Design and performance experiments of elliptical gears in elliptical gear flowmeter

In the design process of elliptical gear flowmeter, the design of elliptical gear pair is crucial. The problems to be solved are mainly the design of the second-order elliptic pitch curve and the design of the gear tooth profile. In this paper, the elliptical gear is theoretically analysed, a new design idea is provided, and the design of the second-order elliptic pitch curve is achieved by using MATLAB as the programming calculation programming tool, and the tooth profile of the elliptical gear is trimmed by using KISSsoft. The strength analysis of the elliptical gear is carried out through simulation experiments, and the good meshing of the elliptical gear pair is verified by using the accuracy test of the flowmeter. The rationality and feasibility of the design idea are finally confirmed.
