    听到很多客户前来咨询弹簧垫圈时,说到他们之前有做过的弹簧垫圈都有开裂的情况,我们分析了一下,主要导致裂开的原因有以下几点:

    When many customers came to inquire about the spring washer, they said that the spring washer they had made before had cracks. We analyzed the main reasons for the cracks as follows:

    1.材料本身不可。

    1. The material itself is not good.

    2.热处理硬度过高,淬透性不好。

    2. The hardness of heat treatment is too high and the hardenability is not good.

    3.电镀氢脆。

    3. Hydrogen embrittlement in electroplating.

    弹簧垫圈在一般机械产品的承力和非承力结构中应用广泛,其特点是成本低廉、安装便当,适用于装拆频繁的部位。

    Spring washer is widely used in the load-bearing and non load-bearing structures of general mechanical products. It is characterized by low cost, easy installation and suitable for frequent assembly and disassembly.

    但是弹簧垫圈的防松能力很低!尤其在目前欧美各国要求高可靠性产品中采用率极低,特别是重要的承力结构连接部位早已被抛弃好多年。我们国家在军工方面还有部分应用,但以改进为不锈钢材料。

    But the anti loosing ability of spring washer is very low! Especially in the European and American countries, the adoption rate of high reliability products is very low, especially the important bearing structure connection parts have been abandoned for many years. In our country, there are still some applications in military industry, but the stainless steel materials are improved.

    据说,钢制弹簧垫圈在CASC早就是被禁止使用了!也说是很不安全,原因有两个1是“涨圈”2是氢脆。

    It is said that steel spring washer has been banned in CASC for a long time! In other words, it is very unsafe. There are two reasons. One is "rising circle" and the other is hydrogen embrittlement.

    所以用户要根据本身的使用特性来使用不同的材料以及后期处理工序。这点可以咨询弹簧垫圈的生产厂家,相信他们的技术能够帮您解决这个难题。

    Therefore, users should use different materials and post-processing procedures according to their own characteristics. This point can consult the manufacturer of spring washer, I believe their technology can help you solve this problem.
