Spiral Bevel Gears

Spiral Bevel Gears

Spiral Bevel Gears & Pinions ground on the Gleason 280G in closed loop (Gleason GEMS® Design -Ground-Measured and closed loop to maintain the design).

Spiral Bevel Gears and Pinions Ratios 1:1 – 8:1
1Mn – 10Mn 22mm tooth depths Typ. 25° – 45° Sprial Angles
Ø15mm – Ø280mm
Completing with duplex tooth taper
Gear generated or FORMATE (plunge) ground

Gleason GEMS® used by Ondrives for Spiral Gear Design. 
▪ 3D gear and pinion graphics with animation.
▪ Combined ease-off and TCA for pinion and gear.
▪ Interactive tooth surface and ease-off correction and optimization.
▪ Real blank geometry for both pinion and gear.
▪ 2D tooth profiles along the face width.
▪ 2D/3D loaded TCA, including interactive root bending stress and contact stress output with S-N Curves

Hypoid Gears

Hypoid gears offset Ground and Pinions

Ground Hypoid pinions and gears with offset Ratios 3:1 – 10:1
1Mn – 10Mn 22mm tooth depths.
Upto Ø280mm
Offsets  10%-20% of pitch diameter typical is 10-15%
Enlarged pinion compared to spiral bevel pinion

Gleason GEMS®  Hypoid TCA

High Ratio Hypoid

HRH and SRH gears & pinions extreme high offsets with high ratios.

Ground HRH pinions and gears ratios 5:1 – 100:1
1Mn – 2.25Mn
Parallel tooth depth
High pinion offsets 20-33% of outside diameter of gear
