An efficient and environmentally friendly way of manufacturing gears

21.01.2004


EUREKA project E! 2339 EUROENVIRON GRINDING project has developed an alternative, flexible and environmentally friendly manufacturing technology for the production of gears that can reduce production times from months to a matter of days.


It can be used for all kinds of gears and joints made from treated alloyed steel, heat-resistant nickel or titanium alloys, such as those used in turbine and jet engine blades.

The current production process for industrial gears is expensive in terms of labour, materials and time. It involves the manufacture and maintenance of gear-cutting tools, the cutting and shaping of a blank and heat and thermo-chemical treatments. In comparison, the new process “is based on precision deep grinding by a shaped grinding wheel that improves both quality and productivity of the final gears. These unique tools are made by fusing abrasive grains of alumina corundum and silicon carbide to the surface of the tool with strong ceramic bonds,” says Josef Frumar, Production Manager at Czech lead partner Carborundum Electrite a.s.

The project partners hope that this new technique of grinding exact gear shapes may become an alternative to conventional practice which relies on distinct metalworking methods to obtain precision cutting edges. In Russia alone, the annual demand for grinding wheels is over 50,000 units. “The introduction and adoption of the new gear-manufacturing technology will make it possible to increase the production rates and quality of finished gear products,” concludes Frumar.



Carborundum Electrite a.s. may have 100 years of experience in the production of grinding wheels, but an unsuccessful privatisation trial during the last decade left it without an R&D department. “Our Russian partner carried out the fundamental research while we provided trial testing and implementation,” explains Frumar.

Prof. Viktor Starkov, Director of the Research Centre at the Moscow State Technical University, ’Stankin’, describes how it carried out most of the research work. “We developed various formulae for new high-porosity tools and conducted industrial tests in 14 Russian factories, together with theoretical analysis and experimental research, which created a basis for the development of this new technology of gear production by profile depth grinding.”

Frumar describes the benefits of being in a EUREKA project: “The EUREKA scheme provided the perfect chance for international co-operation on projects which will produce products that are the first on the market and ahead of our competitors.”

Im Focus: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: RAVAN CubeSat measures Earth's outgoing energy

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
