LUBRICATION
The most effective and economical way to lubricate the
“DPC” Clutch is with an air line lubricator. Available from
Nexen, the lubricator injects oil into the pressurized air,
forcing a constant oil mist into the air chamber.
Lubricator drip rate is properly set when an oil drop forms
in the lubricator sight gauge every twenty cycles of the
“DPC” Clutch. Locate the lubricator above and within ten
feet of the “DPC” Clutch.
NOTE: Use a low viscosity petroleum base oil, such as
SAE10. Synthetic lubricants are not
recommended.
For a “DPC” Clutch cycled infrequently, apply two or
three drops of oil into the air inlet every two weeks.
OPERATION
CAUTION
Before placing the “DPC” Clutch into service;
verify that all screws are secured to the proper
torque (See Table 4).
The “DPC” Clutch engages when air pressure is
introduced into the Cylinder/Drive Disc. Air pressure
pushes the Cylinder/Drive Disc against the Flange Mount
Disc, and forces the Cylinder/Drive Disc in the opposite
direction. This engages the Friction Facings with the
friction surfaces of the Flange Mount Disc and the
Friction Disc.
Torque is transmitted through the Cylinder/Drive Disc,
and Piston/Drive Disc Splines to the Splined Hub
attached to the Shaft with a Q.D. Bushing.
Heat generated at the friction surfaces is dissipated by
windage created by the fins on the Flange Mount Disc,
and the Friction Disc.
When air is exhausted from the Cylinder, Return Springs
pull the Piston to disengaged position.
CAUTION
Never exceed the recommended operating
speeds (See Table 5).
All parts of the “DPC” Clutch rotate. A guard
that will not restrict the flow of cooling air
around the “DPC” Clutch must be installed
if the “DPC” Clutch is installed in an area
where injury to an operator could occur.
