8 Baby Steps in Wind Energy (August 2015)

The Department of Energy estimates that 4 million megawatts of potential power—four times the amount all U.S. power plants combined currently produce—exists in offshore wind energy. Construction of America’s first offshore wind turbines began in July. The wind farm, which is being constructed off the coast of Block Island, RI, will consist of five turbines. Together, they will produce 30 MW.

9 Thrust Cone Bearings Provide Increased Efficiency for Helical Gear Units at Moderate Speed Levels (June 2018)

Thrust cone bearings are an elegant option to handle the axial forces generated by the torque transmission in helical-toothed gear stages. They have proven as an efficient and reliable bearing concept for integrally geared compressors but are nearly unknown in other fields of gearbox engineering. The presented investigations consider three aspects which appear relevant to extend the field of possible applications for thrust cones towards gearboxes constructed with roller bearings.

10 Precision Bellows Couplings (March 2015)

Bellows couplings first began to be widely used by machine tool builders in the mid-to-late 20th century. With the advent of CNC technology, machine engineers started looking to improve upon some of the negative influences traditional power transmission couplings can have on a precision rotary / linear motion system.

11 Simulation Software Provides a Different Set of Tools for Motor Efficiency (June 2018)

While some organizations focus on real-world analytics and data collection for predictive maintenance, simulation tools and virtual prototyping can be another solution for motor efficiency.

12 Metal-to-Plastic Conversion Parts Help Drive Heavy Industry (February 2018)

While metal-to-plastic parts conversion actually began way back in the Fabulous Fifties, think toys, household products, etc., it is only in more recent years that plastic conversion has gained a firm foothold in the more strength- and lifetime-demanding applications such as aerospace, under-the-hood automotive, motors, valves, bearings and, as they say, much more.

13 Hydraulics & Pneumatics Assessment (April 2012)

The National Fluid Power Association (NFPA) is an organization consisting of manufacturers, distributors, suppliers and educators working together to strengthen the fluid power market. Its mission is to serve as a forum where all fluid power channel partners can advance fluid power technology and successfully compete in the global industrial market.

14 Nine Manufacturing Trade Shows Under One Roof (August 2008)

Industry leaders will gather to showcase their latest technologies September 23–25, in Rosemont, IL. Presented by trade show organizer Canon Communications, National Manufacturing Week comprises nine manufacturing shows.

15 Quiet Out There - Global Industrial Outlook (August 2013)

Since our last appearance in this space we've attended the Paris Air Show and met with companies involved in oil production, hydraulic fracturing and wind turbine towers and components. As an investment analyst I am always seeking to help my clients anticipate change in order to manage risk and capture alpha (positive returns relative to market). But as a regular columnist for Power Transmission Engineering, I also seek insights that can help your organization do the same. Here is what we've found...

16 Turning Brownfields Green (April 2009)

The new energy economy is making some headway in the manufacturing community. Organizations are coming up with creative strategies to convert old industrial plants into green manufacturing hubs or simply cost-effective renovation projects. It’s another sign that the country is taking sustainability and environmental awareness seriously.

17 Sensing the Motion: Rotary Position Sensors (August 2010)

This paper provides an overview of the more common position sensor options and references actual case studies to illustrate the diverse solutions available and the reasons behind some of the decisions. Three cases are used to illustrate the needs of different applications leading to the choice of a particular type of position sensor. The cases reviewed include a gantry crane, wind turbine and aerial cable car.
