Nonlinear Dynamic Analysis of a Spur Gear Pair System with Wear Considering the Meshing Position

Lubricants
In this paper, a nonlinear dynamic model of a parallel shaft gear system consisting of two involute spur gears is developed to investigate the coupling effect between the gradual surface wear of gear teeth over time and nonlinear dynamic characteristics.

Dynamic analysis of spur gears using computer program DANST [PDF]

DANST is a computer program for static and dynamic analysis of spur gear systems. The program can be used for parametric studies to predict the effect on dynamic load and tooth bending stress of spur gears due to operating speed, torque, stiffness ...

Analysis of Energy Efficiency in Spur Gear Transmissions: Cycloidal Versus Involute Profiles

Machines
The involute profile is used almost exclusively in the manufacturing of spur gears. Nevertheless, in machinery design, the evaluation of environmental factors, such as energy efficiency, has become increasingly important when choosing between feasible ...

Reduction of gear pair transmission error with tooth profile modification [PDF]

, 2008
The gear noise problem that widely occurs in power transmission systems is typically characterised by one or more high amplitude acoustic signals. The noise originates from the vibration of the gear pair system caused by transmission error excitation ...

Generation of a crowned pinion tooth surface by a surface of revolution [PDF]

A method of generating crowned pinion tooth surfaces using a surface of revolution is developed. The crowned pinion meshes with a regular involute gear and has a prescribed parabolic type of transmission errors when the gears operate in the aligned mode.

Analysis on inverse method for design parameters of involute spur gears with unilateral tooth profile wear

Jixie chuandong
ObjectiveThe failure of transmission gears in imported and aged equipment due to tooth flank wear often leads to premature scrapping of the entire machine, as original design data is frequently unavailable for repair or replacement. To address this issue,

Gearing [PDF]

Gearing technology in its modern form has a history of only 100 years. However, the earliest form of gearing can probably be traced back to fourth century B.C. Greece. Current gear practice and recent advances in the technology are drawn together.
