Problems solved by technology
[0005] The purpose of the present invention is to propose a new type of liquid viscous device for the technical problems of large occupied space, complex transmission structure chain, and difficult coordination and control brought about by the use of two sets of liquid viscous devices under the conditions of speed regulation and braking at the same time. Viscous transmission device, the braking mechanism and the speed regulating mechanism share a set of pressure control oil circuit, and the two parts work in harmony, and two functions of braking and stepless speed regulation can be realized at the same time on one device

Description
technical field [0001] The invention relates to a hydraulic viscous transmission device for speed regulation and energy saving of large and medium-sized fans and water pumps used in high energy consumption industries such as electric power, petrochemical, metallurgy, and coal, and also relates to a wear-free braking and dynamic dynamometer Hydraulic viscous braking device for loading equipment. Background technique [0002] Liquid viscous transmission technology is the third fluid transmission technology developed after hydraulic transmission technology and hydraulic transmission technology. Many products and devices have successfully applied liquid viscous transmission technology, such as: liquid viscous speed clutch, liquid viscous brake . The hydraulic viscous clutch is based on Newton's law of internal friction, relying on liquid viscosity and oil film shear to transmit power, and adjusting the output speed by changing the oil film gap. The hydraulic viscous brake is a...
