一机部机械研究院汽车后桥主、被动螺旋伞齿轮是汽车配件生产中的短线产品,由于它一方面需要使用18CrMnTi优质合金钢材,另一方面加工复杂,特别在制齿方面,需要五台昂贵的进口专用格里森机床及一整套加工刀具、磨刀、调整等辅助设备,所以一般的中小工厂,特别是一般汽车修配厂,很难自己进行生产,不少单位因为这种齿轮供应不上而影响了汽车的正常运输。为了贯彻毛主席的“自力更生”、“土洋并举”、“大、中、小并举”的方针,我们对用球墨铸
After the first mechanical rear axle, the passive helical bevel gear is a short-term product in the production of automobile parts. Because of the need to use 18CrMnTi high-quality alloy steel on the one hand and complicated processing on the other hand, especially for making teeth, Expensive imported special Gleason machine tools and a set of processing tools, sharpening, adjustment and other auxiliary equipment, so the general small and medium factories, especially the general auto repair shop, it is difficult to produce their own, many units because of this gear supply is not Affected the normal transport of cars. In order to carry out Chairman Mao’s principle of “self-reliance,” “simultaneous development of both land and ocean,” and "big,
