Design of sprocket tooth profile for composite pitch block chain transmission by LU Jianfu, SHOU Qifeng, ZHANG Kefei, ZHOU Zhidi, SHOU Yulai, SUN Bing

“…For this purpose, a design method of two circular arcs and one straight line tooth profile of the block chain sprocket was proposed for the sprocket tooth profile design of composite pitch block chain drive.MethodsAccording to the meshing principle of chain drive, under the meshing state when the number of sprocket teeth was determined, the calculation formula of the pitch-circle diameter for the theoretical calculation was obtained by introducing the equivalent pitch based on the feature that the included angle between the inner and outer chain links was kept constant.ResultsThe application results of the design example show that it is feasible to adopt the design of two circular arcs and one straight tooth profile for the sprocket of composite pitch block chain, and can provide design reference for engineering technicians. …”
