Description
Technical Field
The invention relates to the technical field of cages of bearings, in particular to a cage of a cylindrical roller bearing and a using method thereof.
Background
A rolling bearing is a precise mechanical element that changes sliding friction between a running shaft and a bearing housing into rolling friction, thereby reducing friction loss. The rolling bearing generally comprises an inner ring, an outer ring, a rolling body and a retainer, wherein the retainer plays a role in uniformly isolating the rolling body and guiding the rolling body to move.
The bearing cage of a rolling bearing is generally composed of two side rings arranged at a certain distance in the axial direction and a plurality of lintels which connect the side rings and are arranged in succession in the circumferential direction of the bearing cage, the lintels forming pockets for accommodating the rolling bodies in pairs, the bearing cage holding the rolling bodies spaced apart from one another by the pockets provided for this and preventing direct contact of adjacent rolling bodies, which can effectively reduce friction and heat generation in the bearing, in addition the cage enables the rolling bodies to be distributed equally over the entire circumference of the cage or rolling bearing and enables a balanced load distribution and stable and balanced operation, the rolling bearing cage being mechanically subjected to very strong frictional forces, tensile forces and inertial forces during operation, which can also be caused by chemical reactions generated by certain additives and substances under certain circumstances, and therefore, for the functional realization of the cage and also for the operational reliability of the bearing, the shaping and material selection play a decisive role overall.
With the popularization of bearings, the advantages and disadvantages of rotating shaft retainers begin to appear, for example, when a rolling bearing is installed, a machine is required for installation, the operation is troublesome, the roller is damaged due to excessive friction of the bearing, generally, only the bearing can be replaced, and the damaged bearing can only be discarded, so that resources are seriously wasted.
