Abstract

In a component for connecting a shaft to a clamping holder that can receive a rotor, the clamping holder is able to be inserted into a cup-shaped housing and is able to be fixed there by fasteners. On the housing base of the housing is a connector for connecting the housing to the shaft in a torque-proof manner. The fasteners are arranged with their base surface on the outer lateral surface of the housing, and can be brought into engagement with the clamping holder by bores present in the housing. The fasteners have at least one recess in the base surface, such that they rest with their base surface on the outer lateral surface only in some regions.

Claims (11)

1 . A component for connecting a shaft to a clamping holder that can receive a rotor, the component having a cup-shaped, thin-walled housing into which the clamping holder can be inserted, and can there be fixed by fasteners, having on a housing base of the housing housing connectors for connecting the housing to the shaft without play, wherein each fastener of the fasteners has a base surface arranged on an outer lateral surface of the housing and can be brought into engagement with the clamping holder using bores present in the housing, and has at least one recess in the base surface, such that the base surface rests on the outer lateral surface only in some regions.

2 . The component according to claim 1 , wherein the fasteners comprise clamping blocks and screws, and each clamping block of the clamping blocks has the base surface and the at least one recess in the base surface.

3 . The component according to claim 2 , wherein each clamping block has at least one through-hole for the screw, and the base surface is cut out in the region of the through-hole.

4 . The component according to claim 3 , wherein the recesses each have a diameter that is greater than the diameter of the through-hole.

5 . The component according to claim 3 , wherein several through-holes are present in the clamping blocks along the longitudinal axis.

6 . The component according to claim 2 , wherein each clamping block has a rectangular shape and a longitudinal axis and is arranged on the outer lateral surface in such a manner that the longitudinal axis is coaxial with a longitudinal axis of the housing.

7 . The component according to claim 6 , wherein each clamping block has at least one through-hole for the screw, and wherein the recess of the base surface extends along the longitudinal axis of the clamping block over the entire length of the clamping block, and has a width greater than the diameter of the at least one through-hole.

8 . The component according to claim 2 , wherein the base surface of each clamping block of the clamping blocks is concave or flat in shape.

9 . The component according to claim 1 , wherein the shaft has shaft connectors corresponding to the housing connectors and each housing connector of the housing connectors comprise a receptacle or a recess to which a corresponding shaft connector of the shaft can be connected.

10 . The component according to claim 1 , wherein the housing wall has a thickness of 0.3 mm to 3 mm.

11 . The component according to claim 1 , wherein the component comprises at least three fasteners arranged at a distance from one another on the outer lateral surface.
