FAW 13179 I OPERATION A. DESCRIPTION B. HOW IT WORKS The Airflex type "E" element assemblies are air actuated, radially expanding units, primarily designed for slip clutch and tension brake applications; however, they are also suited for medium speed cyclic operation and high acceleration loads. The Airflex type "E" element is available with two different friction shoe designs. The type "VE" element is available with one friction shoe design. The design features of the friction shoe assemblies are illustrated below. The neoprene rubber and cord actuating tube (4) is the primary moving part in the Airflex type "E" element assembly. When air pressure is introduced to the element assembly, the tube expands radially. This causes the release springs (7) to compress and the friction shoes (6)tomakecontactwiththefriction drum. The frictional force or torque is controlled by tl-ra-;,, amount of applied air pressure, i.e. at 50 psig ;an V element will have twice the torque it would have; at 25 psig. \ ,,f When the air pressure is releasedvjor decreased, the release springs assure total apd positive retraction of the friction shoes (6). , - 'T Torque is transmitted from the friction shoes to the torque bars (5) and itb^the housing halves (Z' & 3) of the assembly., f Type "E" used for light duty slip applications. The maximum recommended, gir pressure is 11 O psig for cyclic applications^.^Qipsig for air cooled slip application^arid 3Q.p&igfor water cooled slip applica tions. ,fc?mitty/m air pressure is 5 psig on ail slip applications! /'* Vv/ Type ventilate applications. "E" used Th.e'Airflex t2:E4T5 element offers a unique feature . withl'the use of lock-out bars. These are pins which ./slide througM the housings and friction shoes and / prevent" tfie shoes from making contact with the frichpn? drum. This feature allows the use of higher, mqreycbntrolabfe air pressure when lower torque for medium dutyH slip Sis required. k.*' NOTE: When using lock-out bars, shoes must be locked out in pairs and always diametrically opposite. The type "E" element assembly is available .dual, mounted for greater -torque and thermal capacity. A variety of mounting components for either clutch or brake applications are available. C. ELEMENT ADJUSTMENT , The airflex type "E" elements require no adjustment or lubrication. The flexibility of the rubber tube com pensates for friction shoe wear and there is no metal to metal contact such as mechanical linkage, springs, gears, etc. to require lubrication. 11. INSTALLATION Caution Air inflation of the Airflex element tube with out a frieddp-drum in place may cause permanent dam age to. tHe element. A.. MOUNTING The element must be inserted squarely onto the hub register and the mounting bolts equally torqued. The element must be properly centered within the friction drum so as to provide adequate running clearance. B. ALIGNMENT Good alignment is essential for optimum clutch per formance and consistency. Misalignment results in vibration and preloaded bearing, gears and other machine components. These factors reduce the service life of other machine components considerably. To extend the service life of machine components, we recommend the closest possible alignment. FAW 13180 C. AIR SYSTEM Typical control systems shown on page 4. I he Airflex rotorseal is designed to give trouble-free service under the most severe conditions, without requiring special attention. 1. AIR PIPING Pneumatic piping should be free of foreign material such as pipe dope, metal chips, etc. Pipe ends should be reamed after cutting to prevent reductions of effective pipe diameter. Selecting the proper size of pipe and valve is very important for proper operation in cyclic applications. Keep the number of 90 elbows amf sharp bends to a minimum and avoid the use of stioet elbows in piping. . Due to the extreme accuracy and close tolerance on internal parts, considerable care is required when rebuilding rotorseals in the field. Many customers consider the rotorseal as a disposable item since a replacement is relatively inexpensive. See operation and maintenance instructions per table 1. ..Undersized pipe or air system components will cause sluggish response, and may contribute to accelerated wear of friction lining. Air line lubricators are not required for the Airflex element and, if used, should be of the nonadjustable mist type. ' Rotorseal Type AA2, B2, 03, C2 RH Maintenance and .

AIR TANK BT , ./ V--,: ,059070 For elements operating on rapid cyclic duty an air accumulator tank with pressure regulator and gauge TABLE 1 is recommended except in those cases where the installation may be near a large supply line.. Always install the pressure regulator in the supply line to the tank and provide a drain at the bottom for blowing off condensation which may accumulate in the system. 5.QUICK RELEASE VA.LYE The air tank also serves as an excellent filter.

POINTS TO CHECK WHEN INSPECTING THE > AlRfLEX ELEMENT: 1) The wear and condition of the friction shoe assemblies* See Figure E for wear gap measurement. See Table 3 for max imum allowable gap. See Table 2 for minimum lining thickness. a) If the friction linings are glazed, this condition can be corrected by sanding the friction lining to remove the glaze. Linings that have been worn to the minimum allowable thickness should be replaced. MOLDED BLOCK E SERIES ELEMENT SIZE MINIMUM ALLOWABLE UNJ6 THICKNESS tin.) MAXIMUM ALLOWABLE KM ON DfOJK DIA.

