Abstract

本发明涉及一种有效力矩型复合螺纹。有效力矩型复合螺纹的小径近似椭圆形。本发明结构新颖、简洁，用途广泛，防松效果十分良好。

Description

有效力矩型复合螺纹
本发明涉及一种复合螺纹。
复合螺纹是一种非连续且变截面的螺纹，这种螺纹由左旋和右旋两种不同旋向的螺旋线复合而成，两种螺旋线均匀分布，所形成的螺纹牙底相互交叉。复合螺纹既可以和普通左旋螺纹配合，又可以和普通右旋螺纹配合，复合螺纹的用处广泛，尤其可用在紧固件的防松场合。
本发明的目的在于提供一种螺纹副之间横向可形成摩擦力的有效力矩型复合螺纹。
本发明是这样设计的，有效力矩型复合螺纹的小径近似椭圆形。
由于有效力矩型复合螺纹的小径近似椭圆，而普通螺纹为圆柱形螺纹，在有效力矩型复合螺纹与普通螺纹配合时，普通螺纹和有效力矩型复合螺纹会发生弹性变形，从而使普通螺纹和有效力矩型复合螺纹之间箍紧，横向压紧螺纹，螺纹副之间的摩擦力大大增加，防松效果大大加强。
下面结合附图对本发明作进一步说明。
图1为有效力矩型复合螺纹俯视图(径向图)。
图2为有效力矩型复合螺纹主视图。
图3为有效力矩型复合螺纹侧视图。
在图1中，有效力矩型复合螺纹的小径短轴L1和小径长轴L2不相等，有效力矩型复合螺纹的小径为近似椭圆形，1为有效力矩型复合螺纹的外圆轮廓线。
从图2和图3上也可以看出，有效力矩型复合螺纹的小径短轴L1和小径长轴L2的长度是不相等的。
有效力矩型复合螺纹可以广泛应用于螺纹紧固件的联接。本发明结构新颖、简洁，用途广泛，防松效果十分良好。
