Helical gears have involute teeth cut at an angle to the face of the gear. When the teeth of the gears engage, the contact starts from an end and gradually spreads with the rotation of the gears, until the two teeth come to be in complete contact. Helical gears have a big advantage over spur gears in operation as generally they run more smoothly and more quietly with less vibration. The longer and strong teeth give greater contact surface area, this makes helical gears ideal for carrying heavy loads at higher speeds.Finishes available to our clients are as cut or for greater precision shaved or for high precision gears we can offer gear tooth profile grinding.
