Processing method of tilted assembly angle bearing

Abstract

The invention relates to a processing method of a tilted assembly angle bearing, which is designed aiming at the problem of lower assembly efficiency of a motor shaft and a bearing seat due to non-ideal surface shape of a chamfer angle of the traditional like product. The processing method of the tilted assembly angle bearing is characterized by comprising the following steps of: processing tilted assembly angles on an inner ring and an outer ring of the bearing, wherein the surface shapes of the tilted assembly angles are cut into angles of 12-15 degrees along an X-axis direction of an inner hole of the inner ring or the outer cylindrical surface of the outer ring and cut into angles of 30-40 degrees along a Y-axis direction of the end surface of the inner ring or the end surface of the outer ring; enabling two cutting sides formed by the cutting to be smoothly transitional through an arc, wherein the radius of the arc is R=0.4-0.6 mm; then carrying out heat treatment on the inner ring and the outer ring after the inner ring and the outer ring are qualified through checkout; setting the X-axis as the axial direction of the bearing, and placing the Y-axis on a plane in which the end surface of the inner ring and the end surface of the outer ring are located. The invention achieves the requirements for the bearing precision of a high-grade motor, enhances the installation efficiency of the bearing and has higher popularization and application value.

Description

technical field [0001] The invention relates to a bearing, in particular to a processing method of an angular bearing with inclined assembly. Background technique [0002] At present, the national standard GB / T274-2000 stipulates the maximum and minimum values ​​of the chamfer size for rolling bearing assembly, but the exact shape of the chamfer surface is not pre-specified, but it is stipulated that its contour in the axial plane should not exceed the bearing end face 7 Arc 6 tangent to the inner hole of the bearing inner ring or the outer cylindrical surface 8 of the bearing outer ring (see appendix image 3 ). [0003] In production, all manufacturers basically produce rolling bearings according to the above standards. Because the shape of the chamfered surface is not constant, the arc is large and small. Therefore, after the bearings with such assembled chamfers are delivered to customers in the high-end motor market, the customers often have the following problems in u...
