ABSTRACT:
An x-ray tube (10) includes an anode (16), a cylindrical stem (22), and a rotor (24). The rotor (24) includes a cylindrical sleeve portion (32) and a head portion (34) which are joined together at a joint (36). The joint (36) is formed by a mating of a lip (46) in the sleeve portion (32) and a lip (48) in the head portion (34). The lip (48) of the head portion (34) fits about the lip (46) of the sleeve portion (32). The sleeve portion (32) is formed of a first material and the head portion (34) is formed of a second material, the first material having a thermal expansion coefficient greater than that of the second material such that the head portion (34) expands less than the sleeve portion (32) upon heating and thereby maintains the integrity of the joint (36) inasmuch as the head portion (34) overlaps the sleeve portion ( 32) in the region of the joint (36). The stem (22) is attached to the anode (16) at a first end (50) and attached to the head portion (34) at a second end (52). The stem (22) is attached at the second end (52) by both pipe threaded engagement and by brazing. A shaft (70) is mounted within the interior of the rotor (24) and connected to the head portion (34) by screws (80) having gettering properties. The shaft (70) is supported for rotation by bearings (66), and a collar (74) is incorporated to prevent debris from entering into the bearings (66).
