Description

Technical Field

[0001] This utility model relates to the field of speed reducer lubrication technology, and in particular to an anti-rotation joint structure for lubrication. Background Technology

[0002] During the operation of a gear reducer, ensuring proper lubrication of the bearings in the gears on the rotating shaft is crucial for maintaining its normal operation and performance.

[0003] Currently, the existing oil immersion lubrication method involves submerging the entire gear and bearing assembly in lubricating oil to ensure lubrication. While this method meets the basic lubrication requirements of the bearing, the rotation of the gears and bearings in the oil generates significant oil churning losses. The intense friction between the gears / bearings and the lubricating oil consumes a large amount of mechanical energy, directly reducing the transmission efficiency of the speed reducer. Secondly, the continuous churning of the lubricating oil by the gears and bearings causes the oil temperature to rise continuously. Excessively high lubricating oil temperatures not only alter its physical and chemical properties, leading to decreased lubrication performance, but also adversely affect other components within the speed reducer. Utility Model Content

[0004] The purpose of this invention is to provide an anti-rotation joint structure for lubrication, in order to solve the above-mentioned technical problems.

[0005] The technical solution adopted in this utility model is as follows:

[0006] A lubrication anti-rotation joint structure is provided for installation on a speed reducer. The speed reducer has a rotating shaft and includes a lubrication joint, an end cover, and a metal ring. The lubrication joint is installed on the end cover, and the end cover is installed on the speed reducer. One end of the lubrication joint extends into the rotating shaft, and the outer edge of one end of the lubrication joint is provided with the metal ring, which is a labyrinth seal ring.

[0007] Preferably, the other end of the lubrication joint is provided with a lubricating oil inlet.

[0008] As a further preferred embodiment, the lubrication joint has an axially arranged oil inlet hole inside, the lubricating oil inlet is connected to the oil inlet hole, and the inner diameter of the lubricating oil inlet is larger than the inner diameter of the oil inlet hole.

[0009] Preferably, the lubrication joint is further included with a first bolt, through which the lubrication joint is connected to the end cap.

[0010] Preferably, a second bolt is also included, through which the end cap is connected to the reducer.

[0011] Preferably, the reducer has a plurality of speed-changing gears inside, and the plurality of speed-changing gears are arranged on the rotating shaft, with two bearings respectively arranged between each speed-changing gear and the rotating shaft.

[0012] As a further preferred embodiment, the rotating shaft is provided with a rotating shaft oil hole in the middle, and an oil outlet hole is provided on the rotating shaft opposite the gear, and the oil outlet hole is connected to the rotating shaft oil hole.

[0013] The above technical solution has the following advantages or beneficial effects:

[0014] (1) In this utility model, by setting the anti-rotation joint structure, the lubricating oil can directly reach the contact part between the speed gear and the bearing through the lubrication joint, the rotating shaft oil hole and the oil outlet hole, which can greatly improve the lubrication quality of the bearing, ensure that the bearing is always in a good lubrication state during operation, effectively reduce the friction and wear between the internal components of the bearing, and thus significantly extend the service life of the bearing.

[0015] (2) In this utility model, lubricating oil can be directly injected into the rotating shaft through the anti-rotation joint. Then, the lubricating oil enters directly between the bearing and the gear through the oil outlet. This eliminates the oil immersion lubrication method, reduces the oil churning loss caused by the gear and bearing stirring in the oil, and the gear and bearing no longer need to overcome the additional resistance caused by the stirring of a large amount of lubricating oil. This allows mechanical energy to be transmitted more efficiently, thereby improving the transmission efficiency of the reducer. Attached Figure Description

[0022] Figure 1 This is a schematic diagram of the anti-rotation joint structure for lubrication and its cooperation with the speed reducer in this utility model; Figure 2 This is a structural diagram of the anti-rotation joint structure for lubrication in this utility model. Please refer to [link / reference]. Figures 1 to 2 The diagram illustrates a preferred embodiment of a lubrication anti-rotation joint structure for mounting on a speed reducer 1. The speed reducer 1 houses a rotating shaft 2. The joint includes a lubrication joint 3, an end cover 4, and a metal ring 5. The lubrication joint 3 is mounted on the end cover 4, which in turn is mounted on the speed reducer 1. One end of the lubrication joint 3 extends into the rotating shaft 2, providing a direct channel for delivering lubricating oil within the shaft 2, ensuring that the lubricating oil accurately reaches the areas requiring lubrication. A metal ring 5, a labyrinth seal ring, is provided on the outer edge of one end of the lubrication joint 3. The unique structure of the labyrinth seal ring effectively prevents lubricating oil leakage and blocks external impurities from entering, ensuring the sealing and cleanliness of the lubrication system.

[0023] Furthermore, as a preferred embodiment, the other end of the lubrication connector 3 is provided with a lubricating oil inlet 6. The inner wall of the lubricating oil inlet 6 may be provided with internal threads for threaded connection with an external oil pipe connector, facilitating the connection of an external lubricating oil source. The lubrication connector 3 has an axially oriented connector oil inlet hole 7 inside, which communicates with the lubricating oil inlet 6. The inner diameter of the lubricating oil inlet 6 is larger than the inner diameter of the connector oil inlet hole 7. This design helps the lubricating oil flow more smoothly into the connector oil inlet hole 7, reducing resistance caused by pipe diameter changes and improving oil inlet efficiency. In this embodiment, a one-way valve may be provided inside the connector oil inlet hole 7 to prevent lubricating oil inside the rotating shaft 2 from flowing out.

[0024] Furthermore, as a preferred embodiment, it also includes a first bolt 8. The lubrication connector 3 is connected to the end cover 4 via the first bolt 8, ensuring the stability of the connection between the two and preventing the lubrication connector 3 from loosening due to vibration or other factors during the operation of the reducer 1, thus affecting the lubrication effect. The end cover 4 is connected to the reducer 1 via a second bolt 9, further ensuring a reliable connection between the entire structure and the reducer 1.

[0025] Furthermore, as a preferred embodiment, the reducer 1 is internally equipped with several gears 10, which are mounted on the rotating shaft 2. Each gear 10 has two bearings 11 positioned between it and the rotating shaft 2. An oil hole is located in the center of the rotating shaft 2, and an oil outlet 13 is located on the rotating shaft 2 opposite the gears 10. The oil outlet 13 communicates with the oil hole, allowing the lubricating oil entering the rotating shaft 2 from the lubrication joint 3 to flow precisely to the contact area between the gears 10 and the bearings 11 through the oil hole and the oil outlet 13. This achieves precise lubrication of the bearings 11, changing the previous uneven distribution and significant waste of lubricating oil under the immersion lubrication method.

[0026] In this embodiment, the lubrication problem of the bearing 11 of the gear 10 on the rotating shaft 2 in the gear shift reducer 1 is solved by setting the anti-rotation joint structure and the oil hole and oil outlet hole 13 in the rotating shaft 2. While ensuring sufficient lubrication, the oil churning loss of gears and bearings 11 is reduced, the negative impact of the increase in lubricating oil temperature is reduced, the transmission efficiency of the reducer 1 is improved, the service life of the reducer 1 is extended, and the overall performance of the reducer 1 is improved.

[0027] In use, connect the external oil pipe connector to the lubricating oil inlet 6, and then inject lubricating oil into the oil inlet hole 7 of the connector. The lubricating oil enters the oil hole of the rotating shaft 2, and then enters the space between the gear 10 and the bearing 11 through the oil outlet hole 13, thereby lubricating the gear 10 and the bearing 11.

[0028] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model. Those skilled in the art should realize that all solutions obtained by equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
