2001: A (Cyber) Space Odyssey

January 1, 2001

In 1968, Stanley Kubrick released the film 2001: A Space Odyssey, based on the story by Arthur C. Clarke. Back then, 2001 was a long way off. It was the future, a time of unknown marvels, amazing discoveries and technological achievements. Now we're in 2001. But while Clarke's and Kubrick's visions of 2001 took place in outer space, what captures my imagination this year is cyberspace.

Water Powered Machinery

January 1, 2001

In one of my many visits to northern New York state, which included the St. Lawrence River (Thousand Islands Region) and the Adirondack Mountains, I visited Croghan, a village on the Beaver River, which is fed by the Stillwater Resevoir in the Adirondack Mountains. At the base of a dam within the village, I found the remnants of a water turbine and a bevel gear drive system. Having worked for The Gleason Works for many years, I was intrigued by the remains of the bevel gears, which appeared to have had wooden teeth at one time.

Suitability of High Density Powder Metal Gears for Gear Applications

January 1, 2001

The implementation of powder metal (PM)components in automotive applications increases continuously, in particular for more highly loaded gear components like synchromesh mechanisms. Porosity and frequently inadequate material properties of PM materials currently rule out PM for automobile gears that are subject to high loads. By increasing the density of the sintered gears, the mechanical properties are improved. New and optimized materials designed to allow the production of high-density PM gears by single sintering may change the situation in the future.

Robotic Automated Deburring of Aerospace Gears

January 1, 2001

This report presents some interim results from an ongoing project being performed by INFAC, the Instrumented Factory for Gears. The purposes of this initial phase of the project were to demonstrate the feasibility of robotic automated deburring of aerospace gears, and to develop a research agenda for future work in that area.

Special Gears Help Hatch a Summer Movie

January 1, 2001

Chicken Run - the summer that used stop-motion clay figures - is about a group of chickens laying a plan to escape from their farm before they're turned into chicken pies. Distributed by Steven Spielberg's Dream Works, Chicken Run is also about a group of specially-made worms and wheels.

The Basics of Spiral Bevel Gears

January 1, 2001

This article also appears as Chapter 1 in the Gleason Corporation publication "Advanced Bevel Gear Technology." Gearing Principles in Cylindrical and Straight Bevel Gears The purpose of gears is to transmit motion and torque from one shaft to another. That transmission normally has to occur with a constant ratio, the lowest possible disturbances and the highest possible efficiency. Tooth profile, length and shape are derived from those requirements.
