Benefits of technology

[0013] A further advantage of the present invention is that the hub, in an end region opposite the flange region, can be designed directly as transmission component, in particular as transmission drive shaft or even as sun wheel or else pinion, which is inserted directly in the transmission.
[0014] Then all that is necessary is for the drive shaft of the motor, in particular of the electric motor, to be inserted into the transmission or into the hub of the transmission and to be secured by means of the clamping element.

Problems solved by technology

In addition, the clamping element sits in the end-side flange region of the hub in a secure and slip-proof manner, and cannot be rotated radially with respect to the hub or slip off the latter axially.

Embodiment Construction

[0020] According to FIGS. 1a and 1b a clamping element R1 according to the invention has a basic body 1 which is designed in the manner of a circular ring and sits in a precisely fitting manner on an end-side flange region 2 of a hub 3.

[0021] At the other end, the hub 3 can be connected directly or indirectly to a transmission, an end region 4 opposite the flange region 2 preferably being designed as transmission component, in particular transmission drive shaft, pinion, sun wheel or the like and being integrated directly in a transmission. An output shaft (not illustrated specifically here) of a motor, in particular an electric motor, can be inserted through an insertion opening 5 in a precisely fitting manner onto an inner circumferential surface 6 in order then to drive a transmission preferably directly via the hub 3.

[0022] So that the motor output shaft can be fixed securely and detachably again in the region of the flange region 2 of the hub 3, the actual inventive clamping ...

Abstract

In the case of a clamping element for connecting a motor shaft to a transmission via a hub (3), in particular transmission component, such as transmission drive shaft, sun wheel, clutch or the like, with at least one fixing element (7) being inserted radially in the clamping element, the fixing element (7) is at the same time to form both a radial element for securing the clamping element (R1, R2) against rotation and an axial element for securing the clamping element (R1, R2) with respect to the hub (3).

Description

BACKGROUND OF THE INVENTION [0001] The present invention relates to a clamping element for connecting a motor shaft to a transmission via a hub, in particular transmission component, such as transmission drive shaft, sun wheel, clutch or the like, with at least one fixing element being inserted radially in the clamping element. [0002] Clamping elements of this type are known and customary on the market in extremely diverse forms and designs. [0003] They are used in particular as shaft-hub connections and transmit driving torques from, for example, a motor to a transmission. [0004] A disadvantage of the previous clamping elements is that a clamping ring frequently slips and cannot be easily fixed. [0005] The present invention is therefore based on the object of providing a clamping element of the type mentioned at the beginning which eliminates the above-mentioned disadvantages, with which fixing is facilitated, very high fixing forces are realized and which can be connected directly...
