The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art through specific situations.
Referring to fig. 1, a preferred embodiment of the present invention provides a waterproof bearing 100 for a motor of a wet and dry vacuum cleaner, comprising: the bearing comprises a bearing outer ring 1, a bearing inner ring 2, a retainer 3, a rolling body 4, a sealing ring 5 and a shielding cover 6. The retainer 3 is positioned between the bearing outer ring 1 and the bearing inner ring 2, and the rolling elements 4 are mounted on the retainer 3. It should be noted that the structures and functions of the cage 3 and the rolling elements 4 are prior art and are not described in detail herein.
Be equipped with outer seal groove 11 on the inner wall of bearing inner race 1, outer seal groove 11 is used for holding sealing washer 5 in order to increase bearing 100's leakproofness, avoids outside liquid to enter into bearing 100 in, leads to the inside rust of bearing 100. To further avoid rusting inside the bearing 100, in one embodiment, the material of the bearing outer ring 1 is provided as a stainless steel material. The shape of the outer seal groove 11 is not exclusive and may be provided in a regular shape, for example, a V-groove or a T-groove. Of course, in order to further improve the sealing performance of the bearing 100, the outer seal groove 11 may be provided as a complex irregular groove, so that the length of an outer seal pair (not numbered) formed by the seal ring 5 and the outer seal groove 11 is as long as possible.
The bearing inner ring 2 is positioned in the bearing outer ring 1 and is coaxially arranged with the bearing outer ring 1. An inner sealing groove 21 is formed in the outer wall of the bearing inner ring 2, and the inner sealing groove 21 is also used for accommodating the sealing ring 5 to improve the sealing performance of the bearing 100, so that external liquid is prevented from entering the bearing 100 and rusting inside the bearing 100 is avoided. To further avoid rust formation inside the bearing 100, in one embodiment, the material of the bearing inner race 2 is also provided as a stainless steel material. The shape of the inner seal groove 21 is not exclusive and may be provided in a regular shape, for example, a V-groove or a T-groove. Of course, in order to further improve the sealing performance of the bearing 100, the inner seal groove 21 may be provided as a complex irregular groove, so that the length of an inner seal pair (not numbered) formed by the seal ring 5 and the inner seal groove 21 is as long as possible.
Since the bearing 100 is sleeved outside a rotating shaft (not shown) of the vacuum cleaner, when the rotating shaft rotates, the bearing inner ring 2 rotates along with the rotating shaft, and if the seal ring 5 and the bearing inner ring 2 are in a mutually abutting state, heat is generated due to long-time friction between the bearing inner ring 2 and the seal ring 5 in the rotating process of the bearing inner ring 2, so that the internal temperature of the bearing 100 is too high, and the service life of the bearing 100 is affected. In order to solve the above problem, in one embodiment, the seal ring 5 is disposed such that one end abuts against the outer seal groove 11 and the other end is clearance-fitted to the inner seal groove 21. With the arrangement, when the bearing inner ring 2 rotates, the outer surface of the bearing inner ring 2 is in a non-smooth uneven shape, so that surrounding gas can be driven to rotate to form an approximately closed air ring, and external liquid cannot enter the bearing 100 through the air ring, so that the problem of friction heating between the sealing ring 5 and the bearing inner ring 2 is solved, and the sealing performance inside the bearing 100 is improved. Further, since the seal ring 5 and the bearing inner ring 2 are in a non-contact state, the bearing inner ring 2 does not reduce the rotation speed of the bearing 100 due to friction with the seal ring 5.
Optionally, the sealing ring 5 is interference fit with the outer sealing groove 11. With this arrangement, the sealing performance of the bearing 100 is further improved.
In the present embodiment, the seal ring 5 has one, and is located on one side of the bearing outer ring 1. At this moment, in order to make bearing 100 both sides all have the leakproofness, wet or dry dust catcher motor bearing 100 still includes shield 7, and shield 7 is located the opposite side of bearing inner race 1, sets up with sealing washer 5 is relative, has guaranteed that bearing 100 both sides all can not let outside liquid get into.
Of course, in other embodiments, there may be two sealing rings 5, and two sealing rings 5 are respectively located on two sides of the bearing outer ring 1. In this case, a dust cap 7 may be provided outside the seal ring 5, thereby further improving the sealing performance of the bearing 100. Optionally, the clearance between the dust cap 7 and the sealing ring 5 is 0.05mm-0.1 mm.
The shielding cover 6 is located between the holder 3 and the seal ring 5. When part of the external liquid passes through the sealing ring 5 and enters the bearing 100, the shielding cover 6, the bearing outer ring 1 and the bearing inner ring 2 are arranged in an enclosing manner to form a closed space, and the shielding cover 6 is used for further shielding the external liquid, so that the sealing performance in the bearing 100 is further improved.
If external fluid has entered the bearing 100, the degree of rust in the bearing 100 can be reduced by providing the ball bodies 4 with a stainless steel material or a ceramic material and the retainer 3 with a glass fiber reinforced nylon retainer in order to reduce the degree of rust in the bearing 100.
In conclusion, the embodiment provides the waterproof bearing for the motor of the dust collector for both dry and wet use, the sealing ring is arranged between the bearing outer ring and the bearing inner ring, so that the sealing property in the bearing can be improved, and the bearing is prevented from rusting due to the fact that liquid enters the bearing; in addition, one end of the sealing ring is abutted against the outer sealing groove, and the other end of the sealing ring is in clearance fit with the inner sealing groove, so that the problem of friction heating caused by contact between the traditional bearing inner ring and the sealing ring can be solved; in addition, the shielding cover is arranged between the holding frame and the sealing ring, so that the shielding cover, the bearing outer ring and the bearing inner ring are surrounded to form a closed space, liquid is further prevented from entering the bearing, and the sealing performance inside the bearing is improved.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the utility model. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
