On custom jobs, consider Direct Gear Design—an application-driven gear development process with primary emphasis on performance maximization and cost efficiency.
In this article you'll learn about a fillet profile optimization technique that allows for substantial bending stress reduction, producing a variety of gear performance benefits.
Harnessing Direct Gear Design for asymmetric gears results in low weight-to-output torque ratio and reduced levels of noise and vibration.
Self-locking gears prevent backdriving and inertial driving, and they may find applications in a wide variety of industries.
Research and development of asymmetric tooth spur gears for modernization of the light multipurpose helicopter gearbox has amplified its load capacity to utilize more powerful turboshaft engines.
By presenting spiral face gears with an involute tooth line and an identical tooth profile in the normal section at any given radius, two applications are made possible for such face gears.
Direct Gear Design, a development process where gear parameters are primary and tool parameters are secondary, maximizes performance of plastic gearing by compensating for polymer property limitations.
Following the Direct Gear Design approach to asymmetric epicyclic gear stages with singular and compound planet gears, methods of optimization of the tooth flank asymmetry factor and root fillet profile are considered.
Pitch factor analysis is an analytical tool that can be used for comparison of different gear geometry solutions by exploring the characteristics of involute gear mesh parameters that define gear drive performance.
Price and the ability to offer a much larger design window are making manufacturers look to powder metal gears as a solution for high-performance gears.
This paper provides an analysis of the benefits of optimizing the tooth root fillet of thin rim planet gears with asymmetric teeth.
