A method of balancing X-ray anodes wherein the anode rotor is dynamically balanced separately from the anode target, the anode target is then attached to the anode rotor to provide the assembled anode, and the assembled anode is then dynamically balanced. This sequential balancing method has the advantage that it results in an anode which remains balanced during operation at speeds up to and exceeding the anode's critical speeds, even though the dynamic balancing steps may be performed at speeds substantially below the anode's critical speeds. This is also convenient because at such low balancing speeds, the dynamic balancing steps can be performed in air rather than vacuum without concern for oxidation and spalling of the rotor bearings, excessive vibration, and potential safety concerns.
A method for balancing a rotatable anode comprising the steps of:
A balanced anode comprising a rotor being dynamically balanced in a first set of correction planes at a first speed and a target attached to the rotor in the manner to dynamically balance the anode in a second set of correction planes at a second speed.
A method of balancing a rotatable anode comprising the steps of:
A balanced anode comprising a rotor and a target;
A method for balancing a rotatable anode comprising the steps of:
A balanced anode comprising a rotor being dynamically balanced in a first pair of correction planes at a first speed below a first critical speed of the anode by adding or removing material from the rotor and a target attached to the rotor in the manner to dynamically balance at a second speed below the first critical speed in a second pair of correction planes by adding or removing material from the target.
