In July, Design News ran a paragraph in their FLASH section, which denotes
new and notable product designs. The article highlighted how the ST1W
electromagnetic clutch allowed a go kart to achieve speeds in excess of 100
mph.
Machine Design ran an editorial in their August 7 edition on how Ogura's clutches are being used in the oil field industry to allow natural gas engines to cost effectively replace electric motors on pump jacks and how ideally they are suited for continuous exposed environmental conditions.
This news article from the August 5th edition of Machine Design shows Ogura PTO clutches on a new type of remote control mower.
In December and article in Hydraulics and Pneumatics discussed how Ogura pump clutches can be used to decrease pump wear and fuel efficiency in both mobile and stationary applications.
In March of 2007 Diesel Progress ran an editorial describing how Ogura's high efficiency superchargers helped Kawasaki jet skis and other manufacturers achieve higher horse power output. The article also describes how by utilizing Ogura electromagnetic clutches superchargers can be engaged and disengaged only when needed to reduce parasitic loads.
In April 2008 Diesel Progress ran an article about Ogura's advantages for the supercharger when used with marine engines.
The original article for this story appeared in some industry newsletters in 2006. The attached story is the full article that appeared in Power Transmission Engineering magazine. The article describes how Ogura brakes are being used to help position radio telescopes as they search for intelligent life in the universe.
In the December 11th issue of Machine Design an article, In the Reporters Notebook section, talked about how the Ogura Spring Applied Brakes help the Action-Cam Company control their high definition stadium camera. The link above shows the article as it appeared in the Ogura Newsletter. If you would like to see the Machine Design article please visit www.machinedesign.com.
There is a typo in the low speed formula. The reflected inertia of LG1 is currently listed as JLG1/(NS2/NL1)2. The correct formula should be JLG1/(NL1/NS2)2. In the high speed operation the reflected inertia of large gear 2 and small gear 1 is repeated twice. JLG2 + (JLG1/(NL1/NS2)2) should be eliminated from the first half of the equation.
These mistakes were caught by Neal Middleberg, who is the Chief Engineer of Bowe Bell and Howell, who uses this type of formula to help define total system inertia in complex machines.
On July 9th, Machine Design published an article written by Ogura on considerations that design engineers should follow when designing in electromagnetic clutches and brakes. The original article that was submitted is attached as well as the link to the article in Machine Design.
