U.S. wind turbine growth puts a new spin on bearing manufacture.

Servo control system engineers typically work designing new systems or redesigning existing systems for conveyors, pick and place machines, gantries, machine tools or other equipment.

Th e Allen Telescope Array at Hat Creek, CA is a joint venture between the University of California Berkeley and the SETI Institute of Mountain View, CA. SETI has hired Minex Engineering of Antioch, CA to help with the design and installation of state-of-the-art drives and controls for the antenna array.

When rolling element or sleeve bearings operate under extreme conditions, it’s more important than ever to follow proper lubrication selection and maintenance procedures to maximize eff ective life and effi cient performance.

Some gear geometries are more practical to produce than others. Since choices made early in the design process aff ect the ease and cost of fabrication, those who design gears would do well to consider molding and how molders operate, especially when they create precision gears.

Readers of our sister publication, Gear Technology, are perhaps more familiar with the American Gear Manufacturers Association (AGMA) than our PTE audience. Now more than 90 years old, AGMA continues to thrive as a global, relevant go-to resource and service provider—from metrology to tribology—for its more than 400 worldwide members. PTE put some questions regarding AGMA—now, and going forward—to AGMA president Joe T. Franklin, Jr.

A little over 10 years ago, Louise O’Sullivan was serving as president of one of Dover Corp.’s myriad divisions. One of her duties in that role was to attend the bi-annual cattle calls, i.e.— corporate executive business meetings attended by approximately 22 Dover decision makers. Invariably, at some point in those meetings, someone would ask, “Since we all buy the same things, why don’t we pool our signifi cant purchasing power to achieve better pricing and service?”

Today’s newspaper advertisers demand vibrant, attractive color printing, and newspaper printers are constantly looking for methods to improve printing processes to meet these demands. When it comes to improving the printing process, the key component is to choose the right printing press.

Th e total U.S. electric motor base exceeds 100 million motors and consumes more than 50% of all electricity generated in the country. Small motors—fractional horsepower to 20-hp—comprise 99% of the motor population but consume only 25% of all generated electricity (Refs. 1,3,10,14).

When it comes to selecting a connecting element between a drive motor and a pump unit, engineers most often choose an elastomeric coupling because of its failure protection and its vibration damping capabilities. Elastomeric couplings, traditionally manufactured with metallic hubs, feature a rugged and robust design noted for its simplicity.
