<p>A guard for a combination rotary drive shaft and universal joint includes a tubular member surrounding the shaft and a funnel-shaped member laterally enclosing the joint. An intermediate member interconnects the tubular member and the funnel shaped member. A bearing ring is engageable within one of the drive shaft and the universal joint and mounts the guard on the shaft and joint. To assemble the guard on the shaft and joint it is axially movable along the shaft with passageways formed by the intermediate member and the funnel-shaped member arranged to align with and move over outwardly extending locking tongues on the bearing ring. When a stop surface of the intermediate member contacts the locking tongues on the bearing ring further axial movement is blocked and the guard can be secured in position by rotating the funnel-shaped member so that the locking tongues are spaced angularly from the passageways in the funnel-shaped member.</p> |
