Abstract
The invention relates to a device for securing an add-on part (10) to a substantially smooth drive shaft (12), comprising a slaving element (14), which is seated in a manner fixed against relative rotation on the drive shaft (12) and transmits a rotary motion from the drive shaft (12) to the add-on part (10), and further comprising a spring element (16), which axially secures the add-on part (10) on the drive shaft (12). It is proposed that the slaving element (14) penetrates the add-on part (10), and the spring element (16) is braced on the one hand on the slaving element (14) and on the other on the add-on part (10) and thus axially fixes the add-on part (10).

A device for securing an add-on part (10) to a substantially smooth drive shaft (12), having a slaving element (14), which is seated in a manner fixed against relative rotation on the drive shaft (12) and transmits a rotary motion from the drive shaft (12) to the add-on part (10), and having a spring element (16), which axially secures the add-on part (10) on the drive shaft (12), characterized in that the slaving element (14) penetrates the add-on part (10), and the spring element (16) is braced on the one hand on the slaving element (14) and on the other on the add-on part (10) and thus axially fixes the add-on part (10).
The device of one of the foregoing claims, characterized in that the spring element (16) is a circular cup spring (C-clip) that is open on one side.
The device of one of the foregoing claims, characterized in that the add-on part (10) to be secured is a vane wheel of a fan.
The device of one of the foregoing claims, characterized in that the slaving element (14) is press-fitted onto the drive shaft (12).
