Description
Technical field
The utility model is related to technical field of bearings, is related specifically to a kind of anti-infiltration type sealed bearings.
Background technology
Bearing is a kind of important spare part in contemporary plant equipment.Its major function is the mechanical rotary body of support, reduction
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, the big part of lubricating oil six composition.In simple terms, just it may be defined as long as possessing outer ring, inner ring, rolling element
Rolling bearing.By the shape of rolling element, rolling bearing is divided into ball bearing and the major class of roller bearing two.
The oil sealing that present bearing is used all is three-layer sealed bead structure, less demanding or no connect in use environment
During continuous rainy day ponding situation, bearing seal performance is it cannot be guaranteed that intact, and the sewage and impurity of outside penetrate into axle along sealing lip
Hold, cause deterioration of lubricant to lose greasy property, damage bearing.
The content of the invention
Technical problem to be solved in the utility model is to overcome the defect of prior art there is provided a kind of simple in construction, energy
Isolation sewage and fine particle, reliable and stable lubricant environment are improved to bearing, it is ensured that the clean and life-span of lubricating oil well
Anti- infiltration type sealed bearings.
To achieve these goals, the utility model uses following technical scheme：
A kind of anti-infiltration type sealed bearings, include bearing body, and bearing body includes the rolling of outer ring, inner ring and centre
Pearl, being wrapped with dust cap, dust cap for bearing body is provided with lubricant passage way, it is characterised in that described outer ring and inner ring
Between be also equipped with a sealing device, sealing device is annular, is close to the inwall of dust cap, by the sky between inner ring and outer ring
Chamber is sealed；The section of described sealing device is a rectangle, just to being provided with containment member and pressure at lubricant passage way position
Tight component；Wherein described containment member is the detachable rectangular block of an inner hollow, and rectangular block both sides are provided with scalable
Flexible sealing lip be used for seal；Described pressed component is arranged in the middle of rectangular block, and pressed component includes a torsion spring, is turned round
The two ends of spring connect the sealing lips of rectangular block both sides respectively, and there is provided thrust.
In such scheme, in the rectangle in the section of described sealing device, three faces are only included, concave character type shape is formed
Shape, the one side of opening covers realization sealing by dust cap.
In such scheme, described sealing device just to being additionally provided with oil inlet on a face of dust cap, for profit
Lubricating oil flows into inner ring.
The utility model is by adopting the above-described technical solution, have the advantages that：
The utility model is simple in construction, and sewage and fine particle can be isolated well, and reliable and stable profit is improved to bearing
Slip ring border, it is ensured that the clean and life-span of lubricating oil.
Brief description of the drawings
Fig. 1 is the overview of the utility model embodiment；
In figure：1 outer ring, 2 inner rings, 3 balls, 4 dust caps, 5 lubricant passage ways, 6 flexible sealing lips, 7 torsion springs, 8 rectangular blocks, 9
Oil inlet.
Embodiment
In order that content of the present utility model is readily apparent understood, below according to specific embodiment and with reference to attached
Figure, is described in further detail to the utility model.
Anti- infiltration type sealed bearings as shown in Figure 1, include bearing body, bearing body includes outer ring 1, the and of inner ring 2
Middle ball 3, being wrapped with dust cap 4, dust cap 4 for bearing body is provided with lubricant passage way 5, described outer ring 1 and interior
Be also equipped with a sealing device between circle 2, sealing device is annular, is close to the inwall of dust cap 4, by inner ring 2 and outer ring 1 it
Between cavity seal；The section of described sealing device is a rectangle, just to being provided with sealing structure at the position of lubricant passage way 5
Part and pressed component；Wherein described containment member is the detachable rectangular block 8 of an inner hollow, and rectangular block both sides are provided with
Retractable and flexible sealing lip is used to seal；Described pressed component is arranged in the middle of rectangular block, and pressed component includes one
Torsion spring, the two ends of torsion spring connect the sealing lips of rectangular block both sides respectively, and there is provided thrust.
In the present embodiment, in the rectangle in the section of described sealing device, three faces have been only included, concave character type shape is formed
Shape, the one side of opening covers realization sealing by dust cap 4.
In the present embodiment, described sealing device just to being additionally provided with oil inlet 9 on a face of dust cap 4, supply
Lubricating oil flows into inner ring 2.
Particular embodiments described above, enters to technical problem, technical scheme and the beneficial effect that the utility model is solved
Go further description, should be understood that and the foregoing is only specific embodiment of the utility model, and without
It is all within spirit of the present utility model and principle in limitation the utility model, any modification, equivalent substitution and improvements done
