Abstract
A machine and method for balancing wheels is disclosed whereby the wheel is affixed to and spun on a rotatable shaft to an initial velocity, the drive unit is decoupled and the forces of unbalance are measured during the first full revolution of the shaft after it reaches a predetermined measuring velocity. The initial velocity is selected as the lowest of a plurality of velocities which will yield a time from decoupling to measuring of unbalance of at least 2 seconds. Automatically activated drive and brake mechanisms are also disclosed as is a system of unbalance sensor arrangement having two movable sensors linked to one another at a fixed distance.
