Torque tube with assembly assurance feature

摘要

A connection for transmitting rotating torque has a first component having a shaft with male spline teeth on an outer peripheral surface of the shaft. The male spline teeth extend to an inner end, and there is a blocking portion of the shaft extending in an inner direction from the inner end of the male spline teeth. A second component has a hollow portion with female spline teeth on an inner periphery of a bore. The female spline teeth extend to an outer end. Bolt holes are formed in both the hollow portion and the shaft. The bolt hole in the shaft is formed in a portion of the shaft receiving the male spline teeth. A bolt extends through the bolt holes, and the shaft is secured within the hollow portion. A distance from an inner end of the blocking portion to the inner end of the male spline teeth is greater than a distance between an outer surface on the bolt to the outer end of the female spline teeth on the hollow portion.

1. 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.
