Helical gears are a type of cylindrical gear with teeth cut at an angle to the gear axis, forming a helix shape. This design allows for smoother and quieter operation compared to spur gears. Helical gears can transmit motion and power between parallel or crossed shafts with higher load capacity and better efficiency. They are widely used in applications that require high speed, high torque, and low noise.
