Operation
The Wichita Combination Clutch/Brake
provides fast, smooth cycling for stamping
presses and metalforming equipment.
The simple air-tube concept combines an air
actuated clutch and spring-set brake in a
compact, pancake assembly that prevents
overlap. The extra fins and cooling slots allow
for excellent heat dissipation. A low stress
spline eliminates driving pins between the
shaft and centerplate, while the precision die
springs provide con sis tent long-life braking
action.
The high performance air-tube design in sizes
380 and above, with optional quick air-release
valves, provides faster cycling than piston
and cylinder models. There are no o-rings or
piston seals to wear-out and leak, and no
lubrication or adjustment is necessary. Worn
friction plates can be relined at Wichita’s
factory on an ex change basis.
Installation of the CCB is also easy. The
simple air system has external connections
and requires no shaft seals. Metric mount ing
and SAE fasteners are standard. Available in
eight sizes with an optional hub for shrink
disc mounting. Clutch capacities through
340,000 lb.in. and brake torque through
250,000 lb.in.
Wichita Combination Clutch/Brakes are
manufactured and assembled in the United
States and backed by a global sales, service
and distributor organization.
Wichita CCB is ideal for
retrofit applications.
The simple external air
system with quick release
valves provides smooth,
fast cycling.
Optional
Optional shrink disc hub provides ease of
mounting with no keyways.

Clutch/Brake Selection
A typical Combination Clutch/Brake application
w
ould be on a geared punch press. To properly
select a CCB the fol low ing application
information is needed.
1. To determine the proper Application Duty
Factor for a Geared Punch Press, consult
page 16. Under Duty “B” or Normal, the
Duty Factor is 1-1/2.
2. To determine the application clutch torque,
t
he following information is needed:
a. Torque @ Crank
= (Rated Tonnage) (2000 lb./ton) (Torque
A
rm)
b. Torque Arm = y = (c) (tan a)
c = a + b - x
=
3 + 36 - .25
= 38.75 in.
b
2
+ c2- a

Cos α =
2bc
(36)
2
+ (38.75)2- (3)
2
=
(2) (36) (38.75)
= .99948
= 1.8478°
c. Torque Arm = y = (c) (tan α)
= (38.75) (tan 1.8478)
= (38.75) (.03226)
= 1.25 in.
Torque @ Crank
=(Rate Tonnage) (2000 lb./ton)(Torque Arm)
= (200) (2000) (1.25)
= 500,000 lb.in.
Required Torque @ Clutch
(Torque @ Crank) x (Crank shaft RPM)
= lb.in.
Clutch Shaft RPM

Selection
Press clutch and brake selection is
based on:
1. Application Duty Factor
2. Application clutch torque
3. Application brake torque necessary
to stop
4. Maximum Energy Input
5. Heat generated during cycling
6. Bore size

combination clutch/brake.
a. Kinetic Energy =
(WR

)(CCB RPM)
2
5,873
KE =
(1041)(204)
2
= 7,376 lbs.ft.
5,873
b. Maximum energy input to the CCB 600
is 14,229 ft.lbs. Therefore, CCB 600 has
sufficient energy input capacity.
5. To determine the Heat Horsepower
Capacity of the CCB at backshaft speed,
you need the following in for ma tion:
a. Heat HP capacity of CCB 600 @
200 RPM. (Look up capacity under the 200
RPM heading on page 16.)
Heat HP = 3.7 Heat HP @ 200 RPM.
b. To determine the Cycles Per Minute
Ca pac i ty, you need the following
in for ma tion:
(Heat HP @ CCB speed) (1.9 x 10

)
(WR
2
) (RPM)
2
or
3.7 (1.9 x 108)

Final Selection:
CCB 600 with 1/2 spring compliment. Also available
with shrink disc shaft mounting.
(See pages 18–19 for various mounting
arrangments).
Note:
This application example is for preliminary
sizing only. Contact a Wichita Sales Engineer
or the factory for final selection.
Application selection torque = the required
torque of 73,529 lb. in. x 1.5
= 110,294 lb.in. (Application Duty Factor for

Geared Punch Press”, page 16.
Preliminary selection of CCB based on clutch
torque is the CCB 600 with 50% spring

ompliment. The clutch torque for this model
is 124,350 lb.in. @ 80 PSI.
d. Maximum bore for CCB 600 is 5.0 in. bore
a
cceptable.
3. To determine application brake torque necessary
to stop the equipment the following information
is needed:
a.
The inertia of rotating parts referred to the
backshaft. It is given in the application data
that the inertia (WR
2
) of parts on the
crankshaft is 39,091 lb. ft.
2
at 30 RPM. To
calculate WR
2
referred to the backshaft:
30 RPM of Crankshaft
2
x 39,091 lb.ft.
2
204 RPM of Backshaft
= 845 lb.ft.2@ 204 RPM
Total WR2referred to backshaft is:
845 lb.ft.
2
+ 78 lb.ft.2= 923 lb.ft.
2
(WR2of parts on backshaft from application
data)
Total WR
2
to start and stop is:
923 lb.ft.
2
+ 118 lb.ft.2= 1041 lb.ft.
2
(WR2of CCB-600 from page 15)
b. The brake stop time required is 120°. (Based
on rotation at 30 RPM).
