Description

Technical Field

[0002] A worm is a gear with one or more spiral teeth that meshes with a worm wheel to form a staggered gear pair. Its pitch surface can be a cylindrical surface, a conical surface, or a torus surface. The appearance of a worm is similar to that of a bolt, but its tooth surface is spiral, and it meshes with the spiral teeth of the worm wheel to achieve power transmission. Worm transmission usually has a large transmission ratio, a compact structure, and is self-locking under certain conditions. When in use, the worm needs to rotate frequently as a driving component to rotate the worm wheel, so the worm usually has a high strength.

[0003] When the existing high-strength drive worm is used, the worm is installed on a bearing seat with a bearing, one end of the worm is connected to a drive source such as a drive motor, and then it is used. However, in the existing high-strength drive worm, the worm is an integral structure. After long-term use, the transmission part of the worm will still wear out and need to be replaced. At this time, since the main part of the worm used for transmission cannot be disassembled separately, the entire worm needs to be disassembled and replaced. It is not possible to quickly disassemble the corresponding parts for replacement, and the replacement cost of the entire worm will increase, and the operation flexibility is poor.

When using a high-strength driving worm, the driving source runs through the first connecting component 6 to rotate with the mounting sleeve 1 and the worm body 2. Under the driving action of the worm body 2, the worm wheel starts to rotate, thereby realizing the worm gear drive. When necessary, the first connecting component 6 and the second connecting component 7 can be moved, so that the two connecting components are pulled out of the through hole 3, and then the part of the worm body 2 can be replaced. The structure is simple and the operation is convenient. The fixing screw 5 can also be loosened to fine-tune the relative position of the worm body 2 so that it can better mesh with the worm wheel, thereby improving the transmission stability and accuracy.

[0020] According to the above implementation scheme, the first connecting component 6 includes a first rotating shaft 601, a first positioning groove 602 and a hexagonal groove 603, the first positioning groove 602 is arranged on the first rotating shaft 601, and the hexagonal groove 603 is arranged at the end of the first rotating shaft 601.
