求翻译：轮轴承中的浮动轴承，而且现代汽车的涡轮增压器轴承大多使用浮动轴承，所以耐用实惠。而浮动轴承实际上是套在轴上的圆环，圆环与轴以及圆环与轴承座之间都有间隙，形成双层油膜。圆环浮在轴与轴承座之间。一般内层间隙为0.05mm左右，外层间隙大约为0.1mm。轴承壁厚约3.0-4.5mm，用锡铅青铜合金制造，轴承表面镀一层厚度约为0.005-0.008mm的铅锡合金或金属铟。增压器工作时，轴承在轴与轴承座之间转动。因此，我们可以发现浮动轴承的缺点：涡轮轴高转运转阻力大，机油压力和品质要求高，对涡轮轴的动态控制不稳定。是什么意思？

Wheel bearings, bearing, and the float of the modern automotive turbocharger bearings are mostly using the floating bearings, the durable price. In fact, floating bearing is set on the shaft in the circle, the circles and the shaft, as well as between the circle and the bearing clearance, and there

Floating bearings wheel bearing, but modern cars mostly use the floating bearing turbocharger bearings, durable and affordable. Float is actually set on the axis of the bearing rings, and rings and bearing ring and shaft there are gaps between, forming double-layer film. Circle floating in between s
