Abstract
In an apparatus for retarding the measuring spindle of a balancing machine after a measuring run in which the measuring spindle is brought up to the measuring speed of rotation by means of a hand crank, the measuring spindle is retarded by the co-operation of first and second brake discs, one of which is non-rotatably connected to the measuring spindle while the second rotates with the measuring spindle during the measuring run but is held in a stationary position relative to the frame structure of the machine in the retardation phase. The second brake disc is arrested upon termination of the measuring run by a holding pin which is actuated to engage an engagement location on the second brake disc, in dependence on the angular position and the speed of rotation thereof, to provide controlled arresting of the brake disc.
