The swing ring box is an important component on the header of the harvester. Its main function is to drive the linear motion of the power shaft to drive the cutter assembly to achieve the function of cutting crops.

[0003] The current mainstream swing ring box is the swing arm type swing ring box, which is driven by a belt pulley. It has the disadvantages of large vibration amplitude, single speed, and short life. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the existing pendulum ring box uses a belt drive, which results in large vibration amplitude and single rotation speed. In order to solve this technical problem, this utility model provides a motor-driven speed-increasing planetary pendulum ring box and a harvester header.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: This utility model provides a motor direct-drive speed-increasing planetary ring gearbox, including a housing, a hydraulic motor, a flywheel, a driving bevel gear, a driven bevel gear, a planetary carrier, a gear ring, an output planetary gear shaft, and an output derailleur. The power shaft of the hydraulic motor is coaxially connected to the driving bevel gear through the flywheel. The driving bevel gear and the driven bevel gear are rotatably mounted in the housing and mesh with each other. The central axis of the driven bevel gear is perpendicular to the central axis of the driving bevel gear. One end of the planetary carrier is coaxially mounted with the driven bevel gear, and the middle part of the planetary carrier is rotatably connected to the housing. A gear ring is also fixed in the housing. The gear ring is coaxially arranged with the driven bevel gear and spaced outside the planetary carrier. An output planetary gear shaft is eccentrically rotatably connected to the planetary carrier. The output planetary gear shaft has a ring of meshing teeth that mesh with the gear ring. An output derailleur is eccentrically connected to one end of the output planetary gear shaft that extends out of the planetary carrier.

[0006] The beneficial effects of this utility model are as follows: The motor-driven planetary pendulum ring box of this utility model is driven by a hydraulic motor and has its own flywheel structure. It has high reliability, strong stability and compact structure. The hydraulic motor drive is relatively stable and reduces the vibration amplitude. At the same time, the hydraulic motor can provide different speeds, realizing the adjustable cutting speed of crops, enabling the harvesting of different crops and crops with different degrees of dryness and moisture. In addition, the flywheel structure increases the rotational inertia, making the operation of the cutter assembly more stable.

[0007] The present invention relates to a motor-driven direct-drive planetary pendulum ring box, which uses a hydraulic motor to input power and drive a flywheel to rotate. The flywheel is redirected by a pair of bevel gears and then achieves the linear motion of the final output shaft through two eccentric structures.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, the main structure of the hydraulic motor is fixedly connected to the housing via a motor support base, which is an L-shaped casting.

[0010] The beneficial effects of adopting the above-mentioned further solution are: the motor support base adopts an L-shaped structure casting, and the contact position is machined to meet the high precision requirements of the parts and ensure that the hydraulic motor power shaft and flywheel are coaxial.

[0011] Furthermore, a mounting plate is fixed on the outer wall of the housing. The mounting plate is arranged near the gear ring and located on one side of the flywheel. The mounting plate is arranged parallel to the central axis of the driving bevel gear. One end of the L-shaped casting is fixed to the side of the main structure of the hydraulic motor near the flywheel, and the other end is fixed to the mounting plate.

[0012] The beneficial effect of adopting the above-mentioned further solution is that by fixing the mounting plate on the outer side wall of the housing, the installation and fixation of the motor support base is more stable and reliable.

[0013] Furthermore, the power shaft of the hydraulic motor is coaxially and fixedly connected to the flywheel. A flange is bolted to the side of the flywheel away from the hydraulic motor. The flange has a hollow structure. The active bevel gear is coaxially and limitedly inserted into the hollow structure of the flange. The flange is rotatably connected to the inner wall of the housing through a first bearing.

[0014] The beneficial effect of adopting the above-mentioned further solution is that by setting a flange, it is convenient to stably assemble the flywheel and the driving bevel gear.

[0015] Furthermore, the driving bevel gear has a hollow structure, and a support shaft is fitted inside the hollow structure of the driving bevel gear. One end of the support shaft is rotatably connected to the inner wall of the housing through a second bearing, and the other end of the support shaft is limited to the side of the flange near the flywheel by a first limiting ring and a first locking nut; the second bearing is a double-row angular contact ball bearing.

