Abstract
A mounting system for securing a rotating anode of an x-ray tube against axial movement locates a bearing on a stud projecting from a tube end wall and secures the bearing on the stud by means of a threaded fastener which is accessed through a central bore of the rotating anode assembly prior to closure of the tube vacuum envelope.
Claims11
A rotating anode mounting for x-ray tubes comprising:
- (a) a double-ended rotating assembly having a central bore open from end to end of said assembly and carrying:
- (i) an x-ray target anode,
- (ii) a motor rotor disposed at one end thereof and supported by a first bearing, and
- (iii) a second bearing disposed at the other end thereof;
- (b) an x-ray tube envelope having a stud coaxial with said central bore;
- and
- (c) fastening means accessible through said central bore to secure one of said bearings to said stud to prevent axial motion therebetween.

In an x-ray tube of the type having a bearing-mounted rotating anode assembly contained within a vacuum-tight envelope, the improvement comprising:
- (a) a hollow-central bore projecting entirely through said anode assembly,
- (b) rotatable fastening means axially driving against one end of an anode supporting bearing and adapted to be rotated by a tool projecting through said central bore of said rotating anode assembly;
- and
- (c) a cylindrical projection coaxial with said central bore, secured to said envelope, having a shoulder to receive and positively locate the other end of said bearing, and adapted to receive said fastening means to secure said anode assembly from further axial motion relative to said envelope.
1 more element
In a rotating anode x-ray tube, the improvement comprising:
- (a) a rotating anode and rotor assembly having a central bore therethrough and supported for rotation by a pair of ball bearings;
- (b) a vacuum-tight tube envelope having a threaded stud with a shoulder projecting inwardly from an end wall of said envelope coaxially with said central bore;
- (c) a threaded nut captured within said rotating assembly and positioned to drive one of said bearings onto said stud by a tool projecting through said central bore;
- such that said anode is positively positioned axially with respect to said envelope by locating said driven bearing.
