Note pulleys when: 1, last cleaned before assembly must use petrol to ensure that all parts of a clean and dry surface to ensure that they meet with the close and no oil, there is enough friction. 2, the assembly with the inner hexagon bolt assembly also be applied before wash and dry gas, not the bolt or screw holes in the coating of oil or grease pulley designed to ensure there is enough after bolt rubbing self-locking ability. 3, within three hexagonal bolts fastening turns need to be installed in place in order to ensure uniform sleeve by axial force, ensure the pulley and the sleeve positioned coaxially good. 4, pre-installation check the measurement assembly with the hexagon bolt length to ensure that after mounting bolts can withstand the drogue blind hole the bottom pulley plant, in order to ensure a close fit cone pulley, and to ensure that the bottom of the blind hole bolt by reverse 5v pulley thrust, produce the same effect double nut locking principle. 5, after fastening the cable pulley check and adjust master, the relative position of the driven pulley, ensuring two rounds in the same plane and belt tensioner moderate. 6, the pulley cover should be intact and securely installed to ensure operation in a broken belt or pulley loose exits lead to major accidents. 7, the sleeve parts subject to wear, after a long run, the hole and chain groove damage may occur, should be checked before each assembly, spare parts found defective should be replaced in terms of motor speed and pulley diameter than the speed ratio = output speed: input speed = load pulley pitch circle diameter: Motor pulley pitch circle diameter pulley spb, Hengda Machinery (certification), the pulley by Texas Hengda Machinery Co.
