碟簧是一种特殊的弹簧,形状像圆形垫片,不同材料的金属机械配件

　　碟簧是一种特殊的弹簧，形状像圆形垫片，不同材料的金属机械配件。因为它看起来像盘子，所以它被称为盘子弹簧。　　一般来说，它通过相当数量的叠加来提供足够的弹性拉伸，并发挥作用。　　由于刚度变化和安装紧凑，广泛应用于机械设备工业、石油工业、汽车工业和航空航天工业。圆柱形螺旋弹簧被广泛取代。　　结构类型：　　圆盘弹簧通常由金属带、板或锻坯冲压而成，其负荷与变形非线性。圆盘弹簧按工艺方法分为1、2、3类，按各类型、工艺方法和圆盘弹簧厚度划分。　　一般分为普通蝶形弹簧、带径向槽的蝶形弹簧和梯形截面蝶形弹簧。由于单个蝶形弹簧的变形量和负荷值往往不能满足要求，因此一般采用组合。碟簧的组合方式可分为多种，即对合、叠合和复合(由对合组合)。碟簧的吸振性能不低于圆柱形螺旋弹簧。当使用叠合组合时，由于碟簧片之间的摩擦，它具有很大的阻尼和消散冲击能量。在很大程度上，圆盘弹簧正在取代圆柱形螺旋弹簧。常用于重型机

高温预紧碟簧的分类与选择

　　在精度不低于1%的试验机上测量和加载组合碟簧的负荷。(i≤10片，对合组合)试验时使用润滑剂，两端压板硬度需要在52hrc以上。　　碟簧的变形在试验机上压缩成品碟簧圆盘弹簧3次，第二次和第三次压缩后测量自由高度。　　碟簧硬度按gb/t230.1或gb/t440.1的规定执行。厚度为1mm，厚度为>1mm，洛氏硬度计上的试验压痕应在碟簧表面中心。每件4点，一点不评估，取后3点的平均值　　单碟簧在疲劳试验机上用等正弦波负荷进行试验。试验可以单片进行，也可以由小于或等于10片的样品组成。组合试验需要在使用符合要求的工装试验前加预压，单片变形量f=(0.15~0.2)ho，应力振幅根据使用寿命要求按图确定。　　(1)碟簧的特点如下:　　1.刚度大，缓冲吸振能力强，能以小变形承受大载荷，适用于轴向空间要求小的场合。　　2.具有刚度变化特性，该弹簧具有广泛的非线性特性。　　3.使用相同的圆盘
