Description
Technical Field
[0001] The utility model belongs to the technical field of bearing sealing and relates to a bearing dustproof protective cover. Background Art
[0002] Bearings are important parts of mechanical operation parts. They operate in some unclean environments, especially those with serious dust, mud, and rain. Dust and foreign matter entering the bearings may lead to early scrapping and shorten the life of the mechanical equipment, and may also easily cause mechanical accidents. Utility Model Content
[0003] The utility model aims to solve the above problems and provide a bearing dust protection cover.
[0004] To achieve the above purpose, the utility model provides a bearing dust protection cover, including a sealing cap connected to the bearing 1, the sealing cap includes a main body and bending parts symmetrically arranged at both ends of the main body, and the bending part is provided with a connecting end to cooperate with the bearing.
[0005] Furthermore, a dust cover slot is provided on the inner side of the bearing outer ring.
[0006] Furthermore, the connection ends on the two bending portions extend relatively obliquely in a direction away from the bending portion.
[0007] Furthermore, an escape portion is provided on the outer side of the bearing outer ring, and a second dustproof groove is provided on the outer side wall of the escape portion.
[0008] Furthermore, the connecting ends on the two bending portions extend obliquely towards each other.
[0009] Furthermore, a sealing cavity is provided between the sealing cap and the bearing.
[0010] The beneficial effects of the utility model are as follows:
[0011] The bearing dust protection cover of the utility model can achieve sealing for the bearing through the setting of the sealing cap, especially the setting of the bent portion, so that the sealing cap has a certain height, and the shaft matched with the bearing can also be sealed, thereby preventing dust from entering the bearing from the contact part between the inner ring of the bearing and the sealing ring of the shaft, achieving super strong sealing and improving the bearing life.

[0018] In order to more clearly illustrate the implementation of the utility model or the technical solution in the prior art, the drawings required for the implementation are briefly introduced below. Obviously, the drawings described below are only some implementations of the utility model. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work.
[0019] The present invention will be described in detail below in conjunction with the accompanying drawings and specific implementation methods. The implementation methods cannot be described one by one here, but the implementation methods of the present invention are not therefore limited to the following implementation methods.
[0020] The utility model provides a bearing dust protection cover, including a sealing cap 2 connected with a bearing 1. The sealing cap 2 of the utility model is configured to include a main body 21 and a bent portion 22, the bent portions 22 are symmetrically arranged at both ends of the main body 21, and the bent portion 22 is provided with a connecting end 23 to seal with the bearing 1. In this embodiment, the sealing cap 2 is a topic-shaped structure.
[0021] The bearing dust protection cover of the utility model can achieve sealing for the bearing 1 through the setting of the sealing cap 2, especially the setting of the bent portion 22, so that the sealing cap 2 has a certain height, and the shaft matched with the bearing can also be sealed, thereby preventing dust from entering the bearing 1 from the contact part between the inner ring of the bearing 1 and the sealing ring of the shaft, achieving super strong sealing and improving the bearing life.
[0022] The bearing dust protection cover of the utility model is described in detail with specific embodiments below.
[0023] Combination Figure 1 and Figure 2As shown, according to the first embodiment of the present invention, a dust cover slot 11 is provided on the inner side of the outer ring of the bearing 1. The connecting ends 23 on the two bent portions 22 of the sealing cap 2 extend relatively inclined in a direction away from the bent portions 22. Figure 2 As shown, the connection ends 23 extend outwardly in an inclined manner, and the connection ends 23 are sealed with the dust cover slot 11. In this embodiment, a sealing cavity 3 is provided between the sealing cap 2 and the bearing 1, and the shaft end is located in the sealing cavity 3 to achieve full surrounding sealing.
[0024] Combination Figure 3 and Figure 4 As shown, according to the second embodiment of the utility model, the outer side of the outer ring of the bearing 1 is provided with an escape portion 12, and the outer side wall of the escape portion 12 is provided with a second dustproof groove 13. In a specific application, the outer ring of the bearing 1 can be turned to remove a portion of the outer diameter to form the escape portion 12, and then the second dustproof groove 13 is provided. In this embodiment, the connection ends 23 on the two bent portions 22 extend obliquely toward each other. That is, Figure 4 As shown, the connection ends 23 are all extended inwardly obliquely. In this embodiment, a sealing cavity 3 is provided between the sealing cap 2 and the bearing 1, and the shaft end is located in the sealing cavity 3, so as to realize a fully enclosed sealing.
[0025] The bearing dust protection cover of the utility model does not change the bearing structure (the dust cover slot 11 is provided by the bearing itself) or only slightly changes the bearing structure, and uses the sealing cap 2 to achieve safe sealing, thereby reducing the loss cost of mechanical equipment, reducing equipment accidents, and enabling the bearing to work normally under dusty and muddy working conditions.
[0026] The above is only one embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
