Abstract

The utility model discloses a friction clutch driven plate which is designed for solving the problems of small friction area and short service life of the existing friction clutch. The friction clutch driven plate comprises a driven plate substrate on which more than two through holes are positioned. And both sides of the driven plate substrate are coated with friction plates formed from the ebonite glued together with the flake asbestos. The utility model has the advantages of large friction area, firm structure and long service life.

Description

The friction clutch driven disc

Technical field:

The utility model relates to a kind of friction clutch driven disc, particularly a kind of friction clutch driven disc that uses in farm machinery.

Background technique:

At present, known farm machinery transmitting torque is most by friction clutch, the friction clutch driven disc is the critical component of friction clutch, friction clutch driven disc commonly used now is made up of a driven disc substrate and two friction plates, be shaped on several depressed parts on the friction plate, the depressed part that rivet passes friction plate is fixed on two friction plates the same side of driven disc substrate; The friction clutch driven disc of this structure has influenced the area of contact of friction plate owing to have several depressed parts on its friction plate, works as friction disc wear simultaneously to certain hour, and rivet comes off easily.

Summary of the invention:

The purpose of this utility model is to overcome above-mentioned defective, provides a kind of friction area big, sound construction, the friction clutch driven disc of long service life.

For achieving the above object, the utility model adopts following technological scheme: this friction clutch driven disc comprises on the driven disc substrate driven disc substrate and is shaped on plural through hole, is coated with the friction plate that bakelite asbestos powder gummed forms for one in driven disc substrate both sides.

The utility model is compared with prior art and since the driven disc substrate by hot-press gluing in the middle of bakelite asbestos powder friction plate, the on-chip through hole of driven disc is fixed together bakelite asbestos powder friction plate and driven disc substrate well; The surface of bakelite asbestos powder friction plate is a complete plane, and it is big to make the friction clutch driven disc of this structure have bigger friction area; The friction clutch driven disc of this structure has also reduced the required human and material resources waste of riveting process simultaneously, because friction plate of the present utility model is an integral body, also has rubbing surface end face run-out advantage little, long service life again.

Fig. 2 is the A-A cut-away view of friction clutch driven disc shown in Figure 1

Embodiment:

As shown in Figure 1 and Figure 2, this friction clutch driven disc comprises driven disc substrate 2, riveting has driven disc dish drum 4 on the center hole of driven disc substrate 2, be evenly distributed with a plurality of through holes on the driven disc substrate 2, be coated with the friction plate 1 that bakelite asbestos powder gummed forms for one in driven disc substrate both sides, friction plate 1 adopts the method and the driven disc substrate 2 of hot-press gluing to be blended in one; Described through hole be shaped as circle, semicircle, triangle, rectangle etc., on the periphery of driven disc substrate, be evenly equipped with breach.
