Embodiment Construction

[0018] exist figure 1 The bearing 1 shown in a side sectional view in FIG. 1 is a component of the swivel joint by means of which the roof support of the medical device is supported.

[0019] The rotary connection with self-locking bearing 1 comprises an inner ring 2 , an outer ring 3 and an intermediate ring 4 arranged radially between the inner ring 2 and the outer ring 3 .

[0020] A first sliding pair 5 is formed between the inner ring 2 and the outer ring 3 and a second sliding pair 6 is formed between the intermediate ring 4 and the outer ring 3 . The bearing 1 is therefore designed as a sliding bearing, each sliding pair 5 , 6 having a sliding surface coated with a lubricating coating.

[0021] The outer ring 3 has through-openings 7 in order to connect the outer ring 3 to another component, for example a carrying arm of a roof support of a medical device. Similarly, the inner ring 2 has a blind thread 8 in order to connect the inner ring 2 with another part of the ro...

Abstract

A rotary connection with a self-locking bearing (1), in particular for supporting a roof support, said rotary connection having an inner ring (2) and at least one outer ring (3), wherein the bearing ( 1) Designed as a sliding bearing and having an intermediate ring (4) arranged radially between at least one inner ring (2) and at least one outer ring (3), each ring having at least one annular shape that is not accessible from the outside A sliding surface, and a first sliding pair (5) is provided between at least one inner ring (2) and an outer ring (3), and a first sliding pair (5) is provided between the intermediate ring (4) and at least one outer ring (3). There is a second sliding pair (6), wherein the sliding surface of the sliding pair (5, 6) is covered with a lubricating coating.

Description

technical field [0001] The invention relates to a rotary connection with a self-locking bearing, in particular for supporting a roof support, the rotary connection having an inner ring and at least one outer ring. Background technique [0002] Rotary connections with self-locking bearings are required in various applications. Examples of this are, for example, roof supports for medical devices, painting robots, bicycle balancers, main supports for heliostats and other applications. [0003] In all applications, an adjusting and operating torque that is as constant as possible over the life of the self-locking bearing and the rotary connection is required. Common rotary connections with self-locking bearings consist to one rolling bearing and separate braking or friction elements in order to produce the desired self-locking. The rotary connection with self-locking bearings based on rolling bearings can be designed to be low-maintenance or maintenance-required. In the first...
