The cap supports a tubular guard or shield in a coaxial position relative to the drive shaft. One or more lugs on the bearing are disposed to seat in corresponding slots formed in the cap. When the lugs are seated in the slots, rotation of the cap relative to the bearing causes the bearing and the cap to engage one another. A U-shaped clip is pivotally mounted to the cap and rotatable between a first position in which the clip extends into the slot and secures the lugs in engagement with the cap and a second release position in which the clip is retracted from the slot, thereby permitting relative rotation between the cap and bearing.

The guard may be restrained during normal operation for preventing entanglement of personnel or other apparatus with the rod assembly which continues to rotate within the tubular guard, or may be unrestrained during normal operation. When unrestrained, the guard is free to co-rotate with the rod assembly, but has a low moment of inertia such that the guard decelerates rapidly when restrained so as to prevent entanglement. An anti-friction interface between the guard and the rod assembly is formed by the material of manufacture of the guard itself or by bearings or bushings supported in an annulus between the guard and the rod assembly.

A ball is located in each groove and extends through respective windows in the cage. Preferably, the windows associated with the clockwise and counter-clockwise grooves extend circumferentially further than the windows associated with the longitudinal grooves. The cage carries an arcuate face that is one of a convex and concave profile and radially opposes the arcuate surface that is the other of the convex and concave profiles. The radial distance between the face and surface is such that axial movement between the race and cage is limited by intermittent contact of the face with the surface.

  • Patent number: 7301725
    Abstract: A disk drive comprises a cover plate with preload tension formed across the cover plate for increasing the stiffness of the cover plate. The preload tension is formed across the cover plate after the cover plate that was warped is secured to a base member of the disk drive to become un-warped. Such a cover plate with increased stiffness is not easily deformed and effectively minimizes propagation of noise generated from operation of the disk drive.

  • Patent number: 7040992
    Abstract: A constant velocity joint for use in a prop shaft of an automotive vehicle includes an outer race. The constant velocity joint also includes an inner race arranged within the outer race and a rolling element arranged between the outer race and inner race. A cage is arranged between the outer race and inner race such that the cage positions the rolling element therebetween. The constant velocity joint also includes a flange contacting the outer race. Torque is transmitted through the use of a face spline. A collar contacts the flange and outer race and secures the flange and outer race to one another in an axial direction.
