Abstract

The gear mechanism is part of the power transmission system that transmits motion from one shaft to another. Recent studies have focused on tuning the different design parameters. As a result of these studies, the equipment's performance, strength and reliability are being improved. The bending stress of spur gears and the tangential load capacity are analyzed by numerical simulation using microbial multicomponent gas bubbles and the shear force activation concept. Using SolidWorks Simulation and AGMA criteria, various gear shapes were tested under continuously loaded conditions. Improving load-carrying capacity and reducing bending stress in gear teeth can be achieved by increasing the pressure angle and the face width. The tooth face width is increased to reduce the load on the tooth. Increasing the pressure angle will not affect the tooth's stiffness, but it will increase the principal stress. Future gears will be more effective and last longer as a result of this research.
