Gear noise is a common evil any gear manufacturer must live with. It is often low enough not to be a major problem but, at times, gear whining may appear and then, tracking the source and, especially, curing the ill can be tricky at best.
There's never been a better time to put the spotlight on e-drive transmissions and electric vehicles. They're obviously not just coming: they're already here. Just check out any auto show or
showroom. That's why Gear Technology magazine is pleased to present the first installment in a series of chapters excerpted from Dr. Hermann J. Stadtfeld's newest book, "E-Drive Transmission
Guide - New solutions for electric- and hybrid transmission
vehicles."
Mathematically precise tooth surface definition and contact
analysis help to develop state-of-the-art straight bevel gears for
many industrial applications. The new Coniflex-Plus manufacturing
process utilizes high-speed dry cutting with production
times per slot which are about twice compared to the fast
Revacycle process.
We know that for cylindrical gears we have the standard DIN 3964 for defining deviations of shaft center distance and shaft position tolerances of casings. And for bevel gears? Is there some specific standard for defining deviations of center distance and shaft position tolerances of casings (orthogonal shafts), as DIN 3964 do?
