LOVEJOY SHAFT LOCKING DEVICES

Lovejoy Shaft Locking Devices connect hubs solidly to shafts, using a keyless mechanical interference fit, to transmit torque or to withstand axial thrust. This mechanical interference fit utilizes screw tension in the Shaft Locking Device, converted into radial pressure via an inclined plane. This pressure expands the Shaft Locking Device to eliminate the gap between the hub and the shaft. The Shaft Locking Device uses the friction bond between the Shaft Locking Device and the shaft/hub to create a zero backlash connection. This connection is easily releasable to remove the mechanical interference fit.

Design benefits

* Eliminate cost of machining keyways or splines

* Reduce the shaft stress by removing keyways or splines

* Eliminating keyways often allows the use of a smaller diameter shaft

* Can place anywhere on shaft, and allows for easy angular timing

* Easy removal without damaging the shaft or hub means easier maintenance for the customer
