Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0036] Embodiment one

[0037] Referring to Figures 1-4 A bearing sleeve with high oil injection rate, comprising a main component 1, the main component 1 comprises: an outer ring 11, the inner side of which is provided with an inner ring 12; a partition plate 13 fixedly connected between the outer ring 11 and the inner ring 12; an oil storage cavity 14 opened at the top of the partition plate 13; the main component 1 is provided with an oil injection assembly 2, the oil injection assembly 2 comprises: an air bag 21 arranged at the top of the partition plate 13; a micro air pump 211 arranged in the cavity at the bottom of the partition plate 13, the top output end of the micro air pump 211 penetrates the partition plate 13 and is connected with the air bag 21, the bottom input end of the micro air pump 211 penetrates and extends to the bottom of the outer ring 11; a bottom plate 22 fixedly connected at the top of the air bag 21, the bottom plate 22 is slidingly connected inside the oil storage cavity 14; an oil absorption sponge 23 arranged at the top of the bottom plate 22; a cavity 24 opened inside the inner ring 12; a channel 25 opened on the inner ring 12, the channel 25 connects the oil storage cavity 14 and the cavity 24; an oil injection port 26 opened on the inner wall of the inner ring 12, the oil injection port 26 is connected with the cavity 24. Multiple groups of the cavity 24, the channel 25 and the oil injection port 26 are circumferentially symmetrically arranged, and multiple places of the oil injection port 26 are symmetrically arranged upward and downward. An oil hole 27 is opened at the top of the outer ring 11, and a sealing plug 271 is arranged in the oil hole 27.

[0038] When the bearing rolling body needs to be lubricated, the staff starts the micro air pump 211, the micro air pump 211 transports the air outside the outer ring 11 into the air bag 21, the air bag 21 lifts the bottom plate 22 upward in the process of inflation, the bottom plate 22 is gradually compressed when rising, the lubricating oil soaked in the oil absorption sponge 23 is gradually squeezed out, the lubricating oil flows into the cavity 24 through the inclined channel 25, and is discharged from the inner ring 12 through the oil injection port 26 penetrating the cavity 24, realizing the lubrication effect of the rolling body in the middle of the inner ring 12, the staff changes the inflation degree of the air bag 21 to control the compression degree of the oil absorption sponge 23, so as to realize the quantitative discharge of the lubricating oil, which is convenient for different working scenes.

[0039] When the lubricating oil in the oil absorption sponge 23 is almost used up, the staff pulls out the sealing plug 271, injects lubricating oil into the oil storage cavity 14 through the oil hole 27, so that the lubricating oil is soaked in the oil absorption sponge 23 again, which is convenient for next use.

[0040] The plurality of groups of cavities 24, channels 25 and oil injection ports 26 increase the oil injection area, thereby improving the uniformity and efficiency of oil injection.

[0041] The above micro air pump 211 drives the piston to do reciprocating motion in the cylinder by motor, absorbs and compresses air and then outputs. Its structure is relatively simple, can be designed very small according to the demand, can provide a certain pressure of compressed air in small space, such as some 12V micro air pump vacuum pump.

[0042] Example two

[0043] According to the basis of example one, the auxiliary function is increased.

[0044] Referring to Figures 1-4 , the filter screen 3 is fixedly connected to the inner side wall of the oil storage cavity 14, and the filter screen 3 is located above the oil absorption sponge 23. The micro air pump 211 is circumferentially symmetrically provided with multiple places, and at least two places are provided. The lubricating groove 4 is symmetrically opened in the inner side wall of the inner ring 12.

[0045] The filter screen 3 limits the oil absorption sponge 23, when the air bag 21 is inflated to lift the oil absorption sponge 23 upward, the oil absorption sponge 23 contacts the filter screen 3 and then extrudes the internal lubricating oil, the filter screen 3 limits the activity space of the oil absorption sponge 23, so that when the air bag 21 is deflated and the bottom plate 22 moves downward, the oil absorption sponge 23 can quickly rebound to the original state, avoiding affecting the compression effect of the bottom plate 22 on the oil absorption sponge 23 next time. The micro air pump 211 arranged at multiple positions realizes that the air bag 21 at the bottom is provided with multiple inflation ports for inflation, thereby improving the uniformity of inflation of the air bag 21 at each position, so that the extrusion of the bottom plate 22 on the oil absorption sponge 23 is more stable, and the uniformity of oil outlet of each oil injection port 26 is facilitated. After the oil injection port 26 is out of oil, the lubricating groove 4 on the inner side of the inner ring 12 can make the lubricating oil more evenly distributed on the contact surface of the inner ring 12 and the rolling body, thereby improving the lubricating effect. Moreover, the lubricating groove 4 can store lubricating oil, improve the lubricating condition, and also improve the surface load capacity and anti-wear performance.

[0046] Although the embodiments of the present application have been shown and described, it should be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