[0016] The beneficial effect of adopting the above-mentioned further solution is that by setting a support shaft, it is convenient to stably assemble the driving bevel gear.

[0017] Furthermore, the driven bevel gear has a hollow structure, one end of the planetary carrier is inserted into the hollow structure of the driven bevel gear and is limited to the driven bevel gear by a spline, and one end face of the planetary carrier is locked and positioned with the driven bevel gear by a second limiting ring and a locking bolt.

[0018] The beneficial effect of adopting the above-mentioned further solution is that the driven bevel gear adopts a hollow structure, which facilitates the stable assembly of the driven bevel gear and the planetary carrier.

[0019] Furthermore, the passive bevel gear is rotatably connected to the inner wall of the housing via a third bearing, and the planetary carrier is rotatably connected to the inner wall of the housing via a fourth bearing. One end of the output planetary gear shaft that extends into the planetary carrier is rotatably connected to the planetary carrier via a fifth bearing, and the other end of the output planetary gear shaft that is close to the outside of the planetary carrier is rotatably connected to the planetary carrier via a sixth bearing; the fifth bearing is a needle roller bearing, and the sixth bearing is a double-row angular contact ball bearing.

[0020] Furthermore, a bushing is rotatably connected to the output dial shaft via a seventh bearing. The end face of the output dial shaft facing away from the output planetary gear shaft is pressed and limited by a third limiting ring and a hollow bolt. The bushing is sleeved outside the seventh bearing and fixedly connected to the outer ring of the seventh bearing. The bushing has a space that connects the seventh bearing with the hollow structure of the hollow bolt. An oil passage communicating with the outside is provided on the output dial shaft, and the oil passage communicates with the hollow structure of the hollow bolt.

[0021] The beneficial effect of adopting the above-mentioned further solution is that, by using hollow bolts, grease can be connected to the hollow bolts through oil passages and eventually enter the seventh bearing to achieve lubrication of the seventh bearing.

[0022] Furthermore, the number of teeth of the active bevel gear is greater than the number of teeth of the passive bevel gear; the housing is provided with a screw plug and a vent plug.

[0023] This utility model also provides a harvester header, including the motor direct-drive speed-increasing planetary swing ring box as described above.

[0027] The principles and features of this utility model are described below. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0028] Example 1 like Figures 1-4As shown, this embodiment of a motor-driven direct-drive speed-increasing planetary gearbox includes a housing 1, a hydraulic motor 2, a flywheel 3, a driving bevel gear 4, a driven bevel gear 41, a planet carrier 5, a gear ring 51, an output planetary gear shaft 52, and an output shift shaft 53. The power shaft 21 of the hydraulic motor 2 is coaxially connected to the driving bevel gear 4 via the flywheel 3. Both the driving bevel gear 4 and the driven bevel gear 41 are rotatably mounted inside the housing 1 and mesh with each other. The central axis of the driven bevel gear 41 is parallel to the central axis of the driving bevel gear 4. Vertical; one end of the planetary carrier 5 is coaxially mounted with the driven bevel gear 41, the middle part of the planetary carrier 5 is rotatably connected to the housing 1, and a gear ring 51 is fixed inside the housing 1. The gear ring 51 is coaxially arranged with the driven bevel gear 41 and spaced out from the planetary carrier 5. An output planetary gear shaft 52 is eccentrically rotatably connected to the planetary carrier 5. The output planetary gear shaft 52 is provided with a ring of meshing teeth that mesh with the gear ring 51. An output deflector shaft 53 is eccentrically connected to one end of the output planetary gear shaft 52 that extends out of the planetary carrier 5.

[0029] like Figure 1 and Figure 2 As shown, the number of teeth of the driving bevel gear 4 is greater than the number of teeth of the driven bevel gear 41; the housing 1 is provided with a screw plug 190 and a vent plug 191. The screw plug 190 is arranged close to the support shaft 42, and the vent plug 191 is arranged adjacent to the screw plug 190. The screw plug 190 facilitates the addition of grease and also facilitates the observation of the meshing of the driving and driven bevel gears during gearbox assembly.

