1) The drum gear coupling for the drum is a new type of flexible coupling, which is mainly used to connect the output shaft of the reducer of the lifting mechanism in the lifting equipment and the wire rope drum. It is also suitable for other similar Mechanical equipment that not only transmits torque but also bears radial load, but cannot be used as a transmission that needs to bear axial load. 2) The working temperature of the drum gear coupling for the drum is -25～+80°C; the nominal transmission torque is 16～560 kN·m; the allowable radial load is 18～355 KN. 3) Compared with other couplings for drums, drums for drums
