Sprocket is a kind of wheel with cogged chain teeth, which is used to mesh with blocks with accurate pitch on chain link or cable. Sprocket is widely used in chemical industry, textile machinery, escalator, wood processing, three-dimensional garage, agricultural machinery, food processing, instrumentation, petroleum and other industries of mechanical transmission.
 
Tooth profile of sprocket
The tooth profile of sprocket must ensure that the chain can enter and exit the meshing smoothly, reduce the impact and contact stress of the chain link as much as possible, and be easy to process. See Figure 1 for commonly used sprocket end profile. It is composed of three arcs AA, AB, CD and a straight line BC. The tooth profile is processed with standard cutter. It is not necessary to draw the end face tooth profile on the working drawing of sprocket. It is only necessary to mark "the tooth profile is manufactured according to 3rgb1244-85" on the drawing. However, the axial face tooth profile of sprocket should be drawn. Refer to relevant design manual for its size.
 
Sprocket structure
Four kinds of sprocket structures are commonly used. Small diameter sprockets are generally made into integral type, while medium diameter sprockets are mostly made into spokes. In order to facilitate handling, clamping and weight reduction, holes are opened on the spokes. Large diameter sprockets can be made into combined type. At this time, the ring gear and wheel core can be made of different materials. For example, C45, stainless steel and other materials.
 
Sprocket material
Sprocket material should ensure that the teeth have enough strength and wear resistance, so the sprocket tooth surface is generally heat treated to achieve a certain hardness.
