Description
Technical Field
[0001] The utility model relates to the technical field of sprockets, in particular to a sprocket mechanism for improving load and facilitating disassembly and adjustment. Background Technique
[0002] The round bale baler is a forage machine driven by a tractor hitch. It mainly drives the side drum sprocket through a chain, so that all drums rotate clockwise synchronously, compresses the internal forage into a mold and then forms a bale with a net.
[0003] In the prior art, a taper bushing structure is often used to install and disassemble the sprocket, which still has the following disadvantages: the installation and adjustment of the taper bushing structure are relatively convenient, but it is easy to slip after using an overload torque, which may cause damage to the mating friction surface and damage to parts. Content of the Utility Model
[0004] The purpose of the utility model is to provide a sprocket mechanism for improving load and facilitating disassembly and adjustment, so as to solve the problem that it is easy to slip after using an overload torque, which may cause damage to the mating friction surface and damage to parts.
[0005] In order to achieve the above-mentioned utility model purpose, the utility model adopts the following technical solutions: a sprocket mechanism for improving load and facilitating disassembly and adjustment, including a drum weldment. One end of the drum weldment is provided with a shaft head, and an installation groove is opened on the surface of the shaft head. A sprocket body is slidably inserted into the installation groove. A limiting groove is opened on the surface of the installation groove. A woodruff key is arranged inside the sprocket body, and the woodruff key is slidably arranged with the limiting groove. Two taper bushings are arranged inside the sprocket body, and the taper bushings are slidably arranged with the installation groove.
[0006] Preferably, a threaded groove is opened on the surface of the shaft head, and a nut is threadedly connected to the surface of the threaded groove.
[0007] Preferably, a second gasket is rotatably inserted into the surface of the threaded groove, and the second gasket is located between the nut and the sprocket body.
[0008] Preferably, a web plate is arranged at one end of the drum weldment, a side plate is fixed on one side of the web plate, and a bearing seat is arranged on one side of the side plate.
[0009] Preferably, a first gasket is slidably inserted into the shaft head, and a plurality of adjusting gaskets are slidably inserted into the shaft head.
[0010] Preferably, one end of the adjusting gasket is fixed with a splicing plate, and the other end of the adjusting gasket is provided with a splicing groove.
[0011] Compared with the prior art, a sprocket mechanism for improving load and facilitating disassembly and adjustment adopting the above technical solutions has the following beneficial effects:
[0012] 1. When installing the sprocket body on the shaft head, the sprocket body is made of grey pottery and is arranged on the surface of the installation groove. At this time, it will drive the semi-circular key to slide on the surface of the installation groove and finally embed into the internal limit groove, so that the radial force of the sprocket body can be directly transmitted to the shaft head. Then, the operator installs the tapered sleeve between the installation groove and the sprocket body, making the sprocket body fit tightly with the surface of the installation groove. The semi-circular key embedded in the limit groove increases the bearing torque of the sprocket body on the shaft head, improves the stability of the whole structure, and prevents the components from being damaged.
[0013] 2. After installing the sprocket body on the shaft head, the operator tightens the nut on the thread groove, increasing the axial force continuously. Then, the tapered sleeve can be slowly pushed into the sprocket body. After the nut is tightened to the specified torque value, the axial pressure between the inner and outer parts of the tapered sleeve and the fitted parts reaches the design value, thus increasing the firmness of the sprocket body on the shaft head.
[0014] 3. By increasing or decreasing the number of adjusting pads, the sprocket body can be adjusted to be coplanar with other sprocket bodies. When adding adjusting pads, first install one adjusting pad on the shaft head, then turn the other adjusting pad 180 degrees, and then assemble the two adjusting pads together, making the splicing plate and splicing groove of the former assemble into the splicing groove and splicing plate of the latter to form a ring, which is convenient for adding an extra number of adjusting pads.

[0020] The following will describe in detail the preferred embodiments of the present invention with reference to the drawings.
[0021] As Figures 1-3As shown in the figure, a sprocket mechanism for improving load and facilitating disassembly and adjustment includes a drum welding 1. One end of the drum welding 1 is provided with a shaft head 2. The surface of the shaft head 2 is provided with an installation groove 4. A sprocket body 3 is slidably inserted on the installation groove 4. The surface of the installation groove 4 is provided with a limiting groove 8. Inside the sprocket body 3, a woodruff key 9 is provided. The woodruff key 9 is slidably arranged with the limiting groove 8. Inside the sprocket body 3, two taper sleeves 7 are provided. The taper sleeves 7 are slidably arranged with the installation groove 4.
[0022] During use, when installing the sprocket body 3 on the shaft head 2, the sprocket body 3 is arranged on the surface of the installation groove 4. At this time, it will drive the woodruff key 9 to slide on the surface of the installation groove 4 and finally embed into the inside of the limiting groove 8, so that the radial force of the sprocket body 3 can be directly transmitted to the shaft head 2. Then the staff installs the taper sleeve 7 between the installation groove 4 and the sprocket body 3, making the sprocket body 3 closely fit with the surface of the installation groove 4. By the woodruff key 9 embedded in the limiting groove 8, the bearing torque of the sprocket body 3 on the shaft head 2 is increased, and the stability of the whole structure is increased, preventing damage to parts.
[0023] As Figure 2 and Figure 3 shown in the figure, the surface of the shaft head 2 is provided with a threaded groove 5. A nut 6 is threadedly connected to the surface of the threaded groove 5. A second gasket 16 is rotatably inserted on the surface of the threaded groove 5. The second gasket 16 is located between the nut 6 and the sprocket body 3.
[0024] During use, after installing the sprocket body 3 on the shaft head 2, the staff will tighten the nut 6 on the threaded groove 5, so that the axial force continuously increases. Then the taper sleeve 7 can be slowly pushed into the sprocket body 3. After the nut 6 is tightened to the specified torque value, the axial pressure between the inner and outer parts of the taper sleeve 7 and the fitting parts reaches the design value, thereby increasing the firmness of the sprocket body 3 on the shaft head 2.
[0025] As Figure 3 and Figure 4 shown in the figure, one end of the drum welding 1 is provided with a web plate 17. One side of the web plate 17 is fixed with a side plate 10. One side of the side plate 10 is provided with a bearing seat 11. A first gasket 12 is slidably inserted on the shaft head 2. A plurality of adjusting gaskets 13 are slidably inserted on the shaft head 2. One end of the adjusting gasket 13 is fixed with a splicing plate 14. The other end of the adjusting gasket 13 is provided with a splicing groove 15.
[0026] In use, the sprocket body 3 can be adjusted to be coplanar with other sprocket bodies 3 by increasing or decreasing the number of adjustment pads 13. When adding adjustment pads 13, one adjustment pad 13 is first installed on the shaft head 2, and then the other adjustment pad 13 is flipped 180 degrees. Then, the two adjustment pads 13 are assembled together so that the splicing plate 14 and splicing groove 15 of the former are assembled in the splicing groove 15 and splicing plate 14 of the latter to form a ring, facilitating the addition of an extra number of adjustment pads 13.
[0027] The above is only the preferred specific implementation mode of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and inventive concept of the present utility model, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
