The connecting member 3 includes a cylinder 31, a connecting pipe 32, a first rubber sealing ring 33, a sealing cap 34, a sliding plug 35, and a second rubber sealing ring 36. A connecting pipe 32 is fixedly located at the bottom end of the cylinder 31. A first rubber sealing ring 33 is fixedly located between the bottom end of the cylinder 31 and the top of the connecting pipe 32. A sealing cap 34 is fixedly located on the upper inner wall of the cylinder 31. A sliding plug 35 is slidably disposed inside the sealing cap 34. A second rubber sealing ring 36 is fixedly located inside the sealing cap 34. The cover 4 includes a cover shell 4. 1. A first twist block 42 and a pressure column 43 are provided. The first twist block 42 is fixedly installed at the top of the cover shell 41, and the pressure column 43 is fixedly installed on the inner wall of the top of the cover shell 41. The core body 5 includes a column cylinder 51, a third rubber sealing ring 52, a fourth rubber sealing ring 53, a lower silicone ring 54, an upper silicone ring 55, a filter element 56, an assembly cover 57, and a second twist block 58. The third rubber sealing ring 52 is fixedly installed on the outer side below the column cylinder 51, and the fourth rubber sealing ring 53 is fixedly installed on the outer side above the column cylinder 51. The inner wall of the column cylinder 51 is slidably placed with the lower silicone ring 54 and the upper silicone ring 55. The filter element 56 is fixedly installed between the top of the lower silicone ring 54 and the bottom of the upper silicone ring 55. The threaded line on the outer side above the column cylinder 51 is assembled with the internal thread of the assembly cover 57. The top of the upper silicone ring 55 is in contact with the assembly cover 57. The second twist block 58 is fixedly installed at the top of the assembly cover 57.

[0028] The bottom of the connecting pipe 32 is fixedly connected to the top of the device housing 1. When the connecting part 3 and the core 5 are assembled and placed, the inner side of the first rubber sealing ring 33 is in contact with the outer side of the third rubber sealing ring 52, and the inner side of the second rubber sealing ring 36 is in contact with the outer side of the fourth rubber sealing ring 53. The above arrangement facilitates the assembly and placement of the connecting part 3 and the core 5.

[0029] When the connecting part 3 and the cover 4 are assembled, the threaded line on the outer side of the upper part of the cylinder 31 is connected to the threaded line on the inner wall of the cover 41. This arrangement facilitates the assembly and placement of the connecting part 3 and the cover 4.

[0030] After the connecting piece 3 and the cover 4 are assembled and placed, the bottom end of the pressure column 43 is in contact with the top end of the second twist block 58. Through the above arrangement, the pressure column 43 plays a role in vertically pressing and limiting the core 5.

[0031] The cylinder 31 and the top pipe of the circulating pump 2 are fixedly connected by a rigid pipe. With the above configuration, the circulating pump 2 is a fluid delivery pump for the lubricating oil inside the housing of the electric drive bridge reducer.

[0032] Work process: This utility model provides a lubrication and filtration structure for the housing assembly of an electric drive bridge reducer. The assembled structure of the main body of the device makes it easy to periodically disassemble and replace the internal filter element 56.

[0033] The circulating pump 2 in the device is a fluid transfer pump for the lubricating oil inside the housing of the electric drive bridge reducer. It is a common device in the prior art and will not be described in detail here. The circulating pump 2 is controlled by an external controller and powered by an external power source.

[0034] The lower silicone ring 54, upper silicone ring 55, and filter element 56 of this device are integrated filter components. When the integrated filter components are installed inside the core 5, the lower silicone ring 54 and upper silicone ring 55 are slidably placed on the inner wall of the column 51. The second torsion block 58 is manually rotated, and the inside of the assembly cover 57 is threaded with the threaded line on the upper outer side of the column 51 until the top of the upper silicone ring 55 is in contact with the assembly cover 57.

[0035] When the connecting piece 3 and the core 5 are assembled and placed, the inner side of the first rubber sealing ring 33 is in contact with the outer side of the third rubber sealing ring 52, and the inner side of the second rubber sealing ring 36 is in contact with the outer side of the fourth rubber sealing ring 53. The sliding plug 35 is pulled out, and lubricating oil is added into the cylinder 31. The lubricating oil fills the inside of the device housing 1, the inside of the connecting pipe 32, and the inside of the cylinder 31.

[0036] When the connecting part 3 is assembled with the cover 4, the first torsion block 42 is manually rotated, and the threaded line on the outer side of the upper part of the cylinder 31 is engaged with the threaded line on the inner wall of the cover 41 until the bottom end of the pressure column 43 is in contact with the top end of the second torsion block 58, thus completing the installation of the device.

[0037] The circulation pump 2 starts and draws the lubricating oil inside the cylinder 31 back into the device housing 1, forming a guide and conveying system for the lubricating oil. The filter element 56 adsorbs and filters the small amount of gear wear debris attached to the lubricating oil to maintain the cleanliness of the gear lubricating oil.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
