Structure design of roller chain sprocket

 1. The tooth profile of the sprocket 

 The tooth profile of the sprocket must ensure that the chain enters and exits the mesh smoothly and freely, minimizes the impact and contact stress of the chain link during meshing, and is easy to process.  The tooth profile of the commonly used sprocket is shown in Figure 1.It is composed of three arcs aa, ab, cd and a straight line bc, referred to as three arc-straight tooth profile.Standard for tooth profileCutterFor processing, it is not necessary to draw the tooth profile of the end face on the sprocket work drawing, just indicate "the tooth profile is manufactured according to 3RGB1244-85" on the drawing, but the shaft face tooth profile of the sprocket should be drawn, as shown in Figure 2. Refer to the relevant design manual for dimensions.The parameter calculation has been mentioned before, so I won’t repeat it! 

 2. Sprocket structure  Figure 3 shows four commonly used sprocket structures.Small-diameter sprockets are generally made of integral type (Figure 4a), and medium-diameter sprockets are mostly made of spoke plate type. In order to facilitate handling, installation and weight reduction, holes are made on the spoke plate (Figure 3b). Large diameter sprockets can be Make it into a combined type (Figure 3d), at this time the ring gear and the wheel core can be made of different materials!For example, C3, stainless steel and other materials. 

 3. Sprocket material  The sprocket material should ensure that the gear teeth have sufficient strength and wear resistance, so the sprocket tooth surface is generally heat treated to make it reach a certain hardness.
