Structural Analysis of Mini Power Weeder Worm and Worm Gear with Three Different Materials

The main aim of this paper is to conduct the structural analysis of min power weeder worm and worm gear with three different materials.The objectives of this paper are to calculate the design of worm and worm gear, to draw the model of worm and worm gear by using AutoCAD 2019 software, to analyze the structural behavior of worm and worm gear by theoretical approach using von-Mises criteria and compare with numerical structural result using ANSYS 16.2 software, and to select the suitable material of worm and worm gear for good performance.A 2.5 hp engine power and 6000 rpm worm speed mini power weeder is used in this paper to do worm and worm gear bending stress analysis with material properties of phosphor bronze, aluminum bronze, and tin bronze material.For the phosphor bronze material, the lowest von-Mises stress and effective strain are obtained.Thus, phosphor bronze is found to be the suitable material for worm and worm gear.
