helical gear

Helical gear is a type of cylindrical gear widely used in the field of mechanical transmission. From an external perspective, it shares a commonality with all cylindrical gears, namely, an overall cylindrical shape. However, unlike spur gears where the teeth are parallel to the axis, helical gears have teeth with an inclination angle. This means there is an angle formed between the helical gear’s tooth’s extension line and the axis. By adjusting this inclination angle to make it parallel to the axis, it transforms into a spur gear.

The teeth of a helical gear are designed at an angle. Compared to gear types with direct engagement, its transmission effect is smoother, effectively reducing impact and noise generated during engagement. This contributes to improving equipment stability and reducing operational noise. The helical design also minimizes friction losses, leading to enhanced transmission efficiency and greater torque transmission capacity compared to direct engagement. Therefore, helical gears are more suitable for applications requiring substantial torque transmission, such as mechanical transmission systems and industrial machinery.
