News from around the Industry
America suffers $4.4 billion in losses due to earthquakes every year. While that's a drop in the bucket for our $16 trillion plus GDP, it's still a substantial amount of money, and some people are working to lessen those losses. One group is Earthquake Protection Systems (EPS), a company that is designing bearings to better protect buildings from earthquake damage.

When software goes bad, what do we call it? System failure? Human failure? A virus? A number of words will work. How about this? Glitch. It has that onomatopoeic quality that fairly screams, Downtime! And with good reason -- software-generated miscalculations can have very expensive -- if not perilous -- repercussions.
When it comes to gear design software, the learning curve never ends. The leading vendors offer various training programs to keep their users well-informed.
With the constant push for sustainable and environmentally friendly procedures on Earth, you'd think weâ™d apply the same rules high above it.

If youâ™re an electrical engineer you know how an electric motor works; if you arenâ™t, it can be extremely confusing. Therefore, hereâ™s the simplified explanation (or the âœhow an electric motor works for dummiesâ version) of how a four-pole, three-phase AC induction motor works in a car.
A thermo-mechanical model of a splash lubricated one-stage gear unit is presented. This system corresponds to a first step towards the design of a hybrid vehicle gearbox that can operate up to 40,000 rpm on its primary shaft. The numerical model is based on the thermal network method and takes into account power losses due to teeth friction, rolling-elements bearings and oil churning. Some calculations underline that oil churning causes a high amount of power loss. A simple method to reduce this source of power losses is presented, and its influence on the gear unit efficiency and its thermal capacity is computed.
The automotive industry is on the precipice of a shift. Here's what the future looks like and what you need to know to prepare for it.
CTI Symposium USA Examines North American Transmission Market Strategies
In the design of an automatic transmission gearbox, the variation of one parameter can result in different system performances due to the strong interdependencies among all components. For given transmission ratios, component lifetimes and safeties, or space restrictions, improvements in efficiency, noise, and weight can be achieved.
Experts gathered at the 9th CTI Symposium to discuss the challenges of reducing noise, improving energy efficiency and meeting the changing demands of the marketplace
In recent years the estimation of gearbox power loss is attracting more interest â” especially in the wind turbine and automotive gearbox industry â” but also in industrial gearboxes where heat dissipation is a consideration as well. As new transmissions concepts are being researched to meet both ecological and commercial demands, a quick and reliable estimation of overall efficiency becomes inevitable in designing the optimal gearbox.
The 8th International CTI Symposium on Automotive Transmissions, HEV and EV Drives took place in Rochester, Michigan from May 12-15. The event kicked off with its popular introductory seminar "Basics and Practice of Automotive Transmissions."
Today, better fuel economy is a main objective in the automotive development process. It remains top-of-mind with the auto industry and consumers because of costs and environmental impacts. Because the industry’s average fuel-economy standard is required to increase by 40 percent by 2020, manufacturers and engineers are working to develop fuel-efficient, environmentally friendly and reliable designs for vehicles.
What are the applications for net-forged gears. Are they used outside automotive differentials?
Following is a presentation of a gear design based upon a theoretically perfect gear technology, for which an overview is offered for consideration. What follows is a report on the design's testing and subsequent manufacture of a hypoid gear pair for a 1999 Ford Mustang.
Weiss North America, Inc. of Willoughby, OH has designed and produced rotary tables and other components for the automation industry for more than 45 years. When approached by Alpha Integration, Inc. of Murfreesboro, TN, a manufacturer of turnkey automated assembly, vision and testing systems, to provide a reliable turnkey solution for their 6-foot-tall automotive parts assembly machine, Weiss â˜tiered-upâ™ an innovative chassis and indexing table system solution.

The automotive world faces a tremendous change. Autonomous driving and electrification are two big topics in this context that are pushing this change. The demand for higher comfort, higher safety and tightened environmental requirements drive as well the technological change from former mechanical actuations to electro-mechanical systems in new vehicles. This can be observed especially for braking and steering systems.
Key technical drivers which can be addressed by advanced PM manufacturing technologies are, for example, the need for system downsizing in transmissions and differentials, the need for developing systems with higher power density and the strong NVH (Noise Vibration Harshness) requirements - especially for electrified transmissions or e-axle solutions.
The automotive industry is shifting for everyone, bearings manufacturers included. Here's what you need to know to make sure you're shifting with it.
Yes, the headline is correct: Autonomous vehicles are not a new idea. In fact, in the 1950s, handsfree driving so interested General Motors engineers that they designed a concept car for it. And in 1956, at its own auto show, the GM Motorama, the automaker unveiled the car, the Firebird II.
In the late 1940s, the U.S. auto industry started an exciting experiment and spent decades on it. One result came in '63, when the Turbine was introduced by Chrysler Corp., now a part of Fiat Chrysler Automobiles (FCA). In appearance, the two-door, four-passenger car looked like a regular car, but it wasnââ‚¬â„¢t. Under its sleek shell, the car had a jet engine.
In this paper, the models for different power loss sources in transmissions from literature are applied and compared, which form the two methods - ISO 14179-2 and the joint model to estimate the power losses in a transmission. A 2-speed transmission in an electric vehicle is used as a case study to compare the two methods and validate them with experimental data.
