发明名称 Shaft joint
摘要 A shaft such as a worm drive shaft for a movable barrier operator is disclosed. The shaft includes at least two shaft segments having connection ends. The shaft segments include respective connection ends permitting a first connection end to be joined with a second connection end by inserting a portion of at least one of the connection ends within the other connection end along the longitudinal axis of the shaft. The shaft segments may be retained by a resiliently expandable connector such as a snap ring. The connector may expand to permit the joining and then contract to be received within a surface recess on a connection end. The connector may be part of or pre-assembled on a connection end, such as by being positioned within a surface recess thereof. The connector may provide a pre-determined position for joining the first and-second connection ends.
