Abstract

一种带螺纹的连接件(10)具有改善的在螺纹(16)被砂质材料污染时咬合并紧固螺纹(16)的能力。将轴向的槽(18)添设至螺纹(16)的阳半部分(14)和/或阴半部分(12)，能够通过为污染物提供“逃跑路径”而使紧固动作将砂质污染物从螺纹的啮合部排出。

Description

抗污染式螺纹
技术领域
本申请要求2009年3月26日提交的美国申请序列号61/163,582的权益，该申请的内容在此通过引用并入。
背景技术
本发明的公开内容
本发明改善了在螺纹被砂质材料污染时的咬合并紧固螺纹的能力。
将轴向的槽添设到螺纹的阳和/或阴半部分，能够通过为污染物提供“逃跑路径”而使紧固动作将砂质污染物从螺纹的啮合部排出。在传统的螺纹中，当砂砾小于螺纹间隙时，和/或砂砾比螺纹间隙大很多时，紧固动作有时随着紧固的发生而将污染物连续地排出。但是当砂砾尺寸与螺纹间隙相当时，砂砾可能会卡在啮合部中，从而阻止进一步紧固。然而，采用本发明，反复地部分地松动然后紧固该部分会使污染物运动至轴向的槽中和/或使污染物压碎，从而允许螺纹被完全地紧固。槽如果被设置在阳部分或***分中则是有效果的，且如果槽存在于阳部分和***分两者中则会看到某些另外的改善。槽应径向地至少与阳部分的小直径或***分的大直径一样深，且当槽径向地比其深时会看到另外的改善。并且添设被连接至那些槽的径向逃跑口能够提供甚至更短的路径和更有效的对砂砾的排斥。
在该部分最初被靠拢在一起时，这些槽可能增大了螺纹不对准的可能性(“螺纹错扣”)，但是添设“导向直径”(在咬合部的开始处被去除的螺纹)基本上消除了螺纹错扣。
如果没有槽，螺纹和砂质污染物的某些结合使得在对该部分没有过多努力和/或不损坏的情况下实现紧固变得不可能。槽的添设允许了这些结合的大部分被牢固地紧固，特别是如果使用增量的松动然后紧固的步骤时。
本发明的这些或其它的目的和优点将从下面的结合附图的描述中更全面地显示，其中贯穿几个视图，相似的参考符号指的是相同或类似的部分。
附图简述
图1是采用本发明的带螺纹的连接件的***分的视图。
图2是采用本发明的带螺纹的连接件的横截面。
图3是带螺纹的连接件的***分的横截面图。
实施本发明的最佳模式
通常标记为10的本发明是包括***分12和阳部分14的带螺纹的连接件。螺纹16可具有任意已知的尺寸或几何形状。多个槽18中的一个可设置成沿着带螺纹的连接件的纵向轴(或旋转轴)而轴向地延伸。在优选的实施方式中，槽18设置在连接件的***分12中，但是槽18也可定位在阳部分14(如图2所示)中或者定位在***分和阳部分两者中。
此外，在优选的实施方式中，槽18比在***分12上的螺纹16的底部或根部16a延伸得更深(对于***分12来说径向地更远)。这为污染物提供了待被推入的路径。
涵盖了可对带螺纹的连接件做出各种变化和修改而不偏离本发明的如权利要求所限定的精神和范围。

Claims (6)

1.一种带螺纹的连接件，该带螺纹的连接件具有阳部分和***分以及纵向轴，每一部分具有在其上的互补的螺纹，改进在于，包括延伸穿过所述部分中的至少一个上的所述螺纹的至少一个轴向地延伸的槽。
2.如权利要求1所述的带螺纹的连接件，其中，所述槽具有深度，并且所述螺纹具有深度和根部，其中所述槽的深度比所述螺纹的深度大。
3.如权利要求1所述的带螺纹的连接件，其中，所述槽被定位在所述***分上。
4.如权利要求1所述的带螺纹的连接件，其中，至少一个所述槽被定位在所述阳部分上。
5.如权利要求1所述的带螺纹的连接件，其中，至少一个所述槽被定位在所述***分上。
6.如权利要求1所述的带螺纹的连接件，其中，至少一个所述槽被定位在所述部分中的每个上。
