[0002] An air supply system is a system that delivers air to a specific space by mechanical or natural means. It is widely used in industrial production, building ventilation, equipment cooling and other scenarios. Its core function is to regulate air circulation and optimize environmental or process conditions. The wind turbine bearing is a key component of the air supply system. Its main function is to bear the weight of the wind turbine and the torque generated under the action of wind, and to reduce friction between relatively moving parts, so as to ensure that the wind turbine can rotate smoothly and efficiently.

[0003] Chinese Patent CN208221366U discloses a directional deep groove ball bearing, belonging to the field of bearing manufacturing technology. It solves the problems of easy wear and unstable performance in existing deep groove ball bearings.

An annular channel exists between the inner and outer rings, and a cage and steel balls are arranged within the annular channel. The cage includes a front cage and a rear cage fixedly connected to the front cage. Both the front and rear cages include a cage band and arc grooves. The arc grooves are uniformly circumferentially surrounding the cage band and protrude outwards. The arc grooves on the front and rear cages correspond one-to-one to form ball pockets for placing the steel balls. A directional lip is provided between every two adjacent arc grooves. The directional lip protrudes outwards radially along the inner ring. A guide groove for inserting the directional lip is provided on the inner end face of the outer ring. This invention has the advantages of long service life and stable operation.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0030] Please see Figures 1-7 The present invention provides the following technical solution:

[0031] A dustproof and sealed fan bearing for an air supply system includes: an outer ring 1, an inner ring 2, a cage 3, first balls 4, a dust cover 5, a connecting sleeve 6, a first sealing gasket 7, a second sealing gasket 8, a third sealing gasket 9, a second ball 10, a third ball 11, a heat dissipation hole 12, a guide hole 13, and a heat dissipation groove 14. The outer ring 1 is nested within the inner ring 2, and the outer ring 1 and the inner ring 2 are nested within the cage 3. The cage 3 contains centrally symmetrically arranged first balls 4, whose inner and outer sides respectively fit against the inner ring 2 and the outer ring 1. A dustproof sealing structure is provided outside the outer ring 1 and the inner ring 2. The lower outer end of the outer ring 1 has centrally symmetrically arranged heat dissipation holes 12. The dustproof sealing structure includes a dust cover 5, a connecting sleeve 6, a first sealing gasket 7, a second sealing gasket 8, and a third sealing gasket 9. The dust cover 5 is fitted onto the outer ring 1 and the cage 3.

[0032] The outer ring 1, inner ring 2, and cage 3 of the bearing have the same center. The inner diameter of the inner ring 2 is smaller than the lower inner diameter of the outer ring 1. A connecting sleeve 6, which is threaded to the outer ring 1, is fixedly connected to the lower outer end of the dust cover 5. The first sealing gasket 7 is pasted and fixed to the upper inner end of the outer ring 1. The second sealing gasket 8 and the third sealing gasket 9 are pasted and fixed to the inner and outer sides of the lower end of the dust cover 5, respectively. The first sealing gasket 7 and the second sealing gasket 8 are tightly fitted to the lower and upper inner surfaces of the inner end of the inner ring 2, respectively, and the third sealing gasket 9 is tightly fitted to the inner end of the outer ring 2. The outer end of the bearing outer ring 1 is provided with a second ball bearing 10 and a third ball bearing 11 that are centrally symmetrically connected to the inner side of the bearing outer ring 1 and the dust cover 5. The second ball bearing 10 and the third ball bearing 11 are located outside the first sealing gasket 7 and the second sealing gasket 8, respectively. The second ball bearing 10 and the third ball bearing 11 are respectively attached to the lower and upper surfaces of the outer end of the bearing inner ring 2. The upper and lower ends of the retainer 3 are provided with centrally symmetrically arranged guide holes 13. The upper end of the dust cover 5 is provided with a heat dissipation groove 14, which is located above the retainer 3.

[0033] When using impeller bearings in air supply systems with dustproof seals, such as Figure 1 , Figure 2 , Figure 4 and Figure 6 First, the operator can nest the cage 3 inside the outer ring 1 of the bearing. Then, the first ball 4 can be symmetrically snapped into the cage 3, so that the outer end of the first ball 4 is in contact with the outer ring 1 of the bearing. Next, the inner ring 2 of the bearing can be nested inside the outer ring 1 of the bearing, so that the inner end of the first ball 4 is in contact with the inner ring 2 of the bearing. Lubricating coolant can be poured into the outer ring 1 and the inner ring 2 of the bearing. Finally, the dust cover 5 can be moved above the outer ring 1, the inner ring 2 of the bearing and the cage 3, and the dust cover 5 can be rotated so that the connecting sleeve 6 fixedly connected to the lower side of the outer end of the dust cover 5 is threaded into the outer ring 1 of the bearing, until the dust cover 5 is in contact with the outer ring 1 and the cage 3, thus facilitating the quick assembly of the wind turbine bearing.

[0034] like Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 7During the use of this wind turbine bearing, the first ball 4, which is attached to the outer ring 1 and the inner ring 2 of the bearing, is fastened in the cage 3. An oil reservoir is formed in the outer ring 1, the inner ring 2 and the dust cover 5. The inner end of the outer ring 1 is symmetrically fastened with the second ball 10, which is attached to the inner ring 2. The inner end of the dust cover 5 is symmetrically fastened with the third ball 11, which is attached to the inner ring 2. This increases the lubrication space and ensures lubrication and anti-wear during the rotation of the inner ring 2. The upper and lower sides of the inner ring 2 are respectively tightly fitted with the second sealing gasket 8 and the first sealing gasket 7. The first sealing gasket 7 and the second sealing gasket 8 are respectively glued and fixed to the inner side of the outer ring 1 and the dust cover 5. The upper side of the outer end of the outer ring 1 is tightly fitted with the third sealing gasket 9, which is glued and fixed to the dust cover 5. This ensures the sealing performance between the outer ring 1, the inner ring 2 and the dust cover 5, thus ensuring the dustproof seal of the wind turbine bearing.

[0035] like Figure 2 , Figure 4 , Figure 5 and Figure 6 Furthermore, the bearing outer ring 1 has a centrally symmetrical heat dissipation hole 12 inside the lower outer end, and the retainer 3 has centrally symmetrical flow guide holes 13 inside both the upper and lower ends. The dust cover 5 has a heat dissipation groove 14 inside the upper end, located above the retainer 3. Therefore, it is easy to increase the heat dissipation area of ​​the wind turbine bearing, so that the heat dissipation effect is good, thereby making the wind turbine bearing have a long service life.
