Abstract
The angular measuring system has a hollow pick-up shaft whose end is slitted, and the slitted area has an interior thread. A screw with an exterior thread is provided for clamping the pick-up shaft in a bore of a driveshaft. The screw is turned into the pick-up shaft until it is axially supported on a detent. By further turning of the screw the thread flanks of the interior thread and of the exterior thread cause the slit end of the pick-up shaft to be spread open radially.
Claims4
An angle measuring system having a coding disk for measuring the angular position of a pick-up shaft and a clamping device for clamping the pick-up shaft, fixed against relative rotation, to a driveshaft of a drive unit, wherein the pick-up shaft has axial slits in the clamping area which can be radially spread open by an actuating element, the system comprising:
- a screw being the actuating element which can be turned in the pick-up shaft and which has an exterior thread in the clamping area;
- and
- a corresponding interior thread on the pick-up shaft in the clamping area, wherein the screw has an axially acting detent surface which it is supported against an axial detent of the pick-up shaft during clamping.
