Calculation of the series bearing of tone

series 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. 320 & 329 series bearing 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 Slewing Bearing  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. series bearing is complex, precision bearings many factors affect the radial clearance. Only by 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.
