Sprocket parameter calculation formula: dividing circle diameter: d = p/sin180 ° / z p = pitch can look-up table z = number of teeth

Addendum circle (outside diameter) : D = p * (0.54 + cot180° / z) commonly used sprocket pitch: 3/8 = 1/2 = 5/8 = 12.7 9.525 15.875 15.875 3/4 = 4 5 6 dividing circle diameter: D = p/sin (180° / z) tip diameter: = D + p - 1.25 on3dmax d1dmin = D + p - 1-1.6 / (z) d1 root circle diameter straight: df = D - D note: p section z chain sprocket chain roller diameter d1 the simplest algorithm is {?Points} = dividing circle diameter except with + 2} {teeth sprocket models: contains non-standard sprocket (custom) according to customer's drawings, standard sprocket (American standard and metric).Sprocket commonly used materials: C45 common black process chain sprocket tooth number selection of general principles: 19 tooth or more commonly used in high speed, under normal working conditions of drive sprocket operation.The tooth is used only for 17 section from the drive sprocket.23 or more than 23 tooth recommended for a shock.When the ratio is low, high gear sprocket can be greatly reduced the momentum, I link chain tension load and bearing load.
