In a friction clutch plate as the main function, both the performance requirements of the composite structure. Automotive friction materials are mainly used to manufacture brake linings and clutch plate. The use of asbestos friction materials mainly based friction material, with environmental and safety requirements of increasingly high, the gradual emergence of the semi-metallic friction material, a friction material composite fiber, ceramic fiber friction material.
1. Note clutch plate
by means of two clutches is a friction clutch plate smooth surface, and after axial compression to release a mechanism of driving force. Its two clutch plates axially greater the pressure, the greater the friction produced also transmitted to the operation of the extruder, the more stable normal. Under normal operating conditions the machine typically exhibit stable operation, no noise; clutch plate will not slip in the rated load, do not get caught, without departing from itself; while the clutch is released, and so it should be completely disengaged brick stopped without generating noises or the two other clutch plate separation is not complete and so on. Therefore, it is necessary to adjust the clutch plate clutch in a good gap, the gap will lead to a big slip clutch plates,Damage to the clutch plate, a small gap will make the clutch plate and the like are not easily separated. Generating a slip clutch plate separation is not complete and other reasons is also noted that the outer gap inappropriate following:.
a pressure between the clutch plates and the driven gear and the inner and outer press plate insufficient, the clutch pressure plate is not tight and causing slippage, not necessary to check if the gap adjustment of the platen surface and into the push plate is flat, is damaged, in general they should contact faces 80% or more, in order to make contact with two clutch plates normally not during operation slippage will occur, or be considered to replace the push plate into the platen or other parts, to avoid burned and other components of the clutch plate deformation damage.
b. Assembled incorrectly, resulting in the contact surface can easily reach 80% or more of the requirements of other components of the clutch plate engagement. In this case also make partial clutch plate wear or smashed. Thus, in the assembly should be carefully checked required flatness of each component, but also observe whether concentrically during test, to avoid wear on the platen and the ring gear.
c. In operation, if found badly worn clutch plate, cracking, burning, breaking, etc. where pressure, sick do not run, check each stop member should promptly see if maintenance needs to be replaced.
d. It must be noted for later quality films clutch clutch plate, the surface is not deformed, and warpage of the clutch plate poor tightness, will not only cause the clutch to slip, resulting in shutdown and would damage other components .
e. Cause serious damage to the clutch inner ring clutch plates run consistent discontinuity, tightly loosely offset angle is too large, the clutch plate binding plate not affect the normal operation of the clutch, slip easily burn and the other clutch plate member, should change the ring gear.
f. Pug too dry or too large, hard object in the brick card, resulting brick clutch load increase, leading to clutch plate wear or smash, e.g. factory firing annular kiln in the production process required for dry mud, thereby causing the clutch plate have occurred broke phenomenon. Therefore, in the production process must master the mud dry humidity.
g. Can not be stained with grease, sludge and other material on the clutch plate. In the clutch assembly films sure to check cleared the debris, or cause clutchIs slipping, affect efficiency.
2. The process for manufacturing the clutch plate clutch plate
(1) topping calendering process. Process Description: The non-asbestos fiber strand is impregnated in the resin, and then immersed in the dope. After drying, the non-asbestos fiber cord topping calender, manufactured by the strip, after winding, to hot pressing, a further heat treatment. Through the grinding process, dust marking. Final inspection packaging.
(2) Dryer dipping process. Process Description: The first non-asbestos fiber strands in the resin, dope impregnated and dried. Then, the winding which was hot pressing, for further heat treatment. Through the grinding process, dust marking. Final inspection packaging.
