Helical gears are cylindrical gears with teeth cut at an angle relative to the gear axis. This angled tooth design allows gradual engagement between gear teeth, resulting in smoother transmission, lower noise, and higher load capacity compared with spur gears.
Helical gears are widely used in gearboxes, automotive transmissions, industrial machinery, and automation systems where stable and efficient power transmission is required.
