Calculation of the needle roller bearing radial clearance of tone

Self-angular contact bearing‍ should ensure the outer spherical raceway and 

roller and raceway ask radial clearance at the contact line in the 

direction of the supporting, the radial clearance. Effect of self-aligning 

roller bearing radial clearance C, the main factors are: outer ring 

spherical Lang was D.. Inner ring diameter

Distance of two roller and roller contact by diagonal ask. The maximum 

diameter of D and the spherical roller

What is different. Spherical roller bearings supporting the identification 

process, the outer ring spherical raceway diameter deviation and the inner 

ring two most road diagonal distance deviation measurement and centripetal 

bearing the general differences. Measurement of packet and Zhu spherical 

raceway diameter deviation is generally performed by D924, bore dial 

indicator instrument; measurement packets in which two rolling deviation 

road diagonal distance is quite difficult. There are two methods used at 

present: don't choose an approximate diagonal distance measurement method, 

another is the method of measuring diameter of roll.

Structure self-aligning roller bearing is complex, many factors affect the 

radial clearance. Only by thrust roller bearing‍ grouping calculation matching is not guaranteed 

to pass the radial internal clearance of the bearing. This kind of bearing 

must be clearance in the matching test for the feast. Matching efficiency 

can reach the higher matching ginseng powder - revised. Aligning roller on 

the radial travel clothes measuring bearing commonly used in removing. At 

present, most manufacturers use 12 measurement device and plug K by way of.‍
