Mechanical Shaft Lock Mechanical Shaft Lock POSI-LOCK Application Machine tool, pump, molding machine, printing machine, palletizing robot, various jigs and tools Connects the Shaft and Hub with the Wedging Action of the Tapered Surface The shaft and hub are connected with the wedging action of the tapered surface. The machining tolerance of the shaft and hub is just the general fitting tolerance and no special finishing is needed. Compared to the key connection, high precision machining such as keyway machining is not needed, and the shaft and hub can be connected with high concentricity.

Mechanical Shaft Lock Product Lineup The sleeve's internal/external diameter ratio is small. The mounting part's diameter as well as the moment of inertia can be reduced. The mechanism is simple and high concentricity can be maintained. ■ Operating Principle Tightening the clamping bolt moves the outer sleeve in the shaft direction. At this point, the wedge action of the tapered surface with the inner sleeve generates a force to press the inner surface of the shaft and hub and this force connects the shaft and hub completely. The groove of the inner sleeve increases the wedge effect so a...

A simple structure and rigid parts provide uniform transmission and can withstand heavy load. A short shaft direction length saves space. CLUTCHES & BRAKES ■ Operating Principle Tightening the clamping bolt moves the 2 tapered rings in the shaft direction. At this point, the outer ring and the inner ring independently generate a force to press the inner surface of the shaft and hub due to the wedge action of the tapered surface and this force connects the shaft and hub completely. Front taper ring Outer ring Clamping bolt Max. rated torque Max. rated thrust Applied shaft diameter Operating...
