1 Hovercraft Technology Taking Us Back to the Future (December 2015)

There are few things in this world that elicit such a gleeful, childlike sense of wonder as does the word “hoverboard”.

2 Guide to Selecting and Replacing Synchronous Belts (June 2016)

Just as we now consider rotary dial phones archaic, so are many installed synchronous belt drives. That they continue to operate is testimony to their durability. But that should not prevent you from taking advantage of newer synchronous belt drive technology that can improve both equipment design and field installations.

3 Timing Belts and Pulleys - Operations (December 2016)

Synchronous drives are especially well-suited for low-speed, high-torque applications. Their positive driving nature prevents potential slippage associated with V-belt drives, and even allows significantly greater torque carrying capability. Small pitch synchronous drives operating at speeds of 50 ft/min (0.25 m/s) or less are considered to be low-speed. Care should be taken in the drive selection process as stall and peak torques can sometimes be very high. While intermittent peak torques can often be carried by synchronous drives without special considerations, high cyclic peak torque loading should be carefully reviewed.

4 Guide to V-Belt Selection and Replacement (June 2017)

V-belts look like relatively benign and simple pieces of equipment. They're basically a glorified rubber band, right? Need a replacement? Just measure the top width and circumference, find another belt with the same dimensions, and slap it on the drive. There's only one problem: that approach is about as wrong as you can get.

5 Belts Vs. Couplings (August 2015)

rotary-type blowers? Examples: for motor KW; RPM; temperature; pressure production; lifetime; etc. In other words, how do I choose between belts or couplings?

6 The Automated Parking Garage (September 2014)

ContiTech and Wöhr Team up for Unique Residential Solution.

7 Improved Performance for Hydraulic Seals from Thermoplastic Polyurethane (June 2012)

Seal design engineers and end users are continually seeking improved sealing systems and materials. This paper describes the potential of a new thermoplastic polyurethane (TPU) material to deliver improvements in pressure, speed and temperature capability, which are presented as comparisons to proven industry standard materials. Performance is demonstrated by virtue of test bench results of seals made from MDI-, PPDI- and NDI-based materials.

8 Analyzing Synchronous Belt Failure (October 2009)

If you’re replacing your belts more than once per year, it’s time to analyze your drive. From belt crimping damage to high belt installation tension to sprocket misalignment and adverse environmental conditions, this guide walks you through how to identify the reasons behind premature failure and makes recommendations on corrective and preventive measures.

9 Total System Efficiency (February 2010)

Much of the industrial energy being consumed by systems is wasted through inefficiency. For this article, a system will be defined as the following components working together: electrical input power, variable frequency drives, induction motors, gearboxes and transmission elements (chains, belts, etc.).
