Description

Technical Field

[0001] This invention relates to the field of speed reducer technology, and more specifically, to a speed reducer based on equal-strength multi-point meshing planetary transmission. Background Technology

[0002] A planetary reducer is a power transmission mechanism that uses multiple planetary gears rotating around a sun gear to reduce the speed of a motor to the desired speed and obtain a larger torque, thereby achieving the purpose of speed reduction.

[0003] Patent application publication number CN114992288B discloses a planetary reducer with flexible transmission, belonging to the technical field of planetary reducers. It includes a housing, an input main shaft rotatably mounted on the housing for connecting a drive motor shaft and an output main shaft for connecting a load, a transmission sleeve with one end non-contactly fitted onto the input main shaft and the other end rotatably mounted on the output main shaft, a transmission spring mounted inside the transmission sleeve and fitted onto the input main shaft, a sun gear fixedly mounted on the transmission sleeve, a planet carrier fixedly mounted on the output main shaft, planet gears A and B rotatably mounted on the planet carrier and meshing with the sun gear, and a flexible double-sided gear ring capable of significant elastic deformation. This invention is a planetary reducer with a reasonable structure, featuring a flexible start / stop sun gear and flexible transmission planet gears, improving rotational stability by absorbing main shaft vibration energy, and allowing direct connection to a drive motor.

[0004] However, although the reducer improves rotational stability in actual use, it still uses a single transmission ratio for transmission output. As a result, the existing reducer still cannot achieve two transmission ratios for transmission output, which creates certain limitations in terms of application requirements. Therefore, a planetary transmission reducer based on equal strength multi-point meshing is proposed. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a planetary transmission reducer based on equal strength multi-point meshing to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a planetary transmission reducer based on equal strength multi-point meshing, comprising a housing, an end cover, an input shaft, and an output shaft. An end cover is installed at one end of the housing, and the input shaft is installed inside the end cover. The output shaft is installed at the other end of the housing. A shaft disc is installed at one end inside the housing. A connecting disc is bolted to one side of the shaft disc, and a first reduction stage is connected to one side of the connecting disc. A first sun gear is meshed with the middle of the first reduction stage, and the first sun gear is rigidly connected to the input shaft. A mating assembly is fitted to one side of the first reduction stage, and an adjustment assembly is installed on the mating assembly. A second reduction stage is fitted to one side of the mating assembly, and a transmission assembly is fitted between the second reduction stage and the mating assembly. The second reduction stage is connected to the output shaft.

[0007] Power is transmitted through the input shaft 3, causing the first sun gear 6 to rotate, thereby engaging multiple first planetary gears 903 and the first gear ring 901 to rotate, which in turn drives the connecting rods 902 to rotate synchronously. This causes the inner ring of the synchronous shaft disc 7, which is used for supporting and stabilizing the connecting disc 8, to rotate. During the rotation of the connecting rods 902, the sleeve 1002 is engaged, which in turn drives the mating disc 1001 to rotate at a reduced speed, achieving a first-stage deceleration. During the rotation of the mating disc 1001, the insert rods 1004 installed on one side rotate, which in turn drives the connecting cylinders 1203 to rotate, thereby causing the transmission disc 1202 at the other end to rotate, which in turn causes the output shaft 4 to rotate, achieving a decelerated rotation of the output shaft at the output end.

[0008] When a lower output speed is required for further deceleration, rotating the knob rotates the screw, causing the slide plate, guided by the pull rod, to move closer to the bearing seat. This causes the rollers to push the sliding grooves on the mating disc, moving the mating disc towards the first reduction stage. This allows each insert rod to be pulled out from its respective connecting cylinder, separating the insert rod from the connecting cylinder. Simultaneously, the toothed groove engages with the mating gear during movement. Two locking nuts fix the position of the slide plate. When the input shaft drives again, after the first-stage reduction rotation at the mating disc, the mating disc then rotates synchronously with the gear. This causes one end of the transmission rod to rotate within the connecting groove, driving the second sun gear to rotate. During the rotation of the second sun gear, it meshes with the second planetary gears, causing them to rotate. With the engagement of the second gear ring, the rotation of the second planetary gears drives the rotation of each connecting cylinder, causing the transmission disc connected to all the connecting cylinders to rotate, achieving a second-stage reduction. The output shaft then rotates after the second-stage reduction for output.

