Embodiment Construction

[0017] figure 1 A detail of a conventional support member 1 is shown with an outer ring 2, an inner ring 3 and balls 4 housed therebetween. exist figure 1 It is recognized that the running paths of the outer ring 2 and of the inner ring 3 each have a Gothic contour. exist figure 1 , arrows 5, 6 are drawn at two opposite locations where narrow manufacturing tolerances must be observed in order to prevent contact between the balls 4 and the gothic contour of the bearing ring .

[0018] In contrast, figure 2 A support member 7 is shown having an outer ring 8 with a gothic profile and an inner ring 9 with a continuous profile. Thus, the support member 7 comprises an outer ring 8, an inner ring 9 and balls 10 arranged therebetween. exist figure 2 In the position indicated by the arrow 11, the distance between the ball 10 and the inner ring 9 is the same as figure 1 The conventional support member 1 is larger. Undesired point contact between the inner ring 9 and the balls...

Abstract

A bearing component (7) comprising an outer raceway, an inner raceway and balls (10) accommodated therebetween; one raceway has an ogival profile while the other raceway has a spherical profile.

Description

technical field [0001] The invention relates to a bearing member having an outer rolling track and an inner rolling track, and balls accommodated between the outer rolling track and the inner rolling track. Background technique [0002] In the bearing components, different geometries are used for the rolling tracks. It is also known that, in ball screw drives, the ball raceway is produced not only on the spindle, but also on the ball screw nut with a Gothic profile. Similarly, in the case of axial ball bearings (four-point bearings), the inner and outer rings can also be provided with a Gothic profile. [0003] In the case of rolling tracks with a Gothic profile, undesired three-point contact can occur which adversely affects the rolling motion of the rolling bearing. [0004] On the other hand, it is common in which radial ball bearings are provided with an inner ring and an outer ring which have a continuous radius, ie have a spherical profile. Here, the inner and outer...
