Spiral Bevel Gears

Spiral Bevel Gears

Spiral Bevel Gears & Pinions ground manufactured 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

Spiral – Hypoid Gears and Pinions

Ondrives are able to manufacture spiral bevels and hypoids in different styles and types. Spiral bevel teeth designed and made to give an optomised output.

Hypoid Gears

Hypoid gears offset Ground and Pinions

Ground Hypoid pinions and gears manufactured 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
