Description

Technical Field

[0001] This utility model relates to the field of eccentric sleeves, and in particular to an adjustable eccentric sleeve assembly. Background Technology

[0002] An eccentric sleeve is a special type of mechanical part characterized by having one or more eccentric holes or flanges. Its main functions are support and guidance; it bears a certain load during operation, thus requiring a certain level of strength and wear resistance.

[0003] Existing eccentric sleeve components have a fixed eccentricity value at their axis, limiting their application to a single scenario. To address these issues, a solution is proposed below. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable eccentric sleeve assembly, which has the advantage of being able to freely adjust the position of the key pin block inside the key pin housing, thereby adjusting the eccentricity value of the eccentric sleeve.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] An adjustable eccentric sleeve assembly includes an eccentric outer ring, an eccentric inner ring, and an adjustable key pin. The eccentric inner ring is located inside the eccentric outer ring. A keyway is formed on the eccentric outer ring. The adjustable key pin is located inside the keyway and is fixedly connected to the eccentric outer ring. The eccentric inner ring is snapped and fixed to the adjustable key pin. The adjustable key pin includes a key pin housing and a key pin block. The key pin block is located inside the key pin housing and is movably connected to the key pin housing.

[0007] Preferably, the key pin housing has an internal thread on its inner wall, the key pin block has an external thread, and the key pin block is threadedly connected to the key pin housing.

[0008] Preferably, the end of the key block is provided with an anti-wear pad.

[0009] Preferably, the eccentric outer ring is provided with three or more keyways, the spacing between two adjacent keyways is the same, and each keyway is connected to an adjustable key pin.

[0010] Preferably, the eccentric inner ring includes several arc-shaped strips, each of which has the same length. The number of arc-shaped strips is the same as the number of keyways. The side wall of the key housing is provided with a slot. The two ends of the arc-shaped strips are respectively fixed to the slots of two adjacent key housings and are engaged and fixed with the key housing.

[0011] The beneficial effects of this utility model are as follows: by adjusting the position of multiple key pins, the external shaft can be fixed in different positions, and the deviation between the shaft center and the center of the eccentric inner ring can be adjusted; and the center position of the eccentric inner ring can also be adjusted by adjusting the position of different arc strips of the eccentric inner ring.

[0014] The following description is merely a preferred embodiment of this utility model, and the scope of protection is not limited to this embodiment. All technical solutions falling within the scope of this utility model's concept should be protected. Identical components are represented by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom" and "top," "inner" and "outer" refer to directions toward or away from the geometric center of a specific component.

[0015] like Figure 1 As shown, an adjustable eccentric sleeve assembly includes an eccentric outer ring 1, an eccentric inner ring 2, and an adjustable key pin 3. The adjustable key pin 3 includes a key pin housing 4 and a key pin block 5, with the key pin block 5 located inside the key pin housing 4. The eccentric outer ring 1 has at least three keyways; in this design, three are provided. The number of key pin housings 4 is the same as the number of keyways, and each keyway is connected to one key pin housing 4, with the key pin housing 4 fixedly connected to the keyway.

[0016] The key pin housing 4 has internal threads on its inner wall, and the key pin block 5 has external threads. The key pin block 5 is threadedly connected to the key pin housing 4. By rotating the key pin block 5, the length of the key pin block 5 extending out of the key pin housing 4 can be changed. The external connecting shaft 8 is inserted into the inner circle of the eccentric inner ring 2, and the three key pin blocks 5 abut against the connecting shaft 8, thus fixing the eccentric sleeve assembly to the external connecting shaft 8. By adjusting the length of the three key pin blocks 5 extending out of the corresponding key pin housing 4, the distance between the axis of the connecting shaft 8 and the center of the eccentric inner ring 2 can be changed, thereby changing the eccentricity value of the eccentric sleeve assembly.

[0017] The end of the key block 5 is provided with an anti-wear pad 6. The anti-wear pad 6 can not only prevent wear between the key block 5 and the external connecting shaft 8, but also increase the friction coefficient between the key block 5 and the connecting shaft 8, thereby increasing the reliability of the connection between the key block 5 and the connecting shaft 8.

[0018] The eccentric inner ring 2 comprises several arc-shaped strips 7, each of the same length. Each arc-shaped strip 7 can be arbitrarily engaged between two adjacent key pin housings 4. A slot is provided on the key pin housing 4, and the two ends of the arc-shaped strips 7 are fixed within the slot. In this design, the eccentric inner ring 2 consists of three arc-shaped strips 7, each with a different width, meaning the centers of the inner and outer circles of the eccentric inner ring 2 are not at the same position. By installing the three arc-shaped strips 7 in different positions, the eccentricity of the eccentric sleeve assembly can be initially adjusted before it is fixed to the external connecting shaft 8.

[0019] The specific embodiments described above further illustrate the technical problems, technical solutions, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
