Description

Technical Field

[0001] This invention relates to the field of winch manufacturing, and particularly to a lightweight double-drum winch structure. Background Technology

[0002] Traditional double-drum winches use multi-stage gear transmission via parallel shafts. To meet the demands of speed reduction and torque increase, the size and weight of the final stage gear and gearbox within the gearbox significantly increase. This results in a bulky and heavy gearbox and even the entire equipment, making it difficult to transport in the field without lifting equipment, reducing portability and affecting on-site deployment efficiency. Furthermore, the power distribution of the two drums within the gearbox relies on single-tooth transmission of three gears, with the entire power of the drive gear being borne by a single set of intermediate gears. Excessive gear load and long-term high-load operation can easily lead to tooth surface wear or even tooth breakage, shortening service life, increasing maintenance costs, and potentially causing power transmission interruption due to gear failure, thus posing a safety risk. Summary of the Invention

[0003] The purpose of this invention is to provide a lightweight and stable double-drum mill structure.

[0004] The objective of this invention is achieved as follows: a lightweight double-drum winch structure, comprising a clutch assembly, a reducer assembly, and a drum assembly;

[0005] The clutch assembly consists of a clutch housing and a clutch output shaft located at the center of the clutch housing;

[0006] The speed reducer assembly consists of a speed reducer housing, a multi-stage planetary carrier, a speed reducer output shaft, and a speed reducer input shaft.

[0007] The drum assembly consists of a first drum and a second drum; the first drum is fixed on a first rotating shaft, and a drive gear is provided on the side of the first drum near the reducer assembly, the drive gear being fixedly connected to the first drum by bolts; the second drum is rotatably mounted on a second rotating shaft, and a driven gear is provided on the side of the second drum near the reducer assembly, the driven gear being fixedly connected to the second drum by bolts; a double-tooth transmission gear is provided between the driven gear and the drive gear.

[0008] Preferably, the clutch output shaft is connected to the reducer input shaft, and the reducer output shaft is connected to the first rotating shaft.

[0009] Preferably, the end of the first rotating shaft away from the reducer assembly is connected to the right side plate via a bearing, and both ends of the second rotating shaft are fixedly connected to the two side plates of the drum assembly.

[0010] Preferably, multiple sets of built-in bearings are provided between the second drum and the second rotating shaft.

[0011] Preferably, the double-tooth transmission gear consists of two sets of intermediate gears, which are rotatably connected to an intermediate shaft via bearings. The two ends of the intermediate shaft are fixed to the side plates on both sides of the drum assembly. The two sets of intermediate gears mesh with the driven gears and driving gears on both sides respectively, and there is a gap between the two sets of intermediate gears so that they do not mesh. The two sets of intermediate gears have the same size and their central axes are located on the same vertical plane.

[0012] Compared with the prior art, the advantages of the present invention are:

At the same time, it replaces single-tooth transmission with double-tooth transmission gears, with two sets of intermediate gears distributing the load, halving the force on a single set of gears, reducing wear and the risk of tooth breakage, extending gear life, and balancing lightweight design with transmission reliability.

For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0020] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0021] like Figure 1-2 As shown, a lightweight double-drum winch structure includes a clutch assembly 1, a reducer assembly 2, and a drum assembly 3;

[0022] The clutch assembly 1 consists of a clutch housing 101 and a clutch output shaft 102 located at the center of the clutch housing;

[0023] The reducer assembly 2 consists of a reducer housing 201, a multi-stage planetary carrier 202, a reducer output shaft 203, and a reducer input shaft 204.

[0024] The drum assembly 3 consists of a first drum 301 and a second drum 302. The first drum 301 is fixed on the first rotating shaft 4. The first drum 301 is provided with a drive gear 5 on the side near the reducer assembly 2. The drive gear 5 is connected to the first drum 301 by bolts. The second drum 302 is rotatably mounted on the second rotating shaft 6. The second drum 302 is provided with a driven gear 7 on the side near the reducer assembly 2. The driven gear 7 is fixedly connected to the second drum 302 by bolts. A double-tooth transmission gear 8 is provided between the driven gear 7 and the drive gear 5.

[0025] like Figure 1As shown, the clutch output shaft 102 is connected to the reducer input shaft 204, and the reducer output shaft 203 is connected to the first rotating shaft 4; the direct connection between the reducer output shaft and the first rotating shaft forms a power transmission path, ensuring efficient power transmission.

[0026] like Figure 1 As shown, the end of the first rotating shaft 4 away from the reducer assembly 2 is connected to the right side plate through a bearing, and the two ends of the second rotating shaft 6 are fixedly connected to the two side plates of the drum assembly 3. The first rotating shaft is the main drive shaft, with one end connected to the reducer and the other end placed on the bearing, which effectively avoids transmission deviation caused by shaft shaking during power transmission, reduces gear meshing clearance fluctuation, and ensures more stable power output during winch operation.

[0027] like Figure 1 As shown, multiple sets of built-in bearings are provided between the second drum 302 and the second rotating shaft 6; the layout is more compact, further reducing the weight of the drum assembly.

[0028] like Figure 1-2 As shown, the double-tooth transmission gear 8 consists of two sets of intermediate gears 801. The two sets of intermediate gears 801 are rotatably connected to the intermediate shaft 9 via bearings. The two ends of the intermediate shaft 9 are fixed to the side plates on both sides of the drum assembly 2. The two sets of intermediate gears 801 mesh with the driven gears 7 and the driving gears 5 on both sides, respectively, and there is a gap between the two sets of intermediate gears 801 so that they do not mesh. The two sets of intermediate gears 801 have the same size and their central axes are located on the same vertical plane. By using a double-tooth transmission gear instead of the traditional single-tooth transmission, the load borne by each set of intermediate gears is only about half that of the single-tooth transmission, which greatly reduces the stress on a single set of gears and extends the service life of the gears.

[0029] The working principle of this invention is explained as follows: Power is input through the clutch assembly, and the clutch output shaft transmits the power to the reducer input shaft. After the multi-stage planetary carrier of the reducer assembly reduces speed and increases torque, the power is transmitted to the first rotating shaft by the reducer output shaft. The first rotating shaft drives the first drum and the driving gear to rotate. The driving gear drives the driven gear through the double-tooth transmission gear, so that the second drum rotates synchronously, realizing the cooperative operation of the two drums.

[0030] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the concept and scope of the present invention. Various modifications and improvements made to the technical solutions of the present invention by those skilled in the art without departing from the inventive concept should fall within the protection scope of the present invention.
