A helical gear's teeth are placed at an angle (relative to the gear's axis) and take the shape of a helix. This permits the teeth to progressively mesh, first with point contact and progressing to line contact as engagement develops. Less noise is one of the most obvious advantages of helical gears over spur gears, especially at medium- to high-speeds. Furthermore, with helical gears, several teeth are always in mesh, resulting in reduced strain on each individual tooth. This causes a smoother transfer of forces from one tooth to the next, reducing vibrations, shock loads, and wear.
However, the inclined angle of the teeth generates sliding contact between the teeth, resulting in axial forces and heat, reducing efficiency. These axial forces are important in bearing choosing for helical gears. Helical gears require thrust or roller bearings, which are generally bigger (and more expensive) than the basic bearings used with spur gears since they must endure both radial and axial forces. The size of the tangent of the helix angle affects the axial forces. Despite the fact that bigger helix angles enable faster and smoother motion, the helix angle is generally limited to 45 degrees owing to the generation of axial forces.
