[0026] The present invention is further described in detail below in conjunction with the embodiments. It should be understood that the directions or positional relationships indicated by the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside" and "outside" herein are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0027] This embodiment provides a transmission device for farming, such as Figure 1 and Figure 2 As shown, it includes a box body component, an input shaft component, a transmission shaft component, and an output shaft component. The box body component includes a main box body 1 and a box cover 2 fixed by bolts. At the same time, three independent holes are provided in the main box body 1 for installing the input shaft component, the transmission shaft component, and the output shaft component respectively. The setting of the independent holes can improve the convenience of disassembly and assembly.

[0028] The input shaft components include an input shaft 3, an input gear 8, a ball bearing, two tapered bearings, a spacer 1 5, a spacer 2 7, an input bearing pressure plate 6 and an input shaft end cover 4. Figure 2The input shaft 3 is horizontally arranged, and its right end is supported on the main housing 1 by a tapered bearing, and is sealed by an input shaft end cover 4, and a groove is formed on the input shaft end cover 4 and an O-ring is installed. The middle part of the input shaft 3 is supported on the main housing 1 by a tapered bearing, and the tapered bearing is limited by a spacer 1 5 and a spacer 2 7, and is fixed by an input bearing pressure plate 6, which is installed on the side facing the housing cover 2. The input bearing pressure plate 6 is installed on the side facing the housing cover 2, which is conducive to the disassembly of the input bearing pressure plate 6, thereby facilitating the disassembly of the input shaft 3. The right end of the input shaft 3 is supported on the housing cover 2 by a ball bearing. When installing, the housing cover 2 is tightened, so that the ball bearing can press the input shaft 3, thereby achieving the stability of the input shaft component. The input gear 8 is connected to the left end of the input shaft 3 by a key. Since the input gear 8 is located on one side of the housing cover 2, the input gear 8 can be taken out after the housing cover 2 is removed.

[0029] The transmission shaft components include a transmission shaft 10, a transmission gear 9, a transmission bevel gear 12, a ball bearing, two tapered bearings, a spacer 7, a transmission bearing pressure plate 11 and a transmission shaft end cover 17. Figure 2 The transmission shaft 10 is horizontally arranged, that is, parallel to the input shaft 3, and its right end is supported on the main housing 1 by a tapered bearing, and is sealed by a transmission shaft end cover 17, and the transmission shaft end cover 17 is grooved and installed with an O-ring. The transmission bevel gear 12 is installed in the middle of the transmission shaft 10, and the middle part is supported on the main housing 1 by a tapered bearing, and is limited by a spacer ring 7, and is fixed by a transmission bearing pressure plate 11. The transmission bearing pressure plate 11 is installed on the side facing the housing cover 2, and the transmission shaft 10 pressure plate is installed on the side facing the housing cover 2, which is conducive to the disassembly of the transmission bearing pressure plate 11, thereby facilitating the disassembly of the transmission shaft 10. The right end of the transmission shaft 10 is supported on the housing cover 2 by a ball bearing. During installation, the housing cover 2 is tightened, so that the ball bearing can press the transmission shaft 10, thereby achieving the stability of the transmission shaft components. The transmission gear 9 is connected to the left end of the transmission shaft 10 through a key. Since the transmission gear 9 is located on one side of the box cover 2, the transmission gear 9 can be taken out after the box cover 2 is removed. The input gear 8 is meshed with the transmission gear 9.

[0030] When it is necessary to adapt to different types of tractors and plowing devices, the input gear 8 and the transmission gear 9 can be removed by removing the cover 2, and the input gear 8 and the transmission gear 9 of the adapted speed ratio can be installed. The input gear 8 and the transmission gear 9 replaced here need to have a unified interface size so as to be conveniently and quickly installed on the corresponding input shaft 3 and the transmission shaft 10. At the same time, the main box 1 is reserved for the installation space for replacing different parts to meet the needs of large speed ratio and high power models.

[0031] The output shaft component includes an output shaft 15, an output bevel gear 13, an output bearing seat 14, a tapered bearing, a lip seal A, a lip seal B and an output shaft end cover 16. The output shaft 15 is arranged perpendicular to the transmission shaft 10 and is mounted on the output bearing seat 14 through a tapered bearing. The output bearing seat 14 is fixed to the main housing 1 by bolts. The output bevel gear 13 is mounted on one end of the output shaft 15 located in the main housing. The output bevel gear 13 is meshed with the transmission bevel gear 12. The end of the output shaft 15 located outside the main housing 1 is used to output power.

[0032] The power transmission path of this scheme is as follows Figure 4 As shown: power is transmitted from the input shaft 3, through the input gear 8 to the transmission gear 9, driving the output bevel gear 13 meshing with the transmission bevel gear 12 to rotate, and the output bevel gear 13 is tightly connected to the output shaft 15 to achieve power output.

[0033] Since the gearbox needs to be filled with lubricating oil to lubricate the shaft system components, the left ends of the input shaft component and the transmission shaft component have been sealed by end covers 4 and 17. This embodiment makes certain improvements to the output shaft component, as follows:

[0034] like Figure 2 As shown, the inner side of the output bearing seat 14 is tapered to a certain extent, so that when the lubricating oil is in a static state, the lubricating oil can slowly flow to the side of the box cover 2. When unpacking, there is no need to swing the transmission box or invert the transmission box to drain all the lubricating oil, thereby reducing the pollution to the environment caused by the oil outflow when unpacking. At the same time, in order to achieve the smooth flow of lubricating oil to the side of the box cover 2, as shown in FIG. Figure 3 As shown, the inner wall of the main housing 1 is grooved for guidance, so that the oil circuit on the conical side of the output bearing seat 14 is connected with the oil circuit on the side of the cover 2 (the oil circuit itself is there, but it is blocked by the ribs of the main housing 1 when it flows from the main housing 1 to the cover 2, so it needs to be grooved for guidance). At the same time, part of the lubricating oil will flow into the bearing at the input shaft 3. In order to prevent the lubricating oil from flowing out and achieve better sealing, this embodiment is also provided with an independent oil chamber 20 in the output bearing seat 14, and lip-shaped sealing rings A and lip-shaped sealing rings B are provided between the output bearing seat 14 and the main housing 1, which are located on the upper and lower sides of the independent oil chamber 20, wherein the lip-shaped sealing ring A is located between the independent oil chamber 20 and the bearing at the output shaft 15, and the lip-shaped sealing ring B is located outside the independent oil chamber 20. Finally, the output shaft end cover 16 is installed outside the lip-shaped sealing ring B for locking and sealing. The independent oil chamber 20 is provided in the output bearing seat 14, and the oil can be drained independently after removal to avoid the backflow of lubricating oil and pollution of the environment during disassembly.

[0035] The above embodiments are only used to explain the concept of the present invention, rather than to limit the protection of the rights of the present invention. Any non-substantial changes to the present invention using this concept shall fall within the protection scope of the present invention.
