The invention discloses a water-cooled motor with adjustable
coolant pressure. The water-cooled motor comprises a motor body, a first rotating shaft, a support, a first gear, a fixing groove, a transition mechanism, a first bearing, a combined
cam mechanism, an outer gear, an inner gear, a gear ring, an inner shell, an outer shell, a
water pumping mechanism, a water outlet
pipe, a
pipe body, a bracket, a throttling seat, a sealing head, a push rod, a first spring, a tension
pressure sensor, a bottom plate, a
servo drive mechanism, a cooling ring groove, cooling fins, a
coolant inlet
pipe, a
coolant outlet pipe and a
heat exchanger. The device has a simple structure. A
water cooling way is adopted, so that a good
cooling effect is achieved. Moreover, a pump and a
control system thereof do not need to be arranged separately;
high transmission stability and reliability are achieved; and the
cooling capacity increases along with the increase of the rotating speed of the first rotating shaft. At the same time, the liquid output pressure can be adjusted to meet the requirement of low-load start-up and make the coolant reach any place of a cavity between an inner shell and the outer shell, thereby increasing the
utilization rate of the coolant and improving the
cooling effect.
