Gear Bending Stress Analysis of Automatic Transmissions with Different Fillet Curves

The Kinematic Design of Automatic Gear Transmissions for Bicycles

Recently, bicycles are used as exercising machines and traffic vehicles. Planetary gear trains can be used as the transmission systems for bicycles. The purpose of this work is to propose a design methodology for the kinematic design of automatic gear transmissions with planetary gear trains for bicycles. First, applying the check list method (combining and extending methods), the design concep...

Fundamental Development of Hypocycloidal Gear Transmissions

Torque Analysis of Magnetic Spur Gear with Different Configurations

This paper presents design and torque analysis in various types of magnetic gear with different magnetic materials and air gap. This type of gear offer both high speed and high torque required for drive applications. In the proposed gear analysis the low speed side is connected to prime mover and high speed side is connected to load, suitable for wind power, automobile applications and group dr...

Influence of Addendum Modification Factor on Root Stresses in Normal Contact Ratio Asymmetric Spur Gears

Tooth root crack is considered as one of the crucial causes of failure in the gearing system and it occurs at the tooth root due to an excessive bending stress developed in the root region. The modern power transmission gear drives demand high bending load capacity, increased contact load capacity, low weight, reduced noise and longer life. These subsequent conditions are satisfied by the aid o...

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...
