OPERATION, INSTALLATION & MAINTENANCE INSTRUCTIONS

FOR AIRFLEX 225DP CALIPER BRAKES

O P E R A T I O N

The Airfle)^Caliper Disc Brake has been designed for industrial use in general stopping and tensioning ap plications. The opposed piston design provides bal anced braking action and permits fixed mounting of the caliper and disc. Symmetrical split construction facilitates installation and allows mounting from either side or at the center between caliper halves.

This split design permits the use of discs of different thicknesses and diameters.

Air or hydraulic pressure is introduced into the cylin der blocks at one of the two inlet openings. The bridge pipe connects the two cylinders, assuring equal pressure on both sides. Both pistons move simultane ously and squeeze the piston mounted friction shoe assemblies against the disc, causing braking action.

When the actuating pressure is released to " 0 " psi, a spring powered, self-adjusting, release mechanism re tracts the pistons and friction shoes, and assures run ning clearance between the friction shoe and the disc.

The shoe retraction and self-adjusting mechanism is contained inside of the caliper piston. In this way, the assembly is completely inside the caliper cylinder block and is not subject to tampering or contamina tion by foreign matter. The adjusting is done auto matically and no maintenance is required throughout the life of the shoes.

i

( I N S T A L L A T I O N

There are two parallel machined surfaces on the Air-flex 225DP Caliper Brake in the area of the mounting bolts; however, only one of these is intended to be used as a mounting surface. DO NOT mount the brake on the side where the Bridge Pipe, Item #10 on Page 4, would cause interference. The Caliper Brake unit is symmetrical, and to avoid the Bridge Pipe in terference, the unit can be positioned for either direc tion of rotation. The brake mounting bracket should be fabricated to butt against the lip adjacent to the machined surface. This bracket must also be of sturdy construction and rigidly mounted to prevent deflec tion during operation. LOCATION OF MOUNTING HOLES: First install the disc, and then clamp the Caliper Brake to the disc with either air or hydraulic pressure. CAUTION: Before locating the holes for drilling, make sure the brake friction pads completely engage the disc so they do not overhang the outer edge of the disc. The O.D. of the disc must not rub against the Cylinder Block, Item #3. It is very impor tant that the mounting bracket be properly aligned with the mounting surface of the brake.

It is recommended that two tapped holes ( 1 " 8NC-3 THREAD) be provided in the mounting bracket.

NOTE: The Mounting Screws, Item #1 and Lock-washers, Item #2, are furnished with the brake, and should be tightened to 300 FT.-LBS. TORQUE MINI MUM. The Hex Nuts, Item #17, are furnished primar ily for shipping purposes; however, they can be used for mounting where "thru holes" in the bracket are desired rather than tapped holes. With this arrange ment, relocate the lockwasher to the hex nut end and tighten to the above specifications. The "thru holes" must not be oversize — use 1-1/32" diameter drill maximum.

M A I N T E N A N C E

BLEEDING THE HYDRAULIC SYSTEM:

1. There are two bleed screws, a bridge pipe and a pipe plug on the cylinders. Select the ones which are located at the highest level on each cylinder.

2. Apply hydraulic pressure and hold it " O N " . Gently loosen the selected components and allow the air and a small amount of fluid to escape. CAUTION:

Re-tighten the component before releasing the ap plied pressure to avoid sucking more air back into the system.

3. Repeat Step No. 2 as many times as necessary to remove all the air bubbles from the system.

4. During this bleeding operation, make sure that an adequate supply of f luid is available to prevent air from entering the system.

FRICTION SHOE REPLACEMENT: - :

A visual inspection is all that is required to determine when the friction shoes should be replaced. Actual new lining thickness is 21/32" (not including the steel backing plate). When the lining thickness is worn to approximately 9/32", or within 1/8" of the mounting slot in the lining, new friction shoes should be in stalled. Damage to the piston will result if the lining is allowed to wear beyond this point.

REPLACEMENT OF THE FRICTION SHOES is a simple task and requires only a few minutes of time.

