Almost no-one understands complex construction as well as Nidec Graessner, due to the fact that the gear tooth and gear specialist‘s creations are based on more than 65 years of experience.
Intelligent solutions for a wide range of sectors and applications make Nidec Graessner a reliable industry partner in both gear tooth technology and gear construction.
Advantages of Spiral, Hypoid and Zerol® Bevel Gears
High level of coverage due to the fact that several teeth are meshed simultaneously
Resistant to elastic deformation of gears, shafts and bearings
Circular arc gear teeth are more resistant to bending than straight and oblique gear teeth
Very gentle transmission even at high-speed operation and under heavy load
Noise and oscillation damped even at high peripheral speeds
Gear sets can be assembled in your preferred direction of rotation
> 97% efficiency depending upon layout and lubrication
Due to convex tooth-loading the load is not concentrated on the tooth-ends
All gear sets can be ground and/or lapped in pairs upon request
Spiral bevel gears
With circular arc teeth.
Hypoid bevel gears
Similar to spiral bevel gears, but with the drive pinion axially offset either above or below. This means a greater pinion diameter, longer life and more gentle tooth meshing.
Zerol® bevel gears
Zerols are a combination of spiral- and straight-tooth bevel gears with a central spiral angle of 0°.
Type : bevel, hypoid
Teeth : spiral
Other characteristics : hub
