Description

Technical Field

[0001] This utility model relates to the technical field of speed reducers, and in particular to a planetary gear reducer for a loader wheel-side axle. Background Technology

[0002] Wheel-side reducers are the final stage of speed reduction and torque amplification devices in automotive transmission systems. They are widely used in heavy-duty trucks, large buses, off-road vehicles, loaders, and other large industrial and mining vehicles. Planetary reducers are power transmission mechanisms that utilize gear speed converters to reduce the motor's rotational speed to the desired speed and obtain a larger torque. The planetary reducer uses a gear with fewer teeth on the drive shaft that meshes with a larger gear on the output shaft to achieve speed reduction. For example, the planetary gear reducer and vehicle described in prior art publication number CN208951233U include a planetary gear mechanism; multiple planetary gear mechanisms are arranged at intervals; the planet carrier of each planetary gear mechanism is connected to the sun gear of the adjacent planetary gear mechanism; and the ring gear of each planetary gear mechanism is fixed. The vehicle includes a drive motor, drive shaft, wheels, and the aforementioned planetary gear reducer; two drive motors are arranged side-by-side and coaxially; the drive motors, planetary gear reducers, drive shaft, and wheels are sequentially connected for transmission. However, it may generate some noise when running at high speed. If the planetary gears are not adequately lubricated, the planetary gear reducer will be damaged. At the same time, metal shavings will be present in the lubricating oil during operation, which will greatly shorten its service life. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a planetary gear reducer for loader wheel axles that can filter and block debris in lubricating oil to avoid internal wear and ensure long-term stable operation.

[0004] This utility model discloses a planetary gear reducer for a loader wheel-side axle, comprising a housing, an input shaft, an output shaft, a lubrication and filtering component, a discharge component, and a noise reduction component. The input shaft and output shaft are respectively installed on the left and right sides of the housing. A planetary gear set is arranged inside the housing. The lubrication and filtering component is installed inside the housing, and the discharge component is installed at the bottom of the housing. The noise reduction component is installed on the inner wall of the housing. Power is input and output through the input and output shafts. The lubrication and filtering component can lubricate and cool the planetary gear set while filtering and blocking debris in the lubricating oil. The discharge component facilitates regular inspection and replacement of the lubricating oil to ensure long-term stable operation. The noise reduction component can reduce operating noise to a certain extent.

[0005] Preferably, the lubrication and filtration component includes an inner liner and a filter screen. The inner liner is installed inside the housing, and its inner wall meshes with the planetary gear assembly. Multiple oil permeation grooves are provided on the left and right sides of the inner liner. The filter screen is installed at the bottom of the inner liner and connected to the inner wall of the housing. When the planetary gears are running, they agitate the internal lubricating oil, allowing it to flow through the oil permeation grooves inside the housing to lubricate and cool the planetary gear set. When the lubricating oil flows through the filter screen, the filter screen filters and blocks debris in the lubricating oil, preventing wear on the internal components.

[0006] Preferably, the discharge component includes a drain bolt, an oil drain hole is provided at the bottom of the housing, the drain bolt is screwed into the oil drain hole, and an oil collection groove is provided at the bottom of the inner wall of the housing; when the lubricating oil stops flowing, debris is deposited inside the oil collection groove, and unscrewing the drain bolt can discharge the waste oil and debris, which facilitates regular inspection of the lubricating oil quality and replacement of the lubricating oil, so as to ensure long-term stable operation.

[0007] Preferably, the noise reduction component includes two arc-shaped vibration damping plates, which are installed on the inner walls at both ends of the housing; the arc-shaped vibration damping plates can absorb the vibration generated by the operation of the planetary gear set, thereby reducing the operating noise to a certain extent.

[0008] Preferably, it also includes multiple reinforcing ribs, which are evenly installed on the outer wall of the shell; the multiple reinforcing ribs can increase the structural strength of the outer wall of the shell, increase the stability during use, and reduce deformation due to impact.

[0009] Preferably, it also includes an oil injection bolt, and an oil injection hole is provided on the top of the housing. The oil injection bolt is screwed into the oil injection hole. Unscrewing the oil injection bolt allows new lubricating oil to be injected into the housing through the oil injection hole, making it convenient to replace the lubricating oil.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: power is input and output through the input shaft and the output shaft; the lubrication and filtering component can lubricate and cool the planetary gear set while filtering and blocking debris in the lubricating oil; the discharge component facilitates regular inspection of lubricating oil quality and replacement of lubricating oil to ensure long-term stable operation; and the noise reduction component can reduce operating noise to a certain extent.

[0017] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.

[0018] like Figures 1 to 5 As shown, an input shaft 2 and an output shaft 3 are respectively installed on the left and right sides of the housing 1. A planetary gear set is set inside the housing 1. An inner liner 9 is installed inside the housing 1. The inner wall of the inner liner 9 meshes with the planetary gear assembly. Multiple oil permeable grooves are opened on the left and right sides of the inner liner 9. A filter screen 10 is installed at the bottom of the inner liner 9 and connected to the inner wall of the housing 1. An oil drain hole is opened at the bottom of the housing 1. An oil drain bolt 4 is screwed into the oil drain hole. An oil collection groove 7 is opened at the bottom of the inner wall of the housing 1. Two arc-shaped vibration damping plates 5 are installed on the inner walls of the front and rear ends of the housing 1. Multiple reinforcing ribs 6 are evenly installed on the outer wall of the housing 1. An oil injection hole is opened at the top of the housing 1. An oil injection bolt 8 is screwed into the oil injection hole.

[0019] When the planetary gears are running, they agitate the internal lubricating oil, which flows through the oil passage groove into the housing 1 to lubricate and cool the planetary gear set. When the lubricating oil flows through the filter screen 10, the filter screen 10 filters and blocks debris in the lubricating oil to prevent internal wear. When the lubricating oil stops flowing, the debris settles in the oil collection groove 7. Unscrewing the drain bolt 4 allows waste oil and debris to be discharged, facilitating regular checks on the quality of the lubricating oil and replacement of the lubricating oil to ensure long-term stable operation. The arc-shaped vibration damping plate 5 absorbs the vibration generated by the operation of the planetary gear set, reducing operating noise to a certain extent. Multiple reinforcing ribs 6 increase the structural strength of the outer wall of the housing 1, increasing stability during use and reducing deformation from impacts. Unscrewing the oil filling bolt 8 allows new lubricating oil to be injected into the housing 1 through the oil filling hole, facilitating lubricating oil replacement.
