机械设备安装过程中，经常遇到轴与轴套间过盈配合，该过盈配合压人力可按文献［’冲公式计算，但在实际应用时过于复杂，本文据此公式作进一步推导，得出如下估算公式。轴与轴套过盈配合压人力计算公式为：P＝ZPi。rZV（l）式中P一过盈配合压人力22一轴与轴套接触面半径l一轴与 Mechanical equipment installation process, often encounter the interference fit between the shaft and the shaft sleeve, the interference with pressure human pressure according to the literature [’red formula, but in practical application is too complicated, this formula is derived from this formula, draw Calculate the formula as follows. Interference with the shaft and sleeve pressure with human pressure formula is: P = ZPi. rZV (l) where P-interference with a human pressure 22 shaft and sleeve contact radius l axis and
