Description
Technical field
The invention belongs to dustproof cover technical fields, and in particular to a kind of bearing dustproof cover.
Background technique
Bearing is a kind of widely used component of machine, whether aircraft, automobile, ship, lathe, motor or family
Electrical appliance etc., it is all to have the place rotationally supported, all it be unable to do without bearing.Bearing dustproof cover is a part of bearing, its master
Acting on is to prevent extraneous dust, impurity from entering Bearing inner, avoids the service performance for influencing bearing.
Bearing mainly includes inner ring, outer ring and roller between the two, and the use scope of bearing is very extensive at present, therefore
Often encounter the environment of bad environments, dust, which can enter in bearing, to be attached on roller, and bearing coefficient of friction itself is caused to increase
Greatly, serious to lead to bearing failure, this just needs that dust cover is arranged on bearing to be avoided dust from entering, dust-proof in the prior art
Structure is complicated for cover, and the scope of application is small.
Summary of the invention
The purpose of the present invention is to provide a kind of bearing dustproof covers, to solve the problems mentioned in the above background technology.
To achieve the above object, the invention provides the following technical scheme: a kind of bearing dustproof cover, including bearing outer ring and axis
Inner ring is held, dust excluding plate is fixedly installed between the bearing outer ring and bearing inner race, the dust excluding plate includes supporter, the branch
Be fixedly installed with dust guard on the outside of support body, the dust guard side is fixed with sponge hairbrush, the sponge hairbrush fit closely in
Bearing outer ring, the dust guard other end are fixedly installed with first support bar and second support bar, the first support bar and axis
It holds inner ring to be longitudinally bonded, the second support bar and bearing inner race transverse fit.
Preferably, foam-rubber cushion, the foam-rubber cushion side are fixedly installed between the first support bar and second support bar
It fits closely in bearing inner race.
Preferably, the supporting element is elastomer.
Preferably, magnet is fixedly installed on the outside of the first support bar and second support bar.
Preferably, it is fixedly installed with ball on the inside of the dust guard, the ball surface is fixedly installed with bearing cage.
Technical effect and advantage of the invention: the bearing dustproof cover is allowed to by being mounted with sponge hairbrush and magnet
First support bar and second support bar are closely fitted in bearing inner race surface by magnet, so that preventing in external environment
Moisture and other impurities can not enter Bearing inner, and in addition a small amount of moisture can be siphoned away by sponge hairbrush, improve
The drying property of Bearing inner environment, protection bearing is not damaged, improves in the service life and use process of bearing
Accuracy, by being mounted with supporting element, in addition the supporting element is elastomer, and the dust guard on the outside of supporting element is obtained
Support well, so that the better tightness of bearing.The bearing dustproof cover, which has, designs reasonable, structure novel, user
Just with good dustproof effect the advantages of while can be good at playing dust-proof effect, and can protect bearing without damage, improve
The precision of bearing and the service life for extending bearing.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention；
Fig. 2 is Fig. 1 anti-dust plate structure schematic diagram of the present invention.
In figure: 1 sponge hairbrush, 2 supporting elements, 3 first support bars, 4 second support bars, 5 bearing cages, 6 dust excluding plates, 7
Dust guard, 8 bearing inner races, 9 bearing outer rings, 10 balls, 11 foam-rubber cushions, 12 magnet.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Referring to Fig. 1, Fig. 1 is the structural diagram of the present invention；A kind of bearing dustproof cover, including bearing outer ring 9 and bearing
Inner ring 8, is fixedly installed with dust excluding plate 6 between the bearing outer ring 9 and bearing inner race 8, the dust excluding plate 6 includes supporter 2, institute
Stating supporting element 2 is elastomer, and the effect of the supporting element 2 is that the dust guard 7 in 2 outside of supporting element is propped up well
Support is fixedly installed with dust guard 7,7 side of dust guard on the outside of the supporter 2 so that the better tightness of bearing
Be fixed with sponge hairbrush 1, the effect of the sponge hairbrush 1 be prevent prevent moisture in external environment and other impurities from
Bearing inner is enough entered, a small amount of moisture can be siphoned away by sponge hairbrush 1, the drying property of Bearing inner environment is improved,
It protects bearing not damaged, improves the accuracy in the service life and use process of bearing, the sponge hairbrush 1 is close
Fitting in bearing outer ring 9,7 other end of dust guard is fixedly installed with first support bar 3 and second support bar 4, and described first
Support rod 3 is bonded with 8 longitudinal direction of bearing inner race, the second support bar 4 and 8 transverse fit of bearing inner race, the first support bar 3
