Bearing shell for half shell bearing, half shell bearing and use thereof

Abstract

The invention relates to a bearing shell (1; 1a, 1b) for a half-shell bearing (100) having at least one raceway (2a) for rolling elements (4) on a first side (2), wherein , the bearing shell (1; 1a, 1b) is hardened by a hardening method, wherein the bearing shell (1; 1a, 1b) has a main body (5) made of steel, and wherein the main body (5) is on the side facing away from the first The second side (3) of (2) has on the second side (3) at least one coating (6) consisting of a coating material, which is set up so that, during the hardening method, in the region of the second side (3) is formed against Diffusion barrier of carbon towards the body (5). Furthermore, the invention relates to a method for producing such a bearing shell (1; 1a, 1b), a half-shell bearing (100) formed from a bearing shell (1; 1a, 1b) and its use.

Description

Technical field [0001] The present invention relates to a bearing housing for a half-shell bearing having at least one raceway for the rolling elements on the first side. The invention further relates to a method for producing such a bearing housing, the bearing half shell and the use thereof. Background technique [0002] DE 10 2010 006 262 A1 describes a half-shell according to the generic disk brake for a motor vehicle bearing. In DE 10 2010 006 262 A1 of figure 1 This is shown in a typical half-shell bearing load conditions. [0003] Typically, as made of a strip-shaped cold deformed steel base material for the bearing half shells in particular for utility vehicle disc brake on the housing half-shell or bearing needle bearing, which is usually a surface-hardened . Based on a high, almost static load occurring in the disc brake, defining generally selected high surface hardening depth. [0004] The bearing housing is usually formed with lateral flanges, which by rolling the st...

AI Technical Summary

Problems solved by technology

Thorough hardening leads to a marked reduction in the elasticity of the ribs, which can lead to rib breakage under axial loads

Furthermore, the comparatively high case-hardening depth in the region of the rib in relation to the material thickness leads to a reduction in the elasticity of the hooks and the anti-twist attachments arranged on the bearing housing, which must in part be achieved by an additional inductive tempering process to partially compensate

This aspect leads to increased costs due to the necessary additional processes
