  • Publication number: 20160101854
    Abstract: The present invention relates to a gyroplane comprising rotating wings with hydraulically-operated fan propellers. The rotating wing (6) with hydraulically-operated fan propellers comprises a radial hydraulic motor (6-2) and hydraulically-operated fan propellers (6-1). A wing rotating intermediate spar supported on a bearing (6-5) in a bearing support fixedly connected to a rotating wing fuselage (6-4) is fixedly connected with a wing rotating cantilever spar (6-3). A left wing rotating cantilever spar on the left side of the rotating wing fuselage and a right wing rotating cantilever spar on the right side of the rotating wing fuselage are fixedly connected to the wing rotating intermediate spar and distributed in bilateral symmetry. The wing rotating cantilever spar (6-3) is fixedly connected with the front end and the back end of a motor front connecting plate (6-2.2) and a motor back connecting plate (6-2.

  • Publication number: 20160069358
    Abstract: The hydraulic motor drive device uses a radial hydraulic motor to drive a hydraulic pump for pumping pressure oil to form hydraulic energy and also uses the radial hydraulic motor to be configured as hydraulic energy for driving an executing element of a configuration load; a cylinder liner of the radial hydraulic motor is eccentrically and fixedly connected to the set circumference of a motor spindle of which the left end is supported by a tapered roller bearing fixedly connected in a motor left end cover of a left under-chassis and of which the right end is supported by a tapered roller bearing fixedly connected in a motor right end cover of a right under-chassis, so as to drive the motor spindle to rotate and operate; because hinge bars accept the transfer force by an engagement point and the force transferring direction is the direction of transferring the oil pressure configured according to the system need, namely that the direction from pushing a plunger in the cylinder liner by the oil pressure to pus
