Abstract

The invention provides a speed-regulation clutch, which comprises a belt pulley, a power input shaft sheathed in a connecting hole of the belt pulley, a fixed disc fixedly arranged on the outer side surface of the belt pulley, a large sucking disc connected with the fixed disc, a driving disc fixedly arranged on the power input shaft by virtue of a flat key and an iron core fixedly arranged relative to the power input shaft, wherein the side surface of the driving disc is provided with a cavity; the iron core is accommodated in the cavity and is internally provided with a coil opposite to the sucking disc; the fixed disc is also provided with a groove in which a magnet disc is arranged; the magnet disc is arranged on the power input shaft; multiple permanent magnet fixing discs are uniformly distributed on the periphery of the magnet disc and are internally provided with annular soft magnets opposite to the permanent magnets; when the coil is powered on, the sucking disc compresses the driving disc under the effect of a magnetic field; when the coil is powered off, the sucking disc is separated from the driving disc under the effect of a leaf spring. The speed-regulation clutch can be used for regulating the speed of equipment, saving energy sources, reducing machine abrasion and improving the machine working efficiency.

Description

technical field [0001] The invention relates to a water cooling system for an engine, in particular to a speed regulating device with different rotational speeds controlled by an electromagnetic clutch. Background technique [0002] The working principle of the existing equipment is: the engine drives the power input shaft and the impeller of the equipment to rotate through the pulley, the coolant in the equipment is driven by the impeller to rotate together, and is thrown to the edge of the equipment shell under the action of centrifugal force, and a certain pressure is generated at the same time , and then flow out from the water outlet or water pipe, and the pressure at the center of the impeller decreases due to the coolant being thrown out, and the coolant in the water tank is sucked into the impeller through the water pipe under the action of the pressure difference between the equipment inlet and the center of the impeller to realize the cooling of the coolant recipro...
