ABSTRACT
The development of machine manufacturing industry, the dependence is at the machine manufacturing of forerunner technique, and the share of market. How therefore the improvement process a craft, exaltation process accuracy, decrease process man-hour, create sex exploitation work to equip have, economy cost, exaltation product of forerunner and usage, exaltation product of market competition ability, will be us design core problem within process. This time design main aim at tradition of the double be allied slippery move wheel gear to process craft route to carry on research and design. The wheel gear which include a tradition among them process the knife, work equip to have and inside the bore process tongs of improvement design, and improve manufacturing quality and efficient of tow axis, three gears of EQ140 truck’s gear-box.
