Abstract: The uniform motion should be required in production while there is an accelerative motion, for instance, the loop wheel machine in a sintering plant moves at an accelerating speed, which produces a great endogenetic force, and as a result it shortens the life of the equipment. Now, a sprocket with a new kind of tooth shapes is developed so as to achieve both linear speeding up and uniform motion in roller and sprocket drive. Each tooth has its different shape and function, according to which the tooth shapes can be divided into uniform one, accelerating one and compound one. The drawing and the equation for different kinds of shapes of the teeth are presented. This research is simulated on the computer and all the expected results are achieved successfully. It is applied in the model of the sintering machine in Yanshan University, China.

Key words: New kind of tooth shape, Research, Uniform and accelerative motion
