Friction coupler friction block

Abstract

The invention discloses a friction coupler friction block. The friction block b (9) is formed by a skeleton main body (6), a covering layer (7) and bosses (8); the skeleton main body (6) and the bosses (8) at two sides of the skeleton main body are made of a metal material and are integrally formed; the covering layer (7) is coated on the skeleton main body (6). Compared with the prior art, the friction coupler friction block has the advantages that the friction block made of rubber originally is divided into the skeleton main body and the bosses at two sides of the skeleton main body, which are made of the metal material, and then the friction block is combined with the covering layer to provide a hard force point for the pressing of a lever, so the deserved functions and effects of the friction block are ensured, and the friction block is safe, reliable, simple in structure and easy to manufacture.

Description

technical field [0001] The invention relates to a friction coupler, in particular to a friction block of the friction coupler. Background technique [0002] For mechanical and electrical equipment such as scraper machines and belt conveyors used in mines, hydraulic clutches or centrifugal friction clutches are mainly used in order to automatically connect the motor and reducer when starting, and automatically disconnect when overloaded. [0003] "A Friction Clutch" (Application No. CN201120249906.9, Authorized Announcement No. CN202125546U) is disclosed in the Chinese Invention Patent specification authorized and announced on January 25, 2012, such as figure 1 As shown, the friction coupling includes a friction disc 1 and a plunger seat 2, wherein two friction blocks a5 are evenly distributed on the radial side of the friction disc 1, and the friction blocks a5 are on both sides of the circumference of the side that is in contact with the friction disc 1. One end of the lev...

[0003] "A Friction Clutch" (Application No. CN201120249906.9, Authorized Announcement No. CN202125546U) is disclosed in the Chinese Invention Patent specification authorized and announced on January 25, 2012, such as figure 1 As shown, the friction coupling includes a friction disc 1 and a plunger seat 2, wherein two friction blocks a5 are evenly distributed on the radial side of the friction disc 1, and the friction blocks a5 are on both sides of the circumference of the side that is in contact with the friction disc 1. One end of the lever bracket 4 is fixed on the radial side of the friction disc, the friction block a5 is movably installed between the two lever brackets 4, the lever 3 is hinged on the lever bracket 4, and one end is connected to the adjacent side through the mandrel. The other end of the other lever 3 is hinged, and the other end is pressed against the boss of the friction block a5. When the clutch is overloaded, the lever 3 will use the lever bracket 4 as the fulcrum to press down the friction block a5. Since the lever 3 is made of metal The friction block a5 is made of wear-resistant rubber, so long-term pressing will damage the friction block a5, making it unable to achieve the preset functional effect
