[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example

[0026] like Figure 1-3 As shown, a super coupling includes a lifting component 1, a guide component 2 and a locking component 3. When the shaft and the sleeve are installed and fixed, the lifting component 1 is set between the shaft and the sleeve, and the lifting component 1 is connected through the guide component 2. The lifting component 1 moves along the guide component 2 to lift and lock the shaft and sleeve to be locked. The lifting component 1 and the guide component 2 are connected through the locking component 3 to move the lifting component 1 between the shaft and the sleeve to be locked, thereby locking the shaft and the sleeve, which has the effects of improving connection reliability, convenient installation and disassembly, and high usability.

[0027] Reference Figure 2 、 Figure 3 The lifting assembly 1 includes a first wedge cone 11 and a second wedge cone 12. The outer walls of the first wedge cone 11 and the second wedge cone 12 are provided with a conical surface 13. The first wedge cone 11 and the second wedge cone 12 are arranged to move toward each other along the small diameter end. The first wedge cone 11 is radially provided with a through hole 111. The locking assembly 3 passes through the through hole 111 to fix the first wedge cone 11 and the second wedge cone 12; the guide assembly 2 includes an outer locking cone sleeve 21 and an inner locking cone sleeve 22. The outer wall of the outer locking cone sleeve 21 abuts against the inner wall of the shaft sleeve to be locked, and the outer wall of the inner locking cone sleeve 22 abuts against A guide channel 23 is provided between the inner locking cone sleeve 22 and the outer locking cone sleeve 21 on the outer wall of the shaft to be locked. By setting the inclination angle of the conical surface 13 and the inner wall of the guide channel 23 to be consistent, the first wedge cone 11 and the second wedge cone 12 are moved along the conical surface 13 and the guide channel 23 and squeeze the inner locking cone sleeve 22 and the outer locking cone sleeve 21 to move outward to both sides to tighten and squeeze the shaft and the shaft sleeve to be locked, and the inclination angle of the conical surface 13 and the guide channel 23 is set between 15 degrees and 75 degrees, and the preferred inclination angle of the conical surface 13 is 30 degrees.

[0028] Reference Figure 2 、 Figure 3The locking assembly 3 includes a locking stud. Threaded holes 121 are machined radially along the second wedge cone 12 at positions corresponding to the through-hole 111. The locking stud passes through the through-hole 111 of the first wedge cone 11 and is threadedly connected to the second wedge cone 12. This moves the first and second wedge cones 11 and 12 radially toward each other, compressing the inner locking cone sleeve 22 and the outer locking cone sleeve 21 to tighten the shaft and sleeve. The locking studs correspond one-to-one with the through-holes 111 and threaded holes 121, and six sets are provided along the sides of the first and second wedge cones 11 and 12. A square mounting hole 231 is processed in the middle position of the guide channel 23, and an extrusion spring 32 is arranged in the mounting hole 231. The extrusion spring 32 is mounted on the locking stud, and one end of the extrusion spring 32 abuts the end face of the first wedge cone 11, and the other end abuts the end face of the second wedge cone 12. The first wedge cone 11 and the second wedge cone 12 are fixed by tightening the locking stud, and the rebound action of the extrusion spring 32 prevents the locking stud from rotating and causing the first wedge cone 11 and the second wedge cone 12 to loosen. Example

[0029] The difference between this embodiment and embodiment 1 is that the locking assembly 3 includes a bidirectional threaded rod, a locking block and a mounting groove. A mounting groove is processed at the connection of the through hole 111 where the first wedge cone 11 and the second wedge cone 12 are located. The mounting groove is an irregular groove. One locking block is threadedly connected to one side of the bidirectional threaded rod and the bidirectional threaded rod is passed through the first wedge cone 11 and the second wedge cone 12 through the through hole 111. The other locking block is threadedly connected to the connection of the bidirectional threaded rod. The locking block is moved to the mounting groove by rotating the bidirectional threaded rod and the bidirectional threaded rod is continued to be rotated to drive the first wedge cone 11 and the second wedge cone 12 to move toward each other and squeeze the inner locking cone sleeve 22 and the outer locking cone sleeve 21 to lock the shaft and sleeve to be locked.

[0030] The working principle of the utility model is as follows: the first wedge cone 11 and the second wedge cone 12 are installed between the outer locking cone sleeve 21 and the inner locking cone sleeve 22, the first wedge cone 11 is installed at the front end, and the second wedge cone 12 is installed at the rear end to form a cone surface 13 to cooperate with each component; the first wedge cone 11 has a through hole 111, and the second wedge cone 12 has an internal thread, and the locking bolt 31 passes through the first wedge cone 11 to connect the second wedge cone 12; when the locking bolt 31 is tightened, the distance between the first wedge cone 11 and the second wedge cone 12 is shortened, and due to the cooperation of the cone surface 13, the first wedge cone 11 is tightened. The wedge cone 11 and the second wedge cone 12 will compress the inner and outer locking rings, causing them to expand radially and press against the outer surface of the locked shaft and the inner surface of the locked sleeve, thereby locking the shaft and the sleeve. When the shaft and the sleeve need to be repaired, the first wedge cone 11 and the second wedge cone 12 can be disassembled by loosening the locking bolt 31 to squeeze and release the inner locking sleeve and the outer locking sleeve and disconnect the shaft and the sleeve. The coupling has a simple structure, ingenious design, light weight, simple use, strong fatigue resistance, high reliability, and easy disassembly, which can greatly improve the maintainability of the system.
