Bearings radial, in addition to the location of contact with the box, there is no other way?
10, to prevent the bearing in axial load axial movement, bearings on the shaft and outside the Nanning hole are applied axial positioning device. Bearings on the shaft and the selection of the location of the shell depends on the size and direction of the load on the shaft, the speed of the bearing, the type of bearing, the position of the bearing on the shaft, etc.. The higher the axial load, the higher the bearing speed, the more reliable the axial alignment. For different types of bearings, axial positioning should also be different. Such as diagonal contact ball bearings and tapered roller bearings, shoulder and shell holes can be used to shoulder one-way support, without the use of special positioning device, the ring in the axial movement can be supported by the bearing itself. As a fixed support radial bearing, the inner and outer rings are fixed on the left support in the axial direction. As a traveling support that needs to compensate for the thermal elongation of the shaft, if a separable bearing is not installed, only one of the rings needs to be fixed, and the traveling ring is not fixed. Separate bearings, such as short cylindrical roller bearings and needle roller bearings, are installed in the traveling support, and all two rings need to be fixed. Bearing bearing ring used to positioning method is described as follows: 1. the bearing inner ring mounted on the shaft bearing inner ring, generally by the shaft in a fixed bearing position, and the other side with nuts and washers or spring retainer ring fixed.
2. the outer ring of the bearing outer ring of the bearing outer ring is arranged in the outer hole of the outer shell, and the inner side of the outer hole of the outer shell generally has the position of the shoulder fixed bearing, and the other side is positioned with an end cover, a thread ring and a hole, and an elastic ring ring. (1) the end cover positioning end cover is used for all kinds of radial bearings and angular contact bearings. When the bearing speed is higher and the axial load is larger. The end cover is positioned and pressed with a screw to compress the outer ring of the bearing, and the end cover can also be made into a labyrinth sealing device. (2) thread ring bearing high positioning speed, axial load, not suitable for use under the condition of end cap positioning, available thread ring positioning radial bearing and thrust bearing, this can be used to adjust the axial clearance of the bearing. (3) the axial position of the elastic ring positioning method is small, the installation and disassembly are convenient, the manufacture is simple, and the utility model is suitable for bearing smaller axial load places. An adjusting ring is added between the bearing and the spring, so that the axial position can be adjusted conveniently. (4) the deep groove ball bearing with a stopping groove on the outer ring of the bearing can be fixed by the retaining ring. This type shall be used when the inside of the housing hole cannot be machined because of the condition limit, or the part must be reduced in outline size
