A helical gear, also known as a spur gear with a helix, is a type of toothed gear that has its teeth cut in a helix or spiral shape along the gear's axis. This design allows for increased contact between gears and enables them to transmit torque more efficiently while reducing noise and vibration. Helical gears are commonly used in applications where smooth operation is essential, such as in transmissions and machinery.
