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 lb.in
(233.000 N.m). 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.
Features
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.
Where used:
•
Power Presses
•
Tension Brakes
•
Emergency Stop Brakes on Unwind Stands
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.
Long wearing, self lubricating PolyPak* seals.
Eliminates premature twisting failure and requires no
external lubrication.
