Type CH clutches are designed specifically for heavy duty clutch and brake applications, and can be air or hydraulically actuated.
The friction disc packs are suitable for either wet or dry operation. Actuation is accomplished through internal shaft and clutch passages.
When used as a wet clutch, coolant oil may be used as a splash or spray, or forced through the friction disc pack from an internal shaft passage.
The clutch hub is bored and keyseated for shaft mounting. Torque is transferred from the disc pack to a splined drive ring.
Standard Specifications:
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.
Modified Standards:
Higher torque ranges and actuation pressures are available to meet customer’s specific design requirements.
