Description

Technical Field

[0001] This invention relates to the field of harmonic reducer technology, specifically to a harmonic reducer with a flat double circular tooth steel wheel and bearing. Background Technology

[0002] Harmonic drive reducers are gear transmissions that rely on a wave generator fitted with a flexible bearing to cause the flexible gear to produce controllable elastic deformation, which then meshes with a rigid gear to transmit motion and power.

[0032] Please see Figure 1 , Figure 4 , Figure 5 and Figure 8 A harmonic reducer with a flat double circular tooth steel wheel and bearing;

[0033] The system includes a wave generator 1, a flexible gear 2 connected to the surface of the wave generator 1, a rigid gear 3 connected to the surface of the flexible gear 2, a placement cavity 4 inside the wave generator 1, an oil storage tank 5 inside the placement cavity 4, an oil supply cavity 6 inside the placement cavity 4, a first oil supply pipe 7 on the inner top wall of the oil supply cavity 6, a first control valve 8 on the surface of the first oil supply pipe 7, a metering cavity 9 at the bottom end of the first oil supply pipe 7, a first touch switch 10 on one side of the inner top wall of the metering cavity 9, and the first touch switch 10 is electrically connected to the first control valve 8, a vertical plate 11 on one side of the inner top wall of the metering cavity 9, a support base on one side of the inner bottom wall of the metering cavity 9, a second touch switch 12 on the top of the support base, a ball valve 13 inside the metering cavity 9, and a second oil supply pipe 14 on one side of the bottom of the metering cavity 9. A second control valve 15 is provided on the surface of the oil supply pipe 14. A through hole 17 is provided on the back of the placement cavity 4. An oil outlet pipe 16 passes through the through hole 17, and the bottom end of the second oil supply pipe 14 is fixedly connected to the surface of the oil outlet pipe 16. A first rack 32 is provided on the surface of the flexible gear 2, and a second rack 27 is provided on the inner wall of the rigid gear 3. The surfaces of the first rack 32 and the second rack 27 mesh with each other. An oil leakage hole 29 is provided on the inner wall of the flexible gear 2, and the surface of the oil leakage hole 29 passes through the interior of the first rack 32. When the operator opens the first control valve 8, the first control valve 8 opens the first oil supply pipe 7, allowing the first oil supply pipe 7 to deliver the lubricant inside the oil storage tank 5 to the interior of the metering cavity 9. At this time, the ball valve 13 inside the metering cavity 9 rises continuously as the amount of lubricant inside increases, until the ball valve 13... When the surface of the device touches the first touch switch 10, the first touch switch 10 controls the first control valve 8 to close, thereby stopping the first oil supply pipe 7 from supplying oil to the metering chamber 9. At this time, the operator controls the first control valve 8 to open, causing the second control valve 15 to open the second oil supply pipe 14, thereby stopping the metering chamber 9 from supplying oil. The internal lubricant flows into the interior of the oil outlet pipe 16 through the second oil supply pipe 14, allowing the oil outlet pipe 16 to deliver the lubricant to the interior of the flexible gear 2. It then passes through the oil drain hole 29 to the surface of the first rack 32. After the first rack 32 meshes with the surface of the second rack 27, the lubricant is transferred from the first rack 32 to the second rack 27. After multiple transmissions, a certain lubrication effect is achieved between the first rack 32 and the second rack 27, resulting in better transmission performance. The placement cavity 4 facilitates the placement of the oil storage tank 5. The first oil supply pipe 7, the first control valve 8, and the first touch switch 10 facilitate the entry of lubricant from the oil storage tank 5 into the metering chamber 9. Simultaneously, when the metering chamber 9 is full, the first control valve 8 automatically closes, stopping the oil supply to the metering chamber 9. The second control valve 15, the second oil supply pipe 14, and the oil outlet pipe 16 facilitate the entry of lubricant into the flexible gear 2. The oil drain hole 29 further enhances the lubricant's role in the transmission process.This allows the lubricant to flow more easily to the surfaces of the first rack 32 and the second rack 27, thereby improving the transmission effect.

[0034] Please see Figure 1 , Figure 3 , Figure 6 and Figure 7 A harmonic reducer with a flat double circular tooth steel wheel and bearing;

