Specific implementation manners

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1-3 , an embodiment of the present utility model provides a technical solution: a transmission shaft with a lubrication structure, including a device body 1. The device body 1 includes a driver 2, a lubrication chamber 3, a transmission shaft 4, a mounting seat 5 and a lubricator 6. The lubrication chamber 3 is welded to the front end of the driver 2. The transmission shaft 4 is installed in the lubrication chamber 3 and is connected to the driving end of the driver 2. The mounting seat 5 is welded and fixed above the front end of the driver 2. The lubricator 6 is installed on the top of the mounting seat 5;

[0021] This is solved by the lubricator 6 which includes a filter chamber 11, an oil transfer pump body 12, a first transfer pipe 13 and a second transfer pipe 14. The filter chamber 11 is in a cylindrical structure. The oil transfer pump body 12 is installed at the inner top end of the filter chamber 11. The first transfer pipe 13 is installed at the input end of the oil transfer pump body 12. The second transfer pipe 14 is installed at the bottom of the filter chamber 11. A group of filter meshes 15 are arranged in the filter chamber 11 in a columnar and equally spaced manner. When filtering and recycling the lubricating oil in the lubricating chamber 3, the staff starts the oil transfer pump body 12 in the lubricator 6. After the oil transfer pump body 12 starts, it pumps out the lubricating oil at the bottom of the lubricating chamber 3. The lubricating oil can be drawn into the filter chamber 11 through the first transfer pipe 13. When the lubricating oil passes through the group of filter meshes 15 in the filter chamber 11, the filter meshes 15 can effectively filter out the impurities in the lubricating oil, further improving the purity of the lubricating oil. The filtered lubricating oil is transported into the lubricating chamber 3 through the second transfer pipe 14, and further lubrication work can be carried out at the connection between the drive and the remaining transmission shafts 4.

[0022] Furthermore, the lubricating chamber 3 is in a cylindrical structure and both the front and rear ends are through structures. An oil inlet 9 is provided at the top of the lubricating chamber 3 and an oil outlet 10 is provided at the bottom. The oil inlet 9 is for facilitating the input of the lubricating oil into the lubricating chamber 3, and the oil outlet 9 is for facilitating the extraction and filtration of the lubricating oil in the lubricating chamber 4.

[0023] Differently, a sealing cover 7 is provided at the front end of the lubricating chamber 3. The sealing cover 7 is in a funnel-shaped structure. A sealing ring 8 is provided at the front end of the sealing cover 7. The sealing cover 7 and the sealing ring 8 are for improving the sealing performance after connection and preventing dust from entering the lubricating chamber 3 to contaminate the lubricating oil.

[0024] Effectively, the input end of the first transfer pipe 13 is connected to the oil inlet 9, and the bottom output end of the second transfer pipe 14 is connected to the oil outlet 10. The first transfer pipe 13 is for transporting the lubricating oil in the lubricating chamber 3 into the lubricator 6 for filtration, and the second transfer pipe 14 is for re-discharging the filtered lubricating oil into the lubricating chamber 3 for lubrication.

[0025] Working principle: During operation, when filtering and recycling the lubricating oil in the lubricating chamber 3, the staff starts the oil transfer pump body 12 in the lubricator 6. After the oil transfer pump body 12 starts, it pumps out the lubricating oil at the bottom of the lubricating chamber 3. The lubricating oil can be drawn into the filter chamber 11 through the first transfer pipe 13. When the lubricating oil passes through the group of filter meshes 15 in the filter chamber 11, the filter meshes 15 can effectively filter out the impurities in the lubricating oil, further improving the purity of the lubricating oil. The filtered lubricating oil is transported into the lubricating chamber 3 through the second transfer pipe 14, and further lubrication work can be carried out at the connection between the drive and the remaining transmission shafts 4.

Through the mutual combination of the above components, the present utility model can effectively lubricate the connection between the transmission shaft and the drive shaft. This lubrication method uses lubricating oil for lubrication.
