摘要： A half bearing constituting a cylindrical plain bearing for supporting a shaft for rotation when two of the half bearings are combined together. The half bearing has two circumferential ends each of which has a plurality of circumferential grooves without formation of any crush relief surface. The grooves extend substantially over an overall circumferential dimension of the half bearing and include portions located at both circumferential ends of the half bearing respectively. Each portion has a larger axially sectional area than the grooves formed in a portion of the half bearing mainly subjected to load during rotation of the shaft.

摘要： PROBLEM TO BE SOLVED: To easily machine a plurality of inclined faces having different angles to be formed at both sides in the axial direction of the inner periphery face of a bearing alloy. SOLUTION: A machining holder 18 has a groove 20 on the inner periphery face extending to the peripheral direction and is formed with the groove 20 stepped at both sides in the cross direction, and a half-split bearing 11 is stored in the machining holder 18. The half-split bearing 11 is thrust at both ends in the peripheral direction by a thrusting member 24, whereupon the half-split bearing 11 is elastically deformed to be fitted into the groove 20 and then deformed in a polygonal line with both sides in the cross direction hitting corners 22, 23 of the stepped portions. In this state, the half-split bearing 11 is machined at both sides in the axial direction along one cylindrical face by a broach 19. Thus, two inclined faces having different angles are continuously formed at both sides in the axial direction of the bearing alloy 13 of the half- split bearing 11.

摘要： PURPOSE:To simultaneously attain reduction of frictional resistance and a tapping sound by setting height from a virtual reference line to a mountain-shaped vertex and height from a valley-shaped recessed bottom part to the mountain- shaped vertex to within a range enveloped by a straight line represented by particular four general formulas. CONSTITUTION:In a total region in the axial direction of a slide contact surface 1A formed with a helical groove 1B, in a position where a total sectional area of each mountain part 1a is obtained equal to a total sectional area of a space part formed of each valley part 1b, a virtual reference line L parallel to the axial center is obtained by crossing with each mountain part 1a. Height from this virtual reference line L to a vertex 1a' of each mountain part 1a is assumed as DELTAc, and height from a bottom part 1b' of the valley part 1b to the vertex 1a' of the mountain part 1a is assumed as (h). In a linear graph taking the height (h) in a horizontal axis and the height DELTAc in a vertical axis, the height DELTAc and (h) is set to within a range enveloped by a straight line represented by formulas I to IV (dimensional unit of h and DELTAc is mum). In this way, reducing a slide drag and a hammering sound can be simultaneously attained.
