Description

Technical Field

[0001] The utility model relates to the technical field of worm wheels, in particular to a copper worm wheel with an anti-dropping structure. Background Technique

[0002] A copper worm wheel is a mechanical structure that uses the spiral line of a worm for gear transmission. It has high wear resistance and strength and can resist high pressure and high-temperature wear. The copper worm wheel has good self-lubricating performance, which can reduce the wear between mechanical parts and improve the service life of the entire mechanical system. The production of a copper worm wheel requires the use of numerical control processing equipment to ensure technical indicators such as the accuracy of its geometric shape and the smoothness of its surface. During use, problems such as wear and aging will occur to the copper worm wheel, and regular maintenance and replacement are required. At the same time, during daily use, it is also necessary to pay attention to keeping the surface of the copper worm wheel clean and lubricated to prevent problems such as excessive wear and corrosion, so as to extend its service life. The copper worm wheel is widely used in the modern industrial field and is a very important mechanical part.

[0003] For a joint structure of a copper worm wheel with the Chinese authorized announcement number of CN 220850650 U, a welding groove is provided between the wheel core component and the wheel rim component, and a highly compatible welding material is filled, and the two are organically connected with the welding material to ensure performance such as strength. Moreover, the interference fit between the wheel core component and the wheel rim component can transmit torque, and the overall load-bearing capacity is stronger.

[0004] However, there are still some deficiencies in the use of this patent. The existing connection method between the worm wheel and the worm shaft is generally to use a welding material for welding and fixing. The worm shaft and the worm wheel body are an integral structure. However, the integral structure has relatively high requirements for the processing accuracy of the worm wheel itself. Moreover, the worm shaft and the worm wheel body of the integral structure may generate a large axial force during operation, resulting in easy heating, which in turn affects the transmission efficiency. During long-term use, the service life may be shortened due to problems such as stress concentration and material fatigue. In addition, the existing worm wheel has a large self-weight, which may cause the worm wheel to run unstably, increase vibration and noise, and may affect the surrounding equipment.

[0028] In this embodiment, as shown in Figure 1 , Figure 2 , Figure 3 and Figure 4 , the worm wheel shaft 1 includes a shaft rod 101, a connecting part 102 is fixedly connected to the outside of the shaft rod 101, several limiting grooves 103 are opened on the side of the connecting part 102, several limiting blocks 104 are arranged on the outside of the shaft rod 101, the side of the limiting block 104 is fixedly connected to the connecting part 102, a first threaded part 105 is arranged on the outside of the shaft rod 101, the worm wheel body 2 includes a hub 201, a mounting groove 207 is opened on the side of the mounting part 204, a positioning groove 205 and a threaded hole 206 are respectively opened inside the mounting part 204, an abutting groove 208 is opened on the side of the mounting part 204, the reinforcing member 3 includes a support plate 301, a convex block 302 is arranged on the side of the support plate 301, and a second threaded part 303 is arranged inside the support plate 301, and the second threaded part 303 is threadedly connected with the first threaded part 105.

[0029] Among them, by setting the worm wheel shaft 1, the worm wheel body 2 and the reinforcement 3, the worm wheel is set as a split structure, making its connection tight and easy to disassemble.
