ABSTRACT:
An apparatus for measuring unbalance on a rotary member such as a motor vehicle wheel comprises a drive motor for driving a main shaft carrying the rotary member, by way of a reduction transmission means having a self-locking action so that the main shaft can be braked by the self-locking action after an unbalance measuring run. The self-locking action of the reduction transmission means also serves to resist a rotary moment applied to the main shaft when tightening or loosening a clamping arrangement with which the rotary member is clamped on the main shaft, so that the main shaft remains in a stationary position during that operation.
