[0026] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Example 1

[0028] like Figures 1 to 5 This embodiment proposes a noise reduction gearbox for a silage machine, including a gearbox 1. A left shell 2 is provided on the side of the gearbox 1. A noise reduction component 3 is provided on the inner wall of the gearbox 1. The noise reduction component 3 includes a right shell 31. The side of the right shell 31 is provided on the side of the gearbox 1. An upper output shaft 32 is provided on the inner wall of the gearbox 1, an intermediate gear 33 is provided on the inner wall of the gearbox 1, an output pinion 34 is provided on the inner wall of the gearbox 1, an output spark hole shaft 35 is provided on the inner wall of the gearbox 1, a joint bearing 310 is provided on the inner wall of the gearbox 1, and a lower output bevel gear shaft 37 is provided on the inner wall of the gearbox 1.

[0029] An output large gear 38 is provided on the inner wall of the gear box 1 , an output flange 39 is provided on the inner wall of the gear box 1 , and a spherical bearing 310 is provided on the inner wall of the gear box 1 . The design of the spherical bearing 310 is conducive to providing good support.

[0030] Two intermediate gears 33 are provided and arranged along a linear array on the inner wall of the gear box 1 . The left shell 2 is made of aluminum alloy. The aluminum alloy material of the left shell 2 is beneficial to reducing the weight of the gear box 1 .

[0031] The right shell 31 is made of aluminum alloy, the upper output shaft 32 is located above the intermediate gear 33, the left shell 2 and the right shell 31 are symmetrical to each other along the vertical center axis of the gearbox 1, and the design of the left shell 2 and the right shell 31 is conducive to protecting the outer wall of the gearbox 1.

[0032] The gearbox 1 is provided with two input ends and five output ends. The spherical bearing 310 is made of metal. The lower output bevel gear shaft 37 is located below the output spark hole shaft 35. The spherical bearing 310 made of metal has stronger support.

[0033] In this embodiment, the present application replaces the components in the imported gearbox 1 with the upper output shaft 32, intermediate gear 33, output pinion 34, output spark hole shaft 35, lower output bevel gear shaft 37, output gear 38, output flange 39, and spherical bearing 310 in the noise reduction 3 components. There are two input ends and five output ends. The two input ends can achieve power load balance, reduce the pressure of a single input source, and extend the service life of the equipment. The five output ends can distribute power to multiple working parts to meet different operating requirements. For example, in a silage machine, cutting, compression, conveying and other auxiliary systems can be driven simultaneously to improve work efficiency. When designing the gears, the shape and whitening are improved to improve strength and reduce noise. The left and right shells 31 are made of natural metal materials to reduce weight.

[0034] Example 2

[0035] like Figures 3 to 5 Based on the same concept as the above-mentioned embodiment 1, this embodiment also proposes another embodiment. A lubrication and noise reduction component 4 is provided on the inner wall of the gear box 1. The lubrication and noise reduction component 4 includes a control box 41. The side of the control box 41 is fixedly connected to the inner wall of the gear box 1. A fixed block 42 is fixedly connected to the inner wall of the control box 41. A moving block 43 is slidably connected to the inner wall of the control box 41. A push rod 44 is fixedly connected to the side of the moving block 43. The end of the push rod 44 away from the moving block 43 passes through the side of the control box 41. An oil outlet pipe 47 passes through the side of the control box 41. The different gears of different sizes inside the gear box 1 are lubricated by lubricating oil to reduce friction and reduce noise.

[0036] A connecting pipe 48 passes through the side of the control box 41 , and an oil tank 49 passes through the end of the connecting pipe 48 away from the control box 41 . The oil tank 49 is located above the control box 41 . The design of the oil tank 49 is conducive to replenishing lubricating oil to the control box 41 .

[0037] A spring 46 is fixedly connected to the side of the moving block 43 , and one end of the spring 46 away from the moving block 43 is fixedly connected to the inner wall of the control box 41 .

[0038] A limiting rod 45 is fixedly connected to the inner wall of the control box 41. The end of the limiting rod 45 away from the control box 41 passes through the side of the moving block 43. The design of the limiting rod 45 is conducive to limiting the moving block 43 and restricting the displacement trajectory of the moving block 43.

[0039] There are two fixed blocks 42, and they are symmetrical to each other along the vertical center axis of the movable block 43. A replenishing pipe 410 passes through the oil tank 49. The end of the replenishing pipe 410 away from the oil tank 49 passes through the side of the gear box 1. The design of the replenishing pipe 410 is conducive to replenishing the interior of the oil tank 49.

[0040] In this embodiment, when the gears inside the gearbox 1 have been used for a long time and friction occurs, the push rod 44 is pushed toward the side close to the gearbox 1. The movement of the push rod 44 will push the moving block 43. The moving block 43 and the two fixed blocks 42 form a baffle inside the control box 41. The lubricating oil in the oil tank 49 is transferred into the interior of the control box 41 through the connecting pipe 48. At this time, the lubricating oil is blocked by the baffle. The lubricating oil is located on the right side of the control box 41, and the oil outlet pipe 47 is located on the left side of the baffle. Therefore, the lubricating oil cannot flow out. When the moving block 43 moves, a gap is opened in the baffle, allowing the lubricating oil to flow out from the gap. The outflowing lubricating oil will flow to the left side of the baffle, and then flow out through the oil outlet pipe 47. The oil outlet pipe 47 is located on the side of the gear. The outflowing lubricating oil will lubricate the gear, reduce the friction between the gears, and reduce noise. By regularly supplying lubricating oil to the gears, the friction between the gears can be significantly reduced and wear can be reduced. This is crucial for extending the life of gears and maintaining their performance. Good lubrication can reduce power loss, improve transmission efficiency, and ensure that the gearbox can maintain stable operation under high load conditions. The inflow of lubricating oil helps reduce noise during gear operation. The oil film formed by the lubricating oil on the gear contact surface can absorb some vibration, thereby reducing noise.

[0041] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
