  • Hydro-viscous speed regulating device for heavy-load start of belt conveyor
    Patent number: 10935084
    Abstract: A hydro-viscous speed regulating device for heavy-load start of a belt conveyor is provided. An input shaft and an output shaft are connected through a spline tube, an inner friction plate set, and an outer friction plate set. The inner and outer friction plate sets are controlled by an inner oil cylinder and an outer oil cylinder respectively. Oil inlet and oil return of the inner oil cylinder and the outer oil cylinder are controlled by an oil inlet valve core and an oil return valve core automatically. During starting process, pressure oil enters into the outer oil cylinder, and pushes the outer friction plate set to be engaged to provide torque required by the output shaft.
