箱体孔的同轴度、主轴前后支承轴颈的同轴度、轴承内外圈的径向跳动和端面跳动以及主轴轴肩跳动等元件误差，都会影响主轴组件的精度。

Based upon SIMPLEC algorithm of CFD analysis, air film flow in the oil-free air bearing is simulated to illustrate its working principle, as well as performance's influence from air compressibility, shaft eccentricity ratio, clearance size and rotating speed.

基于计算流体动力学中的SIMPLEC算法，从流动模拟分析的角度对动压气膜轴承的工作机理，包括气体可压缩性，轴承间隙大小，轴颈偏心率及轴承运行线速度的作用等作了分析。

Engine work, if crude oil filter was a serious blockage of impurities, or due to low temperatures when the oil viscosity changes, the main oil缺油Road will be the engine will lose lubrication, this is very dangerous, especially in the main bearings and connecting rod bearings, if there is no oil will be burned, bearing alloy heat due to friction loss and even journal welded together, eventually forcing the engine to stop working.

发动机工作时，若机油粗滤器被杂质严重淤塞，或者由于气温低而机油粘度变大时，主油道就会缺油，发动机就会失去润滑，这是很危险的，特别是主轴承和连杆轴承，如果没有润滑油会烧坏，轴承合金会因摩擦发热而流失，甚至和轴颈熔焊在一起，最终迫使发动机停止工作。
