Spiral Bevel and Hypoid Gear Manufacturing UK

Spiral bevel and hypoid gears are matched gear-set systems whose tooth geometry depends on the complete shaft arrangement. Ondrives supports their design, manufacture, grinding and inspection using specialist Gleason systems.

Spiral bevel and hypoid geometry

Spiral bevel gears normally work between intersecting axes, while hypoid geometry introduces an axis offset. That offset changes tooth geometry, sliding conditions and packaging, so the pinion and gear should be treated as a matched pair.

Closed-loop design, manufacture and inspection

Ondrives' published capability includes closed-loop work for spiral bevel, hypoid and high-ratio hypoid gears. This links design intent, machine settings and measured tooth geometry so corrections can be controlled rather than treated as separate stages.

Mounting data matters

Ratio, shaft angle, offset where applicable, mounting distance, backlash, bearing arrangement and contact pattern all influence the final gear set. Include them when a new set is engineered.

Starting a bevel or hypoid enquiry

Send any existing gear-set data together with ratio, shaft arrangement, offset, torque, speed, space envelope and mounting constraints. For replacement work, include both members of the pair where possible.

Need help with a specific gear? Send Ondrives the drawing, model or available gear data. For new designs, include the operating duty and mating-component information so the manufacturing route can be reviewed in context.

Matched geometry and mounting control

Spiral bevel and hypoid gears are sensitive to the geometry and mounting of the complete pair. Hypoid sets additionally use shaft offset, so the pinion and gear cannot be treated as independent catalogue-like involute members.

Axis arrangement and spiral direction

Confirm shaft angle, ratio, rotation direction, pinion/gear hand and hypoid offset. Spiral bevel and hypoid teeth use spiral-angle and hand conventions rather than cylindrical-gear helix angle β. Retain the complete matched-set definition; ISO 23509-1:2025 is the current published ISO macrogeometry reference.

Mounting data

Mounting distances, bearing positions, housing stiffness and backlash influence the operating contact pattern. Production drawings should preserve the design reference data needed to reproduce the set.

Closed-loop verification

Design, manufacture and analytical inspection are linked. Measurement results can be used to verify or refine the manufacturing setup and the intended flank geometry.

For reverse engineering or replacement work, provide both members where possible together with assembly/mounting information. Do not assume a new member will correctly mate with an unidentified or worn existing partner.
