Background
Rotating equipment is equipment commonly used by industrial enterprises, and as a key component-bearing of the rotating equipment, the rotating equipment is a key factor for ensuring the normal and reliable operation of the rotating equipment. When the bearing rotates continuously at high speed, local thermal deformation can be generated due to friction, so that the abrasion of the surface of the accelerated part causes the increase of running errors, and the scrapping of the rotating shaft occurs. Therefore, in order to ensure safe and reliable operation of the bearing and avoid failure caused by pitting corrosion on the surface of the bearing, the bearing needs to be lubricated, and good lubrication can obviously improve the fatigue life, friction, abrasion, temperature, vibration and the like of the bearing, and analysis of the reasons of bearing damage shows that about 40% of bearing damage is related to poor lubrication.
Because the lubricating grease does not need a special oil supply system, the lubricating grease has the functions of reducing friction and accelerating cooling, has the advantages of simple sealing device, low maintenance cost, lower cost and the like, is widely used in bearings, and 80% of rolling bearings in the domestic mechanical industry are lubricated by the lubricating grease. However, in practical applications, when the bearing is running at a high speed, the rolling elements and the cage also rotate at a relatively high rotational speed, so that air vortex is formed around the bearing, so that a large amount of grease in the bearing is thrown into the cavity 32 of the bearing end cover, and accumulated grease 7 (shown in fig. 1 in detail) is formed due to poor flowability of the grease, and cannot participate in lubrication, so that the lubrication efficiency of the bearing is reduced, and the accumulated grease for a long time is hardened and consolidated to prevent the bearing from rotating normally, and is treated as waste grease during each maintenance, so that the waste of grease resources is also caused. In addition, in order to meet the thermal expansion requirement of the bearing during high-speed operation, a certain cavity must be reserved on the inner side part of the bearing end cover, so that the problem of grease accumulation between the bearing end cover and the bearing cannot be solved effectively.

Detailed Description
The technical scheme of the invention is further described in detail below with reference to the accompanying drawings and the examples.
Examples
Please refer to fig. 2 to 7: the rotating assembly capable of realizing self-circulation of lubricating grease comprises a rotating shaft 1, a bearing 2, a bearing end cover 3, a magnetic ring 4, a magnetism isolating sleeve 5 and an alicyclic guide ring 6, wherein the magnetic ring 4 is in interference connection with the rotating shaft 1 between the bearing 2 and the bearing end cover 3, one end of the magnetism isolating sleeve 5 is fixed at the inner bottom of the bearing end cover 3 (in the embodiment, a groove 31 is formed in the bottom surface of the inner side part of the bearing end cover 3, one end of the magnetism isolating sleeve is fixed in the groove 31), the alicyclic guide ring 6 is sleeved outside the magnetism isolating sleeve 5 and is in sliding connection with the magnetism isolating sleeve 5, and the magnetic ring 4 is positioned in the magnetism isolating sleeve 5 and is in clearance connection with the magnetism isolating sleeve 5; at least one magnet bar 41 is fixedly arranged on the outer peripheral side of the magnetic ring 4, at least one magnetic conduction hole 51 is formed on the outer peripheral side of the magnetism isolating sleeve 5, the fat guiding ring 6 is a circular ring made of magnetic conduction materials, and at least one fin 61 is fixedly arranged on the outer peripheral side of the circular ring.
Because the magnetic ring 4 is in interference connection with the rotating shaft 1, when the rotating shaft rotates, the magnetic ring 4 synchronously moves, in addition, because the magnetic ring 4 is positioned in the magnetism isolating sleeve 5, and the magnetism conducting holes 51 are formed in the periphery side of the magnetism isolating sleeve 5, when the magnetic ring 4 rotates until the magnet strips 41 correspond to the magnetism conducting holes 51, the magnetic force of the magnet strips 41 passes through the magnetism conducting holes 51 to be projected onto the grease conducting ring 6 made of magnetism conducting material, and the grease conducting ring 6 rotates under the action of the magnetic force, so that the lubricating grease thrown into the cavity 32 of the bearing end cover is scraped in time through the fins 61 on the grease conducting ring 6 and is led into the bearing; because the relative movement of the magnet bar 41 and the magnetic conduction hole 51 is intermittently realized, the generated magnetic force action is also intermittent, so that the grease guide ring can generate stepping movement, and further, the grease thrown into the cavity 32 of the bearing end cover can be ensured to be completely led into the bearing, and the problem of grease accumulation can not be generated. The stepping movement speed of the alicyclic ring 6 can be adjusted by the number and the size of the magnet bars 41 and the magnetic holes 51.
As a preferable scheme:
the magnetic ring 4 is a circular ring made of reinforced plastic, so that the load on the rotating shaft 1 is reduced as much as possible, and the influence on the rotating speed of the rotating shaft 1 is avoided; the magnetism isolating sleeve 5 is a ring made of stainless steel so as to achieve a better magnetism isolating effect.
The fins 61 are wedge-shaped, and the two side surfaces are inward concave cambered surfaces 611, so as to play a better role in scraping and guiding fat.
The width of the non-fixed part of the magnetism isolating sleeve and the width of the grease guide ring 6 are matched with the width of the cavity 32 of the bearing end cover, so that the fins 61 on the grease guide ring 6 can effectively scrape lubricating grease in the cavity 32 of the bearing end cover.
In summary, according to the rotating assembly provided by the invention, the magnetic ring 4, the magnetism isolating sleeve 5 and the grease guide ring 6 are skillfully added, and the intermittent magnetic force is utilized to enable the grease guide ring 6 to perform intermittent rotating motion, so that grease thrown into the cavity 32 of the bearing end cover can be timely guided into the bearing 2, not only can the grease accumulation be effectively avoided, but also the amount of grease participating in the lubricating action is increased, so that the lubricating efficiency is obviously improved, the energy consumption is saved, the service life of the rotating assembly is prolonged, the working stability of the rotating equipment is ensured, the requirements of energy conservation, environmental protection and safety production are obviously met, and the rotating assembly can be widely applied to various places with the rotating equipment.
