ANALYSIS OF MECHANICAL PROPERTIES OF HELICAL GEARS

Gear is the important member for transmission of power. Different types of gears are used for this power transmission, and helical gears are used in power transmission of Permanent Magnet DC Motors. The main reason for the failure of the gears are bending and surface strength, thus the analysis of these parameters become the most popular filed of interest for the researchers to minimize this failure. In aim of this paper is to different types of stresses occurring in the helical gears of permanent magnet DC motor with analytical solutions as well as FEM solution with the help of ANSYS 14.0. The modeling of the helical gear sets is done by using the modeling software CATIA V5 R20.The different types of stresses were found out by using ANSYS 14.0 software. The stress of the gears is analyzed for different materials like aluminum, structural steel, and steel EN 19 and results are compared. The analysis can be further extended for different types of gears such as spur, bevel, rack and pinion, etc... By varying different parameters like face width, gear ratio and many more parameters. https://journalnx.com/journal-article/2015023
