INTERNALLY CURVED HYDRAULIC MOTOR CAPABLE OF TWO-WAY OIL DISTRIBUTION

WIPO Patent Application WO/2023/010392

A1

Disclosed is an internally curved hydraulic motor capable of two-way oil distribution, comprising two rotors fixed to each other, casings sleeved on the rotors, and an oil distribution cover connected between the two casings. The casings each comprises an output cover and a stator body; the output cover is fixed on the stator body; a curved guide rail is provided in the stator body; an even number of cylinder holes are evenly formed on each rotor along the circumferential direction; a radial plunger is provided in each cylinder hole; the top of each plunger is connected to a roller; and the outer peripheral surface of the roller is in contact with the inner curved surface of the curved guide rail. An oil distribution mechanism for distributing oil to the cylinder holes is provided between each rotor and the oil distribution cover, and the two oil distribution mechanisms are located on two sides of the oil distribution cover, respectively. The present invention has the advantage of achieving the two-way oil distribution in the middle of the motor, such that the motor structure is more compact, the flow distribution efficiency is higher, and the motor performance is more reliable.
