[0002] Gears refer to mechanical components with gears on the wheel rim that continuously mesh to transmit motion and power. The application of gears in transmission appeared very early. The principle of gear cutting and special machine tools and tools that use this principle to cut gears have appeared one after another. With the development of production, the smoothness of gear operation has received attention. Double-jointed forming is also called combined gear.

[0003] According to a detachable gear mentioned in the utility model patent with Chinese patent application number 202021687876.5, the detachable gear has the advantage of being able to replace the damaged part of the gear when in use, which can solve the problem of uneven force on the current gear causing damage to the tooth surface. However, it is not convenient to install and disassemble the two separate gears when in use, and it is not convenient to disassemble a single gear after it is damaged, which affects the efficiency of the gear's use and installation. Therefore, it is necessary to propose a detachable wear-resistant gear based on double-joint molding to solve the above-mentioned problems. Utility Model Content

[0024] Rotate the rotating shaft 12, the rotating shaft 12 will drive the second gear body 4 and the assembly shaft 3 to rotate. When the assembly shaft 3 rotates, it will synchronously drive the first limiting protrusion 801 and the second limiting protrusion 802 to be offset from the inside of the plug-in groove 805 at the same time. The plug-in groove 805 is connected with the first annular groove 803 and the second annular groove 804. The first limiting protrusion 801 and the second limiting protrusion 802 will radially slide to the inside of the first annular groove 803 and the second annular groove 804 respectively.

[0025] The first limiting protrusion 801 and the second limiting protrusion 802 are limited by the first annular groove 803 and the second annular groove 804 to limit the assembly shaft 3, so that the second gear body 4 and the first gear body 1 are assembled and installed, the assembly steps are simple and the assembly efficiency is high.
