前言长期以来,在内燃机产品设计中,对曲轴主轴承及连杆轴承的计算仍然采用较粗略的计算方法。如对其最大比压、平均比压及作为发热指标的P V值等进行校核。这样的方法虽然简单但很粗略,很多对轴承工作有重要影响的因素没能考虑进去。
Foreword For a long time, in the design of internal combustion engine products, the calculation of crankshaft main bearing and connecting rod bearing still adopted a more rough calculation method. Such as its maximum pressure, the average pressure and P V as an indicator of heat to check. Although this method is simple but very rough, a lot of factors that have a bearing on the bearing work can not be taken into account.
