Tech Tip: How to keep heavy loads balanced

Some Thomson smart linear actuators have a position-based synchro-nization option to help manage unbalanced loads when using multiple units. The system adjusts the speed of each actuator to keep them starting, moving, and stopping synchronously, regardless of their respective load distribution. So useful. So smart.

Best high-speed rotary bearing in THK history

THK has developed its best-performing, high-speed rotary bearing ever: the High-Speed, Double-Row Angular Contact Ring BWH. This rotary bearing has balls aligned inside a cage between the inner and outer rings and is part of the THK Rotary Series, along with the cross-roller ring. The main features of this product are its ability to receive loads in all directions as well as its high rigidity and rotational accuracy, which are equal to that of cross-roller rings. By adopting a new structure to change the rolling elements from rollers to balls, this product achieves the greatest high-speed performance ever offered by THK.

What are non-captive linear actuators?

According to PBC Linear, their new non-captive linear actuators are different from the more common external versions of lead screw-driven linear actuators because they allow the lead screw to completely pass through the motor. This fundamental difference offers advantages for designs that have limited space available or for engineers looking to shrink the overall size of their design package.

Natural gas/gasoline bi-fuel Chevrolet Impala sedan in the works

General Motors will build a Chevrolet Impala sedan for retail and fleet customers that operates on either gasoline or compressed natural gas, (CNG), GMC Chairman and CEO Dan Akerson announced October 16.

It is the only manufacturer-produced full-size bi-fuel sedan, and it is expected to go on sale next summer as a 2015 model. Akerson announced the car during remarks at an energy summit marking the 40th anniversary of the OPEC Oil Embargo.

"OPEC Oil Embargo + 40: A National Summit on Energy Security" was sponsored by the nonpartisan group Securing America's Future Energy, or SAFE. Prominent political, business, and military leaders assessed the current state of America's oil dependence since the 1973 oil embargo.

Akerson said the bi-fuel Impala is an example of using affordable technology to reduce oil consumption and save consumers money at the pump.

"We know that U.S. energy security won't come from a one-off moonshot," Akerson said. "It will flow from our systematic investment in technology and innovation ... our drive to get more from existing energy sources and renewables ... our commitment to conservation ... and it will be assured by fully and safely exploiting our shale gas reserves."

Natural gas is a cleaner-burning transportation fuel compared to petroleum products and costs significantly less than gasoline at current prices. CNG vehicles typically have 20 percent fewer greenhouse gas emissions than gasoline-powered cars, according to the California Air Resources Board.

The Chevrolet Impala bi-fuel sedan addresses the range anxiety issue associated with vehicles that run only on natural gas, Akerson said. It features a factory-engineered and fully warranted powertrain that switches seamlessly from CNG to gasoline. Total range is expected to be up to 500 miles.

Akerson said that, in addition to advanced technologies and alternative fuels, achieving energy security will require productive partnerships between energy companies, utilities, environmental groups, labor unions, universities, and manufacturers.

GM, he said, is working closely with 14 of the country's largest unions and environmental groups through the Blue-Green Alliance and has relationships with regulators that are "more constructive than ever."

Akerson also reiterated a call he made earlier this year for the current administration and Congress to create a new, consumer-driven national energy policy from a position of strength and abundance.

For its part, GM has issued statements saying that it is committed to saving 12 billion gallons of gasoline in its 2011 to 2017 model-year vehicles -- offsetting nearly a year of crude imports from the Persian Gulf -- with technologies that include lighter materials to reduce vehicle mass, alternative fuels, clean diesel, and electrification.

In addition to the Chevrolet Volt, Chevrolet Spark EV, and the upcoming Cadillac ELR, GM is introducing start-stop technology standard on the 2014 Chevrolet Malibu, helping the midsize sedan achieve 25 mpg city/36 mpg highway, and using electrification to boost fuel economy in the Buick Regal and LaCrosse sedans, which both get EPA-estimated 36 mpg hwy.
