AGMA Promises Bigger, Better Show in Detroit
AGMA's Gear Expo '93 is expected to be at least 10% larger in terms of floor space than the '91 show, according to Joe Franklin, AGMA's executive director. "As of June 1, we have 80 exhibitors registered", he says.
Gear Expo '93 Promises To Be The Biggest All-Gearing Trade Show Yet
Gear Expo '93, "The World of Gearing," is scheduled for October 10-13 at Cobo Conference & Exhibition Center, Detroit, MI. Hours are 9 a.m. to 5 p.m. on all four days of the show.
The European Rack Shift Coefficient 'X' for Americans
The use of dimensionless factors to describe gear tooth geometry seems to have a strong appeal to gear engineers. The stress factors I and J, for instance, are well established in AGMA literature. The use of the rack shift coefficient "x" to describe nonstandard gear proportions is common in Europe, but is not as commonly used in the United States. When it is encountered in the European literature or in the operating manuals for imported machine tools, it can be a source of confusion to the American engineer.
CNC Bevel Gear Generators and Flared Cup Gear Grinding
New freedom of motion available with CNC generators make possible improving tooth contact on bevel and hypoid gears. Mechanical machines by their nature are inflexible and require a special mechanism for every desired motion. These mechanisms are generally exotic and expensive. As a result, it was not until the introduction of CNC generators that engineers started exploring motion possibilities and their effect on tooth contact.
Contact Analysis of Gears Using a Combined Finite Element and Surface Integral Method
The complete and accurate solution t the contact problem of three-dimensional gears has been, for the past several decades, one of the more sought after, albeit elusive goals in the engineering community. Even the arrival on the scene in the mid-seventies of finite element techniques failed to produce the solution to any but the most simple gear contact problems.
Gear Expo '93 - A Wise Investment (Publishers Page)
Gear Expo '93 - another trade show, another plea to send people and/or equipment out of town, away from the office or plant. Another bid to spend time, money, and effort. Oh, please! Hasn't anybody heard that these are the "lean and mean" '90s?
Gear Tip Chamfer and Gear Noise; Surface Measurement of Spiral Bevel Gear Teeth (Q&A)
Could the tip chamfer that manufacturing people usually use on the tips of gear teeth be the cause of vibration in the gear set? The set in question is spur, of 2.25 DP, with 20 degrees pressure angle. The pinion has 14 teeth and the mating gear, 63 teeth. The pinion turns at 535 rpm maximum. Could a chamfer a little over 1/64" cause a vibration problem?

Money Business: Exporting - Part III (Management Matters)
The object of any business transaction, be it foreign or domestic, is making a profit. That's why you go through all the effort of making and selling your product in the first place. Getting paid in a timely manner is crucial to making profit, but when your customer is in another country, this "timely and convenient" payment can become complicated; hence, your need for a banker with expertise in international markets.
