Gears

Spiral-shaped gears, also known as helical gears, are used in various mechanical applications to transmit power and motion between two parallel shafts. These gears have teeth that are cut at an angle to the gear's centerline, allowing for a smoother operation and reduced noise compared to spur gears. Helical gears can be used individually or in pairs, with the direction of tooth engagement determining whether they function as right-hand or left-hand gears.