[0009] Preferably, the first reduction stage includes a first gear ring, which is integrally formed with the housing.

[0010] Multiple connecting rods, one end of each connecting rod is connected to the connecting plate and they are arranged in a ring. The other end of each connecting rod is inserted into the mating component.

[0015] Multiple insert rods, one end of each insert rod is welded to the other side of the mating plate, and they are arranged in a ring and inserted into one side of the second reduction stage.

[0017] Preferably, the transmission assembly includes a transmission rod, one end of which is rotatably connected to the second reduction stage.

[0018] The mating gear is installed at one end of the transmission rod and is engaged with the tooth groove.

[0019] The second sun gear is coaxially mounted on one side of the mating gear and is engaged with the second reduction stage.

[0020] Preferably, the second reduction stage includes a second gear ring, which is integrally formed with the housing.

[0021] The transmission disc is located on one side of the second gear ring, and one side of the transmission disc is coaxially connected to the output shaft. A connecting groove is provided on the other side of the transmission disc, and the connecting groove is rotatably connected to one end of the transmission rod.

[0022] Multiple connecting cylinders, one end of each connecting cylinder is connected to the transmission disc, and the other end is respectively sleeved with the corresponding insertion rod.

[0023] Multiple second planetary gears are rotatably sleeved on their respective connecting cylinders, and each second planetary gear is meshed with a second gear ring on one side and with a second sun gear on the other side.

[0024] Preferably, the outer casing has a through hole, and one end of the adjustment component passes through the through hole and is connected and engaged with the mating component.

[0025] Preferably, the adjustment assembly includes a bearing seat mounted on the housing.

[0026] The screw has one end rotatably connected to the bearing seat.

[0027] The knob is mounted on the other end of the screw.

[0028] The slide plate has one end fitted onto the screw rod.

[0029] Two locking nuts are fitted onto the screw rod and are located on opposite sides of the slide plate.

[0030] The pull rod has one end connected to the other end of the slide plate, and the other end of the pull rod passes through a through hole and is inserted into the housing.

[0031] The roller is coaxially mounted on the pull rod and is engaged in the slide groove.

[0032] Preferably, the connecting plate has a bolt hole, and the inner ring of the shaft plate has an insertion hole. The insertion hole and the bolt hole are aligned and fitted to form a fixing hole, and a bolt is installed in the fixing hole.

Furthermore, it is convenient to adjust, simple to operate, and highly stable, enabling two-stage reduction adjustment. This allows for manual adjustment according to the output speed requirements, thereby improving the applicability of the reducer and reducing its limitations.

[0038] 3. By configuring the mating disc, first sleeve, tooth groove, mating gear, transmission rod, second sun gear, second planetary gear, connecting cylinder, connecting disc, and output shaft, compared with the existing technology, when the mating disc rotates after the first reduction stage, it can drive the second sun gear to rotate, thereby achieving a second reduction with the cooperation of the second planetary gear, thus improving the minimum reduction range.

