    These offer a refinement over spur gears. The leading edges of the teeth are not parallel to the axis of rotation, but are set at an angle. Since the gear is curved, this angling causes the tooth shape to be a segment of a helix. The angled teeth engage more gradually than do spur gear teeth, causing them to run more s...

    These overcome the problem of axial thrust presented by "single" helical gears by having two sets of teeth that are set in a V shape. A herringbone gear (double helical gears) can be thought of as two standard mirror image helical gears bonded together side-by-side to form a single gear. This cancels out the ...

    Bevel gears are useful when the direction of a shaft's rotation needs to be changed. They are usually mounted on shafts that are 90 degrees apart, but can be designed to work at other angles as well. The teeth on bevel gears can be straight, spiral or hypoid. Straight bevel gear teeth actually have the same problem...

    Spur Gear is the simplest, most common type of gear used. They consist of a cylinder or disk with the teeth projecting around the entire circumference, and although these teeth are not straight-sided in form, the edge of each tooth is straight and aligned parallel to the axis of rotation.These gears can be meshed toget...
