[0016] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0017] Example

[0018] like Figure 1 and Figure 2 As shown, an axially locked taper self-locking mechanism, the taper locking member 1 has a threaded hole and an axle pin hole, the outer taper anti-rotation disc 3 can be fixed to the taper locking member 1 through a hexagon socket countersunk screw 6 to form an outer taper assembly; the inner taper disc 2 and the inner taper anti-rotation disc 4 are connected through a fastening screw 5 to form an inner taper assembly. Both the inner and outer taper assemblies have limiting bosses and can be staggered.

[0019] When assembling Figure 3 As shown, first align the center of the outer cone assembly with the inner cone assembly, adjust the outer cone anti-rotation disk 3 and the inner cone anti-rotation disk 4 until they are engaged with each other, and then fully insert them into the center of the circle to limit the displacement and rotation in all directions, and finally complete the assembly.

[0020] The locking mechanism mainly adjusts the nominal taper by adjusting the two nominal cone diameters and the tolerance cone length. The inner cone disk 2 mainly includes an inner cone surface that matches the cone surface locking member 1. The cone angle tolerance must meet the standard, and at least the contact area after matching must be above 80%, so that there is sufficient static friction to ensure self-locking. At the same time, the limiting bosses of the outer cone stop disk 3 and the inner cone stop disk 4 are cross-engaged to further improve the stability of the fixation and the quickness of the concentric locking.

[0021] This embodiment aims to achieve an efficient and stable self-locking effect through an innovative structural design. The self-locking mechanism is mainly composed of an inner cone disk 2, a cone surface locking member 1, and a limit stop disk. The tapered locking member is designed with a tapered surface, which forms a tapered fit with the corresponding tapered hole on the mating member. Through the action of the limit device, a tight fit between the tapered locking member and the mating member is achieved. The mechanism uses the principle of tapered fit and combines the mechanical structure design so that the contact area gradually increases after assembly, and the locking force is more evenly distributed, thereby achieving an efficient and reliable self-locking effect.

[0022] The above-mentioned embodiments only express the specific implementation of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
