Sprocket tooth profile and parameters

Tooth Profile: The tooth profile of a sprocket is typically a three-circular arc and straight line profile, consisting of three circular arcs and one straight line. This tooth profile has relatively low contact stress at the meshing point, high load-carrying capacity, and can be processed using standard tools, facilitating manufacturing and maintenance.
Parameters: The main parameters of a sprocket include the number of teeth, pitch, roller diameter, pitch circle diameter, top circle diameter, and root circle diameter. These parameters determine the Size and performance of the sprocket, and also affect the matching degree and transmission efficiency with the chain.
