Bevel gears are conical gears used to transmit motion between intersecting shafts, typically at 90 degrees. The teeth are cut on a cone rather than a cylinder, allowing power transmission between non-parallel axes.
See how bevel gears compare to other common gear types across key engineering criteria.
| Feature | Bevel Gear | Spur Gear | Helical Gear |
|---|---|---|---|
| Noise Level | — depends on tooth type (straight vs. spiral) | — sudden tooth engagement | — gradual engagement |
| Load Capacity | — conical geometry distributes forces well | — single-tooth contact | — multiple teeth share load |
| Efficiency | — complex contact geometry | — simple parallel axes | — slight axial thrust loss |
| Cost | — specialized conical machining | — simplest to manufacture | — angled cutting setup |
| Complexity | — precise cone angles, critical mounting alignment | — straightforward parallel mounting | — thrust bearings needed |
| Typical Applications | Differentials, hand drills, marine drives, printing presses | Clocks, conveyors, pumps, printers | Automotive transmissions, industrial gearboxes |
