Abstract
The invention concerns a rotational angle measuring arrangement for measuring angle dependent units of an encoding shaft which is journaled in a transducer housing. A stator coupling non-rotationally connects the transducer housing to the housing of a drive system that is to be measured, and the encoding shaft and a drive shaft of the drive system are non-rotatably secured to each other. To provide an improved angle measuring system when the stator coupling is positioned between the transducer housing and the drive housing, to prevent angle measurement errors and to facilitate the mounting of the transducer, at least one locking mechanism is provided. When the transducer, including the stator coupling, is detached from the drive housing, the locking mechanism causes the stator coupling to non-rotatably lock the encoding shaft to the transducer housing, and when the stator coupling is secured to the drive system, the locking mechanism permits the encoder shaft to freely rotate.
