Abstract: On the basis of analyzing and comparing three kind of schemes including existing runout slot, no runout slot and spliced assembly to design and manufacture the herringbone gear of F-1300 mud pump which have three carboys and single effect, the three kind of schemes were analyzed by evaluating the strength of gear, the woke life and the cost. The conclusion in-
dicates that the scheme is the excellent to manufacture the herringbone gear which has no runout slot by shaving gear,and the indicator of the scheme was the highest when the ratio of work life of gear and the cost price to manufacture gear was regarded as the weighing indicator. Finally , considering three factors of other of influencing scheme evaluation , by the method of
weighted scoring in the value engineering theory,it has been carried on the synthetical analysis , and the mentioned above conclusion has been confirmed by the result further.
