2.最大许用压力速度系数的验算 对于轴承考虑到轴与轴承的摩擦热,需要对压力速度系数进行验算。最大许用压力速度系数的标准值已列于前面表2中。 考虑pv值时端轴颈尺寸求法如下: 间存在下列关系式: 把公式(24)绘制成计算图表9。下面举例介绍其使用方法。 例11某一端轴颈上承受
2. The maximum allowable pressure coefficient of speed checking For bearings considering the friction heat of the shaft and bearing, the need to check the pressure rate coefficient. The standard values for the maximum allowable pressure rate coefficient are listed in Table 2 above. Consider the pv value when the end journal size is determined as follows: The following relationship exists: Formula (24) is plotted as Calculation Chart 9. Here’s an example of how to use it. Example 11 on one end of the journal
