Abstract

一种自锁螺纹，属于可在任何场合使用的防松螺 纹系统，其特征是α外小于α内，优点是可消除六个 自由度，实现自锁，且结构简单、适用范围广、工艺要 求低；上述自锁螺纹的制造工具简单，成本低，功效 高。

Description

本发明涉及一种自锁螺纹，属于可在任何场合应用的防松螺纹联接系统，以及制造这种自锁螺纹的工具。
为了保证装配，螺纹孔和螺栓的公差需要在螺栓外径与螺孔根径之间存在间隙，这样导致了螺栓与螺孔之间存在相对横移的可能性，并且不可避免地会造成螺栓中心线与螺孔中心线不同轴的后果，在重载荷的振动下，特别是横向振动下，内外螺纹之间由于存在前述的间隙，将会产生相对的横向位移，导致螺纹间的摩擦力消失，此时螺纹就会被振松。试验表明，即使是拧得很紧的螺栓也会在横向振动下松开。
本发明的目的是提供一种既具有理想防松效果，而结构又非常简单的螺纹联接系统，以及其制造工具。
本发明是这样实现的：把外螺纹牙尖角“α外”做成小于内螺纹牙尖角“α内”，即“α外”∠“α内”，旋紧时，螺纹系统将确保消除六个自由度，实现自锁。制造上述本发明的工具是这样实现的：把制造外螺纹的内丝板牙尖角“α内板”做成小于制造内螺纹的外丝锥牙尖角“α外锥”，即“α内板”∠“α外锥”，就可以制造出“α外”∠“α内”的自锁螺纹系统。使用时，内外螺纹可以从两个方向拧入。
本发明与现有技术相比，有如下优点：1、可消除六个自由度，螺纹不会松动，实现自锁;2、结构简单，易于制造;不需特殊的牙型有的自锁功能;4、制造工具简单;5、制造过程的工艺要求降低，使成本下降，功效提高。
下面对本发明作进一步的描述。
在具有内外螺纹的螺纹系统中，把外螺纹牙尖角“α外”做成小于内螺纹牙尖角“α内”，即“α外”∠“α内”;制造本发明的工具，其内丝板的牙尖角“α内板”小于外丝锥的牙尖角“α外锥”。上述的角度“α外”、“α内”、“α内板”和“α外锥”可以是正值，也可以是负值。
