英文摘要：

In order to improve the stability of sintering machine, a new compound tooth profile of sprocket wheel is studied, the original tooth profile is optimized, and a unified equation of the tooth profile is derived according to the movement characteristics and the working conditions of pallet cars. The optimized tooth profile is discussed by means of analyzing the velocity, acceleration and displacement characteristics of compound tooth profile curve based on the actual size of the sprocket wheel. The study results indicate that the optimized tooth profile of the compound tooth is reasonable, the meshing conditions between sprocket wheel and pallet car is improved. The brushftre contact impact can be avoided using new tooth shape, and make system run smoothly. The results provide a theoretical basis for aoolications of new sinterin~, machines with even-number tooth.
