Description

Technical Field

[0001] The utility model relates to the technical field of general machinery, in particular to a combined general machinery connecting shaft. Background Art

[0002] General machinery refers to mechanical equipment with strong versatility and wide application. General machinery generally refers to pumps, fans, compressors, valves, gas separation equipment, vacuum equipment, separation machinery, speed reducers, drying equipment, gas purification equipment or acetylene dissolution equipment, etc. Couplings are a commonly used transition connection method in mechanical transmission to absorb vibration and compensate for radial and angular deviations.

[0003] Existing combined general-purpose mechanical connecting shafts, such as a high-strength combined connecting shaft for general-purpose machinery disclosed in Chinese patent application CN214197020U, record: the high-strength combined connecting shaft for general-purpose machinery, through the upper shaft cylinder, upper clamping block, upper spring leaf, upper fixing nut, upper connecting block, first compression spring, movable block, protective sleeve, lower shaft cylinder, lower clamping block, lower spring leaf, lower fixing nut, lower connecting block, second compression spring and locking block, can achieve the high-strength combined connecting shaft will not rotate with the inertial movement of the output end when in use, avoid the motor shaft from rotating reversely inside the motor, extend the service life of the motor, bring convenience to the work of the staff, improve the work efficiency of the staff, reduce people's economic losses, reduce people's capital cost investment, solve the problem that the general high-strength combined connecting shaft will rotate with the inertial movement of the output end, thereby facilitating people's work and life.

[0004] When the above-mentioned combined general-purpose mechanical connecting shaft is used in combination, lubricating oil needs to be added to reduce the friction of the shaft cylinder. After the shaft cylinder is installed, it is difficult to replenish the lubricating oil inside. The lubricating oil will gradually lose its lubricating properties during use, resulting in increased wear of the internal parts of the connecting shaft. Failure to replace the lubricating oil for a long time will lead to an increase in the frequency of equipment failures, thereby increasing maintenance costs. Once the equipment fails, it is inconvenient to disassemble and assemble during maintenance, and long downtime is required for maintenance and replacement of parts, which will increase the company's operating costs.

Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The utility model is further described below in conjunction with embodiments.

[0025] Example 1

[0026] Reference Figure 1-3 , which is the first embodiment of the utility model, provides a combined universal mechanical connecting shaft, which includes a fixed shaft 100, a replacement mechanism 200 sleeved on one side of the fixed shaft 100, and the replacement mechanism 200 includes a sleeve 201, a fixed slide 202, a sliding rod 203, a return spring 204 and a limit groove 205, one end of the sleeve 201 is slidably connected to the fixed shaft 100, and the fixed slide 202 is slidably connected to one end of the sleeve 201. At the end, the sliding rod 203 is slidably connected to the sleeve 201, and the return spring 204 is sleeved on the sliding rod 203. The limiting grooves 205 are opened on both sides of the sleeve 201. By pulling the fixed slide 202 to slide toward the end away from the fixed axis 100, the sliding rod 203 slides along the limiting groove 205 into the adjusting groove 206, which plays a limiting role and squeezes the return spring 204. When the fixed slide 202 is released, the return spring 204 rebounds and pushes the fixed slide 202 back.

[0027] An adjustment slot 206 is provided on one side of the limiting slot 205 . The return spring 204 is arranged in the limiting slot 205 . The return spring 204 is slidably connected in the limiting slot 205 . The sliding rod 203 is slidably connected in the limiting slot 205 .

[0028] One end of the sleeve 201 is fixedly connected to a fixing block 207, and one end of the sleeve 201 is fixedly connected to a connecting block 208. The fixing block 207 and the connecting block 208 are symmetrically installed at one end of the sleeve 201. The opening on the fixing block 207 penetrates the fixing block 207, and the opening on the connecting block 208 penetrates the connecting block 208.

[0029] A through hole 209 is opened on the fixed shaft 100, and a fixed rod 210 is slidably connected inside the fixed shaft 100. By aligning the through hole 209 on the fixed shaft 100 with new lubricating oil added with the fixed block 207 and the connecting block 208 on the sleeve 201, the fixed rod 210 is inserted into the through hole 209 along the connecting block 208 into the fixed block 207, which plays a role of fixing and limiting.

[0030] During use, by pulling the fixed slide 202 to slide toward the end away from the fixed shaft 100, the sliding rod 203 slides along the limit groove 205 into the adjustment groove 206, which plays a limiting role, squeezes the return spring 204, and removes the fixed rod 210 from the through hole 209 along the connecting block 208. When the fixed slide 202 is released, the return spring 204 rebounds to push the fixed slide 202 back, which is convenient for replacement and maintenance. When the mechanical equipment fails or requires regular maintenance, the ability to quickly disassemble and install the connecting shaft can greatly improve maintenance efficiency, reduce downtime, and thus save maintenance costs.

[0031] Example 2

[0032] Reference Figure 1-4 , which is the second embodiment of the utility model, provides a combined universal mechanical connecting shaft, which includes a fixed slide 202 with a limiting slide groove 211 on one side, and a fixed rod 210 is arranged in the limiting slide groove 211. When the fixed rod 210 is inserted into the through hole 209, the fixed slide 202 slides through the limiting slide groove 211 to limit the fixed rod 210 to prevent the fixed rod 210 from falling off.

[0033] A sealing V-ring 212 is embedded in the sleeve 201, and a scraper 213 is fixedly connected inside the sleeve 201. A lubrication chamber 214 is opened at one end of the fixed shaft 100. By rotating the fixed shaft 100 one circle, the scraper 213 scrapes the old lubricating oil in the lubrication chamber 214 together, and the fixed shaft 100 is moved to the right, and the vertical scraper at one end of the scraper 213 scrapes the old lubricating oil in the lubrication chamber 214 out of the lubrication chamber 214.

[0034] During use, by rotating the fixed shaft 100 one circle, the old lubricating oil in the lubrication chamber 214 is scraped together by the scraper 213, and the fixed shaft 100 is moved to the right. The old lubricating oil in the lubrication chamber 214 is scraped out of the lubrication chamber 214 by the vertical scraper at one end of the scraper 213, so that the old lubricating oil in the lubrication chamber 214 can be cleaned and replaced conveniently. The new lubricating oil has better fluidity and lubricity, can provide better lubrication effect, reduce the friction resistance of the connecting shaft during operation, and thus improve the working efficiency of the connecting shaft.

[0035] The remaining structure is the same as that of Example 1.
