In the following, the specific structure of the above-mentioned parts of the power output transmission device according to the utility model will be described in detail.

[0034] In this embodiment, if Figure 1 to Figure 2As shown, the active disk assembly includes a chassis 10, an active disk 11 and a fixed disk 12 connected in sequence. The chassis 10 and the active disk 11 are both formed into a disc-shaped structure, and the outer diameter of the active disk 11 is larger than the outer diameter of the chassis 10, so as to facilitate the stable connection of the device with other components in the harvesting machine drive part described below. The fixed disk 12 is formed into a cylindrical groove structure, that is, the axial section of the fixed disk 12 is formed into a U-shaped structure, and the outer diameter of the fixed disk 12 is also smaller than the outer diameter of the active disk 11. It should be noted that the specific specifications of the chassis 10, the active disk 11 and the fixed disk 12, such as their outer diameters and thicknesses, are not limited, as long as they meet the strength and rigidity requirements of the device when used, and are convenient for assembly between the components. In addition, the connection method of the chassis 10, the active disk 11 and the fixed disk 12 is not fixed. For example, in the embodiment, the three are connected correspondingly by multiple screws; or, the connection of the three can also be achieved by connecting parts such as buckles and pins.

[0035] Furthermore, after the chassis 10, the active disk 11 and the fixed disk 12 are connected, the axes of the three are collinear, which can improve the stability of the overall structure of the active disk assembly. In addition, the active disk assembly in this embodiment is formed with an assembly hole corresponding to the disk hub 2 at the center, that is, the chassis 10, the active disk 11 and the fixed disk 12 are all formed with sub-assembly holes corresponding to the disk hub 2, so as to improve the stability of the assembly of the disk hub 2 and the active disk assembly. Furthermore, the open space of the fixed disk 12 is formed as a mounting portion corresponding to the disk hub 2.

[0036] In this embodiment, if Figure 1 As shown, the active disk 11 is formed with a plurality of mounting and connecting holes 110, and the plurality of mounting and connecting holes 110 are evenly distributed along the circumference of the active disk 11, and the mounting and connecting holes 110 are all located at the edge of the active disk 11 away from the above-mentioned (sub) assembly hole; preferably, the plurality of mounting and connecting holes 110 are located on the same circumference of the active disk 11. The present device can be connected to the drive part of the harvesting machinery described below through the mounting and connecting holes 110. In addition, the active disk 11 is also formed with a plurality of card slots 111, and the card slots 111 are formed into an open structure of a U-shape and its opening is located at the outer edge of the active disk 11, and the plurality of card slots 111 are evenly distributed along the circumference of the active disk 11, and the card slots 111 are staggered with the mounting and connecting holes 110, and can be correspondingly engaged with the protrusions on the drive part of the harvesting machinery through the card slots 111, so as to increase the stability of the present device after connection, thereby increasing the stability of power transmission.

[0037] It should be noted that there is no specific limitation on the specifications and quantity of the above-mentioned installation connection holes 110 and the card slots 111, as long as the above-mentioned technical effects can be achieved.

[0038] In this embodiment, if Figure 2As shown, the disc hub 2 is also formed into a disc-like structure, and a protrusion 20 is formed at the center thereof, and the protrusion 20 protrudes from the two end faces in the axial direction of the disc hub 2. When the disc hub 2 is assembled with the active disc assembly, the first end of the protrusion 20 in the axial direction is matched with the above-mentioned assembly hole, so that the disc hub 2 is placed in the mounting portion as a whole, and the outer wall of the disc hub 2 is abutted against the inner wall of the fixed disc 12. Further, the active disc assembly also includes a pressure plate 13, which is sleeved on the second end of the protrusion 20 in the axial direction, so that the pressure plate 13 is located at the opening of the fixed disc 12 and the two are welded correspondingly, so that the stability and tightness of the connection between the active disc assembly and the disc hub 2 are guaranteed, thereby improving the stability of the device when transmitting power, and can effectively avoid the situation where the device emits abnormal noise when transmitting power. Furthermore, a damping gasket 40 is also arranged between the disc hub 2 and the pressure plate 13 to compensate for the axial error of the device, so as to be more conducive to the realization of the above-mentioned technical effects.

[0039] In this embodiment, if Figure 1 to Figure 2 As shown, a plurality of square holes 22 are formed at the main body of the disc hub 2, and the plurality of square holes 22 are evenly distributed along the circumference of the disc hub 2, and a spring assembly is correspondingly arranged in each square hole 22.

The above-mentioned double spring structure can achieve the technical effect of transmitting torque and shock absorption, that is, the spring assembly can absorb energy when the torque is large, and can release energy when the torque is small, thereby effectively improving the stability of the device when transmitting power. Correspondingly, the pressure plate 13 is also formed with a hollow hole 130 corresponding to the spring assembly.

[0040] In addition, the protrusion 20 of the hub 2 is formed with a connecting through hole 21 for correspondingly connecting with the drive shaft of the harvesting machine driving part to facilitate power transmission.

Compared with the existing structure, the shock absorption effect of the device of the utility model is significantly enhanced.

[0043] In addition, the device is also provided with an annular disc spring 41 and a limit seat 42 between the active disk assembly and the disk hub 2. The limit assembly can play the role of axial limitation, thereby effectively increasing the stability and tightness of the connection between the active disk assembly and the disk hub 2, thereby effectively avoiding the possibility of abnormal noise.
