Jiaxing bearings of rolling bearing clearance adjustment and preloaded

There is rotational, have HRB bearing ( ) Jiaxing bearing group sales co. , LTD. ( The company) Is bearing group co. , LTD. Established in jiaxing spot sales window, specializing in HRB brand bearings, facing the whole country, the existing stock 50 million yuan, covers the whole bearing, have very strong spot supply, is the group's retail sales center. Rolling bearing assembly is fitter assembly and repair work often have to do an operation, and the adjustment of the rolling bearing clearance and preload is an important tache in rolling bearing assembly. Accurately grasp the clearance adjustment and pre-tightening technology concept, and in the assembly work correctly using this technique, is the assurance of quality of bearing assembly work. Rolling bearing clearance is to point to in a ring under the condition of fixed, another ring along the radial or axial maximum activity, so the clearance is divided into radial clearance and axial clearance. Rolling bearing assembly, the clearance cannot too big, also not too small. Clearance is too large, will cause the load to reduce the number of roller at the same time, make single roller load increases, thus reducing the rotating precision of bearing, reduce the service life; Clearance is too small, can make the friction force increases, the heat generated by the increased, aggravate wear, also can reduce the service life of bearing. Therefore, when a lot of bearing in the assembly to strictly control and adjust the clearance. When is preloaded bearing assembly, for bearing inner ring and outer ring an axial force, to remove the bearing clearance, and make contact with the inner and outer ring roller early deformations. Preloaded can improve bearing stiffness and rotation accuracy at work. For load bearing is larger, higher bearing rotating accuracy requirement is mostly in the absence of clearance there is even a small amount of work under the interference of the state, in this case you need in the assembly of bearing preload.
