HELICAL GEAR

grabcad

A helical gear, also known as a spur gear with a helix, is a type of toothed gear that features an inclined, thread-like pattern along its length. This design allows for the transmission of rotational motion between two shafts at an angle, which can be useful in various applications such as speed reduction or increasing torque. The helical gear's unique shape also reduces noise and vibration compared to a straight spur gear.
