Helical Gear A helical gear, also known as a screw gear, is a type of toothed wheel that features an involute profile and a helix angle. This design allows for both parallel and angular motion between two gears, making it suitable for various applications such as speed reducers, transmission systems, and timing devices. The helical shape of the teeth also enables quieter operation compared to spur gears due to the way forces are distributed.
