Abstract

PURPOSE:To reduce the number of manufacturing steps by a method wherein two curved surfaces having different center of curvatures are formed in the two areas with an axial central line being set therebetween, and they are split at a central part along their circumferential surfaces by themselves so as to make two outer members. CONSTITUTION:Two curved surfaces having a center of curvature at a point spaced apart by l/2 from a crossing point between the center line a and an axial line b of an annular member are formed at the inner surface of the integrally- formed annular member and at the two areas with an axial central line (a) being set therebetween and the annular member is split at its central part and along its circumferential surface by itself so as to make two outer members 3b and 3c. The two outer members 3b and 3c made in this way are assembled in an inner member 3a having a convex spherical surface with a space l being axially set.

Description

DETAILED DESCRIPTION OF THE INVENTION Complaint #4IIi is directed against the manufacturing method of a spherical surface shaft.

It requires alignment, and the radial noodle and ceramic direction are effective, and when it is used in a dynamic or low continuous tat rotation, it is difficult to increase the sma due to wear during use. Places that can be adjusted, i.e. civil engineering machinery, l! Construction machinery and other general whaling industry machinery, such as one-wheel loaders and motor grader artekierate bin bearings Wt#II, have inner members with convex spherical surfaces and bushes that separate the inner members. It is known to use a spherical pan-shaped bearing consisting of a large outer member. However, the conventional J-piece spherical bearings can be assembled by machining the inner and outer parts of the J-piece spherical bearing separately, but this increases the number of processing steps. (On the other hand, bearings are mass-produced products.)
, the image is reduced to 1, and the reduction is large to JllF[* (contributes to rounding, reduction in processing man-hours).

ζ0*Meiji, from the above point, for the inner member of a spherical sliding bearing with a convex spherical surface, which is a sealed round product, a J0** member is manufactured as follows. jll also /ri0

From the intersection of 40, and the outer member is made of a W structure, with the outer member extending at a distance and being attached to the inner member.

Hereinafter, the ζO invention omri will be clarified according to the prefecture/figures showing specific examples and the 11kJ diagram.

In the drawing, the 11'Fi positioning part (1a) is placed on the left side of the 11' positioning part (1a), the 11'Fi positioning part (1a) is placed on the left side of the 11' positioning part (1a), and the positioning shoulder part (2) is placed on the side of the second position.

It is a mounting member. Then, a gap of more than Q~da op occurs, and the gap is adjusted by moving the mounting member +110 in the axial direction. In this case, the clearance O# is adjusted by inserting a shim (-) between the external force member 1litil+ and the mounting member 111.

In this invention, in order to reduce the processing cost of the J-piece spherical special bearing, the outer member (easy b) (30) is used as a processed member such as the annular member 04#! A piece of K11m1 is symmetrical with natural alignment in the circumferential direction, and as shown in mS1 J factor, it is integrally machined and has a hollow line (toward the boundary) facing inward and in one direction of the nine-slab-shaped member. 2') In the 0 area, spaced 17 degrees apart from the intersection of the central axis of the Joki (- and the axis of the annular member!

The main W! The outer member of the spherical slide bearing, which is a component, can be manufactured at a low cost, and the bearing gap during use can be easily filled by inserting shims into the fitting member and the mounting member, and it has extremely practical value. .