[0051] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0052] As attached Figure 1-11The illustrated planetary gear reducer based on equal-strength multi-point meshing includes a housing 1, an end cover 2, an input shaft 3, and an output shaft 4. The end cover 2 is mounted on one end of the housing 1, and the input shaft 3 is installed inside the end cover 2. The output shaft 4 is mounted on the other end of the housing 1. A shaft disc 7 is mounted inside the housing 1 at one end. A connecting disc 8 is bolted to one side of the shaft disc 7, and a first reduction stage 9 is connected to one side of the connecting disc 8. A first sun gear 6 is meshed and connected to the middle of the first reduction stage 9. The first sun gear 6 is rigidly connected to the input shaft 3. A mating assembly 10 is fitted to one side of the first reduction stage 9, and an adjusting assembly 5 is mounted on the mating assembly 10. A second reduction stage 12 is fitted to one side of the mating assembly 10, and a transmission assembly 11 is fitted between the second reduction stage 12 and the mating assembly 10. The second reduction stage 12 is connected to the output shaft 4. A through hole is provided on the outer casing 1, and one end of the adjustment assembly 5 passes through the through hole and connects with the mating assembly 10. A bolt hole is provided on the connecting disc 8, and an insertion hole is provided on the inner ring of the shaft disc 7. The insertion hole and the bolt hole are aligned to form a fixing hole, in which a bolt is installed. Power is transmitted through the input shaft 3, causing the first sun gear 6 to rotate, thereby meshing multiple first planetary gears 903 with the first gear ring 901 to rotate. This drives each connecting rod 902 to rotate synchronously, causing the inner ring of the shaft disc 7, which supports the connection disc 8, to rotate synchronously. During the rotation of each connecting rod 902, the first sleeve 1002, which is fitted, rotates at a reduced speed along with the mating disc 1001, achieving the first stage... During the deceleration process, as the mating disc 1001 rotates, the various insert rods 1004 mounted on one side rotate accordingly. This causes the insert rods 1004 to drive the connecting cylinders 1203 to rotate, which in turn causes the transmission disc 1202 at the other end to rotate, thereby causing the output shaft 4 to rotate. This achieves deceleration of the output shaft 4 at the output end. When a lower output speed is required for further deceleration, the knob 503 is turned, causing the screw 502 to rotate. This causes the slide plate 504, guided by the pull rod 506, to move closer to the position of the bearing seat 501. This causes the roller 507 to push the sliding groove 1005 provided on the mating disc 1001, causing the mating disc 1001 to move towards the position of the first deceleration stage 9. The movement causes each insert rod 1004 to be pulled out from each connecting cylinder 1203, separating the insert rod 1004 from the connecting cylinder 1203. Simultaneously, the toothed groove 1003 engages with the mating gear 1102 during the movement. Two locking nuts 505 fix the position of the slide plate 504. Thus, when the input shaft 3 resumes transmission, after a first-stage reduction rotation at the mating disc 1001, the mating disc 1001 synchronously rotates with the mating gear 1102. This causes one end of the transmission rod 1101 to rotate within the connecting groove 13, simultaneously driving the second sun gear 1103 to rotate. During the rotation of the second sun gear 1103, it meshes with each of the second planetary gears 1204, which rotate under the engagement of the second gear ring 1201.As each of the second planetary gears 1204 rotates, it drives each connecting cylinder 1203 to rotate, thereby causing the transmission disc 1202, which is connected to all the connecting cylinders 1203, to rotate. This achieves two-stage speed reduction, allowing the output shaft 4 to rotate and output power after the two-stage speed reduction.

[0053] As attached Figure 3 and Figure 4 As shown, the first reduction stage 9 includes a first gear ring 901, which is integrally formed with the outer shell 1.

[0054] Multiple connecting rods 902, one end of each connecting rod 902 is connected to the connecting plate 8 and arranged in a ring, and the other end of each connecting rod 902 is inserted into the mating component 10.

[0055] Multiple first planetary gears 903 are rotatably sleeved on corresponding connecting rods 902, and each first planetary gear 903 is meshed with a first gear ring 901 on one side and with a first sun gear 6 on the other side.

[0056] When the input shaft 3 drives the first sun gear 6 to rotate, each of the first planetary gears 903 can rotate in conjunction with the first gear ring 901, thereby causing each connecting rod 902 to rotate in a circular motion.

[0057] As attached Figure 5 and Figure 6 As shown, the mating component 10 includes a mating disk 1001, which is disposed on one side of the first reduction stage 9.

