That old “Overhead” article reminded me of what a shock it was when we first moved into cellular manufacturing. After years of investigating ways t...

Comprehensive descriptions of what you will find in the booths of many leading gear industry suppliers at IMTS 2016.

Plastic gears are everywhere today - throughout your car, at the oceans' lowest depths, in deep space. The question, when is a metal gear a candidate for plastic conversion, can be addressed in three words, i.e. what's the application?

At the dawn of the Industrial Revolution, so-called mechanics were tasked with devising the precise methods that would make mass production possible. The result was the first generation of machine tools, which in turn required improved tooling and production methods.

Why is there so much emphasis on the tooth contact pattern for bevel gears in the assembled condition and not so for cylindrical gears, etc?

While external involute gears are very tolerant of center distance variations, what are the center distance constraints for internal gears?

Micropitting, pitting and wear are typical gear failure modes that can occur on the flanks of slowly operated and highly stressed internal gears. However, the calculation methods for the flank load-carrying capacity have mainly been established on the basis of experimental investigations of external gears. This paper describes the design and functionality of the newly developed test rigs for internal gears and shows basic results of the theoretical studies. It furthermore presents basic examples of experimental test results.

New precision internal gears from Sterling Instrument are available from stock in inch and metric sizes. The 20? pressure angle inch ...

With the aim of reducing the operating noise and vibration of planetary gear sets used in automatic transmissions, a meshing phase difference was applied to the planet gears that mesh with the sun and ring gears.

Atlanta GmbH in Bietingheim-Bissingen, Germany, announced the formation of its new North American subsidiary, Atlanta Drive Systems Inc.,...
