Abstract
The invention relates to an anti-friction bearing (1) having a brake device, in particular a revolving joint, consisting of a bearing outer ring (2) and a bearing inner ring (3) between which anti-friction elements roll on associated raceways, wherein a braking effect by means of frictional engagement is achieved by pressing a displaceable brake element, which is connected to one of the bearing rings (3, 2) and has a brake lining (15), against a opposing surface (23), which is connected to the other bearing ring (2, 3). According to the invention, the opposing surface (23) is provided with a friction-increasing coating (24) which consists of a base material (25) and at least one incorporated additional material (26).
Claims12
An anti-friction bearing, comprising:
- a brake device, in particular rotary joint, having a bearing outer ring;
- and a bearing inner ring, between which rolling bodies roll on associated raceways, with a movable brake element which is connected to one of the bearing rings being pressed with a brake lining against a mating surface, which is connected to the other bearing ring, in order to obtain a braking action by means of frictional engagement,
- wherein the mating surface is provided with a friction-increasing coating which is composed of a basic material and at least one incorporated additive material.
