Example Embodiment

[0031] The tolerance ring according to the prior art of Fig. 1(a) has been described above.

[0032] The difference between the tolerance ring 1 in Fig. 1(b) and (c) and the tolerance ring 1 in Fig. 1(a) lies in the material recesses 4, which are machined in the tolerance ring 1 in a targeted manner to reduce these Spring rigidity of the tolerance ring.

[0033] In the tolerance ring 1 of Fig. 1(b), a number of holes 4 are processed in the connection device of the tolerance ring 1 of Fig. 1(a) for the hemispherical structure between the crimping 2 and the traction belts 51, 52.

[0034] In the tolerance ring 1 of Fig. 1(c), instead of the cylindrical crimp, there are provided angular bulges 2. Between these bulges, the material recesses 4 or the traction belts 51, 52 are alternately arranged or connected. Undeformed area 501.

[0035] It has been proved that the tolerance ring 1 shown here exemplarily in Figs. 1(b) and (c) allows the tolerance ring 1 to be manufactured with larger to...

Abstract

The present invention relates to a shaft-hub connection device, in particular an overload protection device, comprising a shaft, a hub and a tolerance ring that is interposed between the shaft and the hub, wherein either the shaft or the hub is surface-treated, in particular coarse-ground, milled, sandblasted and/or peened. The present invention further relates to an adjusting drive for a vehicle with the hub-shaft connection device.

Description

technical field [0001] The invention relates to a shaft-hub connection, in particular to an overload protection device, with an inner component, an outer component and a tolerance ring, the tolerance ring being arranged in the region of the tolerance ring between the inner component and the outer component. The invention also relates to an adjusting drive for a vehicle with such an axle-hub connection. Background technique [0002] Tolerance rings are commonly used for friction fit shaft-hub connections. Because large manufacturing tolerances and shaft center differences between the shaft and hub can be compensated by means of the tolerance ring. The tolerance ring is therefore also suitable for equalizing the different coefficients of thermal expansion of the shaft and hub. [0003] Torque can be transmitted from the shaft to the hub and vice versa through the friction fit connection formed with the tolerance ring. In this case, the connecting device can be used in a tar...
