin shaft is the top priority in this kind of parts. Each vehicle is equipped with different rolling bearings, resulting in the application of different rolling bearings. The running position of the vehicle, the front and rear four-wheel rolling bearings are indispensable; the rear axle of the vehicle type end rolling bearings; transmission type, output end rolling bearings; one axle, two axle rolling bearings, the natural use of more rolling bearings is still in the transmission, the number of rolling bearings in each vehicle It has a very important effect.

In order to make the achievements of rolling bearing in the equipment fully used, in addition to selecting the types and types consistent with the management system, it is also necessary to carry out the appropriate overall planning of composition and structure. This cylindrical roller bearing is the same. The overall planning of the composition and structure of the cylindrical roller bearing includes the end structure of the supporting plate of the shafting; the cooperation between the pin bolt and the relevant parts; the smoothness and sealing of the rolling bearing; and the development of the bending rigidity of the rolling bearing management system. These are all strategic policies that require more than, otherwise, the cylindrical roller bearing will not be able to be all normal Work.

In addition, there are also fixed ways of cylindrical roller bearings. If the two sides are fixed, each rolling bearing receives a direction of rolling bearing force. At this time, it is agreed that the shaft has a small amount of thermal deformation when working. During the period of announcing the cylindrical roller bearing of the equipment, a radial clearance of 0.25mm-0.4mm shall be reserved, which can go through the maintenance of the gasket or screw.

However, this kind of fixed fixed way will restrict the double movement of cylindrical roller bearing, so it is generally suitable for some shafts with little change of working temperature. In the application period, it is also necessary to consider the hot stretching and the compensation gap between the rolling bearing cover and the outer inner hole.

If only one end of the pin shaft is double fixed, and the other end is kept swinging, the rolling bearing can swing freely during the period of ductility. The key of fixed fixed end of cylindrical roller bearing is the double radial force accepted by single rolling bearing or rolling bearing group. In order to avoid loosing and falling, the inner category and axial direction of swing rolling bearing are fixed.
