Play-free plain bearing and use of a play compensation element to create a play-free plain bearing

Abstract

The present invention relates to a play-free plain bearing with a first part 1 and a second part 2, wherein one of the two parts 1, 2 is stationary and the other part 2, 1 moves relative to it, wherein the first part 1 has a base element 3 and a first sliding surface 4 and the second part 2 has a second sliding surface 5, wherein the first sliding surface 4 and the second sliding surface 5 are in contact with each other, wherein a play compensation element 6 comprising a compressed viscoelastic foam 6 is arranged between the base element 3 and the first sliding surface 4.The invention also relates to a use of a play compensation element 6 between a first part 1 and a second part 2, wherein one of the two parts 1, 2 is fixed and the other part 2, 1 moves, to produce a play-free sliding bearing, wherein the play compensation element 6 comprises a compressed viscoelastic foam 6, in particular is a compressed viscoelastic foam 6.

[2] Play-free sliding bearing according to claim 1, wherein the first sliding surface (4) is formed on a flexible film (11), which is designed in particular as a laminated foam part with a wear-free sliding layer, which is connected to the base element (3) in a connecting region. [3] Play-free plain bearing according to claim 1, wherein the first sliding surface (4) is formed on a rigid sliding body (7), in particular a plate made of a material with low frictional resistance relative to the contact surface, such as polyamide, Teflon® or Iglidur®, which is connected via a slider housing (8) fastened to the base element (3). [4] Play-free plain bearing according to claim 3, wherein the slider housing (8) comprises a bearing plate (13) with a recess (14) in which the play compensation element (6) is arranged. [5] Play-free plain bearing according to one of claims 2 to 4, wherein the connection of the flexible film (11) to the base element (3) in the connection area and / or the connection of the slider housing (8) to the base element (3) is carried out by means of gluing, screwing, riveting or welding. [6] Play-free plain bearing according to claim 1, wherein the base element (3) comprises a bearing element (15) in which a sliding body (7) is arranged, on which the first sliding surface (4) is formed, and the second part (2) comprises a U-profile (25), wherein the second sliding surface (5) is formed on one of the two free legs of the U-profile (25). [7] Play-free plain bearing according to claim 6, wherein the base element (3) is mounted on a roller journal (26) of the cross tube (19) and a roller (18) is rotatably fastened on the roller journal (26), which roller is in contact with the other of the two free legs of the U-profile (25) with its running surface. [8] Play-free plain bearing according to claim 1, wherein the base element (3) has a bearing element (15) in which an additional roller holder (22) is arranged, in which an additional roller (23) is mounted, the running surface of which forms the first sliding surface (4), and the second part (2) has a U-profile (25), wherein the second sliding surface (5) is formed on one of the two free legs of the U-profile (25), wherein the play compensation element (6) is arranged between the base element (3) and the additional roller holder (22). [9] Play-free plain bearing between a contact surface of a roller (18), which is rotatably mounted on a roller journal (26), and a guide rail, which is designed in particular as a U-profile (25), by means of a play compensation element (6) arranged between the end face (20) of the roller journal (26) and the roller (18), wherein the play compensation element (6) comprises a compressed viscoelastic foam (6). [10] Play-free plain bearing between an end face (20) of a roller journal (26), on which a roller (18) is rotatably mounted, and a sliding region of a guide rail, which is designed in particular as a U-profile (25), wherein the end face (20) is pressed by means of a play compensation element (6) arranged between the end face (20) of the roller journal (26) and the guide rail, wherein the play compensation element (6) comprises a compressed viscoelastic foam (6). [11] Play-free plain bearing according to claim 9 or 10, wherein a metal disc (17) is arranged between the end face (20) of the roller journal (26) and the roller (18) or the sliding area of the guide rail. [12] Use of a play compensation element (6) between a first part (1) and a second part (2), wherein one of the two parts (1, 2) is stationary and the other part (2, 1) moves, to produce a play-free sliding bearing, wherein the play compensation element (6) comprises a compressed viscoelastic foam (6), in particular is a compressed viscoelastic foam (6).
