Installation and production of HL elastic pin coupling

　　HL-type elastic pin coupling is a nylon pin that penetrates into the pin hole on the coupling flange, and is matched with the half coupling to transmit torque.However, the pin hole needs to be quenched and tempered. Because the transmission time is too long, the pin hole will be enlarged and the tolerance will become larger, resulting in uneven force on the shaft hole of the coupling. Therefore, after the coupling is processed and formed The pin hole needs to be quenched and tempered with fire treatment requirements.The shaft hole tolerance of the elastic pin coupling generally follows the two standards of the Ministry of Machinery, H7 and H9, which can also be referred to as interference fit and transition fit for short.Among them, the interference fit refers to a positive tolerance, plus a tolerance of 10-20 wire. The difference between the small limit size of the hole minus the maximum size of the shaft is the large interference Ymax, which is the tight state of the hole and shaft fit.
