Abstract
The equidistant curve of the theoretical profile can be used as actual tooth profile, based on which a new type cosine rotator pump isolated by roller is proposed. The main advantage of the new pump is that only one pair of tooth works at one point, which avoids being trapped by oil. Besides, the friction between the contact surface changes from sliding to rolling, which largely reduces the friction force. The formula of instantaneous flow rate was derived then, accompanied with the method of calculation and modeling combination, the instantaneous flow rate of the new pump was illustrated to be approximately constant. On the basis of the analysis of the liquid pressure and the meshing force, the radial force can be effectively reduced by choosing proper width and top diameter of rotator, reducing cavity size and using hydraulic balance. As a result, it may provide theoretical support for accelerating the practical use of the pump.
