Description

Technical Field

[0001] The invention relates to the technical field of reducer lubrication, in particular to an internal lubrication self-supply oil system for a double worm gear reducer. Background Art

[0002] Due to the special internal structural characteristics of the twin-worm gear reducer, the lubricating oil tank is located at the bottom of the worm gear housing, and the large worm gear is located at the top of the twin-worm gear reducer. Therefore, the lubrication of the bearings and the small worm gear inside the worm gear housing needs to be solved. Generally, the large worm gear oil of the reducer is immersed in the worm housing, and the lubrication problem of the bearings and the worm gear meshing is relatively easy to solve. However, the worm gear reducer is limited by the overall structure of the AOD system and adopts a lower worm gear structure, which makes lubrication relatively difficult. Therefore, a self-lubricating oil supply system is required. Secondly, due to friction and wear at the contact point between the worm wheel and the worm, metal particles will fall off to form wear particles. These particles will be suspended in the lubricating oil and become impurities. The impurities in the lubricating oil will increase friction and reduce the lubrication effect. Direct recycling will cause secondary wear. In response to the above problems, the inventor proposes an internal lubrication self-supply oil supply system for a twin-worm gear reducer to solve the above problems. Summary of the invention

[0033] By adopting the above technical solution, the filter chamber 601 is connected with the oil supply chamber 506 .

[0034] Working principle: First, Figure 1 As shown, the small worm 401 is fixedly connected to the input shaft of the external motor, the external motor drives the large worm 402 to rotate through the small worm 401 and the small worm wheel 403, and the large worm 402 drives the output shaft 404 to rotate through the large worm wheel 405. The deceleration effect is achieved through the coordinated cooperation between the worm wheels and the worm gears. During the rotation of the large worm 402, the cam 501 is driven to rotate synchronously. Under the stretching action of the oil drawing wire 505, the roller 504 on the rocker 503 is tightly attached to the outer wall of the cam 501. As the cam 501 rotates, the rocker 503 is driven to swing back and forth with the rotating connection of the fixed plate 502 as the axis. During the swinging process of the rocker 503, the oil drawing wire 505 is driven to move up and down, as shown in FIG. Figure 5 , Figure 6 As shown, when the oil supply wire 505 moves upward, the driving piston 507 is pulled upward, and the internal spring 508 is deformed by tension, which generates a force in the opposite direction on the driving piston 507. Due to the lifting of the driving piston 507, the pressure inside the oil supply chamber 506 is reduced, thereby forcing the lubricating oil liquid gathered at the bottom of the filter bin 601 to be pressed in through the oil inlet pipe 514 and the oil inlet one-way valve 510. At the same time, the lubricating oil liquid in the oil supply chamber 506 is prevented from flowing back by the oil outlet one-way valve 509. When the driving piston 507 is lifted to the highest point, the lubricating oil liquid fills the oil supply chamber 506, and the pressure is restored to balance. The pulling force of the oil supply wire 505 and the internal spring 508 on the driving piston 507 is balanced. At this time, the connection point between the top cam 501 and the rocker arm 503 and the oil supply wire 505 begins to descend. , the pulling force of the oil drawing wire 505 on the driving piston 507 decreases, and the built-in spring 508 begins to pull the driving piston 507 downward, and the pressure in the oil supply chamber 506 increases, thereby forcing the lubricating oil to be pressed into the oil outlet pipe 511 through the oil outlet one-way valve 509. At the same time, the lubricating oil in the oil supply chamber 506 is prevented from being squeezed back into the filter bin 601 by the oil inlet one-way valve 510. The lubricating oil rises to the top along the oil outlet pipe 511 and enters the two oil drain pipes 512 respectively, and falls to the corresponding large worm 402 meshing part, the small worm 401 meshing part and the intermediate bearing through the oil drip hole 513 opened at the bottom of the oil drain pipe 512, thereby achieving the effect of drip lubrication, and the lubricating oil in the lubrication part can flow back to the bottom frame 204 through the overflow port of the oil storage bay inside the housing protection component 2 or naturally drip and gather; In the initial state, lubricating liquid is collected in the bottom frame 204 and the filter chamber 601, and the lubricating oil level in the filter chamber 601 is higher than the oil inlet pipe 514. Figure 7 As shown, when the lubricating oil at the bottom of the filter tank 601 enters the oil supply chamber 506 through the oil inlet pipe 514, the pressure in the filter tank 601 decreases, thereby forcing the lubricating oil accumulated in the bottom frame 204 to Figure 4 As shown, the oil enters the upper part of the filter bin 601 through the connecting pipe 615, and passes through three filter papers 608 in sequence to filter the impurities inside the lubricating oil. The filtered lubricating oil flows into the bottom of the filter bin 601 through the rectangular groove in the built-in plate 603 and gathers. At this point, the reducer lubrication self-supply oil system completes an oil pump cycle without external force drive; When the filter paper 608 in the filter chamber 601 needs to be replaced, the plug 704 is manually pulled up to completely separate the plug 704 from the side door 702, and then the side door 702 is opened. The top bolt of the sealing cover 602 is removed by a wrench, and the sealing cover 602 is taken out. Fig. 9 As shown, the synchronization frame 613 is manually pushed to move toward the side of the filter frame 606, the reset spring 614 is deformed by tension, and the synchronization frame 613 pushes the two limiting bow bolts 610 in the slide groove 611. The protrusion of the limiting bow bolt 610 corresponds to the filter frame 606. At this time, the limiting bow bolt 610 stops limiting the filter frame 606. The three filter frames 606 are taken out in turn, and the new filter frame 606 is inserted into the corresponding card slot 605 through the slot 607. At this time, the bottom of the filter frame 606 is completely inserted into the limiting slot 609, loosen the synchronization frame 613, and under the action of the reset spring 614, drive the two limiting bow bolts 610 to reset and limit the filter frame 606. After the filter frame 606 and the filter paper 608 are replaced, the sealing cover 602 is fixed and sealed to the filter bin 601 by bolts. When the side door 702 is opened, the oil drawing wire 505 can be adjusted by the screw buckle 515. Finally, pull up the plug 704 to close the side door 702 and insert the plug 704 into the corresponding slot of the side door 702.
