IKO plane bearing clearance adjustment and preloaded

Plane bearing assembly is the basic operation of benchwork assembly and repair work, and the adjustment of the clearance and preload is an important link in IKO bearing assembly work. Accurately grasp the clearance adjustment and pre-tightening technology concept, and in the assembly work correctly using this technique, is the assurance of plane bearing assembly work quality. Plane bearing clearance is fixed in a ring, another ring along the radial or axial made the biggest activity, so the clearance is divided into radial clearance and axial clearance. IKO bearing assembly, clearance cannot too big, also not too small. Clearance is too large, will cause the load at the same time reduce the number of roller, a single roller load increase, thereby reducing IKO bearing rotating accuracy, 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 plane bearing assembly to strictly control and adjust the clearance. Preload is when plane bearing assembly, for inner ring and outer ring an axial force, to eliminate IKO bearing clearance, and make contact with the inner and outer ring roller in the early deformations. Preloaded can improve bearing in the working status of the stiffness and rotation accuracy and load 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. Adjustment of clearance and preload is usually by inner ring external circle for appropriate axial relative displacement method. It is not hard to see from the above technology concept, through to the rolling bearing clearance adjustment, can improve the bearing capacity of plane bearing and rotating accuracy, improve the service life of bearing. But at the same time can make the bearing friction intensified, calorific value increases, so adjust the clearance or preload must guarantee good lubrication and cooling. If improper or poor lubrication, you will in turn exacerbated IKO bearing wear, reduce the service life. Correctly and be adjusted and preloaded plane bearing clearance, but also pay attention to the following questions.
