Engine assembly lines using cyclic chain drive , operating workers can only work on one side . The engine assembly process , some components to be mounted in the opposite side of the station for the pipeline , for ease of operation , the level required to operate the engine after 180 ° rotation . The rotating device design requirements for graduation four years of undergraduate science expertise to design an engine when assembled , can be easily assembled. First, according to the desired objectives to be achieved, the program selects the most reasonable rotation ; followed by the rotation of the proposed scheme requires , for the overall design of the mechanism , the mechanism to determine the overall layout ; Then , the structure of the main parts of the design and look-up table complete the selection of standard parts ; last assembly drawing of the entire organization and important parts diagram , and the corresponding parts for the strength, stiffness lifetime checked. The cam design will change the past but can not easily achieve the intended function of the wear characteristics of a long life, high accuracy , is a more reasonable way to improve .
