ABSTRACT:
A shaft assembly has a shaft body, a first universal joint coupled to a first end of the shaft body, and a second universal joint coupled to a second end of the shaft body. A method for dynamically balancing the shaft assembly includes rotating the shaft assembly at a predetermined speed, determining a level of imbalance of the shaft assembly while rotating the shaft assembly at the predetermined speed, iteratively adjusting the position of the shaft body with respect to the first and second universal joints in response to the level of imbalance to determine an optimal level of imbalance while rotating the shaft assembly, and securely positioning the first and second universal joints with respect to the shaft body.
