FSPA Package Description
Description
The FSPA flywheel clutch/brake package is designed primarily for stamping
press applications. However, it can be easily adapted to other types of flywheel machines requiring cyclic operation. The major components of the
package are:
1. An Airflex CB or VC clutch element.
2. An Airflex CS, CSA or CTE spring-applied air-released brake.
3. A flywheel or bullgear with anti-friction bearings.
4. Clutch and brake drums.
5. Airflex quick release valves.
6. An Airflex rotorseal or optional timing rotorseal.
The combination or separate clutch and brake drums are keyed to the
driven shaft. The bearing mounted flywheel or bullgear rides on the outside
diameter of the clutch drum hub. The clutch element is attached to the flywheel or bullgear. The brake is attached to and reacted by the machine
frame.
Operating air is introduced through a standard or timing rotorseal. Air to engage the clutch simultaneously releases the brake, allowing the driven
shaft to rotate. When air pressure is released, air from the clutch exhausts
through the quick release valves. The spring-applied brake engages, stopping the driven shaft.
The most frequently used mounting arrangement includes a combination
clutch and brake drum as illustrated in the components parts figure. An alternate arrangement provides separate drums for the clutch and brake allowing the brake to be mounted at any convenient point along the driven
shaft.
The flywheel can be grooved for drive belts and furnished with barring
holes to facilitate die set-up for stamping presses. An optional bumping pin
can be provided to mechanically connect the flywheel and clutch drum for
manually freeing a stuck press die. Gear teeth can be provided in the flywheel blank for crankshaft mounting the package on geared presses.
An Airflex rotorseal is furnished with the standard package. If the package
is to be used on the crankshaft of a power press, an optional timing
rotorseal can be substituted in place of the standard rotorseal. This device,
in addition to providing an air passage to the clutch, incorporates a four
cam rotary switch to control the operating functions of the press.
FSPA units are available in a large variety of sizes and mounting arrangements with clutch torques to 320000 lb·in (36200 N·m).