Refer to the Illustrated Parts List on page 4. First, WITH PRESSURE OFF, remove four (4) But ton Head Socket Cap Screws, Item #8, along with the four (4) Dyna Seals, Item #7. This will release the two (2) Friction Shoe Retainers, Item #6, and permit removal of the two Friction Shoe Assemblies, Item #5. IMPORTANT: Before inserting the new Friction Shoe Assemblies, it is necessary to force the pistons all the way back in the cylinders. If there is any resid ual pressure remaining in the cylinders, it may be necessary to loosen one of the bleed screws on each Cylinder, Item #3, to bleed off the pressure. Once the pistons are fully retracted, the new Friction Shoe Assemblies can be easily installed and secured with the retainers. * •

SHOE RETRACTION: . ^

The operation of the retractor mechanism can be described by using the Illustration on Page 7. Pin (2) is fixed to cylinder block (1) by snap ring (3). Piston

(5) is positioned by retaining rings (8) which slide along pin (2). Spring (10) is retained in the piston by washer (11) and snap ring (12). The force required to slide the retaining rings along the pin is greater than the force developed by the spring.

When pressure is applied, the piston moves outward, compressing the spring until washer (11) bottoms against spring guide (9). The pressure, acting on the piston diameter, forces the retaining rings outward along the pin. When pressure is removed, the retaining rings maintain their new position on the pin. The spring then retracts the piston until the spring guide

(9) bottoms against the piston. The gap between the spring guide and washer is equal to the clearance be tween the disc and friction pad.

PISTON REPLACEMENT

(.V.

AIRFLEX 225DP CALIPER BRAKES

First remove old piston and dust boot assembly.

Clean cylinder area and dust boot groove. Keep dust boot groove free of oi l !

Note: Pin, Item #2, and snap ring. Item #3 are not included in the kit and should be left in the cylinder block when removing the old piston assemblies or replaced after cleaning.

Dust Boot (item #4), Quad Ring (Item #6), and self-adjustment mechanism (Items #7, #8, #9, #10, #11 and #12) are assembled to Piston (Item #5) at the fac tory. IMPORTANT - Quad Ring (4) must match the particular actuating medium to be used. Kit 145862X i is for air or mineral base f lu id; Kit 145862Y is for vegetable base f luid.

Make sure Quad Ring (6) is properly seated in its groove. Coat this ring and piston wall with compat ible type of oil. Insert carefully in cylinder bore and over Pin (Item #2) retained in Cylinder Block (Item #1) from previous usage. CAUTION! Do not damage lips of Quad Ring.

Bond Dust Boot (4) to Cylinder Block (1) as shown in sketch herewith using a good grade of rubber-to-iron adhesive, such as Eastman 910 or Goodyear Plybond. .

HYDRAULIC GAUGES

0 -15,000 psi ENERPAC gauges permit visual reading of the pressure generated by the pump and prevent overloading of equipment to insure long, dependat^le service. Used where a specific force is required, or to determine the required force for an application.

Gauges are precisely calibrated and highly accurate—GF-230, GF-325. GF-350, GF-375 and GF-510 are within ±2% of full scale in accordance with Government standards. Gauges are calibrated to read in POUNDS, TONS, PSI (pounds per square inch), or PSI/TONS. Gauge adaptors pemnit fast, easy installation of gauges in the line (see page 51).

15,000 psi pressure gauge (Model No. GP-15S) has steel housing, maximum indicating pointer and extemal adjustable gauge pointer for easy recalibration. Wider range prevents gauge spring fatigue in high pressure systems when cycling in 8,000 to 10,000 psi range.

GA-884 MAXIMUM INDICATING POINTER FOR GAUGES

Red pointer with plastic face plate cover. Follows regular gauge pointer as pressure increases, then remains at maximum reading when pressure cycle ends and regular pointer retums to zero.

For indicating pre-selected pressures or loads; also for indicating maximum pressure developed after a test is completed. Resets to zero for next test or run. Fits gauges with 4" diameter face.

TEST SYSTEM GAUGES (±

These quality gauges let you read pressure up to 50,000 psi to accuracies of ± V2% full scale to determine the exact force of pressure t>eing developed in your test set-up. Gauges have spring loaded backs and rubber plugs for relief in case system is over-pressurized. Have maximum indicating pointer which moves with gauge pointer and remains at the maximum reading when regular pointer goes to a lower pressure. All models have 6" dials.

For burst test set-ups, gauge should be snubbed with an ENERPAC ?-way valve #72-750 with the valve and gauge teed off the pump outlet (see page 32).
