When left-handed and right-handed helical gears with the same twist angle are combined, it is called a double helical gear. Double helical gears transmit rotational motion between two parallel shafts and…

Helical gear is a cylindrical gear with a slanted tooth trace. A higher contract level, less vibration, quietness, and an ability to transfer larger loads make a helical gear more efficient than a spur gear….
