Angle measuring system for measuring angle positions of 2 objects rotatable relative to each other by which division of graduated disc fixed at hub and connectable to 1 object being measured is scanned by

摘要

The fixing element (7) is used to fix a scanning unit (2) to the second object (10) being measured. The fixing element is an axial running projection (7) of the hub (6). Which axially is stiff and radially is elastically springy. The projection (7) before and during the mounting is pushed by at least one pressure element (8), from its rest position and for this is clamped with the scanning unit (2). The projection (7) in the measuring section is in its rest position, and has no contact to the scanning unit (2).
