Read-out system for wheel balancer

摘要

A read-out system and method for a wheel balancing machine employs means for determining the minimum angular displacement between a "balance point" on the wheel and a predetermined reference for a stationary portion of the machine using a first scale of displacement and means for converting the minimum angular displacement from the first scale to a second scale. Using the second scale for indicating the balance point enhances the sensitivity of the display means at the balance point. A method is carried out for indicating alignment between the balance point where weight is to be added to an unbalanced wheel to balance same and a predetermined reference position for the machine.
