Welcome back to the Ask the Expert Blog, where our engineers answer commonly asked ring and spring design questions.  This week, our experts field some questions about Spirolox retaining rings, specifically about their reusability, and the usefulness of Smalley Sales Engineers.

斯迈利之所以成为波形弹簧和挡圈技术的全球领导者，与我们销售工程师尽心尽力的声望是密不可分的。

销售工程师不同于销售人员，销售工程师首先必须是一名工程师。斯迈利的销售工程师运用工程师的专业知识和技能去了解您的具体需求和想法，并给出最适合您情况的解决方案。销售工程师不会无视您的具体需求并推荐给您较昂贵的选择。我们现将这些专业知识通过专家咨询系列直接提供给您。

这一期，是专家领域关于挡圈以及多层密封挡圈的一些问题。其中包括挡圈安装，以及与斯迈利销售工程师讨论具体项目细节。

Welcome back to the Ask the Expert Blog, where our engineers answer commonly asked ring and spring design questions. This week, our experts field some questions about different uses of Smalley springs and rings. We discusses various applications for our line of retaining rings, how they can be adapted to different uses, and when it might be better to select a different product. The expert also talks about some of Smalley’s customization capabilities.

欢迎回到专家博客，该博客旨在帮助您深入了解挡圈以及波形弹簧。本周，专家咨询探讨的是关于波形弹簧设计细节的一些问题。

对顶波形弹簧的设计有哪些局限性？

斯迈利的弹簧产品直径从5毫米，0.197英寸，到3米，9.8英尺，尺寸不同。设计的局限性取决于设计要求的变化，如弹力，变形量，高度，循环等。请联系斯迈利销售工程师来探讨潜在的设计局限性。

什么是波形弹簧的孔腔或轴直径的公差？
弹簧通常有两种方式来测量其直径：一种是测轴直径，另一种是测孔腔直径。鉴于弹簧通常是安装在轴外部，测量弹簧的内侧边缘直径，就是测轴直径。鉴于弹簧也常安装在轴内部，测量弹簧外部边缘直径，就是孔腔直径。

孔直径或轴直径的公差，或任何一种测量，都是指可接受的细微尺寸波动。公差也可以是指在弹簧制造过程中，及弹簧使用过程中，材料膨胀所产生的偏差。公差还可以帮助弹簧更好的适应轴或者孔腔。

欢迎回到专家咨询博客，该博客旨在帮助您深入了解挡圈和波形弹簧。本周，专家咨询探讨缺口型弹簧的性能以及对顶波形弹簧设计规范的问题。

压缩缺口型波形弹簧到其最大压缩高度，会使它弹力改变并变形吗？

任何一个斯迈利设计的波形弹簧，都可以无损伤的压缩到其特定的工作高度。除非是弹簧压缩低于其工作高度，那么，它的结构就会变形。

弹簧的变形会出现弹力和高度上的变化。如果您有这方面的问题，请联系斯迈利的销售工程师。我们工程师设计的弹簧会满足您的应用需要。

Welcome back to the Ask the Expert Blog, where our engineers answer commonly asked ring and spring design questions.  This week, our experts field some questions about retaining rings. Specifically, the production materials that are available and the details of shear load safety factors. For more than 100 years, Smalley has been the industry leader and technological pioneer of retaining rings and constant section rings.

Smalley owes our stature as a global leader in wave spring and retaining ring technology to our dedicated staff of Sales Engineers.

Unlike salespeople, Sales Engineers are engineers first. Smalley Sales Engineers use their technical expertise to steer you in the direction of the products that will best suit your needs instead of the ones that are simply more expensive.
