2.1.5 Illustrates a typical marine main propulsion application
where the clutch is mounted between the engine and
reduction gear. In this arrangement, the VC clutch is
combined with a Geislinger® flexible torsional cou-
pling.

2.1.6 Figure 8 illustrates a VC clutch mounting for punch
press applications. The drum and drum hub are
attached to the crankshaft or backshaft and the ele-
ment is attached to a bearing-supported flywheel or
bullgear. VC clutches on punch presses are typically
used in combination with Airflex type CTE and DBA
brakes.
2.1.7 Airflex can provide specific drawings covering the dif-
ferent mounting arrangements mentioned. The main-
tenance of the element assembly, tolerances and
wear limits of friction material, and alignment specifi-
cations in this manual apply to all VC applications.
2.2 Mounting Considerations
2.2.1 For clutch and brake applications, shaft alignment
must be within the tolerances indicated in the Align-
ment section of this manual.
Operation with shaft misalignment exceeding
the limits indicated in the Alignment section
of this manual will result in accelerated wear
of the element components. Severe misalign-
ment will result in excessive vibration and/or
overheating when disengaged due to drag-
ging of the friction shoes.
2.2.2 The element must be protected from contamination
from oil, grease or excessive amounts of dust.
Oil or grease contamination will result in a
reduction of developed clutch or brake
torque. Excessive dust contamination may
result in incomplete disengagement. Either of
these conditions will result in clutch or brake
slippage and overheating.
All rotating equipment must be guarded to
comply with applicable safety standards.
2.2.3 All mounting fasteners must be of the proper size and
grade, and torqued to the appropriate value. See
Table 1.
Use only the proper grade and number of
mounting fasteners. Using commercial grade
fasteners (Grade 2) in place of Grade 8 fasten-
ers (where called for) may result in failure
under load, causing personal injury or equip-
ment damage.
