Know about the assembly of the rolling bearing in the rolling bearing manufacturers

In the 21st century, all kinds of industrial technology in China has become increasingly mature, a kind of based on experience and intuition, by trial and error as the basic method of the technology - - - - - - - Traditional bearing ring forging process also began to welcome the baptism of the new era of fusion of modern technology, continuous improvement of process. About the research content of bearing ring forging process, rolling bearing manufacturers not only to understand the status quo of bearing forging process study, the process of bearing forging process itself, also involves bearing ring ring forming process is studied. Rolling bearing manufacturers of special pressure should be used when the rolling bearing assembly, assembly, it is forbidden to adopt the method of direct hit suit when bearing strength size, direction, location should be appropriate. ( 1) Before rolling bearing assembly, bearing a may not have any sludge quality. ( 2) Rolling bearing assembly should be in with a surface coating a layer of lubrication, no one end of the model should be took a bearing, which rely on shoulder. ( 3) Special pressure should be used when the rolling bearing assembly, assembly, it is forbidden to adopt the method of direct hit suit when bearing strength size, direction, location should be appropriate, should not make the protection or rolling element bearing, should be symmetrical force uniform, guarantee the end face and the vertical axis. ( 4) Bearing inner ring end face generally should be close to the shoulder ( Shaft card) , after the bearing outer ring assembly, the location of end bearing cover and gasket or outer ring should be uniform. ( 5) After rolling bearing factory assembled, relative motion of the rotation should be flexible, lightweight, if there is a card lag phenomenon, should check analysis the cause of the problem and corresponding processing. ( 6) Rolling bearing assembly process, if discover hole or shaft with too loose, check the tolerance; Too tight when no forcible savage assembly, should check the analysis of the cause of the problem and corresponding processing. ( 7) Single row circular cone roller bearings, thrust angular contact bearings, two-way thrust ball bearing axial clearance when it is assembled in accordance with drawings and technical requirements. ( 8) To use grease bearings and with the combination of the surface of the assembly should be injected after the right amount of grease. For bearing operating temperature does not exceed 65 ℃, can press GB491 - The calcium base grease the mid-december - 65 5 grease; For bearing operating temperature higher than 65 ℃, can press GB492 - The calcium base grease the zinc - 77 2、锌- 3 grease. ( 9) Plain bearing temperature rise during normal work should not be more than 35 ℃, the work of the high temperature should not exceed 70 ℃.