[0058] Multiple first sleeves 1002, one end of each first sleeve 1002 is welded to the mating plate 1001 and arranged in a ring, and each first sleeve 1002 is sleeved and mated with the corresponding connecting rod 902.

[0059] The toothed groove 1003 is coaxially formed in the middle of the mating plate 1001, and the toothed groove 1003 is inserted and mated with one end of the transmission component 11.

[0060] Multiple insert rods 1004 are provided, with one end of each insert rod 1004 welded to the other side of the mating plate 1001 and arranged in a ring, and inserted into one side of the second reduction stage 12.

[0061] The slide groove 1005 is located on one side edge of the mating plate 1001 and has a ring structure. One end of the adjusting component 5 is rotatably installed in the slide groove 1005.

[0062] During the circular rotation of each connecting rod 902, each first sleeve 1002 rotates synchronously, thereby causing the mating disc 1001 to rotate. When the insert rod 1004 on one side of the mating disc 1001 is inserted into the connecting sleeve 1203, it can directly drive the transmission disc 1202 to rotate, so that the output shaft 4 directly outputs the rotation speed. When the tooth groove 1003 is sleeved with the mating gear 1102, the second sun gear 1103 rotates synchronously during the rotation of the mating disc 1001. The opening of the slide groove 1005 is used to limit the roller 507, so that the roller 507 is in the slide groove 1005. During the rotation of the mating disc 1001, the roller 507 can only rotate, but its position remains unchanged.

[0063] As attached Figure 2 , Figure 8 , Figure 9 and Figure 11 As shown, the transmission assembly 11 includes a transmission rod 1101, one end of which is rotatably connected to the second reduction stage 12.

[0064] The gear 1102 is installed at one end of the transmission rod 1101 and is inserted into the tooth groove 1003.

[0065] The second sun gear 1103 is coaxially mounted on one side of the mating gear 1102, and the second sun gear 1103 is in transmission engagement with the second reduction stage 12.

[0066] When the gear 1102 is inserted into the tooth groove 1003, the synchronous mating disc 1001 can rotate synchronously, thereby causing one end of the transmission rod 1101 to rotate in the connecting groove 13 and drive the second sun gear 1103 to rotate synchronously, so that the second reduction stage 12 runs and performs secondary reduction.

[0067] As attached Figure 8 , Figure 9 and Figure 10 As shown, the second reduction stage 12 includes a second gear ring 1201, which is integrally formed with the outer shell 1.

[0068] The transmission disc 1202 is located on one side of the second gear ring 1201, and one side of the transmission disc 1202 is coaxially connected to the output shaft 4. A connecting groove 13 is provided on the other side of the transmission disc 1202, and the connecting groove 13 is rotatably connected to one end of the transmission rod 1101.

[0069] Multiple connecting cylinders 1203, one end of each connecting cylinder 1203 is connected to the transmission disc 1202, and the other end is respectively sleeved with the corresponding insertion rod 1004.

[0070] Multiple second planetary gears 1204 are rotatably sleeved on the corresponding connecting cylinders 1203, and each second planetary gear 1204 is meshed with the second gear ring 1201 on one side and with the second sun gear 1103 on the other side.

[0071] When the second sun gear 1103 meshes with each of the second planetary gears 1204 and rotates, each connecting cylinder 1203 is separated from the corresponding insert rod 1004. As a result, under the meshing and rotation of the second gear ring 1201 and the second planetary gear 1204, each connecting cylinder 1203 rotates, thereby driving the transmission disk 1202 to rotate, realizing two-stage speed reduction, and outputting the speed from the output shaft 4.

[0072] As attached Figure 2 , Figure 6 and Figure 7 As shown, the adjustment assembly 5 includes a bearing 501, which is mounted on the housing 1.

[0073] Screw 502, one end of screw 502 is rotatably connected to bearing 501.

[0074] Knob 503 is mounted on the other end of screw 502.

