现今普遍采用的各种轴承计算方法中,绝大多数都未考虑部分周向油槽的存在.为了使动载轴承计算从定性向定量方面前进一步,本文在考虑部分周向油槽具体结构的前提下,用数值计算方法求出了按任何要求精度逼近于动载轴承中压力分布精确值的解,并拟订了相应的通用计算程序.此外,还对不同的油槽尺寸下的情况进行了分析比较.计算表明,不考虑油槽时承载能力可能是考虑油槽时承载能力的几倍甚至更多,油膜反力的方向二者则可能相差几十度甚至更大.这充分说明了在动载轴承计算中考虑部分周向油槽的重大影响.
Nowadays, most of the bearing calculation methods commonly used today do not consider the existence of some circumferential oil grooves.In order to make the calculation of dynamic load bearing a step further from qualitative to quantitative, under the premise of considering the specific structure of some circumferential oil grooves, , The solution to the accuracy of pressure distribution in any bearing is obtained by numerical calculation and the corresponding general calculation program is drawn up.In addition, the analysis and comparison of the different tank sizes are also carried out. The calculation shows that the bearing capacity without oil tank may be several times or more considering the bearing capacity of the oil tank and the difference between the directions of the oil film reaction force may be several tens of degrees or even more.This fully shows that in the dynamic bearing calculation Consider the significant influence of some circumferential oil sumps.
