spiral bevel gear

Spiral bevel gear is one of various types of bevel gear. As the name suggests, “spiral” refers to the way its teeth extend in a spiral manner, not extending from the axis directly. A complete tooth has a curved spiral shape. It is also referred to as a “spiral bevel gear set” because it is composed of a wheel gear and a pinion gear, with their teeth spiraling in opposite directions. This design enables the gears to gradually engage in a helical manner, effectively reducing noise and impact, improving smoothness, and extending the lifespan of the transmission. Theoretically, a spiral bevel gear set consists of two separate gears. However, in practical design and production, the wheel gear and pinion gear should be considered as a whole, requiring coordinated production rather than separate manufacturing.
