October is the time. Detroit is the place. AGMA Gear Expo '91 is the event. Cobo Center in downtown Detroit is where you will want to be in October if you have any interest in gear products, manufacturing, or research.
AGMA's Gear Expo '91, "The World of Gearing," opens Oct. 20-23 at Cobo Conference & Exhibition Center, Detroit, MI. Gear Expo '91 will provide 35,000 square feet of exhibits by 91 companies from around the world.
This method of testing large gearboxes or, indeed, any power transmission element, had numerous advantages and offers the possibility of large savings in time, energy, and plant, if the overall situation is conducive to its use. This usually requires that several such units need to be tested, and that they can be conveniently connected to each to each other in such a way as to form a closed-loop drive train. No power sink is required, and the drive input system has only to make up power losses. The level of circulating power is controlled by the torque, which is applied statically during rotation, and the drive speed. Principles, advantage, and limitations are described, together with recent experiences in the only known large-scale usage of this technique in Australia.
The finished gear engineer, the man who is prepared for all emergencies, must first of all know the basic design principles.
Next he must be well versed in all sorts of calculations which come under the heading of "involute trigonometry."
Today, as part of filling a typical gear hobbing or shaping machine order, engineers are required to perform an SPC acceptance test. This SPC test, while it is contractually necessary for machine acceptance, is not a machine acceptance test. It is a process capability test. It is an acceptance of the machine, cutting tool, workholding fixture, and workpiece as integrated on the cutting machine, using a gear measuring machine, with its work arbor and evaluation software, to measure the acceptance elements of the workpiece.
Re: Your editorial and "Viewpoint" by Joe Arvin.
Both you and Mr. Arvin make some valid points. Your editorial appears to be a response to Mr. Arvin's "Viewpoint." This is a response to both
Dictatorships can be stifling. In an autocratic organization, employees seldom participate in decisions that affect them. By establishing a collaborative environment, you allow everyone to play a role in making your organization a success.
