### Helical Gears

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

Learn to calculate gear forces in parallel axis spur and helical gears. Spur gears only generate forces in the gear plane, however helical gears generate an axial force component therefore need to be supported axially as well. Tangential and radial forces in the gear plane cause bending moments on the supporting shafts. Axial force generates bending in the perpendicular plane.
