1) Features of Helical Gears
Helical gears can transmit energy between parallel or perpendicular axes through the use of helical teeth.
They are designed to distribute pressure gradually along the whole tooth.
Because of their tooth inclination, helical gears run smoother and quieter than other gears and are able to carry heavy loads efficiently.
2) Types of Helical Gears
Helical gears are available in two teeth configurations: left handed and right hand.
Helical gears transmit energy through two axial configurations: parallel and perpendicular.
