PURPOSE: An oil pump is provided to have simple structure and reduce noise by performing the dynamic transfer function and pumping function of the oil pump through one helical structure. CONSTITUTION: An oil pump comprises an oil inlet part, the oil outlet part, a oil pump body(1), a driving shaft(2), a driving gear(4), a driven gear(5), and a driven shaft(3). The oil inlet part is formed at one side. The oil outlet part is formed at the other side. In the oil pump body, the space for the movement of the oil is formed inside. The driving shaft is mounted on the body to rotate in the space for the movement of the oil. The driving gear is formed at the one end of the driving shaft. The driven gear engages with the driving gear and injects the oil to the space for the movement of the oil. The driven gear transfers the injected oil to the oil outlet part and the compresses the oil. The driven shaft is coupled on the center of the driven gear and becomes a shaft for the rotational motion of the driven gear. The driving gear and the driven gear move the oil which flows into the space for the movement of the oil to the oil outlet part.
