Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of gears, in particular to a gear which is easy to disassemble, assemble and replace. Background Art
[0002] Gears are mechanical transmission components that transmit power and torque through tightly meshed teeth. Gears are widely used in various mechanical transmission systems, such as automobiles, machine tools, and electric machinery. During gear transmission, the teeth collide and squeeze against each other, causing wear and damage. This damage can lead to loss of precise transmission, necessitating complete gear replacement, resulting in high repair costs. However, traditional mounting methods are inconvenient for replacement. Therefore, a gear design that is easily disassembled and replaced is needed to address this issue. Utility Model Content
[0003] The purpose of this application is to provide a gear that is easy to disassemble, assemble and replace, so as to solve the problems raised in the above background technology.
[0004] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a gear that is easy to disassemble and replace, comprising a gear body, a mounting structure, the mounting structure comprising a mounting shaft, a fixing plate, a fixing bolt, and a fixing structure, the interior of the gear body is provided with a mounting shaft fixedly mounted on its inner wall, one end of the mounting shaft contacts the fixing plate, one side of the fixing plate is provided with a plurality of fixing bolts, each of the fixing bolts is sequentially threadedly connected to the fixing plate, the gear body, the mounting shaft, the inner cavity top and the inner cavity bottom of the gear body are both provided with a fixing structure, the fixing structure comprises a limiting A positioning groove, a limiting block, a limiting rod, a limiting plate, a return spring, a limiting cavity, and an anti-slip plate. The top and bottom of the mounting shaft are provided with a limiting groove, and a limiting block is provided inside each of the limiting grooves. One end of each limiting block is fixedly connected to the limiting rod, and a return spring is provided below each limiting block that is sleeved with the limiting rod. Each limiting rod is slidably connected to the limiting plate. The top and bottom ends of the inner cavity of the gear body are provided with a limiting cavity, and both sides of each limiting plate are fixedly connected to the inner wall of the limiting cavity. One end of each limiting rod is fixedly connected to an anti-slip plate.
[0005] Preferably, the two fixing structures are symmetrically arranged.
[0006] Preferably, one end of the fixing bolt is threadedly connected to a fixing plate and a mounting shaft.
[0007] Preferably, the top end of each of the return springs contacts the limit block, and the bottom end of each of the return springs contacts the limit plate.

[0011] In summary, the technical effects and advantages of the present utility model are as follows:
[0012] In the present utility model, the gear main body and the mounting shaft are fixed for the first time through the fixing structure. When the mounting shaft slowly enters the inside of the gear main body, the limiting block will be squeezed. The limiting block compresses the return spring and pushes the limiting rod to move towards the inside of the limiting cavity. When the limiting groove on the mounting shaft moves to a position corresponding to the limiting block, the return spring will push the limiting block and push it into the limiting groove to complete the installation. This structure is convenient for installation and disassembly. Then, the fixing plate and the fixing bolts are installed on the mounting shaft.