[0030] Among them, such as Figure 4 As shown, in this embodiment, a portion of the output planetary gear shaft 52 protrudes from the center of the planet carrier 5 and is used to mesh with the gear ring 51. In this embodiment, the gear ring 51 and the fourth bearing 16 are arranged coaxially adjacent to each other.

[0031] In this embodiment, the power transmission route of the motor-driven direct-drive planetary ring gearbox is as follows: the hydraulic motor 2 provides power to drive the flywheel 3 via the transmission shaft 21. The flywheel 3 drives the flange 32, which in turn drives the driving bevel gear 4. The driving bevel gear 4 meshes with and drives the driven bevel gear 41. The driven bevel gear 41 drives the planet carrier via a spline engagement. The output planetary gear shaft 52 meshes with the gear ring 51 at an eccentric position on the planet carrier 5, causing it to rotate. The output shift shaft 53 rotates at an eccentric position on the output planetary gear shaft 52. The combined eccentric rotation of the two shafts ultimately achieves linear motion of the output shift shaft. Linear motion of the output shift shaft can be achieved through proper assembly. This assembly method and linear motion of the output shift shaft can be implemented using conventional assembly methods and structures of planetary ring gearboxes.

[0032] The direct-drive speed-increasing planetary pendulum ring box of this embodiment is driven by a hydraulic motor and has its own flywheel structure. It has high reliability, strong stability and compact structure. The hydraulic motor drive is more stable and reduces the vibration amplitude. At the same time, the hydraulic motor can provide different speeds, realizing the adjustable cutting speed of crops, enabling the harvesting of different crops and crops with different dryness and moisture levels. In addition, the flywheel structure increases the rotational inertia, making the cutter assembly operate more smoothly.

[0033] In this embodiment, the motor-driven speed-increasing planetary pendulum ring box is powered by a hydraulic motor, which drives the flywheel to rotate. The flywheel is redirected by a pair of bevel gears and then achieves the linear motion of the final output shaft through two eccentric structures.

[0034] Example 2 Based on Example 1, this example provides a stable support scheme for the hydraulic motor 2. For example... Figure 2 As shown, the main structure of the hydraulic motor 2 is fixedly connected to the housing 1 via a motor support base 12, which is an L-shaped casting. The motor support base is an L-shaped casting, and the contact position is machined to meet the high precision requirements of the components, ensuring that the hydraulic motor's power shaft is coaxial with the flywheel.

[0035] like Figure 2 As shown, preferably, a mounting plate 11 is fixed to the outer wall of the housing 1. The mounting plate 11 is arranged near the gear ring 51 and located on one side of the flywheel 3. The mounting plate 11 is arranged parallel to the central axis of the driving bevel gear 4. One end of the L-shaped casting is fixed to the side of the main structure of the hydraulic motor 2 near the flywheel 3, and the other end is fixed to the mounting plate 11. By fixing the mounting plate to the outer wall of the housing, the installation and fixation of the motor support is more stable and reliable.

[0036] In this embodiment, the motor support 12 is a casting, which ensures assembly accuracy.

[0037] Example 3 Based on Embodiment 1 or Embodiment 2, this embodiment provides a stable assembly scheme for the flywheel 3 and the driving bevel gear 4. For example... Figure 2 As shown, the power shaft 21 of the hydraulic motor 2 is coaxially and fixedly connected to the flywheel 3. A flange 32 is bolted to the side of the flywheel 3 facing away from the hydraulic motor 2. The flange 32 is a hollow structure. The driving bevel gear 4 is coaxially and limitedly inserted into the hollow structure of the flange 32. The flange 32 is rotatably connected to the inner wall of the housing 1 via a first bearing 13. The flange facilitates stable assembly between the flywheel and the driving bevel gear. Specifically, as... Figure 2As shown, in this embodiment, the power shaft 21 of the hydraulic motor 2 passes through the hollow structure of the flywheel 3 and is limited to the flywheel 3 by a first flat key 33. The support shaft 42 passes through the hollow structure of the flange 32 and is limited to the flange 32 by a second flat key 34.

