Study on Tooth Profile of Involute Conjugated Internal Gear for High-Pressure Internal Gear Pumps

Abstract:

Article Preview

Conjugated internal gear is the key component of high-pressure internal gear pumps, which decides the performance of the pumps, such like volumetric efficiency, capacity of fluid discharge, wear life, flow pulse, vibration and noise. In this paper, a method of generating tooth profiles for conjugated internal gear is presented. Based on gear geometry and meshing theory, the parametric equations of involute conjugated internal gear are derived. With the help of MATLAB and SolidWorks, 3D models of the gear couple are built to evaluate the feasibility of the method.
