ABSTRACT:
A mechanism for reducing backlash in a spline connection between cooperably splined male and female members is disclosed. One of the members, either male or female, is formed in two coaxially alignable splined segments. The splined segments have end surfaces that are shaped to engage in sliding relationship so as to cause the two segments to undergo relative rotation when the segments are subjected to a relative axial load. The mechanism includes a connecting device for subjecting the two segments to such a relative axial load. In operation, the two splined segments are first oriented with their splines in alignment and are engaged as a unit with the other splined member. The connecting device is then applied to subject the two segments to a relative axial load so as to cause the segments to rotate out of alignment with one another and thereby securely engage the splines of the segmented member with the splines of the other member. The mechanism provides a secure, backlash-free spline connection that may be readily disassembled and reassembled in the field without any special tools or facilities.