[0035] The wave generator 1 has a connecting ring 18 inside, and the surface of the placement cavity 4 is in contact with the inner wall of the connecting ring 18. The inner wall of the connecting ring 18 has a set of sliding grooves 19, and the sliding grooves 19 have vertical grooves 20 inside. The connecting ring 18 has a set of telescopic cylinders 21 inside, and the output end of the telescopic cylinders 21 has a baffle 22. The inner wall of the vertical groove 20 has a hollow groove, and the surface of the baffle 22 extends through the hollow groove. The surface of the placement cavity 4 is equipped with a set of sliding blocks 23, which slide within the sliding grooves 19 and the vertical grooves 20. The surface of the placement cavity 4 is connected to a transmission disc 24, and the surface of the transmission disc 24 is equipped with a set of fixing blocks 25. The internal threaded connection of the device is a fastening bolt 26, the surface thread of the fastening bolt 26 penetrates the interior of the placement cavity 4. The placement cavity 4 contains a set of connecting cavities 28, and the surface thread of the fastening bolt 26 penetrates the interior of the connecting cavities 28. The wave generator 1 contains a flexible bearing 30. The operator controls the telescopic cylinder 21 to move back, causing the telescopic cylinder 21 to move the baffle 22 downwards, stopping its obstruction of the sliding block 23. At this time, the operator rotates the placement cavity 4, allowing it to slide through the vertical groove 20 until it slides into the sliding groove 19. Then, the operator pulls it outwards, causing the placement cavity 4 to slide outwards through the sliding block 23 on its surface, thus removing the entire placement cavity 4. Then, the fastening bolt 26 is removed from... The internal parts of the placement cavity 4 are unscrewed, causing the fastening bolt 26 to separate from the connecting cavity 28, and thus the transmission disc 24 to separate from the placement cavity 4. This allows the entire device to be quickly disassembled for easy maintenance. The sliding block 23 and the sliding groove 19 facilitate the entry of the placement cavity 4 into the connecting ring 18. The vertical groove 20 provides a certain limiting effect for the placement cavity 4, preventing it from sliding outward. The telescopic cylinder 21, the baffle 22, and the empty groove limit the sliding block 23 within the vertical groove 20, thereby ensuring the stability of the placement cavity 4 within the connecting ring 18. The fastening bolt 26, the fixing block 25, and the connecting cavity 28 facilitate the installation and disassembly of the transmission disc 24, making it easy to repair if damaged.

[0036] Please see Figure 1 and Figure 5 A harmonic reducer with a flat double circular tooth steel wheel and bearing;

[0037] An alarm 31 is installed on the surface of the transmission disc 24, and the alarm 31 is electrically connected to the second touch switch 12. After the second oil supply pipe 14 delivers lubricant into the oil outlet pipe 16, it is then output through the oil outlet pipe 16. When the lubricant in the metering chamber 9 reaches a certain amount, the lubricant level decreases. At this time, the ball valve 13 descends accordingly, causing the ball valve 13 to touch the second touch switch 12. This causes the second touch switch 12 to transmit a signal to the alarm 31, which then sounds an alarm. The alarm 31 promptly reminds the operator that the lubricant in the metering chamber 9 is insufficient, facilitating the operator to add more lubricant. The second touch switch 12 ensures that the lubricant level in the metering chamber 9 is maintained within a certain range. After the flow is complete, a signal is promptly sent to the alarm 31. The alarm 31 is set up to remind the surrounding staff in a timely manner, making it convenient to add lubricant to its internal parts. The wave generator 1, flexible gear 2, and rigid gear 3 achieve a high reduction ratio and are all located on the same shaft. The kit is easy to install and has a simple design. At the same time, the sliding of the meshing parts of the flexible gear 2 and rigid gear 3 is very small, reducing the power loss caused by friction. Therefore, while achieving a high reduction ratio, high efficiency is maintained. The flexible gear material uses a special steel with high fatigue resistance, which is different from ordinary transmission devices. At the same time, the number of meshing teeth accounts for about 30% of the total number of teeth, and it is a surface contact. Therefore, the pressure on each gear is reduced, and a high torque capacity can be obtained.

[0038] Working principle: The operator opens the first control valve 8, which opens the first oil supply pipe 7, allowing the lubricant in the oil storage tank 5 to be delivered to the metering chamber 9. As the amount of lubricant inside the metering chamber 9 increases, the ball valve 13 rises until its surface touches the first touch switch 10. The first touch switch 10 then closes the first control valve 8, stopping the first oil supply pipe 7 from supplying oil to the metering chamber 9. The operator then opens the first control valve 8, causing the second control valve 15 to open the second oil supply pipe 14, allowing the lubricant in the metering chamber 9 to flow through the second oil supply pipe 14 into the outlet pipe 16. The outlet pipe 16 delivers the lubricant to the flexible gear 2, and then through the oil drain hole 29 to the surface of the first rack 32. After the first rack 32 meshes with the surface of the second rack 27, the lubricant is transferred from the first rack 32 to the second rack 27. This process continues multiple times until the first rack 32... The second rack 27 provides lubrication, resulting in better transmission. The operator controls the telescopic cylinder 21 to move back, causing the baffle 22 to move downwards, stopping its obstruction of the sliding block 23. At this point, the operator rotates the placement cavity 4, allowing it to slide through the vertical groove 20 until it reaches the inside of the sliding groove 19. The operator then pulls it outwards, causing the placement cavity 4 to slide outwards via the sliding block 23 on its surface, thus removing the entire placement cavity 4. Finally, the fastening bolt 26 is unscrewed from inside the placement cavity 4, allowing the fastening bolt 26 to connect with the connecting cavity 28. Separation allows the transmission disc 24 to separate from the placement cavity 4, making the entire device easy to disassemble quickly and convenient for maintenance. After the second oil supply pipe 14 delivers lubricant to the oil outlet pipe 16, it is then output through the oil outlet pipe 16. When the lubricant in the metering cavity 9 reaches a certain amount, the amount of lubricant inside decreases. At this time, the ball valve 13 follows and descends, causing the ball valve 13 to touch the second touch switch 12. The second touch switch 12 then transmits a signal to the alarm 31, causing the alarm 31 to sound an alarm. The alarm 31 promptly reminds the staff that the lubricant in the metering cavity 9 is insufficient, making it convenient for the staff to add more lubricant. The setting of the second touch switch 12 makes it easy to send a signal to the alarm 31 in a timely manner after the lubricant in the metering cavity 9 has finished flowing.
