ABSTRACT:
A disk is connected with a hub in an angle measurement apparatus and a scanning arrangement is provided for scanning a graduation on the disk, the hub is not supported in the scanning arrangement, but is connected with an externally supported drive shaft of a drive unit, the angle measurement apparatus is preassembled in such a way by the manufacturer of the measuring instrument, that the recipient can place it on the drive shaft of the drive unit and fasten it there without having to perform any adjustment. So as to preserve the axial spacing as well as the radial correlation between the scanning arrangement and the graduation predetermined by the manufacturer of the measuring instrument during the transportation process as well as during the mounting operation of the angle measurement arrangement to the drive unit, two clamping clips are inserted by way of clamping elements between the hub and the scanning arrangement, apertures in the cover and in the scanning arrangement are provided for insertion of the clamping clips and the clamping clips are slid through these apertures into grooves in the hub, the clamping clips are removed from the angle measurement apparatus after the angle measurement apparatus has been installed.
