Where two axles cross at point and engage by means of a pair of
conical gears, the gears themselves are referred to as bevel gears.
These gears enable a change in the axes of rotation of the
respective shafts, commonly 90°. A set of four bevel gears in a
square make a differential gear, which can transmit power to two
axles spinning at different speeds, such as those on a cornering
There are four basic types of bevel
- Straight bevel gears:
These gears have a conical pitch surface and straight teeth
tapering towards an apex
- Zero bevel gears:
This is similar to a bevel gear except the teeth are curved. In
essence, Zero Bevel Gears are Spiral Bevel Gears with a spiral
angle of zero
- Spiral bevel gears:
The teeth are curved teeth at an angle allowing too contact to be
gradual and smooth
- Hypoid bevel gears:
These gears are similar to spiral bevel except that the pitch
surfaces are hyperboloids rather than cones. Pinion can be offset
above or below gear center, thus allowing larger pinion diameter,
and longer longer life and smoother mesh, with additional ratios e.g.,
6:1, 8:1, 10:1
The design of bevel gears results in thrust forces away from the
apex. With the bearing limitations the gears have to be carefully
designed to ensure that they are not thrown out of alignment as they are