If friction shoes have been contaminated, they should be re moved and cleaned. (See instructions below for friction shoe replacement.) For light contam ination, Fuller's Earth may be used to remove . grease dr oil from the friction lining surface. If the lining is saturated with oil or grease, a sol- * ' vent such as VM and P Naptha .pr Petroleum Ether should be used to degrease.the lining. .; A cloth dampened with the solvent .may .be, used to wipe the grease off the jinihg, or tfid friction shoe assembly may be dipp&d into the solvent.

To replace broken springs, : follow instructions under Replacement of Friction ; Shoes. |f the element is exposed to severe contaminaV; tion, a deposit may form. This can prevent the friction shoes from retracting. To correct this condition, the friction shoes must be removed(per instructions below) and deposits cleaned off. d) Heat curing of the rubber can harden the actu ating -tube-so much-that--it actually-resists proper friction shoe retraction. If a tube is in this condition, it must be replaced.

REPLACEMENT OF FRICTION SHOES AND ' RELEASE SPRINGS Friction shoes should be replaced or relined when the friction material has worn down to the minimum allowable lining thickness shown in table 2. Excessive lining wear may cause the release springs to break and may also result in scoring of the friction drum surface. REPLACEMENT OF RELEASE SPRINGS Procedure: Place blade of screwdriver on the end of the release spring. By striking the screwdriver with a hammer, the spring is pushed through the slot and out the opposite side. It can then be grasped and pulled out- 5 NOTE: Any element assembly with 60# springs has two springs (installed piggy-back) per friction shoe assembly. To install, insert replacement spring into the appropriate slot with the curved part toward the tube (see cut away view on Page 1). Drive the spring into the slot until the dimple on the spring seats into the hole in the backing plate. Expand rivets by driving pin flush with head of rivet as shown. ` REPLACEMENT OF FRICTION SHOES Remove release springs (see `above). With the springs removed the friction shoes will slide out easily. A screwdriver may be required when removing the first shoe. The rest of the shoes should slide out easily. It is not necessary to remove torque bars. NOTE: When the friction shoes are removed, the rubber tube is exposed and should be visually in spected and all foreign material removed. It Is not necessary to pse fop. hard a blow since rivet drives easily^ \ The following is a description of the three different friction shoe assemblies shown on page 2. A) Style "E" The friction block is bonded and screwed to a metal backing plate. The entire assembly must be replaced as a unit- 2) Removal of block (where''wedge-type rivets are used) to removereplacement blocks drive pin out of rivet, a'^.shqwn/'arici-either shear off with sharp single-bevel chiseror drill out rivet with 1/4" drill.

V*'1 Step A 1) Remove old block by fshearing: offupset portion of rivet with a sharp, singVe.irevel chisel. A dull chisel will distort rivet and mutilate holes ip backing plate. 2) Remove rivets amfbfock. . * 3) Clean all foreign matter from backing plate. To assemble "Ventilate E" friction shoes 1) Fastening mew biock (with wedge-type rivets) lay on new; block'and insert all wedge-type rivets. Clamp block tightly to backing plate being sure that backing plate is^vfciacked up" on curved surface so that the backing.pfate lip is not bent out of shape. 2) Using B.F. Goodrich Rivnut Header (available from Airflex Plant) select one of Rivnuts furnished with new block and engage all threads of the Rivnut on the pull-up stud. (See Fig. C). Hold hex nut and rotate by hand the Allen bolt with hex counter sunk hole (called the jack screw) until head of rivnut is snug against shoulder on tool. Insert Rivnut through hole in one corner of friction block and backing plate. 6 FAW 13184 3) Place Allen wrench in socket of jack screw and hold stationary. Turn-hex (Fig. D) in clockwise direction with a wrench while holding Rivnut Header at right angle to the work. Power is best applied through angle shown. , . 4) Turn the nut Until firm resistance indicates complete upset of the Rrvnut. Approx. 1 to 1-3/4 turns wifi be required. 5) Break nut loose with counterclockwise movement of end wrench. Remove both wrenches from the tool. 6) Remove tool from Rivnut by revolving entire tool in counterclockwise direction. 7) Repeat above operation with successive Rivnuts working diagonally from corner to corner, and then following in like fashion between the two remaining corners. Then fill In any remaining holes. - 8) Repeat on remaining friction shoes until the entire set has been refined. To install new or relined friction shoe assembly, reverse disassembly procedure. E element - IV REPLACEMENT OF ACTUATION TUBE The type "E" elements are available with either a continuous or butt end tube. The butt end tube is a "wrap-around" style which can be installed without having to remove element from the shaft. To remove tube, disassemble springs, friction shoes and torque bars. Split the element halves. Remove tube stem nut. Remove tube. Clean both housing halves thoroughly!! To assemble, reverse the above procedure. V NOTE: The tube stem nut should be torqCied to 55#ftr''0.
