轴与孔的配合当要求有较高的精度时,往往需要高精度的精加工。然而使用波纹圈就能在保证配合精度的前提下大大降低机加工的要求,把尺寸公差放宽近十倍。从而避免了高精度加工的困难,显著降低机加工成本。波纹圈是一种薄钢板卷成具有均匀间隔纵向波纹的弹性圈,它是一种特殊的摩擦紧固件。在轴与孔的配合中,将波纹圈挤在两个配合表面之间,由于挤压使这些纵向波纹产生变形,紧贴在与它接触的表面,通过摩擦作用达到紧固的目的。波纹圈的英文名称
Coordination of the shaft and the hole When the higher precision is required, precision finishing is often required. However, the use of corrugated ring can ensure the accuracy of the premise of greatly reduce the machining requirements, the size tolerance to relax nearly ten times. Thus avoiding the difficulty of high-precision machining, significantly reducing machining costs. Corrugated ring is a thin steel coil into a uniform interval longitudinal ripple elastic ring, it is a special friction fastener. In the cooperation of the shaft and the hole, the corrugated ring is squeezed between the two mating surfaces. Due to the extrusion, the longitudinal corrugations are deformed and tightly adhered to the surface in contact with the corrugated ring so as to achieve the purpose of fastening by friction. English name of the corrugated ring
