shear pin

In the constant load and live load under the action of shear pin, and the circumferential weld will withstand high amplitude of cyclic stress, the strength and fatigue problem should cause height to take seriously.

在恒载和活载的作用下，剪力销以及其周边焊缝将承受幅值较高的应力循环，其强度和疲劳问题应引起高度重视。

To overcome the shortcomings of the shear pin type joint and left-hand thread type joint, a sliding sleeve subsurface safety joint is developed.

为了克服剪钉式和反扣式两种安全接头的不足，研制出一种滑套式井下安全接头。

The shear strength of the perforated brick masonry is much higher than which of ordinary brick masonry is indicated in the shear experiment. The mainly reason of mortar's pin key action and the second reason of cementing bond difference between brick and mortar are found.

受剪试验表明多孔砖砌体抗剪强度高于普通砖砌体抗剪强度，主要原因是砂浆的销键作用，其次是砂浆与块体的粘结力的差异。

So from this time forth the shear pin must be designed on the basis basis of fatigue strength and it may be changed at operation condition of unit.

剪断销应按疲劳强度设计并考虑在不停机条件下可以更换。
