碟形弹簧的外形象一个无底的碟子,图1a为其常见的形状。这种弹簧能以很小的变形量获得较大的负荷,其轴向尺寸很小,重量轻,价格便宜,所以广泛应用于缓冲、避震等场合;并在冲压模具、阀类、离合器、紧固件以及石油和地质等工程机械上获得普遍的应用。由于碟形弹簧的负荷——变形特性是非线性的,因此它还可以应用在许多特殊的场合。例如,一些离 The shape of a disc spring is like a bottomless dish, with its usual shape shown in Figure 1a. This spring can be a small deformation to obtain a larger load, the axial size is small, light weight, cheap, it is widely used in cushioning, shock absorption and other occasions; and stamping dies, valves, clutches, Fasteners and construction machinery such as oil and geological access to a wide range of applications. Because of the non-linear load-deformation behavior of disc springs, it can also be used in many special applications. For example, some distance
