Planet-gear-type static pressure coupling transmission mechanism

The invention provides a planet-gear-type static pressure coupling transmission mechanism which comprises a transmission module, a control module and transmission oil fluid. The transmission module comprises a double-rotor static pressure coupling transmission movement and a support, the double-rotor static pressure coupling transmission movement comprises a planet gear rotor and an independent gear rotor, a gear on the independent gear rotor is meshed with a planet gear in a planet gear rotor, the planet gear rotor comprises a planet gear, a sealing block and an end cap, the end cap and a sealing block are fixed together, the planet gear is arranged between the end cap, and the control module is a hydraulic control loop formed by hydraulic pressure and a flow control element. A coupler has start and overload protection capability and is high in transmission efficiency and easy to control. When magnetorheological fluid is used as the transmission oil fluid, the planet-gear-type static pressure coupling transmission mechanism has the advantages of high control sensitivity and easiness in realizing computer automatic control.
