Logan Clutches: How They Work

Pressurizing the cylinder forces the piston to clamp and lock the friction and steel separator discs. When pressure is removed, release springs separate the separator discs and maintain a running clearance between separator and friction discs. The amount of pressure controls the amount of torque.

 

Speed Changes

Change of speed in threading applications is accomplished through a limit switch and a solenoid-activated, directional control valve. At the prescribed depth, the limit switch is tripped by the threading slide shaft, signaling the threading clutch to change speeds. Low speed for tapping - Fast speed to back the tap out. (Left-hand threading applications require the inverse sequence).

 

Lubrication

Logan Clutch features

Since Logan Clutches operate at relatively high speeds, a steady metered flow of lubrication is required over the bearing and disc pack surfaces.
