Helical Gears | McMaster-Carr

The helical teeth on these gears stay in contact for longer than straight teeth, which allows them to transmit higher loads at higher speeds than spur gears.. For gears to mesh correctly, they must have the same pressure angle and pitch. All of these gears transmit motion in a straight line— make sure to get one left-hand and one right-hand gear. To change speed and torque in your assembly ...
