本文叙述弹簧在液压阀中的作用,通过它所起的作用决定了对它的要求,特别是对弹簧的示性线要求,一定要稳定。在过去使用过程中经常发现弹簧钢丝断裂。根据对弹簧的受力分析、计算和试验研究,发现失效的原因主要是弹性指数C太小,曲率太大,其承载能力又较大,其次,制造上也存在一些缺陷。经过反复研究,提出采用碟形弹簧,可克服上述缺点。对碟形弹簧计算方法略作介绍,并通过机器上实地试验,证明效果良好。 This paper describes the role of the spring in the hydraulic valve, through which the role played by it determines its requirements, in particular, the spring line of the show line must be stable. Spring wire breaks have often been found in use in the past. According to the spring force analysis, calculation and experimental study, found that the failure of the main reasons for the elastic index C is too small, the curvature is too large, and its carrying capacity and larger, and secondly, there are also some manufacturing defects. After repeated studies, the use of disc springs, can overcome the above shortcomings. A brief introduction to the calculation method of the disc spring and the field test on the machine prove that the effect is good.
