弹性定位圆柱销

定位销 不锈钢弹性圆柱销-常规负载型
弹性圆柱销又称弹簧销，是一种无头中空的圆柱体，轴向开槽处有规则排列的锯齿形结构，两头端部有倒角。这类销的外径比装配孔径稍大一点。

带齿弹簧销，有时也被称为开槽销、卷制弹性销，是一种端部倒角的空心圆管式压装紧固件。弹性卷销用作锁定装置、定位、轴或套筒连接。
使用受限于您的想象力和技术能力。开槽销也称为滚销或弹簧销。卷制滚销有时称为螺旋销。信诺华工业的弹簧销种类繁多，有多种材料、表面处理和尺寸规格。
一般来说，弹簧销的自由直径设计为大于销所在孔的尺寸

带齿弹簧销的安装--弹簧力在安装时向孔内壁径向施加压力，提供其出色的减震功能。

同时其良好的机械强度和重量轻是开口带齿弹簧销的一些优点。

但是，如果未按照正确使用，弹簧销会有断裂的风险。

另外需要注意的是。固定销的两端是一条关键规则。如果在仅固定在一端的使用情况下，安全系数必须仔细慎重考虑，以避免双重剪切荷载。

1、使用说明

1） 在要安装销的部件上钻孔时，不要在需要剪切载荷的位置对孔进行倒角

带齿弹簧销应用注意事项：

2） 避免在振动方向与销轴平行的位置使用销。

3） 对于销的剪切面，必须保持距销端的最小长度，等于销的直径。

4） 一般来说，安装孔是通过在安装销的零件上打孔来制备的。钻孔时每个零件的直径尺寸变化应限制在销槽未完全闭合的程度。

5） 在预期会产生重大冲击载荷的地方使用前，确保先进行测试。

弹性定位销可以组合使用以增加其剪切强度。两个销的剪切强度的增强幅度大约可以增加30-40%。

在组合两个销时，最好不要在同一方向对齐开槽处。如页面下方图片所示。

Spring Pins - Teeth type

Spring Pins, sometimes referred to as slotted pins, rolled pins or coiled rolled pins, are hollow, cylindrical tube-style press fit fasteners with chamfered ends. Rolled pins are used as locking devices, positioning points, anti-chafing surfaces, shafts, or sleeves for wiring. Usage is limited only by your imagination and technological capabilities. Slotted pins are also known as roll pins or spring pins. Coiled roll pins are sometimes called spiral pins. Sinohua industries's large assortment of spring pins are available in a variety of materials, finishes, and sizes.

Spring pins can be doubled up for added shear strength.

Spring pins are pins made by rolling a strip of metal into a cylinder with a slot running along its length, which is 
then heat-treated. The free diameter of the pins is designed to be larger than the size of the holes where the pins are 
installed; in that way, spring force applies pressure radially to the interior wall of the hole when installed, providing 
its excellent retaining function against vibrations.
Their fine mechanical strength and light weight are some of the advantages of spring pins.
However, spring pins run the risk of fracture or breaking if the instructions for use shown below are not 
followed. Fixing both ends of a pin is a key rule. In usage cases where they are fixed on only one end, safety factors 
must be carefully considered to avoid double shear loads.
1. Instructions for Use
1) When making holes in components in which pins are to be installed, do not chamfer holes where shear load is to be 
applied.
2) Avoid using a pin to where the direction of vibration is parallel to the pin’s axis.
3) For the shear plane of the pins, a minimum length must be maintained from the pin’s end, equal to the diameter of the pin.
4) Mounting holes are, as a general rule, prepared by making holes in the parts in which pins are mounted. When drilling 
each part individually, diameter size variations shall be restricted to the amount by which the pin slots do not fully close.
5) Make sure to perform tests before use in places where significant impact load is expected.
6) The breaking strength of pins is slightly greater (approx. 6%) when the pin’s slot is placed in line with the force than 
when pin’s slot is placed square to it. As a result, be sure to take the direction the pin’s slot faces into account when 
shearing strength is a consideration.

Using in Combination pins
You can combine pins so as to increase their shear strength. The shear strength of both pins is combined. It is 
best not to align the slots in the same direction in combining two pins.

Important notes:
Toothed type slotted pins are not suitable for use as stoppers, because the stress concentration caused by 
the load along the teeth tends to cause fractures even with extremely small amounts of force. Use straight 
type slotted pins to prevent this from happening.
