Abstract
A method of making a high performance x-ray system having a rotating anode includes making target/tubular stem assembly and then assembling it to a rotor body assembly. This particular method reduces tube failure due to anode assembly imbalance and provides an improved rotating x-ray tube anode assembly.
Claims19
A method for connecting a target/stem assembly to a rotor body assembly for use in a rotating x-ray tube, comprising the steps of:
- providing a target;
- providing a large bore, thin-walled tubular stem;
- providing a bottom plate;
- connecting the bottom plate to the tubular stem;
- connecting the tubular stem/bottom plate combination to the target;
- machining the bottom plate to obtain proper target/stem assembly balance and proper alignment between the bottom plate and the target/stem assembly;
- providing at least one thermal washer;
- machining the thermal washer to exact tolerances;
- positioning the target/stem assembly proximate a rotor body assembly;
- positioning the thermal washer between the target/stem assembly and the rotor body assembly;
- and
- connecting the target/stem assembly to the rotor body assembly with a plurality of fasteners to form an anode assembly.
