[0034] Embodiment

[0035] As Figure 1 - Figure 2 As shown, the lubrication structure proposed by the embodiment of the present utility model includes:

[0036] A first connecting portion 1, on the side wall of the first connecting portion 1, a first external spline 2 is provided;

[0037] A second connecting portion 3, on the side wall of the second connecting portion 3, a second external spline 4 is provided. The first connecting portion 1 is connected to the second connecting portion 3. Inside the second connecting portion 3, a first channel 5 is provided. The first channel 5 extends in the direction of the end of the second connecting portion 3 away from the first connecting portion 1 and extends out of the second connecting portion 3. On the peripheral side wall of the first channel 5, an internal spline 7 is provided. On the surface of the second connecting portion 3 close to the first connecting portion 1, a second channel 6 is provided. The second channel 6 extends in the direction of the end of the first connecting portion 1 away from the second connecting portion 3 and extends out of the first connecting portion;

[0038] Wherein, the first external spline 2 of the first connecting portion 1 is used to connect to a power source, and the second external spline 4 and the internal spline 7 of the second connecting portion 3 are used to connect to a driving member driven by the power source.

[0039] Specifically, the spline is a standard structure. The splines are all multi-tooth parts. The spline on the inner surface is the internal spline 7, and the spline on the outer surface is the external spline.

[0040] The first external spline 2 of the first connecting portion 1 is used to connect with a power source having an internal spline 7, where the power source is, for example, the output shaft of a motor. The second external spline 4 of the second connecting portion 3 is used to connect with a driven device, where the driven device is, for example, a pulling stem roller and a screw conveyor, etc. An internal spline 7 is provided on the peripheral side wall of the first channel 5 of the second connecting portion 3, and the internal spline 7 is used to connect with an additional driven device. This structural design enables the device to connect two driven devices simultaneously to improve the usage effect of the device.

[0041] When the first external spline 2 of the first connecting portion 1 is connected to a power source having a similarly adapted spline, and the second external spline 4 and the internal spline 7 of the second connecting portion 3 are connected to a driven device having a similarly adapted spline, the power source can drive the first connecting portion 1 and the second connecting portion 3 to rotate synchronously, so that the driven device connected to the second connecting portion 3 can operate.

[0042] The first channel 5 cooperates with the second channel 6 to facilitate the supply of lubricating oil to the internal spline 7 located in the first channel 5, so that the internal spline 7 can always maintain a lubricated state. Among them, technicians can send the lubricating oil into the first channel 5 through the second channel 6. When the first connecting portion 1 and the second connecting portion 3 rotate with the power source, the lubricating oil entering the first channel 5 can lubricate the internal spline 7 and the parts in contact with the internal spline 7 synchronously. This structural design can improve the lubrication effect of the device and avoid problems such as leakage and uneven application of lubricating oil when technicians apply lubricating oil due to the internal spline 7 being located inside the first channel 5.

[0043] In a specific implementation, the first connecting portion 1, the second connecting portion 3, the first external spline 2, the second external spline 4, and the internal spline 7 are of an integral structure.

[0044] Specifically, the first connecting portion 1, the second connecting portion 3, the first external spline 2, the second external spline 4, and the internal spline 7 are processed into an integral structure by means of integral machining and casting. This structural design can improve the overall toughness of the device and avoid the phenomenon of fracture due to insufficient overall toughness of the device during use.

[0045] In a specific implementation, the first connecting portion 1, the second connecting portion 3, the first external spline 2, the second external spline 4, and the internal spline 7 are all made of metal materials.

[0046] Specifically, the metal material has the advantages of good heat resistance, not easy to burn; small change in properties with temperature change; high mechanical strength; good durability, not easy to age; not easy to be damaged, not easy to be contaminated with dust and dirt, etc.

[0047] Such as Figure 1 - Figure 2As shown, in a specific implementation, the first connecting portion 1 and the second connecting portion 3 are both cylindrical.

[0048] Specifically, this structural design can facilitate the device to be connected between a power source and a driven device.

