Meshing Stiffness Calculation and Analysis of the Cycloidal Pump’s Rotor
Tianjin University of Science & Technology, Tianjin, China
In order to calculate the meshing stiffness of the cycloidal pump’s rotor, a method of relationship that deduces two generating curtate epicycloid is proposed, the radius values of the inner rotor’s actual tooth profile curvature was calculated and analyzed; Based on the formula of Hertz, the cycloidal pump rotor’s meshing stiffness calculation formula is inferred, the changing curve of cycloidal pump rotor’s meshing stiffness is made, some important parameters on its meshing stiffness are studied, the maximum value of meshing stiffness is when the outer rotor mesh with inner rotor’s outer convex profile curve, and the minimum value is when the outer rotor mesh with the center of inner rotor’s inner concave.
