在机械零件中的轴与轴套有转动要求时,需注加润滑油。润滑油一般是由套上的油孔流入转动表面的,也有从轴孔流入转动表面的。如内燃机的曲轴就是这样。轴上的油孔一般在设计时都考虑防止油孔口刮伤轴套。要求在油孔倒角处还要倒一个过渡圆角(图1)。它表面粗糙度一般不超过
In the mechanical parts of the shaft and sleeve rotation requirements, the need to add lubrication. Lubricating oil generally flows into the rotating surface through the oil hole, and also flows into the rotating surface through the shaft hole. Such as the internal combustion engine crankshaft is like this. Oil hole on the shaft is generally considered in the design to prevent the oil hole scratches the sleeve. Requirements at the chamfer of the hole but also down a transition fillet (Figure 1). It does not exceed the surface roughness generally
