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...

Embodiment Construction

[0030] figure 1 In three-dimensional view illustrating a bearing housing having two longitudinal sides 9a, 9b of 1; 1a, wherein, in each longitudinal side 9a, 9b are arranged toward the direction of the raceway for the rolling bodies 2a directed stop side 7a, 7b. figure 2 It illustrates in cross-section according to figure 1 The bearing housing 1; amplified fragment area in the flange 1a, 7b. Bearing housing 1; 1a to harden the hardening method. Bearing housing 1; 1a has a body 5 made of steel (see figure 2 ), And having a raceway for rolling elements 2 on the first side 2a. A second body 5 facing away from the side of the first side 2 has a coating 3 made of a coating material 6, it is set up as a coating material, during the execution of hardening method for forming the carbon in the region of the second side 3 5 toward the direction of the main body of the diffusion barrier. According to figure 2 7b is a section through the wall, in enlarged view, on the side of the first laye...
