DETAILED DESCRIPTION

[0032] The following will be described in detail in combination with the accompanying drawings. Figures 1-2 The application will be further described in detail.

[0033] The embodiment of the application discloses a transmission chain lubricating device.

[0034] Reference Figure 1 A transmission chain lubricating device comprises a workbench 1, a lubricating pipe 3 slidably installed on the workbench 1, a lubricating assembly 4 installed on the workbench 1 by bolts, and an oil supply assembly for supplying oil to the lubricating pipe 3 and the lubricating assembly 4.

[0035] In the process of lubricating the sleeve 2, the sleeve 2 is sleeved on the lubricating pipe 3, and then the lubricating pipe 3 is driven to move towards the lubricating assembly 4, so that the outer wall of the sleeve 2 abuts against the lubricating pipe 3. The lubricating assembly 4 drives the sleeve 2 to rotate along the axis of the lubricating pipe 3, and at the same time, the oil supply assembly supplies lubricating oil to the lubricating pipe 3 and the lubricating assembly 4. The lubricating pipe 3 applies the lubricating oil to the inner wall of the sleeve 2, and the lubricating assembly 4 applies the lubricating assembly 4 to the outer wall of the sleeve 2, so as to realize the application of the lubricating oil to the outer surface of the sleeve 2. The operation is simple and convenient, the lubricating oil is applied quickly and uniformly, and the problem of low lubricating oil application efficiency of the sleeve 2 surface is improved.

[0036] Referring to Figure 1 and Figure 2 , the metal pipe at the bottom end of the lubricating pipe 3 is welded and installed with a sliding seat, and a sliding groove is formed on the workbench 1, and the sliding seat is slidingly installed in the sliding groove. A plurality of oil holes 6 are uniformly formed on the outer wall of the lubricating pipe 3, and the oil holes 6 communicate the outside with the lumen of the lubricating pipe 3. A guide slope 15 is formed at the top of the lubricating pipe 3, which facilitates the sleeving of the sleeve 2 on the lubricating pipe 3. The oil supply assembly pumps 52 lubricating oil into the lumen of the lubricating pipe 3 through the pipeline, and the lubricating oil flows out of the oil holes 6 and adheres to the inner wall of the sleeve 2, thereby realizing the lubrication of the inner wall of the sleeve 2.

[0037] The lubricating assembly 4 comprises a driving member 42 fixedly installed on the workbench 1 by bolts and an abutting wheel 41 installed at the end of the driving member 42 by screws. In the embodiment of the application, the driving member 42 is a driving motor, and an installation disc is arranged on the output shaft of the driving motor, and the abutting wheel 41 is installed on the end face of the installation disc by screws.

[0038] The abutting wheel 41 is a flexible rubber wheel, which is a hollow cylinder with one end open, and the open end is located at the end away from the installation disc. An accommodating cavity 7 is formed between the inner walls of the abutting wheel 41, and a plurality of lubricating holes 8 are formed through the outer peripheral wall, and the two ends of the lubricating holes 8 are respectively communicated with the accommodating cavity 7 and the outside. The flexible rubber wheel itself has a large surface friction, which facilitates the rotation of the sleeve 2, and at the same time, the rubber wheel has good damping performance, which prevents the sleeve 2 from being rigidly collided with the abutting wheel 41 during abutting, thereby reducing the damage to the sleeve 2.

The cover plate 9 seals the accommodating cavity 7, thereby reducing the risk of splashing of the lubricating oil in the accommodating cavity 7 at the open end of the abutting wheel 41. At the same time, the oil pumping assembly 5 supplies oil to the abutting wheel 41 during the rotation of the abutting wheel 41.

[0040] The oil pumping assembly 5 comprises an oil tank 51 and an oil pump 52, which are fixedly installed on the workbench 1 by bolts, and rubber oil pipes are arranged between the oil outlet of the oil tank 51 and the oil inlet of the oil pump 52 and between the oil outlet hole 6 of the oil pump 52 and the oil conveying pipe 10.

[0042] When the driving member 42 drives the oil pump 52 to work, the driving member 42 drives the driving gear 13 to rotate, the driving gear 13 drives the driven gear 12 to rotate, the driven gear 12 drives the transmission rod 11 to rotate, the transmission rod 11 drives the oil pump 52 to rotate through the coupling 14, and oil supply of the oil pumping assembly 5 is realized.

[0043] The oil collecting tank 17 is bolted on the workbench 1, and a guard plate 16 is integrally formed on the oil collecting tank 17 and surrounds the position close to the abutting wheel 41. During the rotation of the abutting wheel 41, the lubricating oil in the containing cavity 7 is affected by the pressure of the oil pump 52 and the centrifugal force, so that the lubricating oil splashes along the lubricating hole 8, the guard plate 16 blocks the splashed lubricating oil, and the splashed lubricating oil flows into the oil collecting tank 17 under the action of gravity, so that the lubricating oil is recycled and reused.

[0044] The implementation principle of the transmission chain lubricating device is as follows: when the sleeve 2 of the transmission chain is lubricated, the sleeve 2 is sleeved on the lubricating pipe 3, then the lubricating pipe 3 is moved towards the abutting wheel 41 until the abutting wheel 41 abuts against the outer wall of the sleeve 2, then the driving member 42 works to drive the abutting wheel 41 to rotate, and the oil pump 52 works to pump lubricating oil into the abutting wheel 41 and the lubricating pipe 3, the lubricating oil is pumped out of the lubricating pipe 3 and adheres to the inner wall of the sleeve 2, the lubricating oil is pumped out of the abutting wheel 41 and adheres to the outer wall of the sleeve 2, and the abutting wheel 41 drives the sleeve 2 to rotate, so that the sleeve 2 has the same linear velocity as the abutting wheel 41, the lubricating oil adheres to the outer wall of the sleeve 2, and the sleeve 2 is fully lubricated.
