T611镗床主轴箱传动系统设计 摘要：目前，在机械加工工业中，机械产品大批量生产中，组合机床已得到广泛运用。一些复杂的壳体类零件，加工工艺复杂、定位夹紧困难的工件，要提高其加工精度、生产效率，单凭普通机床是很难办到的，而在用普通机床加工复杂工件的过程中，对操作者的技术也提了较高的要求，这就迫切的要求生产一定数量的组合机床。这样，不但可以提高零件的加工精度和生产率，而且成本低、生产周期断，适合我国的经济水平、教育水平和生产水平。更能够在激烈的竞争中为企业获得更多利润、提高企业核心竞争力。T611镗床是一种主要用镗刀在工件上加工孔的机床。通常用于加工尺寸较大、精度要求较高的孔，特别是分布在不同表面上、孔距和位置精度要求较高的孔，如各种箱体、汽镗发动机缸体等零件上的孔。卧式镗床的主轴水平布置并可轴向进给，主轴箱沿前立柱导轨垂向运动，工作台可纵向或横向运动，可钻、扩、铰、和镗孔及镗削内、外螺纹、攻螺纹、镗外圆柱面、端面及用端面铣刀、圆柱铣刀铣平面等。 关键字：主轴变速齿轮齿轮模数滚动轴承 Abstract： At prese
