| Popis: | A method of manufacturing involute sprocket by a standard cutter for the toothed chain is suggested. The application of involute sprockets compared with straight and standard tooth profiles has a number of advantages: noise abatement under operation, wear resistance and durability increase, etc. The selection order of a standard cutter (hob gear) for cutting involute sprockets is presented. A computer program simulating the sprocket cutting process with different values of the chain pitch and various numbers of teeth is developed. The resource allows determining the tool module, and inspecting tooth for sharpening and facing. The characteristic feature of cutting sprockets with the involute tooth profile is the application of two corrections (radial and tangential). Their computation procedure is presented. The calculations for the chain pitch tц = 12.7 mm are carried out. The results are summarized in the table. The range of cutting involute sprockets with a standard cutter by the chain pitch tц, the module (m), and the number of sprocket teeth (z) is determined including the need to eliminate tooth sharpening and facing. |
