Description

Technical Field

[0001] This utility model relates to the field of textile component technology, specifically a shuttle rotor with self-lubricating function. Background Technology

[0002] In the shuttle-feeding mechanism of a loom, the shuttle disc is driven to rotate by a power source, and the shuttle rotor is eccentrically mounted on the shuttle disc. When the shuttle disc rotates, the eccentrically mounted shuttle rotor performs a circular motion, its trajectory deviating from the central axis of the shuttle disc. This design causes the contact point and force direction between the shuttle rotor and components such as the shuttle rod to constantly change during rotation, thereby converting the rotational motion of the shuttle disc into the reciprocating oscillation of the shuttle rod, achieving the throwing action of the shuttle.

[0003] However, due to the continuous rotation of the shuttle rotor and the constant friction between them, the lubricating oil between them is consumed or evaporated, resulting in hard friction. Over time, this will wear down the shuttle rotor and shuttle disc, affecting their service life. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides a shuttle rotor with self-lubricating function, thus solving the problems mentioned in the background section.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a shuttle rotor with self-lubricating function, comprising a shuttle disc and a rotor, one side of the shuttle disc is used to connect to a power source, and the other side is eccentrically provided with a sleeve shaft for connecting the rotor, the sleeve shaft is a hollow lubrication cavity for storing lubricating oil, and the sleeve shaft is provided with a plurality of oil outlets circumferentially, each of the oil outlets being provided with a continuous oil outlet component, the inner ring of the rotor being in contact with the continuous oil outlet component.

[0008] Preferably, the continuous oil output assembly includes a lubricating ball, a sliding cavity, and a spring. The sliding cavity is arranged radially along the inside of the oil outlet. The lubricating ball is slidably fitted inside the sliding cavity. The diameter of the lubricating ball is larger than the diameter of the oil outlet. The spring is disposed inside the sliding cavity and located between the lubricating ball and the end of the sliding cavity. The bottom end of the sliding cavity is provided with a through hole.

[0009] Preferably, the inner ring of the rotor is provided with a plurality of arc-shaped bosses, the number of which is the same as that of the lubricating balls.

[0013] (III) Beneficial Effects

[0014] This invention provides a shuttle rotor with self-lubricating function. It has the following beneficial effects:

[0015] 1. This self-lubricating shuttle rotor, when the shuttle disc drives the rotor to rotate, the rotor will rotate relative to the sleeve shaft because the rotor is sleeved on the sleeve shaft. This causes mutual friction between the rotor and the lubricating ball. The continuous rotation of the lubricating ball can continuously carry out the lubricating oil in the lubrication cavity and wipe it on the inner wall of the rotor. As the rotor rotates, it slowly and continuously provides lubricating oil, reducing the friction between the rotor and the sleeve shaft and greatly extending the service life of the rotor.

[0021] This utility model embodiment provides a shuttle rotor with self-lubricating function, such as... Figure 1-4As shown, it includes a shuttle plate 1 and a rotor 2. One side of the shuttle plate 1 is used to connect to a power source, and the other side is eccentrically provided with a sleeve shaft 3 for connecting the rotor 2. The eccentrically provided rotor 2 is in contact with the shuttle rod, thereby converting the rotational motion of the shuttle plate into the reciprocating swing of the shuttle rod, realizing the throwing action of the shuttle.

[0022] In order to reduce the wear of rotor 2 and sleeve shaft 3 during long-term rotation, sleeve shaft 3 has a hollow lubrication cavity 4, which is used to store lubricating oil. Several oil outlets 8 are circumferentially opened on sleeve shaft 3.

[0023] like Figure 3-4 As shown, this utility model also includes a storage tank 5. The back of the shuttle disc 1 is provided with a threaded hole 6 that communicates with the lubrication chamber 4. The storage tank 5 is connected to the threaded hole 6 through a threaded post 7. The lubricating oil in the lubrication chamber 4 is replenished by the storage tank 5. When the lubricating oil in the lubrication chamber 4 is insufficient, it can be replenished by removing the storage tank 5.

[0024] Each oil outlet 8 is equipped with a continuous oil outlet component, and the inner ring of the rotor 2 is in contact with the continuous oil outlet component.

[0025] Specifically, such as Figure 4 As shown, the continuous oil supply assembly includes a lubricating ball 9, a sliding cavity 10, and a spring 11. The sliding cavity 10 is radially arranged inside the oil outlet 8. The lubricating ball 9 is slidably fitted within the sliding cavity 10. The diameter of the lubricating ball 9 is larger than the diameter of the oil outlet 8. By setting the diameter of the lubricating ball 9 to be larger than that of the oil outlet 8, the lubricating ball 9 as a whole will not slide out of the oil outlet 8, but a portion of the lubricating ball 9 can protrude outside the oil outlet 8 and contact the inner wall of the rotor 2. The spring 11 is disposed within the sliding cavity 10 and is located between the lubricating ball 9 and the end of the sliding cavity 10. The spring 11 does not directly contact the lubricating ball 9. A through hole is provided at the bottom end of the sliding cavity 10. Lubricating oil enters the sliding cavity 10 through the through hole and contacts the lubricating ball 9.

[0026] The inner ring of rotor 2 is provided with a number of arc-shaped protrusions 12, the same number as the lubricating balls 9. The arc-shaped protrusions 12 are arranged circumferentially at equal angles, and the distance between two adjacent arc-shaped protrusions 12 is greater than the diameter of the lubricating balls 9. Under normal conditions, when the lubricating balls 9 are all located in the gaps between two adjacent arc-shaped protrusions 12, the lubricating balls 9 are stationary. When the shuttle 1 drives rotor 2 to rotate, since rotor 2 is sleeved on shaft 3, rotor 2 will rotate relative to it, thus forming mutual friction with the lubricating balls 9. The continuous rotation of the lubricating balls 9 can continuously carry out the lubricating oil in the lubrication cavity 4 and wipe it on the inner wall of rotor 2. With the rotation of rotor 2, lubricating oil is slowly and continuously provided. When rotor 2 stops again, since the resistance provided by two adjacent arc-shaped protrusions 12 to the lubricating balls 9 is relatively large, the probability of the lubricating balls 9 staying in the gaps between two adjacent arc-shaped protrusions 12 is relatively high, preventing a large amount of lubricating oil from seeping out when stationary.

[0027] A limit component is provided at the outer end of the sleeve shaft 3 to prevent the rotor 2 from sliding out of the sleeve shaft 3.

[0028] like Figure 2 and Figure 4 As shown, the limiting assembly includes two sets of limiting blocks 13 and a second spring 15. A guide slide 14 is radially provided at the outer end of the sleeve shaft 3. The limiting block 13 slides within the guide slide 14. The second spring 15 is positioned between the end of the limiting block 13 located within the guide slide 14 and the inner end of the guide slide 14. One end of the limiting block 13 protrudes from the guide slide 14, and the side facing the outer end of the sleeve shaft 3 is an arc-shaped edge 16. Normally, the arc-shaped edge 16 near the outer end of the sleeve shaft 3 is positioned at the entrance of the guide slide 14. The back of the limiting block 13 is flat. When the rotor 2 is inserted, the rotor 2 presses against the arc-shaped edge 16, squeezing the limiting block 13 into the guide slide 14. When the rotor 2 is fully inserted into the sleeve shaft 3, the limiting block 13 extends under the action of the second spring 15, using the flat surface of the back of the limiting block 13 to limit the rotor 2 and prevent it from sliding out of the sleeve shaft 3.

[0029] 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.
