Patent ID: 8740493

Claim:
A connection for transmitting rotation comprising: a first component having a shaft with male spline teeth on an outer peripheral surface of said shaft, said male spline teeth extending to an inner end of said male spline teeth, and a blocking portion of said shaft extending in an inner direction from said inner end of said male spline teeth; a second component has a hollow portion with female spline teeth on an inner periphery of a bore in said hollow portion, with said female spline teeth extending to an outer end, the directions inner and outer being defined extending into the bore; bolt holes formed in both said hollow portion and said shaft, said bolt hole in said shaft formed in a portion of said shaft receiving said male spline teeth; a bolt extending through said bolt holes, and securing said shaft within said hollow portion; wherein a distance from an inner end of said blocking portion to said inner end of said male spline teeth on said shaft is greater than a distance between an outer surface on said bolt to said outer end of said female spline teeth on said hollow portion; and said distances being such that said male spline teeth will not engage said female spline teeth at all, contrary to said bolt if a bolt extends through said bolt hole in said hollow portion, but not said bolt hole in said shaft.
