Machine and equipment manufacturers
today are feeling more pressure
than ever to reduce costs without sacrificing
machine performance — a balancing
act difficult to achieve. OEMs often overlook a simple solution that can have a positive, long-term impact
on profitability for themselves and

End market conditions for the power transmission industry continue to worsen. With the Euro down 13% year to date and U.S. oil production surging we are seeing increasing headwinds, if not storm clouds, for the sector.
In recent years the estimation of gearbox power loss is attracting more interest — especially in the wind turbine and automotive gearbox industry — 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.
Spiroid and worm gears have superior advantages for hightorque and miniaturization applications. And for this reason they are particularly preferred in aerospace, robotic and medical applications. They are typically manufactured by hobbing technology, a process with a typical overall lead time of 4 to 14 weeks.
