Problems solved by technology

[0006] Deep-groove thrust ball bearings acting on both sides usually have several individual parts to be mounted, which have to be clamped or fixed when mounted in the bearing support point, which on the one hand makes their installation very expensive

Embodiment Construction

[0044] Figures 1 to 4 Shown are deep groove thrust ball bearings or radial thrust ball bearings acting on both sides, which each have two inner rolling grooves 10, 11, Two outer grooves 12 , 13 and two rows 4 , 5 of bearing balls 4 a , 5 a arranged circumferentially in inner grooves 10 , 11 and outer grooves 12 , 13 . Here, at least one of the outer grooves 12 , 13 is machined into the inner axial side of the outer (axial) running disk 2 , 3 .

[0045] Figure 1 to Figure 4 It is shown here that the bearing also has a sleeve 6 formed axially on both sides with radial edges 6 a , 6 b , in which sleeve an elastic element 7 in the form of a plastic ring made of an elastomer material is inserted. In this case, the sleeve 6 is designed in particular such that it holds all parts 1 , 2 , 3 , 4 a , 5 a , 7 of the bearing and can be pressed in with its outer diameter or pressed in with its inner diameter.

[0046] Figure 1 to Figure 4 The illustration shows that the running disks...

Abstract

The invention relates to a deep groove thrust ball bearing or a radial-thrust ball bearing acting on two sides. The deep groove thrust ball bearing or the radial-thrust ball bearing comprises two internal slot rollings (10, 11), two external slot rollings (12, 13), and two rows of bearing balls (4a,5a) which are arranged in the internal slot rollings (10, 11) and the external slot rollings (12, 13) in a surrounding manner. The internal slot rollings (10, 11) are processed on two axial sides of an internal operating disk (1). At least one of the two external slot rollings (12, 13) is processed in an internal axial side of external operating disks (2,3). In order to install the bearing in a simple method without gaps, the bearing also comprises a sleeve (6) which is provided with radial edges (6a,6b) on two sides along an axial direction. An elastic component (7) is inserted in the sleeve (6). The operating disks (1,2,3) are surrounded by the radial edges (6a,6b) of the sleeve. In addition, the invention also relates to a driving system equipped with the bearing.

Description

technical field [0001] The invention relates to a deep groove thrust ball bearing or radial thrust ball bearing acting on both sides and a drive system for actuating functional elements in a motor vehicle. Background technique [0002] Deep groove thrust ball bearings and double row radial thrust ball bearings acting on both sides can be used in applications with predominantly axial traction or pressure loads. [0003] For example, a pressure bearing with two or more ball rows is described in the printed document DE 402 575 . [0004] Printed document DE 20 2005 020 084 U1 describes the use of a deep-groove thrust ball bearing acting on both sides in a drive system for motor-driven operation of a motor vehicle rear lid. [0005] Printed document DE 20 2005 016 953 U1 likewise describes a drive system for the motor-driven operation of the rear lid of a motor vehicle, but instead of deep-groove thrust ball bearings acting on both sides, this drive system has bearing blocks. ...
