Modelling windage power loss from an enclosed spur gear

Expert System Development for Spur Gear Design

Expert systems have experienced tremendous growth and popularity since their commercial introduction in the early 1980’s. Today, expert systems are used in business, science, engineering, manufacturing, medical diagnosing, chemical, and many other fields. Mechanical engineers are the major users, expert systems, are finding rapid application in industry for such tasks as analysis of quality con...

Spur Gear Design via Particle Swarm

This study aims to employ a nature inspired algorithm Particle Swarm (PS) to seek minimum center distance for desired life of a compact spur gear set to tranulsmit a given power satisfying a number of constraints imposed. The PS, which is relatively recent heuristic search technique, imitates social behavior of birds flocking by sharing information among their members in multiple dimensions in ...

An Experimental Study of Windage due to Rotating and Static Bolts in an Enclosed Rotor-Stator System

Spur Gear Tooth Stress Analysis And Stress Reduction

Gears are commonly used for transmitting power. They develop high stress concentration at the root and the point of contact. The repeated stressing on the fillets causes the fatigue failure of gear tooth. The main objective of this study is to add different shaped holes to reduce stress concentration. A finite element model of Spur gear with a segment of three teeth is considered for analysis a...

A Transient Mixed Elastohydrodynamic Lubrication Model for Spur Gear Pairs

In this study, a transient, non-Newtonian, mixed elastohydrodynamic lubrication (EHL) model of involute spur gear tooth contacts is proposed. Unlike the contact between two cylindrical rollers, spur gear contacts experience a number of time-varying contact parameters including the normal load, radii of curvature, surface velocities, and slide-toroll ratio. The proposed EHL model is designed to ...
