The kinematic and dynamic analysis of crowned spur gear drive Original Research Article

The authors have proposed modification (crowning) of geometry of spur gears and investigated the contact pattern and the transmission errors to recommend the appropriate amount of crowning. Based on the investigation, dynamic load of the crowned spur gear drive has been calculated which is helpful to predict the life of the designed gear drive. Computer programs for simulation of meshing and dynamics of the crowned spur gears have been developed. The developed theory is illustrated with numerical examples.