[0075] Slide plate 504, one end of slide plate 504 is fitted onto screw 502.

[0076] Two locking nuts 505 are fitted onto the screw 502 and are located on both sides of the slide plate 504.

[0077] Pull rod 506, one end of pull rod 506 is connected to the other end of slide plate 504, and the other end of pull rod 506 passes through the through hole and is inserted into the housing 1.

[0078] Roller 507 is coaxially mounted on pull rod 506 and is engaged in slide groove 1005.

[0079] When adjusting the minimum output speed level of the reducer, the screw 502 is rotated by manually turning the knob 503. This allows the slide plate 504 to move on the screw 502 under the guidance of the pull rod 506 inserted in the through hole. The pull rod 506 can push and pull the roller 507, thereby adjusting the position of the mating disc 1001. This changes the fit between the tooth groove 1003 and the insert rod 1004, thus achieving the speed adjustment. After the speed adjustment, the slide plate 504 is clamped and fixed by two locking nuts 505.

[0080] As attached Figure 2As shown, a retaining groove is provided at one end of the outer casing 1, and the shaft disk 7 is pressed into the retaining groove. The diameter of the shaft disk 7 is larger than the diameter of the circular surface formed by each of the first planetary gears 903. The inner diameter of the slide groove 1005 is larger than the diameter of the outer casing 1 where the second gear ring 1201 is connected, so as to avoid interference during assembly.

[0081] Working principle of this invention: When the multi-point meshing planetary transmission reducer of this strength is in use, the input shaft 3 transmits power, causing the first sun gear 6 to rotate, thereby meshing multiple first planetary gears 903 and the first gear ring 901 to rotate, thereby driving each connecting rod 902 to rotate synchronously, so that the inner ring of the synchronous shaft disc 7 used for supporting and stabilizing the connecting disc 8 rotates. During the rotation of each connecting rod 902, the sleeve 1002 is driven by the mating disc 1001 to rotate at a reduced speed, achieving a first-stage reduction. During the rotation of the mating disc 1001, each insert rod 1004 installed on one side rotates, thereby driving each connecting cylinder 1203 to rotate, thereby causing the transmission disc 1202 at the other end to rotate, thereby causing the output shaft 4 to rotate, achieving a reduced-speed rotation of the output shaft 4 at the output end;

[0082] When a lower output speed is required for further deceleration, rotating the knob 503 causes the screw 502 to rotate, which in turn causes the slide plate 504, guided by the pull rod 506, to move closer to the bearing seat 501. This causes the roller 507 to push the sliding groove 1005 on the mating disc 1001, moving the mating disc 1001 towards the first reduction stage 9. This causes each insert rod 1004 to be pulled out from each connecting cylinder 1203, separating the insert rod 1004 from the connecting cylinder 1203. Simultaneously, the toothed groove 1003 engages with the mating gear 1102 during movement. The position of the slide plate 504 is fixed by two locking nuts 505, thus allowing the input shaft 3 to transmit power again. During operation, after the first-stage reduction rotation is achieved at the mating disc 1001, the mating disc 1001 then synchronously rotates with the gear 1102. This causes one end of the transmission rod 1101 to rotate within the connecting groove 13, simultaneously driving the second sun gear 1103 to rotate. As the second sun gear 1103 rotates, it meshes with each of the second planetary gears 1204, causing them to rotate. With the cooperation of the second gear ring 1201, the rotation of each of the second planetary gears 1204 drives each of the connecting cylinders 1203 to rotate, thereby causing the transmission disc 1202, which is connected to all the connecting cylinders 1203, to rotate, achieving a second-stage reduction. This allows the output shaft 4 to rotate and output power after the second-stage reduction.

[0083] The present invention has the advantage of being able to adjust the transmission speed of the output shaft 4, thereby achieving two-stage speed regulation, and adjusting the required transmission speed according to different situations, thereby improving the planetary transmission reducer to meet greater needs and expanding the applicability of the reducer.