[0049] like Figure 2 As shown, in a specific implementation, a third channel 9 is provided inside the first connection part, one end of the third channel 9 extends toward the direction where the end of the first connection part is away from the second connection part and extends out of the first connection part, the other end of the third channel 9 away from the one end is connected and communicated with the end of the second channel 6 away from the first channel 5, the diameter of the cross section of the third channel 9 along the first direction is larger than the diameter of the cross section of the second channel 6 along the first direction, and the diameter of the cross section of the first channel 5 along the first direction is larger than the diameter of the cross section of the third channel 9 along the first direction; wherein, the first direction is a direction perpendicular to the ground, and in a specific implementation, it also includes: an oil plug 8, which is inserted into the end of the second channel 6 away from the first channel 5 through the third channel 9.

[0050] Specifically, the caliber of the first channel 5 is larger than the caliber of the third channel 9, which is larger than the caliber of the second channel 6. First, the caliber of the third channel 9 is larger than the caliber of the second channel 6. This structural design can, on the one hand, facilitate technicians to add lubricating oil to the second channel 6 through the third channel 9. Second, since the caliber in the second channel 6 is smaller, it is convenient to increase the flow rate of the lubricating oil in the second channel 6, so that the lubricating oil entering the second channel 6 can quickly enter the third channel 9 and lubricate the internal spline 7 in the third channel 9; the caliber of the second channel 6 is smaller than the caliber of the first channel 5. This structural design can speed up the flow rate of the lubricating oil entering the second channel 6 into the third channel 9.

[0051] The oil plug 8 is used to block the intersection between the second channel 6 and the third channel 9 to prevent the lubricating oil from flowing back.

[0052] In a specific implementation, the oil plug 8 is made of rubber material.

[0053] Specifically, rubber material has multiple advantages such as good elasticity, wear resistance, corrosion resistance, water resistance, shock absorption and vibration reduction. The oil plug 8 made of rubber material can better seal the intersection between the second channel 6 and the third channel 9.

[0054] like Figure 2 As shown, in a specific implementation, the oil plug 8 includes:

[0055] A first tightening part 81 and a second tightening part 82 that are connected in sequence, the first tightening part 81 is located in the third channel 9, and the second tightening part 82 is located in the second channel 6;

[0056] Wherein, the first tightening part 81 and the second tightening part 82 are of an integral structure.

[0057] Specifically, the first tightening part 81 and the second tightening part 82 are made into an integral structure by means of integral machining and casting. This structural design can not only make the oil plug 8 as a whole have good sealing performance, but also achieve the effect of double sealing under the cooperation of the second tightening part 82 and the first tightening part 81. That is, the second tightening part 82 is inserted into the second channel 6, and the first tightening part 81 further seals the second channel 6 in which the second tightening part 82 is inserted, effectively improving the effect of the oil plug 8 blocking the intersection between the second channel 6 and the third channel 9 and enhancing the sealing performance of the device.

[0058] Such as Figure 2 As shown, in a specific implementation, the area enclosed by the cross-section of the first tightening part 81 along the first direction is smaller than the area enclosed by the cross-section of the third channel 9 along the first direction and larger than the area enclosed by the cross-section of the second channel 6 along the first direction;

[0059] The area enclosed by the cross-section of the second tightening part 82 along the first direction is larger than the area enclosed by the cross-section of the second channel 6 along the first direction and smaller than the area enclosed by the cross-section of the first tightening part 81 along the first direction.

[0060] Specifically, due to the fact that the oil plug 8 has a certain elasticity, this structural design can facilitate improving the blocking effect of the oil plug 8 on the intersection between the second channel 6 and the third channel 9.

[0061] When technicians need to lubricate the internal spline 7, they can manually pull out the oil plug 8 and add lubricating oil into the second channel 6 through the third channel 9. When the first connecting part 1 and the second connecting part 3 rotate with the power source, the lubricating oil entering the first channel 5 can lubricate the internal spline 7 and the parts in contact with the internal spline 7 synchronously. This structural design can improve the lubrication effect of the device and avoid problems such as leakage and uneven application of lubricating oil when technicians apply lubricating oil because the internal spline 7 is located inside the first channel 5. In addition, after the lubricating oil is added, technicians can block the intersection between the second channel 6 and the third channel 9 through the oil plug 8.

[0062] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
