  • Process and apparatus for the input of parameters of a rotary member to be balanced into a balancing machine evaluation unit
    Patent number: 5172596
    Abstract: A process and an apparatus for the input of parameters of a rotary member to be balanced, such as a vehicle wheel, into an evaluation unit of a balancing machine in which a rotary member to be balanced is mounted on a main shaft and the respective rotary angular positions of the main shaft are monitored in angular steps by means of an angle sensor, and reproduced. For input of the parameters of a rotary member requiring balancing, the main shaft is rotated and signal produced by the angle sensor in the rotary movement of the main shaft is used to alter the respective value of the parameter being displayed, with the main shaft being rotated until the desired value in respect of the parameter in question is displayed.
