The other end of the pillar is assembled and fixed with the head and inserted in the pillar jack on the annular retainer cover, the wedge-shaped fixed ring is inserted in the pillar jack from the outside of the annular retainer cover, the wedge-shaped fixed ring is respectively matched with the inner wall of the pillar jack and the inclined conical surface of the assembled and fixed head, and the welding connection block is fixed at the outside orifice of the pillar jack. Compared with the traditional structure, the invention greatly improves the guiding of the inner holes of the support posts and the rollers and reduces the damage probability of the bearing due to the support posts and the rollers. The roller is more stable in the transition process of the roller from the non-load area to the load area, and the vibration of the bearing is reduced.
Description
Technical Field
The invention relates to the technical field of bearings, in particular to a welding strut retainer for a hollow cylindrical roller bearing.
Background
A welding strut retainer used for a traditional hollow roller bearing is characterized in that struts penetrate through roller middle holes and are connected with a retainer cover and a retainer seat, one end of each strut is in threaded connection with the retainer seat, and the other end of each strut is in welded connection with the retainer cover. The verticality of the support post is difficult to control in the actual machining process, so that the support post and the inner hole of the roller are abnormally worn or even damaged in the running process of the bearing. Due to poor guidance, the roller is not stable enough in the transition process from the non-load area to the load area, and vibration and noise of the bearing are increased.
Disclosure of Invention
The invention aims to solve the problems, and provides a cylindrical roller bearing welding strut retainer which improves the guiding of struts and hollow rollers, reduces the damage probability of the bearings due to the struts and the rollers and prolongs the service life of the bearings.
The technical scheme adopted by the invention is as follows:
The cylindrical roller bearing welding strut retainer comprises an annular retainer seat, an annular retainer cover, struts, wedge-shaped fixing rings and hollow rollers, wherein the hollow rollers are sleeved on the struts, the hollow rollers are arranged between an outer ring of a bearing and an inner ring of the bearing, and a plurality of strut insertion holes are formed in the annular retainer cover. The ring-shaped retainer seat is characterized in that a plurality of pillar fixing screw holes are respectively arranged on the ring-shaped retainer seat, and ring-shaped conical surfaces are arranged at the outer ports of the pillar fixing screw holes. The support is characterized in that one end of the support is provided with external threads, the diameter of each external thread is smaller than that of the support, conical surfaces are arranged at transition positions of the support and the external threads, the external threads are in threaded connection with support fixing screw holes on the annular retainer seat, and the conical surfaces are matched with the annular conical surfaces. The other end of the support column is provided with an assembly fixing head, the diameter of the assembly fixing head is smaller than that of the support column, the outer periphery of the assembly fixing head is provided with an inclined conical surface, and the assembly fixing head is inserted into a support column jack on the annular retainer cover. The wedge-shaped fixing ring is inserted into the strut jack from the outer side of the annular retainer cover, the wedge-shaped fixing ring is respectively and tightly matched with the inner wall of the strut jack and the inclined conical surface of the assembly fixing head, and a welding connection block is fixed at an orifice of the outer side of the strut jack.
Compared with the traditional structure, the invention greatly improves the guiding of the inner holes of the support posts and the rollers and reduces the damage probability of the bearing due to the support posts and the rollers. The roller is more stable in the transition process of the roller from the non-load area to the load area, and the vibration of the bearing is reduced.

Detailed Description
The cylindrical roller bearing welding strut retainer comprises an annular retainer seat 1, an annular retainer cover 2, struts 3, wedge-shaped fixing rings 4 and hollow rollers 5, wherein the hollow rollers 5 are sleeved on the struts 3, the hollow rollers 5 are arranged between a bearing outer ring 6 and a bearing inner ring 7, and a plurality of strut insertion holes 8 are formed in the annular retainer cover 2. The key point is that a plurality of pillar fixing screw holes 9 are respectively arranged on the annular retainer seat 1, and annular conical surfaces 10 are arranged at the outer ports of the pillar fixing screw holes 9. One end of the support column 3 is provided with an external thread 11, the diameter of the external thread 11 is smaller than that of the support column 3, a stepped shaft shape is formed, a conical surface 12 is arranged at the transition position of the support column 3 and the external thread 11, the external thread 11 is in threaded connection with a support column fixing screw hole 9 on the annular retainer seat 1, after the support column 3 is screwed down, the conical surface 12 is matched with the annular conical surface 10, and the perpendicularity of the support column 3 and the annular retainer seat 1 after the screw down is guaranteed. The other end of the support column 3 is provided with an assembly fixing head 13, the diameter of the assembly fixing head 13 is smaller than that of the support column 3, the outer periphery of the assembly fixing head 13 is provided with an inclined conical surface 14, the assembly fixing head 13 is inserted into the support column jack 8 on the annular retainer cover 2, and a wedge-shaped space is formed after the inclined conical surface 14 is matched with the support column jack 8. The wedge-shaped fixing ring 4 is inserted into the strut jack 8 from the outer side of the annular retainer cover 2, the wedge-shaped fixing ring 4 is respectively in close fit with the inner wall of the strut jack 8 and the inclined conical surface 14 of the assembly fixing head 13, the perpendicularity of the strut 3 can be further corrected at the moment, and a welding connection block 15 is fixed at an outer side orifice of the strut jack 8. Thereby ensuring guidance of the inner bore of the strut 3 and the hollow roller 5 during operation of the bearing. In addition, the inner diameter of the post insertion hole 8 of the annular retainer cover 2 and the inner diameter of the post fixing screw hole 9 of the annular retainer seat 1 are uniform in size, so that the annular retainer cover can be processed at one time, and concentricity is ensured. The installation needs to be matched and installed according to marks.
