现有有关减速箱(减速器)的文献一般很少论及轴承的支轴结构问题,至于壳体零件(机壳)的变形和强度计算则更是少见。但是,整个减速箱的工作能力,无论是对于保证啮合齿轮相对位置的精度,还是机壳本身的可靠性,都在很大程度上取决于机壳的强度和变形。机壳通常决定了整个减速箱的重量、加工量和成本,因此,可以通过对壳体零件结构的优化来大大改善减速箱的现有制造和使用水平。根据机壳工作条件,减速箱可以分为两 Existing literature on gearboxes (gearboxes) generally seldom addresses the problem of the bearing’s fulcrum structure, and the calculation of the deformation and strength of the shell parts (enclosures) is even more uncommon. However, the ability of the entire gearbox to work, whether for ensuring the accuracy of the relative position of the toothed gear or the reliability of the housing itself, depends to a large extent on the strength and deformation of the housing. The housing generally determines the weight, throughput, and cost of the entire gearbox so that the gearbox’s current manufacturing and usage levels can be greatly improved through the optimization of housing components. According to the chassis working conditions, gear box can be divided into two
