Abstract
The utility model provides a kind of anti-semi-enclosed taper roll bearing of foreign matter.Including a bearing inner race, a bearing outer ring and taper roller between the two is assemblied in, the height of described bearing inner race is more than the height of bearing outer ring, and a step is formed in the junction of bearing inner race and bearing outer ring；Dust guard is installed, dust guard is that some pieces of demountable panels are put together, and wraps the upper surface of whole step and bearing inner race, and concordant with the inner wall edge of bearing inner race at described step；Gap is provided between described dust guard and the upper surface of bearing inner race, gluey lubricating oil is filled with gap.The utility model is simple in construction, on the basis of existing bearing arrangement is not changed, can prevent from corroding, reduce the frictional resistance of bearing, reduce the abrasion of bearing, improve bearing life to being sealed between the outer ring of bearing and taper roller.
Description
Technical field
Bearing parts technical field is the utility model is related to, is related specifically to a kind of semi-enclosed taper roller axle of anti-foreign matter
Hold.
Background technology
Bearing is a kind of important spare part in contemporary plant equipment.Its major function is the mechanical rotary body of support, is reduced
Coefficient of friction in its motion process, and ensure its rotating accuracy.
By the difference of motor element frictional property, bearing can be divided into rolling bearing and the major class of sliding bearing two.Wherein roll
Bearing is normalized, seriation, but its radial dimension, vibration and noise are larger compared with sliding bearing, and price is also higher.
Rolling bearing is typically made up of outer ring, inner ring, rolling element and the part of retainer four, is strictly speaking by outer ring, inner ring, rolling
Body, retainer, sealing, six big part of lubricating oil composition.In simple terms, as long as possessing outer ring, inner ring, rolling element just may be defined as
Rolling bearing.By the shape of rolling element, rolling bearing is divided into ball bearing and the major class of roller bearing two.
At present, the bearing both ends of the surface that in the market is produced respectively are provided with a sealing ring；Sealing lip and high speed temperature of inner ring during rotation
Upper seal groove contact is easily worn.Bearing use external environment condition on grass-mowing machine, harvester is severe, and dust, moisture, foreign matter etc. have
Evil material constantly invades Bearing inner.Dust, moisture, foreign matter cause to make lubricating grease form greasy filth in bearing, greatly reduce axle
The greasy property held, reduce bearing service life；It is more severe especially for some work condition environments, and bearing needs to seal profit
Sliding good occasion, existing bearing can not meet requirement.
The content of the invention
Technical problem to be solved in the utility model is the defects of overcoming prior art, there is provided a kind of simple in construction, energy
It is enough effectively to prevent the harmful substances such as external dust, moisture, foreign matter from invading Bearing inner, the abrasion of bearing is reduced, improves the bearing longevity
The semi-enclosed taper roll bearing of anti-foreign matter of life.
To achieve these goals, the utility model uses following technical scheme：
The anti-semi-enclosed taper roll bearing of foreign matter, including a bearing inner race, a bearing outer ring and it is assemblied in two
Taper roller between person, it is characterised in that：The height of described bearing inner race is more than the height of bearing outer ring, in bearing inner race
A step is formed with the junction of bearing outer ring；Dust guard is installed, dust guard can for some pieces at described step
Stripper is put together, and wraps the upper surface of whole step and bearing inner race, and concordant with the inner wall edge of bearing inner race；Institute
Gap is provided between the dust guard stated and the upper surface of bearing inner race, gluey lubricating oil is filled with gap.
In such scheme, described dust guard includes two boards and is put together, respectively cover plate and baffle plate, wherein
Cover plate covers the surface of bearing outer ring, baffle plate is wrapped at stepped locations and bearing inner race upper surface.
In such scheme, in described dust guard, cover plate and baffle plate are connected structure, and groove is provided with baffle plate,
Cover plate enters in groove provided with raised grafting.
The utility model is by adopting the above-described technical solution, have the advantages that：
It is simple in construction, it can effectively prevent the harmful substances such as external dust, moisture, foreign matter from invading Bearing inner, reduce axle
The abrasion held, improve bearing life.
Brief description of the drawings
Fig. 1 is the overall structure figure of the utility model embodiment；
In figure：1-bearing inner race, 2-bearing outer ring, 3-taper roller, 4-cover plate, 5-baffle plate.
Embodiment
In order that content of the present utility model is readily apparent understood, below according to specific embodiment and combine attached
Figure, is described in further detail to the utility model.
As shown in figure 1, the anti-semi-enclosed taper roll bearing of foreign matter, including 1, bearing outer ring 2 of a bearing inner race,
And taper roller 3 between the two is assemblied in, the height of described bearing inner race 1 is more than the height of bearing outer ring 2, in bearing
The junction of inner ring 1 and bearing outer ring 2 forms a step；Dust guard is installed, dust guard includes at described step
There are two boards to be put together, respectively cover plate 4 and baffle plate 5, its cover plate 4 covers the surface of bearing outer ring 2, baffle plate 5 wraps
At the stepped locations and upper surface of bearing inner race 1, and it is concordant with the inner wall edge of bearing inner race 2；Described dust guard and bearing
Gap is provided between the upper surface of inner ring 1, gluey lubricating oil is filled with gap.
In the present embodiment, in described dust guard, cover plate 4 and baffle plate 5 are connected structure, are provided with baffle plate 5 recessed
Groove, cover plate 4 enter in groove provided with raised grafting.
Particular embodiments described above, technical problem, technical scheme and the beneficial effect solved to the utility model are entered
Further description is gone, should be understood that and the foregoing is only specific embodiment of the utility model, and do not have to
In limitation the utility model, all within the spirit and principles of the utility model, any modification, equivalent substitution and improvements done
Deng should be included within the scope of protection of the utility model.
