What Gears For Parallel Shafts?

There are several types of gears that can be used for parallel shafts, including:

1.Spur gears: Spur gears are the simplest and most common type of gear used for parallel shafts. They have straight teeth that run perpendicular to the gear axis, and they are designed to transmit power between parallel shafts.

2.Helical gears: Helical gears have angled teeth that are cut at an angle to the axis of rotation. This design reduces noise and vibration, and can transmit more torque than spur gears.

3.Double helical gears (also called herringbone gears): Double helical gears have two sets of helical teeth that are cut in opposite directions. This design cancels out the axial forces that are generated by helical gears, resulting in smoother operation.

4.Bevel gears: Bevel gears are used to transmit power between non-parallel shafts that intersect at an angle. They have conical-shaped teeth that are cut at an angle to the gear axis.

5.Worm gears: Worm gears are used to transmit power between non-parallel shafts that are perpendicular to each other. They have a threaded shaft (the worm) that meshes with a toothed wheel (the worm gear).

The choice of gear type depends on the specific requirements of the application, such as torque, speed, and noise level.
