Structural characteristics of sprockets
Tooth profile design: The tooth profile of the sprocket should be easy to process, not easily detached, and ensure that the chain enters and exits the mesh smoothly and smoothly, while also ensuring even force distribution on the chain.

Typical application scenarios of helical gears
Transmission: Manual/automatic transmissions widely use helical gears to achieve smooth shifting and reduce jerking. For example, in the Toyota Aisin 6-speed automatic transmission, the proportion of helical gears exceeds 80%.

The transmission advantages of helical gears
When the helical gear meshes, the contact line gradually increases from zero to the maximum value, and then shortens to disengagement. The load loading/unloading process is smooth, effectively reducing impact and vibration. Its coincidence degree (number of teeth meshing simultaneously) is 30% -50% higher than that of spur gears, further enhancing smoothness.

Core structural characteristics of helical gears
The tooth profile of a helical gear is spiral wound around a cylinder, and its teeth form a fixed angle (helix angle, usually 8 ° -25 °) with the axis. According to the different spiral directions, it can be divided into two types: left-handed and right-handed.
