The Torsional Stiffness of Involute Spur Planetary Gears

2015
This paper presents the results of torsional stiffness analysis of involute spur planetary gears in mesh using finite element methods. A planetary gear model with 3 planet gears and its subsystem models have been developed to study the relationship between the overall torsional stiffness and the subsystem torsional stiffness.

The Oil Condition Analysis of Involute Spur Gear

Applied Mechanics and Materials, 2012
A gear microscopic surface pitting lubrication model was established, and the oil condition of it was introduced. Based on the multi-grid method, a numerical solution of spur gear oil condition lubrication was obtained. The result show that with the provided oil film thickness increases, the film thickness of the meshing point also increases.

Non-stationary elastohydrodynamic lubrication analysis of an involute spur gear

Proceedings of 2011 International Conference on Electronic & Mechanical Engineering and Information Technology, 2011
Non-stationary elastohydrodynamic lubrication (EHL) of an involute spur gear is a very complex problem. A full transient EHL solution of an involute spur gear is obtained by utilizing the multigrid method, which takes the variation of equivalent curvature, entrainment velocity and load on time along the line of action into consideration.

Lubrication Characteristics of Involute Spur Gears: A Theoretical Investigation

Journal of Fluids Engineering, Transactions of the ASME, 1945
Abstract In this paper the lubricating-oil wedge which separates the tooth surfaces of involute straight spur gears is analyzed mathematically. Expressions are derived for the pressure distribution, the maximum pressuro, the minimum thickness, and the load-carrying capacity of the wedge for any phase of mating.

A general finite element model of involute gears

Finite Elements in Analysis and Design, 2004
Involute gears comprise primarily spur gears, helical gears, straight conical involute gears and conical involute gears. Robust and effective parameterised finite element models of involute gears should be based on analytically derived mathematical ...

Parametric analysis of asymmetric involute spur gear tooth

International Journal of Powertrains, 2019
The focus of this work is a geometric parameter of an asymmetric involute spur gear tooth. Gear strength is influenced by tooth geometry. So, knowledge of tooth geometric is required which will help to improve the strength of a gear tooth. In this article, a data generated from an equations and presented in form of graph for better interpretation of ...

Effect of Involute Contact Ratio on Spur Gear Dynamics

Journal of Mechanical Design, 1999
The influence of involute contact ratio on the torsional vibration behavior of a spur gear pair is investigated experimentally by measuring the dynamic transmission error of several gear pairs using a specially designed gear test rig. Measured forced response curves are presented, and harmonic amplitudes of dynamic transmission error are compared above

Parametric Modeling of Involute Spur Gear Based on AutoCAD

Advanced Materials Research, 2014
This paper, taking the involute spur gear as a research object and using the LISP module embedded in AutoCAD, studies how to realize the drawing of two-dimensional graphics of the involute tooth profile and keyway of spur gear effectively and efficiently. The study, using the commands, such as stretch and Boolean operation of AutoCAD after programming,

Dynamic analysis of involute spur gears with asymmetric teeth

International Journal of Mechanical Sciences, 2008
Abstract New gear designs are needed because of the increasing performance requirements, such as high load capacity, high endurance, low cost, long life, and high speed. In some applications, such as in wind turbines, the gears experience only uni-directional loading. In these instances, the geometry of the drive side does not have to be symmetric to
