COUPLING MOUNT CLUTCH-BRAKE
1.
Determine the parallel misalignment of shafts to be coupled by
placing a straight edge across the shafts and measuring the
maximum offset at various points around the periphery of the
shafts. Make the necessary corrections to keep the shafts
within parallel misalignment limits of the clutch coupling (See
Figure 3 and Table 2).
NOTE
Before installation, the driving shaft can be fixed but the
driven shaft must be allowed to “float” (See Figure 3).
Align the air inlet ports to the six o’clock down position to
allow condensation to drain out of the exhaust port.
2.
Insert the first Key (Item 30) into driven shaft (See Figure 3).
3.
Slide Clutch-Brake Assembly onto the driven shaft (See
Figure 3).
4.
Insert second Key (Item 30) (See Figure 3).
5.
Install and tighten Set Screws (Items 27 and 28) to the
recommended torque (See Figure 3 and Table 3).
6.
Attach the Coupling Adapter Plate (Item 24) to the Clutch-
Brake pilot using Cap Screws (Item 33) and Lock Washers
(Item 34); then, tighten the Cap Screws to the recommended
torque (See Figure 3 and Table 3).
7.
Place the Coupling’s Flexible Disc (Item 25) over the pins in
the Coupling Adapter Plate (Item 24) (See Figure 3).
8.
Insert the customer supplied Dodge™ Taper-Lock Bushing
into the Coupling Hub (Item 26) (See Figure 3).
9.
Align the holes (not the threads) and slide the Dodge
TM
Taper-
Lock Bushing Assembly onto the driving shaft until it is flush
with the shaft (See Figure 3).
10. Thread the screws into threaded holes in the Dodge
TM
Taper-
Lock Bushing and Coupling Hub (Item 26); then, alternately
and evenly tighten the screws to the bushing manufacturer's
specifications.
11. Align the pins in the Coupling Hub (Item 26) with the holes in
the Flexible Disc (Item 25) (See Figure 3).
12. Push the entire assembly together. Automatic spacing is
accomplished by spacers molded into the Flexible Disc.
13. Fasten one of the ears of the Clutch-Brake to a fixed member
of the machine.
NOTE
The Piston Air Chamber (Item 7) floats laterally
approximately 1/16 inch [1.59 mm] during operation.
Make sure the securing pin allows 1/16 inch to 1/8 inch
[1.59 mm to 3.18 mm] movement.
