| Airflex Type DC Element Description | |||||||||||||||||||||||
| Type DC elements can be used as either pressure actuated clutches or brakes. They are available in single and multiple disc designs. Element construction and operation is illustrated in the figure. Pressurizing the cylinder causes the piston to clamp the friction disc assemblies between clamping plates. External springs ensure positive disengagement. Type DC elements are available in five basic disc sizes with static torque ratings to 2,061,000 lbin (233.000 Nm). Element sizes are indicated by the number of friction discs and by the disc diameter in inches. For instance, size 225DC has two friction discs 25 inches in diameter. | |||||||||||||||||||||||

| Favorable torque to size ratio. DC type elements are physically smaller than most other type clutches and brakes with the same torque capacity. Low inertia friction disc assembly. Reduces the overall inertia that must be started or stopped. Optional split friction discs. Allows removal of friction discs without disturbing other components of drive system in mid-shaft element arrangement. | |||||||||||||||||||||||
