Shaft Locking Devices JIS CJ CJ Lovejoy Shaft Locking Devices expand to fill the gap between the shaft and hub, allowing for easy installation and removal, saving time over traditional interference fit techniques. The contact pressures created using a Shaft Locking Device can be greater than traditional interference fit pressures, allowing for more torque to be transmitted or shorter hubs to be used. The easy installation also allows the hub to be positioned more accurately on the shaft, and can facilitate angular timing of the hub. SF SF Lovejoy Shaft Locking Devices connect hubs solidly to...

Shaft Locking Devices Selection Process Minimum Outer Diameter of Hub The hub must be of a size to withstand the pressure exerted by the Shaft Locking Device without yielding. Use the following equations to determine the minimum hub diameter (Dmin) required. Yield point of hub material (psi) Form factor (see figure 1.) Alternatively, use the table below to determine the Coefficient K. To use the table, find the column corresponding to the Yield Point of the hub material (in psi), and the Form factor "f" from above (based on the hub's length through bore). Use the row with the pH from the specification...
