Shaft to Component Coupling Clutch and Torque Limiter Mechanisms
Clutch Mechanisms and Torque Limiter Mechanisms
Mach III offers two options for coupling a shaft and a bearing mounted pulley, gear or other mating component: Clutch Mechanisms with Adapters and Torque Limiter Mechanisms with Adapters. Both feature a mechanism which slides on the shaft and is fixed with set screws and a customer supplied key. Both clutch mechanisms and torque limiter mechanisms are provided with customer specified bores in any size up to the maximum shown for each product. The face of the adapter is pre-machined to easily bolt to the supported mating component.
- Clutch Mechanisms with Adapters
Clutch mechanisms are air engaged and spring released to provide connect and disconnect functions between the shaft and component. Torque is linear in response to air pressure applied. Shaft and component are disconnected when air is exhausted.
- Torque Limiter Mechanisms with Adapters
Torque limiter mechanisms transmit a fixed amount of torque. The torque value is set manually through the adjustment of a nut. Once set, the nut is fixed with set screws. When the torque setting is exceeded, the torque limiter slips until the overload ceases. Friction torque limiters do not disengage automatically, so they do not require re-set. However, some means of sensing and stopping the overload condition must be in place, or the friction torque limiter will slip until it burns up.
