Spiral Bevel Gears
Spiral Bevel Gears are to straight bevel gears what a helical
gear is to a spur gear.
Spiral Bevel Gears supersede straight bevel gears where
greater strength, higher speed and/or less noise is needed in an
angle gear set.
In order to get better performance out of a parallel shaft
application a helix angle is introduced in the
straight tooth. This helical tooth shape gets more teeth
engaged,
which results in a gear set that can operate under greater loads
at higher speeds without excessive noise.
In the same way a spiral angle can be introduced in a bevel
tooth form, which allows more tooth engagement and load sharing.
Spiral Bevel Gears are recommended when speeds exceed 1000
RFM or 1000 SFPM.
With the right tooth form and equipment Spiral Bevel Gear
teeth can also be ground for greater accuracy resulting in even
less noise and vibration.
Nissei is capable of supplying low cost ground-tooth Zerol®,
spiral and hypoid pinions and gears. This is made possible by
Nissei's super abrasive grinding technology using "CBN" plated
grinding wheels.
Nissei's Spiral Bevel Gears are available up to:
M-8.0, 3.0 D.P., 12" P.C.D. |
