Locating correction method for improving coaxiality of bonded dual-pedal bearing inner rings

Abstract

The invention provides a locating correction method for improving coaxiality of bonded dual-pedal bearing inner rings. The locating correction method is as follows: three inner rings with the same type as the A-pedal inner ring (1) and the B-pedal inner ring (2) are taken as standard rings (8), wherein, the end face of each standard ring is marked with an end A and an end B, the end A is corresponding to the A-pedal inner ring, and the end B is corresponding to the B-pedal inner ring; one of the standard rings is sheathed on a fixed shaft of a working platform and the end A is contacted with the working platform, the other two standard rings (8) are respectively sheathed on two stressed shafts of the working platform and the A ends are also contacted with the working platform, wherein, the fixed shaft and the two stressed shafts are distributed at an angle of 120 degrees; the bonded A-pedal inner ring and B-pedal inner ring are placed in the middle of the three standard rings, wherein, the A-pedal inner ring is also contacted with the working platform; and at such time, the force is applied synchronously to the two stressed shafts, and then the two stressed shafts are matched withthe fixed shaft to carry out locating correction on coaxiality errors generated when the A-pedal inner ring (1) is bonded with the B-pedal inner ring (2). The locating correction method in the invention is simple and practical.

Description

technical field [0001] The invention belongs to the technical field of bearing processing, and in particular relates to a positioning correction method for improving the coaxiality of the inner ring of a two-lobed bearing after bonding. Background technique [0002] The inner ring raceway of some contact ball bearings is in three-point contact or four-point contact during operation. In order to ensure the raceway processing of the contact point, the inner ring is designed as two petals during design, that is, two A petals with the same structure The inner ring and the inner ring of the B lobe are bonded together according to the direction of the raceway to form an inner ring. The inner ring of the A lobe and the inner ring of the B lobe are processed separately during rough machining, but the inner ring of the A lobe is usually processed during fine grinding. The inner ring of the inner ring of the A lobe and the inner ring of the B lobe are bonded together to ensure the con...

AI Technical Summary

Problems solved by technology

[0003] The current method to ensure the coaxiality is to indirectly eliminate the positioning error by increasing the fine grinding allowance of the inner ring of the two-lobed bearing, but the defects of this method are low production efficiency, high processing cost and high scrap rate
