CH Series Clutches and Brakes
Logan CH clutches and brakes can be air or hydraulically actuated and can be used for either wet or dry operation. Pressurizing the actuating cylinder causes the clutch’s discs to clamp. Torque is then transferred from the disc pack to the splined drive ring. Type CH clutches are approved by the American Bureau of Shipping (ABS).
Torque range: 49,000 to 1,280,000 lb-in (5,532 to 144,000 Nm)
Typical applications: Marine propulsion, mooring winches, mine hoisting equipment, mining conveyors
Wichita HC clutches are an oil-immersed clutch designed for end-shaft or through shaft mounting configuration. The compact size of the HC makes these units ideal for incorporation within a gear housing. All torque transmitting members are designed to provide for continuous heavy duty industrial service.
Torque range – 8,511 to 191,028 lb-ft (11,540 to 259,000 Nm)
Typical applications – Marine Gears, Winch Drives and Conveyors
American Vulkan Meslu clutches are dry-running, pneumatically actuated double-cone clutches. They operate backlash-free and produce no axial load. Friction lining wear is automatically compensated for.
Torque range: 5,900 to 232,332 lb-ft (8 to 315 kNm)
Typical applications: Dredge pumps, marine drives, auxiliary drives
VC Clutches and Brakes
The Eaton Airflex VC element assembly is an air-actuated constricting drum unit. The VC’s ventilated design allows rapid heat dissipation. The torque is carried by torque bars, and leaf springs retract the friction shoes when air pressure is released. Because of this construction, all components are available as replacement parts when refurbishing the unit.
Torque range: 27,000 to 3,660,000 lb-in (3,050 to 413,057 Nm)
Typical applications: Grinding mills, marine propulsion, metal forming machinery
