Radial bearing of eccentric outer ring and multi-row radial bearing with eccentric outer ring divided by the number of rows

摘要

Radial bearings used in machine tool spindle and the like have internal clearance in the bearing itself, and the shaft is shaking when rotated.;In order to solve this problem, the rolling surface of the bearing outer ring is machined eccentrically by the clearance of the bearing, the grooved groove 3 is formed on the side of the first thick part 2 of the outer ring and the pin 5 is formed on the opposite side, So that a plurality of bearings can be controlled and assembled at an arbitrary angle.;In addition, the outer ring of the outer bearing of the bearing is eccentrically formed by the clearance of the bearing so that the outer ring is formed in each direction.;It is used for machine tool spindle which requires shaking of shaft, precision, rigidity and so on.
