Problems solved by technology
[0003] In the field of connection locking and load bearing, for the joint connection of two parts, the ordinary triangular thread cannot play the role of connecting the two parts; for load bearing, the ordinary triangular thread can only play a bearing capacity in the direction of the thread axis, because the thread radial direction has no The force, the internal thread and the external thread tooth form are not constrained by each other in the radial direction, and the tooth form is easy to disengage

Embodiment Construction
[0015] In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the following will briefly introduce the accompanying drawings that need to be used in the embodiments. Obviously, the accompanying drawings in the following description are some embodiments of the present invention. Ordinary technicians can also obtain other drawings based on these drawings on the premise of not paying creative work.
[0016] see figure 1 , the embodiment of the present invention provides a self-locking thread (10, 20), the angle bisector of the tooth angle (a, b) of the self-locking thread (10, 20) is not perpendicular to the axis L of the thread .
[0017] Further, the included angle a between the angle bisector of the tooth profile angle (a) of the self-locking thread (10) and the axis line L of the thread is 1 is an acute angle.
[0018] Further, the angle b between the angle bisector of the tooth profile angle (b) of the self-locking thread ...

Provided is a self-locking thread. The angular bisector of a thread angle of the self-locking thread is not perpendicular to the axis of the thread. In the self-locking thread, an overlapped action face M is formed between the side face of the thread angle of an inner thread body and the side face of the thread angle of an outer thread body, so that the acting force of the side face of the thread angle of the inner thread body on the face M is decomposed into axial force parallel with the axis of the thread and radial force perpendicular to the axis of the thread, in the same way, the acting force of the side face of the thread angle of the outer thread body on the face M is decomposed into axial force parallel with the axis of the thread and radial force perpendicular to the axis of the thread, and the purposes of joint connection of two parts and avoiding of disengagement through self-locking are achieved through the simultaneous action of the axial force and radial force of the thread.
Description
technical field [0001] The invention relates to the technical field of thread connection, in particular to a self-locking thread and a seam-riding connection method. Background technique [0002] Threads are divided into four types: triangular thread, trapezoidal thread, rectangular thread, and zigzag thread according to tooth type. Triangular thread is mainly used for connection locking and load bearing, and trapezoidal thread, rectangular thread and zigzag thread are mainly used for transmission. The common feature of the four threads is that there is force only in the direction of the thread axis, and there is no force in the radial direction of the thread. [0003] In the field of connection locking and load bearing, for the joint connection of two parts, the ordinary triangular thread cannot play the role of connecting the two parts; for load bearing, the ordinary triangular thread can only play a bearing capacity in the direction of the thread axis, because the thread ...
