Abstract:

An apparatus and method for compensating a radial load between relatively axially articulatable inner and outer members, which in the exemplary embodiment are a spindle cartridge and spindle housing of a slip spindle drill assembly. The apparatus includes a strut having a curved inner end seated in a first seat on an outer surface of the inner member, and a curved outer end seated in a second seat supportably retained by a cap disposed adjustably in an opening through the outer member. The strut applies a radial force between the inner and outer members to compensate for the radial load. The strut is also pivotally disposed between the inner and outer members, whereby the strut pivots during relative axial articulation therebetween. The strut is substantially disposed radially relative to a direction of axial articulation when the inner and outer members are relatively axially articulated approximately one-half the axial articulation range.
