A system for dynamically balancing a wheel utilizes low speed (preferably 50 to 100 rmp) rotation of the wheel that can if desired be provided manually. In manual operation as the rotation is imparted to the wheel by an operator, the rotational speed of the wheel is measured, and an indicator notifies the operator when sufficient rotational speed has been imparted to the wheel to enable a balancing operation to be carried out. Thereafter the wheel is allowed to coast and decelerate until the sensed forces have adequately settled out, then the forces of imbalance transmitted by the rotatable shaft are measured. When the measurements are obtained, any detected imbalance of the wheel is displayed on a suitable indicator mechanism. |
