Embodiment Construction

[0025] Hereinafter, an embodiment as an example of the present invention will be described with reference to the drawings. The present invention is not limited to this embodiment. In addition, the drawings are schematic, and the dimensional relationship of each part may differ from the actual one.

[0026] Such as figure 1 As shown, the inner wheel arc surface measuring device 1 has a main body 2 formed in a substantially L-shaped front shape and two dial gauges (measuring instruments) 3, 4. In this embodiment, for image 3 The inner ring 61 of the shown self-aligning roller bearing 60 is described as an example of a measurement object.

[0027] The main body 2 is composed of a reference part 21 having a predetermined length and a measurement part 22 extending vertically from one end part of the reference part 21 in the longitudinal direction. Through-holes 22a, 22b extending parallel to the longitudinal direction of the reference part 21 are formed at two different positi...

Abstract

A manufacturing method of an automatic self-aligning roller bearing and a measuring device for an inner ring arc surface. As a method of manufacturing the inner ring constituting the self-aligning roller bearing, compared with the methods described in Patent Documents 1 and 2, it is possible to more easily perform design values ​​for the shape of the arcuate surface forming the raceway at the machining site. The process method of confirming the deviation. Two points ( The dimensional difference (d) between A and B) along the radial direction of the inner ring (61) is measured. By comparing the dimensional difference (d) measured in the measurement process with the design value (d0) calculated from the formula (1), the deviation from the design value of the shape of the arcuate surface is confirmed. In formula (1), R0 is the design value of the radius of curvature of the arc (E) surface, h0 is the design value of the distance (h) from the center of curvature (C) of the arc E surface to the axial end surface (61c), .

Description

technical field [0001] The present invention relates to a method for manufacturing an automatic self-aligning roller bearing and a device for measuring the inner ring arc surface of the automatic self-aligning roller bearing used in the method. The process of confirming the deviation of the design value of the arc surface of the inner ring is the inner ring that constitutes the self-aligning roller bearing. Background technique [0002] For example image 3 As shown, the self-aligning roller bearing is a self-aligning bearing with two rows of rollers 63 installed between the inner wheel 61 and the outer wheel 62 . The outer peripheral surface of the inner ring 61 is formed with two raceway surfaces 61a in the shape of concave arcuate surfaces. The inner peripheral surface of the outer ring 62 is a concave spherical raceway surface 62a. image 3 The self-aligning roller bearing 60 has a guide wheel 65 and a cage 64 in the shape of a "corner" extending from the axial center t...
