齿轮重量越小,几何尺寸越小,则转动惯量越小,圆周速度越小。从而动载荷减小,使传动更为平稳。动载荷减小了,反过来又可把齿轮尺寸设计得小些。齿轮重量和几何尺寸减小,则整个齿轮传动的重量和几何尺寸将随之减小。从而节约材料,减小占地面积和保养费用等。因此,使齿轮重量为最小是设计传递动力的齿轮传动应该考虑的一个要素。 The smaller the weight of the gear, the smaller the geometric size, the smaller the moment of inertia and the smaller the peripheral speed. Thus reducing the dynamic load, so that the transmission is more stable. Dynamic load is reduced, in turn, the gear size can be designed to be smaller. As the gear’s weight and geometry decrease, the weight and geometry of the entire gear drive will decrease. Thus saving material, reducing floor space and maintenance costs. Therefore, minimizing gear weight is one element that should be considered in designing a gear transmission that transmits power.
