Lovejoy Shaft Locking Devices

Lovejoy Shaft Locking Devices establish a secure connection between hubs and shafts, employing a keyless mechanical interference fit for torque transmission and axial thrust resistance. This method leverages screw tension within the Shaft Locking Device, converting it into radial pressure via an inclined plane. This pressure effectively expands the Shaft Locking Device to eliminate any space between the hub and the shaft. The Shaft Locking Device relies on the frictional bond between itself and the shaft/hub to create a backlash-free connection. Importantly, this connection can be easily disengaged to release the mechanical interference fit.

These Shaft Locking Devices expand to bridge the gap between the shaft and hub, simplifying installation and removal, which is more time-efficient compared to conventional interference fit methods. The contact pressures generated by Shaft Locking Devices can exceed those of traditional interference fits, enabling greater torque transmission or the use of shorter hubs. The straightforward installation also allows for more precise positioning of the hub on the shaft and facilitates angular timing of the hub.
