INTRODUCTION
Read this manual carefully, making full use of its
explanations and instructions. The “Know How” of safe,
continuous, trouble-free operation depends on the degree
of your understanding of the system and your willingness
to keep all components in proper operating condition.
Pay particular attention to all NOTES, CAUTIONS, and
WARNINGS to avoid the risk of personal injury or
property damage. It is important to understand that these
NOTES, CAUTIONS, and WARNINGS are not
exhaustive. Nexen cannot possibly know or evaluate all
conceivable methods in which service may be performed,
or the possible hazardous consequences of each
method. Accordingly, anyone who uses a procedure that
is not recommended by Nexen must first satisfy
themselves that neither their safety or the safety of the
product will be jeopardized by the service method
selected.
Nexen’s “DPC” (
Dual Friction Plate
) Clutches are
designed to mount on shaft ends, or through shafts using
a customer supplied Q.D. (
Quick Detachable
) Bushing.
The dual friction plate design eliminates thrust loading of
bearings when the “DPC” Clutch is connected to a
bearing supported Flywheel, Sprocket, or Sheave.
Five components are combined to install Nexen’s “DPC”
Clutch, and a Pilot Mount Clutch, or as a Sheave Clutch.
The five basic components (each sold separately) are:
Pilot Clutch Assembly, Sheave, Rotary Air Union Cap, Q.
D. Bushing, and Rotary Air Union.
The inner and outer assembles of the “DPC” Clutch
rotate independently.
When mounted on a through shaft, the outer clutch
assembly rotates, and upon engagement, the inner clutch
assembly becomes the driven unit.
When mounted on a continually running shaft, the inner
clutch assembly rotates, and upon engagement, the outer
clutch assembly becomes the driven member.
Nexen recommends mounting the “DPC” Clutch with the
outer clutch assembly rotating continuously; taking
advantage of the cooling effect of the fins to dissipate
heat generated when the clutch is engaged.
This unit has rotating parts. A guard that will
not restrict the flow of cooling air around the
unit must be used if the unit is installed in an
area where injury to an operator could occur.
