Description

Technical Field

[0001] The present invention relates to the technical field of speed reducer direction control transmission, and in particular to an internal meshing RV speed reducer for an industrial robot. Background Art

[0002] RV reducer is a reducer with a special transmission method. It has the characteristics of compact structure, smooth transmission and high efficiency. It is widely used in industrial automation, robots, machine tools, conveyor belts, lifting machinery and other fields.

[0003] There are many types of RV reducers available today, such as the steering transmission device for RV reducers disclosed in publication number CN118149059B. This device achieves steering by rotating a connecting gear that engages with a first gear shaft and a second gear shaft, respectively. However, while the connecting gear is driven to rotate and engage with the second gear shaft, it remains stationary. During this process, the tooth grooves of the connecting gear are likely to misalign with the second gear shaft. When the tooth grooves are misaligned, the contact surfaces between the gears slip, increasing friction. This abnormal friction can cause wear on the gear surfaces, especially under high loads or high speeds, where wear is more severe and can affect the efficiency and lifespan of the entire transmission. Summary of the Invention

A nozzle is fixedly installed at the lower end of the oil inlet box 503, and the nozzle penetrates through the second oil box 502 and extends into its interior.

[0024] The working principle of the present invention is as follows: First, commutation: During the process of the reduction gear 1 driving the output main shaft 301 to rotate, the output main shaft 301 drives the transmission shaft 303 to rotate through the meshing transmission gear pair 302. The rotating transmission shaft 303 drives the long shaft 305, the first transmission gear 307, and the second transmission gear 308 to rotate together. The rotating first transmission gear 307 drives the first driven gear 402 to rotate together. The rotating first driven gear 402 drives the rotating main shaft 401 to move forward. At this time, the rotating long shaft 305 also drives the second transmission gear 308 to rotate. The rotating second transmission gear 308 meshes with the pinion 405 to drive the second driven gear 403 to rotate on the outer wall of the rotating main shaft 401. When the rotating main shaft 401 is driven to rotate forward, the second driven gear 403 is driven to rotate reversely on the outer wall of the rotating main shaft 401. At the same time, the second transmission gear 308 and the pinion 405 always remain in a meshing state; When reverse rotation is required, the rotating drive member 315 is opened to drive the screw 314 to rotate. The moving block 316 in rotation drives the rotating ring 309 and the rotating sleeve 304 to move through the rotating collar 310, causing the rotating sleeve 304 to slide on the outer wall of the transmission shaft 303. When the rotating collar 310 is driven to move, the two connected electrical contacts 311 are disconnected, and the connected electrical contacts 311 stop supplying power to the electromagnetic clutch 306, causing the clutch disc to lose magnetism and stop adsorbing to the long shaft 305. The moving rotating sleeve 304 drives the long shaft 305, the first transmission gear 307, and the second transmission gear 308 to move together. Due to the large width of the first transmission gear 307, it still meshes with the first driven gear 402 when driven to move; When the rotating sleeve 304 is driven to move, it drives the snap ring 419 to move together. The snap ring 419 contacts and presses the runner 415, and the vertical plate 414 and the moving plate 413 move in the fixed frame 412. The moving moving plate 413 compresses the second spring 416 and drives the moving rod 417 to press the hydraulic oil provided in the hydraulic chamber, increasing the hydraulic pressure of the hydraulic oil. The hydraulic oil with increased hydraulic pressure drives the disc 410 and the ejector rod 408 to slide in the inner groove 418 and compresses the third spring 420. The tapered head provided at one end of the ejector rod 408 contacts and presses the top block 409, and the top block 409 slides in the short rod 404. The top block 409 slides into the second driven gear 403. After the provided electromagnetic clutch 306 stops adsorbing to the outer wall of the long shaft 305, the rotating force of the long shaft 305 drives the pinion 405 and the second driven gear 403 to rotate through the second transmission gear 308. At this time, the rotating second driven gear 403 drives the rotating main shaft 401 to rotate reversely during rotation because the top block 409 slides into its interior; When driving the rotating main shaft 401 to rotate forward and backward, the first transmission gear 307 and the second transmission gear 308 are respectively engaged with the first driven gear 402 and the second driven gear 403 for rotation. During the forward rotation, the first transmission gear 307 is engaged with the first driven gear 402 for transmission, and the second transmission gear 308, the pinion gear 405 and the second driven gear 403 remain engaged and in a non-transmission state. During the reverse rotation, the second transmission gear 308 is engaged with the pinion gear 405 and the second driven gear 403 for transmission, and the first transmission gear 307 and the first driven gear 402 remain engaged and in a non-transmission state. This can effectively avoid the wear caused by the tooth grooves not being aligned when the gears are engaged; Second, lubrication: During the process of gear meshing transmission, it is usually necessary to inject lubricating oil for lubrication. The main function of the lubricating oil is to form an oil film to reduce the direct contact and friction between the gears. However, if the amount of lubricating oil is insufficient or the oil film is not completely formed due to oil degradation, the friction between the gears will increase. The increase in friction force will not only accelerate the wear of the gears, but also generate more heat, which will lead to overheating; With the first semiconductor chip 506, the second semiconductor chip 507, and the second semiconductor chip 507 provided, when the lubricating oil between the gears in the first oil cartridge 501 and the second oil cartridge 502 is insufficient in quantity or deteriorates in quality, the temperature in the first oil cartridge 501 and the second oil cartridge 502 will rise. The first semiconductor chip 506 and the second semiconductor chip 507 provided in the first oil cartridge 501 and the second oil cartridge 502 will be heated by the increased temperature. Through the thermoelectric effect, when the first semiconductor chip 506 and the second semiconductor chip 507 are heated, a temperature difference will be formed with the third semiconductor chip 508. The formed temperature difference will generate a voltage in the series circuit. The provided relay 509 will sense the generated voltage and control the external power supply to deliver voltage to the rotating motor 510, driving the rotating motor 510 to rotate. The rotating rotating motor 510 will drive the auger rotating shaft 512 to rotate in the conveying barrel 511. Then, the external oil pump is turned on to convey part of the lubricating oil into the oil inlet cartridge 503 through the connection port 514. Part of the hydraulic oil entering the oil inlet cartridge 503 will be sprayed into the second oil cartridge 502 from the nozzle to lubricate the first transmission gear 307, the second transmission gear 308, the first driven gear 402, and the second driven gear 403. Another part of the hydraulic oil will enter the first oil cartridge 501 through the conveying pipe 504 to lubricate the meshing transmission gear pair 302 and reduce the temperature in the first oil cartridge 501 and the second oil cartridge 502. The lubricating oil falling to the bottom end of the first oil cartridge 501 will flow into the second oil cartridge 502 through the transfer pipe 505. The rotating auger rotating shaft 512 will re-convey the lubricating oil accumulated in the second oil cartridge 502 back to the oil inlet cartridge 503 through the return pipe 513, so as to perform circulating lubrication and cooling. When the temperature difference between the first semiconductor chip 506, the second semiconductor chip 507, and the third semiconductor chip 508 provided in the first oil cartridge 501 and the second oil cartridge 502 decreases to be consistent, the voltage in the series circuit disappears, and the relay 509 disconnects the voltage supplied to the rotating motor 510. The temperature of the equipment in the first oil cartridge 501 and the second oil cartridge 502 decreases and the lubrication effect is obtained.
