与卡扣环比较，用于光负载的灯载环可以是成本有效的解决方案。

如果你必须坚持配合组件的组件，你可能已经使用过保留戒指.
保持环是流行的紧固选择，因为它们紧凑，并与其他紧固件相比消除了复杂的加工过程。
选择右挡环对于您的应用程序来最大限度地减少您的成本，应用程序大小和汇编时间非常重要。
这篇博客将讨论过度设计和分享有用的提示，以简化您的设计，以节省时间和金钱。
What is load capacity, and why is it important?
Let’s start by defining装载能力, also referred to as thrust capacity. Load capacity is the maximum force that can be applied to a retaining ring without failure. Knowing your ring’s load capacity is important and even critical in some cases because it can affect your application’s function, reliability, and safety. If your application requires a high load capacity, but you select a ring with a low load capacity, the ring may come out of the groove.
此外，如果您的设计需要轻量负载，但选择具有高负载能力的环，戒指可能太大，适用于应用程序，难以安装，最有可能，您支付的比您所需要的更多。
您的应用程序确定负载容量
Your load capacity will vary depending on your application. If you plan on using a retaining ring in a semi-truck transmission or a downhole drilling tool, your load capacity requirements will be much higher than in an air nozzle or a pressure gauge. See the application details below.
轻型，单回到保持环是用于仅需要轻负载的飞机上的空气喷嘴的经济高效的解决方案。轻型环紧密地安装在塑料空气通气壳体的凹槽中。其角度环端部设计成靠近，提供近乎完整的360度的支持。
A light-duty, single-turn retaining ring installed in a shallow groove exerts light pressure on the glass lens in this pressure gauge. This economical design provides the optimum load at all points along the circumference without breaking the glass.
保持戒指更大更大吗？
我们都听到这个词，更大更好，但它如何适用于保留戒指？通常，较大（较重）保持环的横截面是其负载能力越高。这是我们有时会在其中看到客户通过选择比其应用程序更高的负载能力更高的挡环来设计应用程序。
使用挡环额定电荷容量的缺点是什么？
如果您的申请不需要它，它只是设计矫枉过正。
If your application doesn’t have high impact or thrust loads, heavier duty rings are more expensive, heavier, and harder to install and remove, therefore wasting your time and money. Why pay for the high thrust capacity of a heavy-duty retaining ring when it is not a requirement, and the application can operate as designed with lighter loads?
What retaining ring should I use for light-duty applications?
我们创造了一个Light-Duty Retaining Ring Series(VH.&vs.,Imperial/vhm.&vs.M,Metric)专为轻型应用而设计。在这些低间隙应用中，轴向定位而不是负载承载是主要功能。
The Light-Duty Retaining Rings are:
- Ideal for light loads和低间隙应用
- 经济 - 降至成本的一半卡扣
- 易于安装和删除compared to a heavier duty ring
- Customizable– design what you need with No-Tooling-Charges™
在碳和不锈钢中，轻型保留环的原有量是¼“至10”（6毫米至300毫米）。
概述
- Knowing the load capacity of your ring and the application will help you select the right retaining ring.
- If your application doesn’t have high impact or thrust loads, heavier duty rings are more expensive, heavier, and harder to install and remove, therefore wasting your time and money.
- Smalley的轻型挡圈系列（VH.&vs.,Imperial/vhm.&vs.M,Metric)is the ideal solution for light-duty applications because they are economical, light-weight, easy to assemble, and customizable.
