Abstract
The impact of fillet radius on spur gear performance made of metal matrix composite (Al-SiC MMC) made of silicon carbide. The improved mechanical qualities provided by the addition of silicon carbide particles to the aluminum matrix make this material appealing for gear applications. The study focuses on altering the fillet radius of spur gears in a methodical manner and examining the implications for important performance metrics like efficiency, fatigue life, and stress distribution. The most basic and popular type of gears for power gearbox are spur gears. It has become necessary in recent years to run machines at different loads and speeds. Typically, gear teeth break when a load exceeds a predetermined threshold. Thus, it is necessary to investigate alternative materials for the production of gears. The purpose of this study was to determine how fillet radius affected the metal matrix composite (MMC) spur gears made of aluminum and silicon carbide (Al-SiC). Ten commercially available gears with different fillet radii were examined for minimum lubrication film thickness, friction coefficients under various loads and speeds, and mechanical qualities (tensile strength and hardness). A spur gear made of aluminum silicon carbide metal matrix composite has a low density, a good strength-to-weight ratio, outstanding castability, and resistance to corrosion. The spur gear teeth's roots experience concentrated stress during operation, which causes cracks to begin to form and eventually cause the material to fail. In the current work, it is predicted different fillet radii affect the stress and strain at the spur gear root. The model used to estimate the design parameters at different fillet radii is constructed using analysis. This study illustrates the fillet radius affects the design parameters of a metal matrix composite composed of silicon carbide and aluminum to increase its strength.
