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,

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

Computer Aided Design of Internal Involute Spur Gears

14th Design Automation Conference, 1988
Abstract The modern theory of gearing provides principles of generation for conjugate gear tooth surfaces while computer aided design is a very powerful tool in designing a gear train with conjugate shaped tooth surfaces. It is possible to set up a mathematical model for internal involute spur gears if the theory of gearing and the ...

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

Internal involute spur gear pairs with improved efficiency

1998
Eliminating all toothing non-geometrical parameters from the formula for the calculation of the sliding mechanical power loss in the spur gear teeth mesh, the geometrical friction loss function has been got. The minimum of this function for a gear pair with fixed module, number of teeth and centre distance corresponds to the optimal addendum ...

BEARING CONTACT ANALYSIS OF THE INVOLUTE SPUR PLANETARY GEAR TRAIN

Transactions of the Canadian Society for Mechanical Engineering, 2001
The goal of this study is to determine the dimensions and orientations of instant contact ellipses of gear surfaces in the meshing of the planetary gear train in order to recommend the proper amount of the crowning radii. The mathematical model for the surface profiles of the simple planetary gear train with the crowned planet gear is developed to ...

Separation distance and static transmission error of involute spur gears

28th Joint Propulsion Conference and Exhibit, 1992
The effects of separation distance and deflection of gear teeth on the static transmission error of involute spur gears are investigated. In this paper, only low-contact-ratio gears with true involute profile are studied. Gear ratio and tooth addendum are varied to examine their effects on the separation distance and static transmission error.

3D Analysis of Involute Spur Gears

1998
The paper deals with the stress field in spur involute fillet investigated by means of finite element method. To take into account the actual three-dimensionality of the gear, three-dimensional models were used for the determination of the fillet tangential stress component and stress directed to a gaer axis.

Load Sharing Model for Non-standard Involute Spur Gears

2012
The presence of undercut at the tooth root, non-equal addendum on pinion and wheel, non-standard tooth height or non-standard center distance may have decisive influence on the load sharing between pairs of teeth in simultaneous contact of spur gears. The curve of variation of the meshing stiffness along the path of contact, quite symmetric respect the
