1) Description of Helical Gear
Helical gears are one type of cylindrical gears with slanted tooth trace.
Compared to spur gears, they have the larger contact ratio and excel in quietness and less vibration and able to transmit large force.
A pair of helical gears has the same helix angle but the helix hand is opposite.
2) Feature of Helical Gear
Helical gears produce axial thrust force. Therefore, it is desirable to use thrust bearings to absorb this force.
