Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of dust cover of bearing.
Background technique
Bearing is in mechanical transmission course, play parts that are fixing and reduction load friction factor.Alternatively, when other parts produce relative movement each other on axle, be used for reducing the fixing parts of friction factor in power transmission process and retainer shaft central position.Bearing is a kind of very important component in contemporary machinery.Its major function is supported mechanical solid of rotation, in order to reduce the mechanical load friction factor of equipment in transmission process.By the difference of motor element frictional property, bearing can be divided into rolling bearing and sliding bearing two class.
Bearing mainly comprises inner ring, outer ring and roller between the two; the using scope of current bearing widely; therefore the environment of bad environments can often be encountered; dust can enter in bearing and be attached on roller; cause the friction factor of bearing own to increase, serious causes bearing failure, and this just needs on bearing, arrange dust-proof cover and enters to be avoided dust; the complex structure of dust-proof cover in prior art, Applicable scope is little.
Summary of the invention
The purpose of this utility model there are the problems referred to above for existing technology, proposes a kind of dust cover of bearing, and the technical problem that the utility model solves to prevent dust from entering bearing.
The purpose of this utility model realizes by following technical proposal:
A kind of dust cover of bearing, it is characterized in that, comprise dust cover, Ring like suction disc and annular sponge, the middle part of described dust cover has through hole, described Ring like suction disc and annular sponge are fixed on the same side of dust cover, described Ring like suction disc comprises annular base portion and sucking disk part, and described annular base portion is fixed on the side of dust cover near outside, and the side that described annular sponge is fixed on dust cover is located near inner side.
The diameter of dust cover is suitable with the diameter of bearing, and the diameter of through hole is identical with the intermediate hole diameter of bearing; Ring like suction disc is adsorbed on the side of bearing outer ring, annular sponge is resisted against on the side of bearing inner race, annular sponge is adsorbed with lubricant oil, this structure, by the space-closed between bearing outer ring and inner ring, prevents entering of dust, and the outer ring of dust cover and bearing is located, with the inner ring energy relative movement of bearing, can not affect the normal operation of bearing, this dust cover structure is simple, applied widely.
In the dust cover of above-mentioned bearing, described annular sponge comprises circular base and sponge, and the side of dust cover has annular fixed groove near inner side place, and above-mentioned circular base is positioned in annular fixed groove.This structure makes annular sponge replaceable, increases the working life of dust cover.
In the dust cover of above-mentioned bearing, in the middle part of the side of described dust cover, have annular groove.This structure can alleviate the weight of dust cover.
In the dust cover of above-mentioned bearing, the side of described dust cover is fixed with some magnet, magnet circumference is evenly distributed on dust cover, and magnet is between Ring like suction disc and annular groove.The outer ring that magnet can be adsorbed on bearing is played the effect of auxiliary positioning, prevent the relative bearing displacement of dust cover.
In the dust cover of above-mentioned bearing, described dust cover is adopted made of plastic.Ring like suction disc and dust cover are fixed by hot melt.
Compared with prior art, the dust cover of this bearing has the advantage that can prevent dust from entering bearing.
Accompanying drawing explanation
Fig. 1 is the dust cover using state cross-sectional schematic of this bearing.
In figure, 1, dust cover; 11, through hole; 12, annular groove; 2, Ring like suction disc; 21, annular base portion; 22, sucking disk part; 3, annular sponge; 31, circular base; 32, sponge; 4, magnet; 51, outer ring; 52, inner ring.
Embodiment
Be below specific embodiment of the utility model and by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
As shown in Figure 1, the dust cover of bearing, comprises dust cover 1, Ring like suction disc 2 and annular sponge 3, and the middle part of dust cover 1 has through hole 11, has annular groove 12 in the middle part of the side of dust cover 1.
As shown in Figure 1, Ring like suction disc 2 and annular sponge 3 are fixed on the same side of dust cover 1, Ring like suction disc 2 comprises annular base portion 21 and sucking disk part 22, dust cover 1 is adopted made of plastic, annular base portion 21 is fixed on the side of dust cover 1 near outside by hot melt, and the side that annular sponge 3 is fixed on dust cover 1 is located near inner side.
As shown in Figure 1, annular sponge 3 comprises circular base 31 and sponge 32, and the side of dust cover 1 has annular fixed groove near inner side place, and above-mentioned circular base 31 is positioned in annular fixed groove.This structure makes annular sponge 3 replaceable, increases the working life of dust cover 1.
As shown in Figure 1, the side of dust cover 1 is fixed with some magnet 4, magnet 4 circumference is evenly distributed on dust cover 1, and magnet 4 is between Ring like suction disc 2 and annular groove 12.The outer ring 51 that magnet 4 can be adsorbed on bearing is played the effect of auxiliary positioning, prevent dust cover 1 bearing displacement relatively.
The diameter of dust cover 1 is suitable with the diameter of bearing, and the diameter of through hole 11 is identical with the intermediate hole diameter of bearing; Ring like suction disc 2 is adsorbed on the side of bearing outer ring 51, annular sponge 3 is resisted against on the side of bearing inner race 52, annular sponge 3 is adsorbed with lubricant oil, this structure is by the space-closed between bearing outer ring 51 and inner ring 52, prevent entering of dust, dust cover 1 is located with the outer ring 51 of bearing, and the inner ring 52 energy relative movement with bearing, can not affect the normal operation of bearing.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various amendment or supplements or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present utility model or surmount the scope that appended claims defines.
