Problems solved by technology

[0002] The friction block for pneumatic clutches is a key component in industrial pneumatic clutches; the existing friction blocks for pneumatic clutches are cumbersome to assemble, have poor installation accuracy, and do not have the functions of impact resistance and shock absorption. Poor, the direction of the frictional force borne by the friction block during work is parallel to the bonding surface of the metal skeleton, which causes the bonding layer to become a stress concentration area and cracks and damages, reducing the service life of the friction block for pneumatic clutches , which also increases the cost of using
