Gear failure is considered the main alarming and undesirable event in gearboxes. Usually, cracks happen by fatigue caused due to cyclic loading. Fatigue stress focused on teeth root because of small tooth fillet radius. This causes progressive damage gear which failure, hence, a damaged gear. work shows numerical framework identify quantify cracks' existence at spur gears. The problem numerical...

Power losses in gearboxes result frictional heating. Sufficient heat transfer from the gearbox to environment is required for reliable operation. The dissipation gears linked their interaction with fluids gearbox. Recent research has demonstrated use of Computational Fluid Dynamics (CFD) predict fluid flow and no-load an isothermal manner. This study focuses on a numerical analysis within dry-l...

Involute spur gears are key machine elements for power transmission in various industrial sectors. During transmission, the teeth subjected to high stresses. Many design modifications used reduce these stresses, such as increasing drive side pressure angle and profile shifting factor. These change contact ratio center distance of gear pair. Changing tooth thickness is another solution stress. B...

Gear assembly errors are an important contributor to a premature gearbox failure. This study investigates the effects of center distance deviation on polymer life. The main focus was influence stress state gear. Reference spur gears (m = 1 mm, z 20, b 6 mm) with standard involute gear profile and ratio (same pinion gear) were studied. A combination numerical experimental methods used obtain bes...

Gear tooth spalling is one of the inevitable fault modes in long-term service traction transmission system railway vehicles, which can worsen dynamic load rotating mechanical and reduce operating quality. Therefore, it necessary to study its mechanism guide diagnosis scientifically. This paper established a planar vehicle model with an analytical time-varying meshing stiffness (TVMS) spur gear....

During the design process, a designer transforms an abstract functional description for a device into a physical description that satisfies the functional requirements. In this sense, design is a transformation from the functional domain to the physical domain; however, this transformation process is not well characterized nor understood for mechanical systems. The difficulty arises, at least i...
