CH Series and How they Work
Pressurizing the cylinder with fluid or air forces the piston to clamp and lock the friction and separator discs, and release springs. Torque is transferred through the clutch to the drive cup. When pressure is lifted, the release springs take apart the separator discs and maintain a running clearance between separator and friction disc surfaces.
Type CH clutches are available in seven sizes with torque ratings from 49,000 lb-in (5532 Nm) to 1,280,000 lb-in (144,000 Nm).
Maximum allowable pressure is 200 psi (13,8 bar)
for wet operation and 120 psi (8,3 bar) for dry operation.
Standard operating speeds are from 1 to 2200 RPM. Stronger release springs are available for disengagement at higher speeds.
Higher torque ranges and actuation pressures are available to meet customer’s specific design requirements.
