轴承式支承转盘的摩擦阻力矩由于影响因素及其变化很复杂,所以很难精确地计算。在设计的时候往往只好估计转盘的摩擦阻力矩,误差很大,因此必须研究尽可能近似的计算公式。已出现的近似计算公式往往最后归结为以下的形式:式中,A为由转盘结构尺寸决定的系数,ΣP_n为各滚动体与滚道法向接触载荷绝对值之和,μ_d为当量摩擦系数。
Frictional resistance moments of bearing-supported turntables are difficult to calculate precisely because of the complexity of the influencing factors and their variations. In the design of the wheel often have to estimate the frictional resistance moment, the error is very large, so you must study as close as possible formula. The appearing approximate formula usually comes down to the following form: where A is the coefficient determined by the size of the turntable, ΣP_n is the sum of the absolute values of the normal contact load of each rolling element and the raceway, and μ_d is the equivalent friction coefficient.
