Smalley Wins GM Supplier Quality Excellence Award for 6th Consecutive Year

内部弹性挡圈用作孔/外壳内的可拆卸轴肩。这些内部挡圈具有多种配置。对于需要内部弹性挡圈的应用，Smalley 提供 Spirolox^® 或内部螺旋弹性挡圈、Hoopster^® 挡圈、等截面挡圈和 WaveRing^®。这篇博客文章探讨了这些内部弹性挡圈之间的差异，并强调了每个挡圈的潜在应用。

Welcome to another edition of Ask the Expert, a series in which expert Smalley Engineers answer difficult questions about retaining rings and wave springs.

What is the minimum work height of part CM20-L1 if made with carbon steel SAE 1070-1090? What is the load at that height?

This specific part was designed to be compressed to a work height of 2.72 mm to achieve a load of 35 ± 3.5 N. 

Smalley stocks over 11,000 standard rings and springs for applications in nearly every industry worldwide. We also understand, however, that the uniqueness of some applications may demand something that isn’t readily available from stock. When that occurs, our team of expert engineers is ready and willing to help you design a part that fits your needs.

Bolts are a common fastener used to connect two or more components in an assembly. Although bolts can be used as an inexpensive method of assembly, Smalley Spirolox® Retaining Rings can be used as an alternative in some instances to reduce assembly time, weight, and machining costs. As an added benefit, Spirolox retaining rings provide a more aesthetically pleasing assembly.

1. Reduced Work Height

In applications with tight space constraints, Crest-to-Crest^® Wave Springs can take up to 50% space than a traditional coil spring. This space saving is made possible with the sinusoidal waves formed in the flat wire. This results in a more compact spring that takes less material to produce and can reduce the overall weight of the spring and assembly.

Internal retaining rings act as a removable shoulder within a bore/housing. These internal rings come in a variety of configurations. For applications that require an internal retaining ring, Smalley offers Spirolox^® or internal spiral retaining rings, Hoopster^® rings, constant section rings, and WaveRing^®. This blog post explores the differences between these internal retaining rings and highlights potential applications for each.
 

Spirolox®弹性挡圈按照其字面是指专门用于固定孔或轴的部件。它与市场上其他挡圈的区别在于设计上采用了无凸耳 “No Ears to Interfere®”，因此无阻碍组装。如果无“凸耳”或“凸缘”，Smalley的挡圈是怎样安装的？

我们的挡圈可以很容易地手工安装。将弹性挡圈单独卷绕并将其末端插卷入凹槽。内部和外部安装过程相同。

安装半自动化和自动化Spirolox® 弹性挡圈的流程如下：
