涡轮增压器的液体摩擦轴承,在大多数情况下,是决定增压器工作能力的一个部件。增压柴油机所用的涡轮增压器使用过程表明,支承表面磨损和烧伤程度是不断加重的。磨损厉害以及转子在轴承座中运转不稳定都能引起涡轮动叶片和固定件相碰。理论上的计算表明,考虑到工作过程中的这些因素,转动零件和固定零件之间的初始间隙可以减少到0.4～0.5毫米或减得更小些。为了证明理论上的结论,并确定在轴承座中的轴颈中心运动的轨迹的影响,对叶片和盖罩之间的最小间隙,即工作过程中的最小间隙
The turbocharger liquid friction bearings, in most cases, are a component that determines the turbocharger’s ability to work. Turbocharger turbochargers used in turbocharged diesel engines indicate that wear and burns on the bearing surfaces are aggravating. Bad wear and rotors in the bearing instability can cause the turbine blades and fasteners collide. Theoretical calculations show that taking into account these factors in the work process, the initial clearance between the rotating part and the fixed part can be reduced to 0.4 to 0.5 mm or less. In order to prove the theoretical conclusion and to determine the influence of the trajectory of journal center movement in the housing, the minimum clearance between the vane and the cover, ie the minimum clearance during operation
