变速箱的尺寸、重量和成本多数取决于其传递动力的零件特别是齿轮的尺寸。除了经典的初步设计和终计算方法外，现代的类比方法、有限元（ＦＥＭ）方法，数据基数和程序链对优化目的是有用的，这些计算方法已用许多实例说明。在被通常应用证实之前，该计算方法已在基础研究中被验证 The size, weight and cost of a gearbox depend largely on the dimensions of the parts it powers, especially the gears. In addition to the classic preliminary design and final calculation methods, modern analog methods, finite element (FEM) methods, data radixes and program chains are useful for optimization purposes and have been described by many examples. This calculation has been validated in basic research until it is commonly used
