兰州油泵油嘴厂技术科推荐了一个螺旋弹簧的设计方法。当弹簧的工作负荷P_z为已知(一般是规定的),压缩行程λ也为已知,只要选定最大负荷P_λ=2.5 P_z,这个弹簧就可以设计出来。步骤如下:1.定弹簧刚度η及foη=(P_λ-P_z)/λ=(1.5/λ)P_zfo=P_z/n=λ/1.52.根据工作性质及要求选定许用应力 Lanzhou pump factory technology recommended a coil spring design method. When the spring load P_z is known (usually specified) and the compression stroke λ is also known, the spring can be designed as long as the selected maximum load P_λ = 2.5 P_z. The steps are as follows: 1. Set the spring stiffness η and foη = (P_λ-P_z) / λ = (1.5 / λ) P_zfo = P_z / n = λ / 1.52. Select the allowable stress according to the nature and requirements of work
