Helical Gears

Helical gears are like spur gears in that they are usually manufactured from cylindrical gear blanks and are most frequently used to transmit power and motion between parallel shafts. The primary difference between the teeth of spur gears and those of helical gears is that whereas spur gear teeth are oriented parallel to the axis of rotation, helical gear teeth are cut at an angle. Because of this tooth form, helical gears can also be used to transmit motion between shafts that are situated at various angles in different planes. Some of the advantages of using helical gears as opposed to spur gears in parallel shaft arrangements are that pairs of helical gears will run both smoother and quieter than spur gear pairs. Additionally, because meshed helical gears will have more teeth in contact with mating gears at any time helical gears can transmit higher loads than spur gears of the same size. Also, like spur gears the helical gear has an involute tooth form in the transverse section (parallel to the axis of rotation) so small changes in mounting distance will not adversely affect the action of the gears.
