Split vane fixed type vane motor in which only a vane is pushed out by a forming body to strongly generate rotational power.

Generally, a vane of a vane motor, either a pressure balanced type vane motor or a pressure non-equilibrium vane motor, is supported by a plurality of springs depending on a spring and is formed on the rotor in a radial direction, and receives a force of a fluid pressure applied at the inlet, . And, the power generation of the vane motor is caused by the pressure of the fluid flowing between the vane and the vane is greater than the force generated by the vane surface of the rotor in the direction of rotation of the rotor, And a rotational power is generated by pushing out the vane surface of the vane opposite to the direction of rotation of the rotor among the two surfaces of the vane by the force equivalent to the force difference.

However, in such a conventional vane motor, since a plurality of vanes formed on the rotor reciprocates along the cam ring internal side surface, it may cause deterioration of rotational power generation efficiency due to wear of components and pressure leakage, and the power generation principle of the vane motor The force generated by the pressure of the fluid flowing between the vane and the vane is applied to the vane surface opposite to the direction of rotation of the rotor in comparison with the force generated by being applied to the vane surface in the direction of rotation of the rotor among the two surfaces of the vane The rotational force is generated by pushing out the vane surface of the vane opposite to the direction in which the rotor rotates in the two surfaces of the vane by the force of the force difference. The power difference is not large and the power generation efficiency is low. The rotor is too heavy and the power generation efficiency is low.

In addition, the inlet may be configured to reflect the pressure of the fluid applied from the inlet to the vane in the direction of rotation of the rotor, so that the vane may receive a stronger pressure of the fluid formed in the oil chamber.

On both sides of the cam ring, at least one of the two covers is bolted to the opposite side cover with the inflow passage formed therein.

A wheel-shaped rotor is disposed at the center of the cam ring, and the rotor is spline-coupled with the rotation shaft to transmit a rotational force to the rotation shaft.

In order to prevent leakage of the pressurized fluid, the wheel-shaped rotor is made of a rubber material such as natural rubber, synthetic rubber, nylon, Teflon, polyethylene, vinyl chloride And packed with an elastic packing material.

The outer peripheral surface of the rotor and the outer peripheral surface of the rotor contacted with the inner surface of the vane except for the inlet side surface of the vane and the outer peripheral surface packing portion of the rotor and the outer peripheral surface of the rotor contacting with the oil room forming body are made non- ≪ / RTI >
