Abstract
Description
Technical Field
[0001] This utility model belongs to the field of bearing technology, and more specifically, it relates to a grease self-lubricating bearing. Background Technology
[0002] As a key component in mechanical transmission systems, bearings play an indispensable role in many industrial fields. Their performance directly affects the operational stability, efficiency, and service life of the entire mechanical equipment. Traditional bearings usually rely on external lubrication systems to provide lubricating grease during operation in order to reduce friction, reduce wear, and ensure the normal operation of the bearings.
[0003] Traditional bearings mostly rely on periodically adding lubricating grease to maintain normal operation. However, adding lubricating grease requires stopping the machine, which can seriously affect the production efficiency of continuously operating machinery. In addition, manually adding lubricating grease also has the problem of uneven addition. Too much or too little lubricating grease will have an adverse effect on the operation of the bearing. Too much may lead to increased bearing resistance and temperature, while too little will not effectively reduce friction and wear. Utility Model Content
[0004] To address the aforementioned technical problems, this utility model provides a grease-based self-lubricating bearing, which solves the problems mentioned in the background art, such as the need to stop the machine during the addition of lubricating grease and the uneven amount added.
[0005] This utility model discloses a grease-based self-lubricating bearing, achieved through the following specific technical means: A grease-lubricated bearing includes an outer ring and an inner ring; an auxiliary component is provided between the outer ring and the inner ring, and a protective structure is also provided between the outer ring and the inner ring; the outer ring is filled with solid lubricating grease A, and the inner ring is filled with solid lubricating grease B, and both solid lubricating grease A and solid lubricating grease B are arranged in a ring shape. The bearing inner ring has a lower retaining edge fixedly installed on the outer side of its bottom, and a threaded hole A is opened inside the top side of the bearing inner ring; a positioning hole is also opened inside the top side of the bearing inner ring, and the positioning hole and the threaded hole A are arranged in a ring array; a positioning post is slidably installed inside the positioning hole, and an upper retaining edge of the inner ring is fixedly installed at the top of the positioning post; a fixing ring is fixedly installed on both the upper retaining edge of the inner ring and the outer side of the bearing inner ring, and a graphite ring is fixedly installed on the fixing ring.
[0006] Furthermore, an outer ring retainer is fixedly provided inside the outer ring of the bearing, and two sets of outer ring retainers are symmetrically arranged; a threaded hole B is opened inside the top side of the outer ring of the bearing, and the threaded hole B is arranged in a ring array.
[0007] Furthermore, the inner ring upper flange has a connecting hole inside, and the connecting holes are arranged in a ring array; an internal hexagonal bolt A is movably disposed inside the connecting hole, and the internal hexagonal bolt A is disposed inside the threaded hole A through a threaded connection.
[0008] Furthermore, the auxiliary components include: a lower cage, a pocket, a rivet, an upper cage, an auxiliary hole, and a cylindrical roller; the lower cage is disposed between the outer ring and the inner ring of the bearing; the pocket is opened inside the lower cage; the rivet is fixedly disposed on the top of the lower cage; the upper cage is movably disposed on the top of the lower cage; the auxiliary hole is opened inside the upper cage, and a rivet is disposed inside the auxiliary hole; the cylindrical roller is movably disposed inside the pocket, and the outer side of the cylindrical roller is in contact with the outer side of solid lubricating grease A and solid lubricating grease B.
[0009] Furthermore, the auxiliary component also includes: an auxiliary slot; the auxiliary slot is formed inside the lower retainer and is located on both sides of the pocket.
[0010] Furthermore, the protective structure includes: a protective ring frame, a mounting base, a hexagon socket bolt B, and a dustproof mesh frame; the protective ring frame is fixedly installed on the outer side of the bearing outer ring; the mounting base is fixedly installed on the outer side of the protective ring frame; the hexagon socket bolt B is movably installed inside the mounting base, and the hexagon socket bolt B is threaded into the threaded hole B; the dustproof mesh frame is fixedly installed on the top of the protective ring frame, and the bottom of the dustproof mesh frame is in contact with the top of the graphite ring, and the dustproof mesh frame is located between the bearing outer ring and the bearing inner ring.
[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. In this utility model, by providing annular solid lubricating grease A and solid lubricating grease B, friction occurs between the cylindrical roller and solid lubricating grease A and solid lubricating grease B during the operation of the cylindrical roller, causing solid lubricating grease A and solid lubricating grease B to melt upon heating. Consequently, solid lubricating grease A and solid lubricating grease B can continuously and stably release lubricating components to the cylindrical roller, avoiding the lubrication interruption problem caused by untimely or uneven addition of lubricating grease in traditional bearings. This provides long-term reliable lubrication protection for the bearing and effectively extends its service life.
[0012] 2. In this utility model, by providing a mounting base, an internal hex bolt B, and a threaded hole B, the dustproof mesh frame can be easily and conveniently fixed between the outer ring and the inner ring of the bearing; thereby effectively preventing external dust, impurities, etc. from entering the bearing; keeping the bearing clean, thus improving the bearing's operational reliability and service life.
[0013] 3. In this utility model, by providing auxiliary grooves on both sides of the pocket, the contact area between the lower cage and the cylindrical roller can be reduced, thereby reducing the friction between the lower cage and the cylindrical roller; thus optimizing the bearing's operating performance and reducing energy loss and wear.
