Problems solved by technology

(3) The inclination angle of the rib has a great influence on the axial bearing capacity
However, this measurement method has certain defects: (1), it can only measure the height range of the rib, and cannot quantitatively measure the height of the rib
(2) In the complete set of bearings, the height of the ribs of the inner and outer rings is quite different. After the bearing is installed and used, the rollers are easy to tilt, which affects the rotation flexibility of the bearing and the life of the bearing.
(3) The template is easy to wear and tear, causing the height of the rib to be out of tolerance

Abstract

This invention discloses a method for quantitative measuring the inclined stop edge height of cylindrical roller bearing ring, which contains selecting standard measuring steel ball, calculating the standard block size used for measuring stop edge, comparing said standard block with the height of stop edge to make quantitative measurement for cylindrical roller bearing ring.

Description

Technical field [0001] The invention belongs to a bearing oblique rib measurement technology, and mainly relates to a method for quantitatively measuring the oblique rib height of an EC-type cylindrical roller bearing ring. Background technique [0002] Cylindrical roller bearings are widely used in various large, medium and small automobiles, road rollers, rail vehicles, machine tool spindles, internal combustion engines, conveyor drives, gyratory crushers, gear drives, rolling mills, and lifting and transportation machinery. The general structure of cylindrical roller bearings is that one ring has double ribs, the other ring has no ribs or has one rib, and the inner and outer rings are separable. Cylindrical roller bearings with ribs on both rings can withstand certain axial loads. In the EC-type design to improve the axial load capacity of cylindrical roller bearings, through the study of rib lubrication theory, the original straight ribs of cylindrical roller rings are ...