[0038] like Figure 2 As shown, the driving bevel gear 4 has a hollow structure, and a support shaft 42 is fitted inside the hollow structure. One end of the support shaft 42 is rotatably connected to the inner wall of the housing 1 through a second bearing 14, and the other end of the support shaft 42 is limited to the side of the flange 32 near the flywheel 3 by a first limiting ring 43 and a first locking nut 44. The second bearing 14 is a double-row angular contact ball bearing. By setting the support shaft, the stable assembly of the driving bevel gear is facilitated.

[0039] Specifically, such as Figure 2 As shown, in this embodiment, one end of the support shaft 42 is limited to one end of the inner ring of the second bearing 14 by a fourth limiting retaining ring 491. A second locking nut 490 is also screwed onto one end of the support shaft 42, which is used to limit and lock the fourth limiting retaining ring 491. Both ends of the support shaft 42 are tightened by limiting retaining rings, and the support shaft 42 is also provided with an annular limiting step, on which the gear end of the driving bevel gear 4 can abut against the annular limiting step. The gear shaft end of the driving bevel gear 4 is tightened and limited by the first limiting retaining ring 43 and the first locking nut 44. The overall structure is stable and compact.

[0040] Example 4 Based on any of the above embodiments, this embodiment provides a stable assembly scheme for the passive bevel gear 41 and the planetary carrier 5. For example... Figure 3 and Figure 4 As shown, the driven bevel gear 41 has a hollow structure. One end of the planetary carrier 5 is inserted into the hollow structure of the driven bevel gear 41 and is engaged with the driven bevel gear 41 by a spline 45. One end face of the planetary carrier 5 is locked and positioned with the driven bevel gear 41 by a second limiting retaining ring 46 and a locking bolt 47. The hollow structure of the driven bevel gear facilitates stable assembly between the driven bevel gear and the planetary carrier.

[0041] like Figure 2 As shown, the driven bevel gear 41 is rotatably connected to the inner wall of the housing 1 via the third bearing 15, and the planetary carrier 5 is rotatably connected to the inner wall of the housing 1 via the fourth bearing 16; Figure 4As shown, one end of the output planetary gear shaft 52 extending into the planetary carrier 5 is rotatably connected to the planetary carrier 5 via a fifth bearing 17, and the other end of the output planetary gear shaft 52 near the outside of the planetary carrier 5 is rotatably connected to the planetary carrier 5 via a sixth bearing 18; the fifth bearing 17 is a needle roller bearing, and the sixth bearing 18 is a double-row angular contact ball bearing.

[0042] like Figure 4 As shown, a bushing 54 is rotatably connected to the output shaft 53 via a seventh bearing 19. The end face of the output shaft 53 facing away from the output planetary gear shaft 52 is press-fitted and limited by a third limiting ring 48 and a hollow bolt 49 to the inner ring of the seventh bearing 19. The bushing 54 is fitted over the seventh bearing 19 and fixedly connected to its outer ring. The bushing 54 has a space connecting the seventh bearing 19 to the hollow structure of the hollow bolt 49. An oil passage 56 communicating with the outside is provided on the output shaft 53, and this oil passage 56 communicates with the hollow structure of the hollow bolt 49. Using a hollow bolt, grease can communicate through the oil passage and the hollow bolt, ultimately entering the seventh bearing to achieve lubrication.

[0043] Specifically, such as Figure 4 The side wall outlet of the oil passage 56 can be sealed by an oil plug 57. The bushing 54 can be sealed and rotated with the output shaft 53 by an oil seal 55.

[0044] In this embodiment, the eccentric assembly and linear motion of the output dial 53 can be achieved using existing common assembly structures.

[0045] Example 5 This embodiment also provides a harvester header, including a motor-driven speed-increasing planetary pendulum ring box as described above.

[0046] The harvester header in this embodiment, through a new layout and structure design, enables the gearbox to be driven by a hydraulic motor, which in turn drives the cutter assembly to cut crops. This greatly reduces the failure rate and maintenance cost of the header transmission module, improves transmission efficiency, and allows the hydraulic motor to provide different speeds to harvest crops with different moisture levels in different areas.
