Helical Gear

Detail

Helical gears have teeth lead angle to the axis of rotation. Each pairs of angled teeth is making continuous contact from single point across to the tooth face whereas in spur gear the teeth make sudden contact to the entire face, causing noise and stress. Thus helical gears run more smoothly and quietly than spur gears which makes ideal to be used in higher speed applications, large power transmission and where noise control is essential. Helical gears are normally meshed in parallel or crossed orientations (Skew gears) depend on connection requirements. Helical gears are widely used in automobiles, industrial machinery, reducers and gearboxes.
