Abstract
The cycle times of an automatic single station residual unbalance measuring arrangement for a tire-wheel assembly are improved by the application of servo control to the vertical displacement drive of an elevator. Information relating to a particular tire-wheel type is obtained by direct measurement and/or correlation with data associated with predetermined tire-wheel types. A computer controls the operation of a servo motor that controls the vertical displacement of the tire-wheel assembly onto and off of a precision spindle and chuck on which the residual unbalance measurement is performed. The arrangement affords rapid acceleration onto and off of the precision spindle and chuck, but a gentle engagement between the wheel-tire assembly and the precision chuck to avoid tire bounce and damage to the precision balancer tooling.
