Description

Technical Field

[0001] This utility model relates to the field of bushing technology, and in particular to a multi-oil-channel self-lubricating bushing. Background Technology

[0002] Patent document CN220337294U discloses a wear-resistant bushing for a classifier, specifically relating to the field of bushings. It includes a bushing body with sheaths fixedly connected to both sides. The sheaths have equidistant oil inlets on their surfaces, and soft rubber sheets are movably installed inside each inlet. This invention, through its structural design of the sheath, oil inlets, soft rubber sheets, oil storage pipe, oil outlet, and drainage groove, allows the user to inject lubricating oil into the oil storage pipe via the oil inlets using a syringe. The soft rubber sheets inside the oil inlets provide a leak-proof seal. The lubricating oil then flows through a connecting pipe and into the bushing groove via the oil outlet. The lubricating oil then flows along the drainage groove until it is full, improving the wear resistance of the bushing body and thus enhancing the classifier's working efficiency while ensuring its service life and meeting the user's needs for using the classifier.

[0003] However, the oil grooves in this bushing structure are not interconnected, resulting in uneven distribution of lubricating oil during bushing rotation. This leads to insufficient lubrication in some areas, affecting the service life of the bushing. Therefore, it is necessary to improve this structure to overcome these defects. Utility Model Content

[0004] The purpose of this invention is to provide a multi-oil-channel self-lubricating bushing to solve the problems mentioned in the background art.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0031] Example 1

[0032] like Figure 1-3 As shown, the present invention proposes a multi-oil-path self-lubricating bushing, including a support member, a limiting assembly member, an external lubrication member, and an internal lubrication member. The support member is cylindrical in shape and can be fitted with a shaft. The limiting assembly member is formed in the support assembly and is connected to the assembly component. The external lubrication member is formed on the surface of the support member and lubricates the surface of the support member. The internal lubrication member is formed on the inner surface of the support member and ensures the lubrication inside the support member.

[0033] In this embodiment, the support member includes a bearing sleeve 110, which has a cylindrical cross-section and an assembly space in the middle.

[0034] In this embodiment, the limiting assembly component includes a limiting groove 210, which is formed in the bearing sleeve. The limiting groove is cylindrical in shape and is recessed radially into the bearing sleeve. The limiting groove limits the assembly component.

[0035] In this embodiment, the external lubrication component includes an inclined oil groove 310 and a through oil hole 320. The inclined oil groove is formed on the outer surface of the bearing sleeve. The inclined oil groove is recessed towards the inside of the bearing sleeve and is inclined on the surface of the bearing sleeve. The inclined oil groove lubricates the outer surface of the bearing sleeve. The through oil hole is formed in the bearing sleeve. There is a set of through oil holes. The through oil hole penetrates the bearing sleeve radially, thereby connecting the inner side and the outer side of the bearing sleeve.

[0036] In this embodiment, the internal lubrication component includes an inner guide groove 410 and an inner concave annular groove 420. The inner guide groove is formed on the inner surface of the bearing sleeve and is recessed radially toward the outer side of the bearing sleeve. The front end of the inner guide groove extends axially, and the rear end of the inner guide groove is inclined. The inner guide groove lubricates the inner side of the bearing sleeve. The front end of the inner guide groove is parallel to the axis, which increases the lubrication uniformity at the front end. The rear end of the inner guide groove is inclined to the axis, which effectively ensures that the bearing sleeve can adapt to medium speed and medium load applications. The inner concave annular groove is formed on the inner surface of the bearing sleeve and is connected to the rear end of the inner guide groove. The inner concave annular groove connects all the inner guide grooves, thereby ensuring the uniformity of lubricant distribution.

[0037] In this embodiment, the bearing sleeve is made of copper alloy.

[0038] Example 2

[0039] like Figure 1-4 As shown, the difference between this embodiment and Embodiment 1 is that the external lubrication assembly also includes an external connecting ring groove 330. This external connecting ring groove is formed at the bottom of the inclined oil groove, thereby connecting the various inclined oil grooves and making the lubricating oil on the outer surface of the bearing sleeve more evenly distributed. This effectively avoids insufficient lubrication in some areas. At the same time, by setting the external connecting ring groove, the storage capacity of the bearing sleeve lubricating oil is effectively increased, and the number of times the lubricating oil needs to be added is reduced.
