齿轮惯量的计算,通常是近似计算轮齿重和齿的回转半径。这种惯用计算法,对于大多数齿轮惯量的计算来说,是令人满意的。当要求计算值有高精确度时,这种计算法有着不能接受的误差。回转半径是从齿轮中心到被认为是整个断面质量重心间的距离。对于在平板形圆盘或厚轮圈上切齿的。齿轮,其值易于得到。然而,单独计算齿的回转半径通常是近似的。同样,轮齿的重量 The calculation of gear inertia is usually approximated by calculating the gear tooth weight and the radius of gyration of the tooth. This idiomatic calculation is satisfactory for most calculations of gear inertia. This calculation has an unacceptable error when it comes to requiring high accuracy of the calculated values. The radius of gyration is the distance from the center of the gear to the mass center of mass that is considered as the entire cross-section. For flat-shaped discs or thick wheels on the gear. Gear, its value is easy to get. However, calculating the radius of gyration of the teeth separately is usually approximate. Again, the gear’s weight
