Twin Disc Clutches
TWIN DISC CLUTCHES
Advanced features and superior construction are the hallmarks of Twin Disc's Dry Clutches Offered in both air-actuated and mechanically-actuated models, Twin Disc clutches are available in diameters from 6" to 42" and capacities up to 276,000 lb. ft. torque.

Air Clutches
Twin Disc Air Clutches do not require adjustment for friction plate wear. Further, air clutches exert more torque for a given diameter because of the large air diaphragm providing the clamping force. Air clutches have the further advantage of being easily remote controlled. They can be readily tied into the machine cycle with push button control, automatic actuation through limit switches, or other devices. Control valves are of two general types. When sudden rapid engagement is permissible, a simple "on-off" valve can be used. Where smooth engagement or partial torques are required, a controlled pressure valve is selected. The pressure admitted through this type is proportional to the throw of the control lever. |

Mechanically-Actuated Clutches
Mechanically-actuated clutches require adjustment for wear on the friction plates. Twin Disc Mechanically-Actuated Clutches are easily adjusted with a simple single-point feature. Wear is a function of the energy of clutch engagement so no simple rule can be set as to how often adjustment is necessary. However, under average cut-off conditions, usually several thousand engagements can be made before take-up is required. The torque of a mechanically-actuated clutch is proportional to the degree of adjustment. Values set forth for Twin Disc clutches are torques that can be obtained with reasonable manual effort.
