Abstract

The invention relates to a gear assembly (12) comprising a fixed gear (13) having a first radial toothing (16) and an idler (14) having a second radial toothing (17), the first radial toothing (16) being disposed at least approximately at the same radial height as the second radial toothing (17), and the fixed gear (13) further comprises a first axial end face (18) and the idler (14) comprises a second axial end face (19), and the fixed gear (13) is connected to the idler (14) by means of at least one elastic connecting element (21), for which purpose the elastic connecting element (21) is connected on the one hand to the first axial end face (18) of the fixed gear (13) and on the other hand to the second axial end face (19) of the idler (14).

Abstract

The invention relates to a device (4) for positioning meshing teeth (3, 8, 9) of a gear drive without any play, comprising a gear assembly (5), which gear assembly (5) comprises a main gear (6) having first teeth (8) and a gear (7) that is rotatable relative thereto in the circumferential direction having second teeth (9), and the main gear (6) comprises a hub part (10) on which the rotatable gear (7) is disposed, and a tolerance compensating element (12) comprising a shaft part (13) and a compensating part (14) is disposed radially underneath the main gear (6), and the compensating part (14) is connected to the shaft part (13) and to the hub part (10) of the main gear (6) so that the main gear (6) is connected exclusively via the compensating part (14) to the shaft part (13), and the compensating part (14) is made at least partially from a rubber elastic material.

Abstract

The invention relates to a gear (1) comprising a first, radially inner ring element (2), a second, radially outer ring element (3) and a connecting element (4), wherein the second, radially outer ring element (2) comprises a toothing (10), wherein the connecting element (3) is arranged in radial direction between the first, radially inner ring element (2) and the second, radially outer ring element (3) and is connected to the first, radially inner ring element (2) and the second, radially outer ring element (3), and wherein the connecting element (4) is made at least partly from a rubber-elastic material. In this case edges (11, 12) of the first, radially inner ring element (2) in the connecting area between the first, radially inner ring element (2) and the connecting element (4) and edges (16, 17) in the connecting area between the second, radially outer ring element (3) and the connecting element (4) are provided with a rounding (21 to 24).
