Description

Dustproof bearing based on active carbon

Technical Field

The invention relates to the field of bearing correlation, in particular to a dustproof bearing based on activated carbon.

Background

The bearing is an important part in the modern mechanical equipment, and has the main functions of supporting the mechanical rotating body, reducing the friction coefficient in the movement process of the mechanical rotating body and ensuring the rotation precision of the mechanical rotating body;

the dustproof of bearing is one of the difficult problems in the bearing use, because the pivoted characteristic of bearing, always can reserve the clearance on its seal structure, otherwise will influence the normal rotation of bearing, and this has just led to the entering of dust, therefore dustproof and the rotation of bearing have certain conflict, and present bearing dustproof construction also has the clearance mostly, therefore dustproof effect is bad minds.

Disclosure of Invention

In order to overcome the defects in the prior art, the invention provides the dustproof bearing based on the activated carbon, and the dust entering the bearing can be adsorbed and cleaned through the adsorption effect of the activated carbon, so that the effective dustproof effect is achieved.

Technical scheme

A dustproof bearing based on activated carbon comprises a rotating shaft and a bearing, wherein two sides of the bearing are fixedly provided with a connecting cover shell, the connecting cover shell is provided with a first through hole, the rotating shaft penetrates through the first through hole and is not contacted with the connecting cover shell, a side surface of the connecting cover shell, which is far away from the bearing, is provided with a first splicing groove, the rotating shaft is also fixedly connected with two fixed sleeves with symmetrical positions, the fixed sleeves are detachably and fixedly provided with a plurality of blocking disks, the surfaces of the blocking disks are provided with an activated carbon layer for dust removal, the connecting cover shell is also provided with a protective cover mechanism, the number of the protective cover mechanism corresponds to that of the blocking disks, the protective cover mechanism comprises a connecting ring which is tightly connected with the first splicing groove, one end of the connecting ring, which is far away from the connecting cover shell, is fixedly provided with a protective cover, and a second splicing groove is formed in one side face, far away from the connecting housing, of the protection cover, and a second through hole which can be penetrated through by the rotating shaft is further formed in the protection cover.

Furthermore, the safety cover with contactless just leave little passageway between the activated carbon layer, the existence of little passageway makes the rotation of pivot is not influenced, just the activated carbon layer can with dust in the air in the little passageway adsorbs, thereby realizes the dustproof effect of bearing.

Further, the second splicing groove can be matched with and tightly connected with the connecting ring.

Furthermore, the number of the blocking disks and the number of the protective covers are two, and if the use environment is severe, the number of the blocking disks and the number of the protective covers can be increased.

Further, the fixing sleeve and the rotating shaft are subjected to sealing treatment.

Advantageous effects

Compared with the prior art, the invention has the following beneficial effects: because of the rotation of the bearing, the sealing structure of the bearing always has a gap, which also causes the dust to enter, and the dust entering the bearing can be absorbed and cleaned through the adsorption effect of the activated carbon, thereby achieving the effective dustproof effect.

fig. 2 is an enlarged view of a point a in fig. 1.

Reference numerals

The device comprises a rotating shaft 1, a bearing 2, a connecting cover 3, a fixed sleeve 4, a blocking disc 5, an activated carbon layer 6, a second through hole 7, a protective cover 8, a second splicing groove 9, a connecting ring 10, a first through hole 11, a first splicing groove 12 and a fine channel 13.

Detailed Description

For a better illustration of the invention, reference is made to the following description, taken in conjunction with the accompanying drawings and examples:

as shown in fig. 1-2, the invention discloses an active carbon-based dustproof bearing, which comprises a rotating shaft 1 and a bearing 2, wherein two sides of the bearing 2 are fixedly provided with a connecting cover 3, the connecting cover 3 is provided with a first through hole 11, the rotating shaft 1 penetrates through the first through hole 11 and is not contacted with the connecting cover 3, a first splicing groove 12 is arranged in the surface of one side of the connecting cover 3 far away from the bearing 2, the rotating shaft 1 is also fixedly connected with two fixed sleeves 4 with symmetrical positions, the fixed sleeves 4 are detachably and fixedly provided with a plurality of blocking disks 5, the surface of each blocking disk 5 is provided with a layer of active carbon layer 6 for dust removal, the connecting cover 3 is also provided with protective cover mechanisms with the number corresponding to the number of the blocking disks 5, the protective cover mechanisms comprise connecting rings 10 tightly connected with the first splicing grooves 12, the connecting ring 10 is far away from the fixed safety cover 8 that is provided with of one end of connecting housing 3, keeping away from of safety cover 8 be provided with second splice groove 9 in the side of connecting housing 3, still be provided with on the safety cover 8 can by the second perforation 7 that pivot 1 runs through.

Further, the safety cover 8 with contactless and leave the fine passageway 13 between the activated carbon layer 6, the existence of fine passageway 13 makes the rotation of pivot 1 is not influenced, just activated carbon layer 6 can with dust in the air in the fine passageway 13 adsorbs, thereby realizes the dustproof effect of bearing 2.
