Abstract
The utility model belongs to field of bearings, relates generally to a kind of sealed type roller bearing, comprises outer ring, inner ring, retainer, rolling element, back-up ring, filter screen circle, two seal rings, two spring rings.Back-up ring is established in inner ring side, and back-up ring is provided with extension skeleton, and extension skeleton and the second seal ring are bonded as one, and outer ring is close in the second seal ring outer; Outer ring and inner ring opposite side are provided with concave station, are provided with filter screen circle between inside and outside circle concave station, and filter screen circle is bolted on inner ring concave station, and filter screen circle outside diameter hoop silhouette edge is bonded with the first seal ring, and outer ring is close in the first seal ring outer.The utility model structure is simple, two end faces all effective sealings, and filter screen circle can intercept introduced contaminants, but lubricant oil can be allowed to penetrate into rolling element slideway.
Description
Technical field
The utility model relates to field of bearings, relates in particular to a kind of sealed type roller bearing.
Background technique
Now general roller bearing is made up of outer ring, inner ring, retainer, rolling element four major part, is often used to the High Rotation Speed occasion needing to bear radial load, thrust load.In running, lubrication and the sealing of bearing have material impact to bearing life, and sufficient lubrication can reduce surface friction drag, alleviates wearing and tearing.Although current open roller bearing can use, owing to lacking sealing, easily cause bleeding of lubricant, the impurity etc. simultaneously in extraneous foreign particles and lubricant oil easily enters bearing, causes bearing damage, reduces bearing working life.And the mode that the many employings of sealed type roller bearing conventional at present arrange seal ring between bearing outer ring and inner ring seals, this sealing configuration needs the seal groove of processing structure complexity on bearing enclose end face, and complicated operation, work efficiency is low.
Summary of the invention
For the deficiencies in the prior art, the utility model provides a kind of sealed type roller bearing that a kind of structure is simple, be easy to processing.
The technical solution adopted in the utility model is as follows:
A kind of sealed type roller bearing, comprises outer ring, inner ring, retainer, cylindrical roller, and cylindrical roller can roll or slide in the slideway of outer ring and inner ring, and retainer is separated into equal distance cylindrical roller, guarantees to roll and carries out smoothly.Outer ring and inner ring the same side are processed with circular groove respectively, use and hold filter screen circle and the first seal ring; The groove axial depth of outer ring is larger than the groove axial depth of inner ring, makes not swipe between filter screen circle and the outer ring rotated corresponding thereto; The groove of inner ring has been screwed filter screen circle, the material manufacture that can keep off dust, energy oil impregnate of filter screen circle, filter screen circle peripheral circumferential profiles is bonded with the first seal ring, and the outer rim of the first seal ring is close to bearing outer ring;
Inner ring opposite side is provided with back-up ring, and the periphery of back-up ring is thin rounded flakes, and the peripheral thin slice circumference profile of back-up ring is bonded with the second seal ring, and the outer rim of the second seal ring is close to bearing outer ring.
The material of the first seal ring and the second seal ring is fluorine rubber.
In the lip limit of the first seal ring and the second seal ring, embedded in wire spring circle respectively, the elastic force of mat steel wire fits tightly the first seal ring and the second seal ring on outer ring.
The beneficial effects of the utility model are:
Two end faces of bearing are all provided with seal arrangement, prevent dust and impurity from entering in raceway, allow again that lubricant oil infiltrates in slideway from filter screen circle side simultaneously, guarantee that bearing can rotate like a cork smoothly, reduce fault, increase the service life.

Description of reference numerals:
1 outer ring, 2 inner rings, 3 retainers, 4 rolling elements, 5 back-up rings, 6 thin slices, 7 first seal rings, 8 second seal rings, 9 first steel traveler, 10 second steel traveler, 11 filter screen circles, 12 bolts.
Embodiment
Now by reference to the accompanying drawings the utility model is described in further details:
A kind of structure of sealed type roller bearing as shown in Figure 1 to 4, comprises outer ring 1, inner ring 2, retainer 3, roller 4.Be provided with retainer 3 between inner ring 2 and outer ring 1, retainer 3 is provided with roller 4, and cylindrical roller 4 can roll or slide in the slideway of outer ring 1 and inner ring 2, and retainer 3 is separated into equal distance cylindrical roller 4, and shaft strength is even, guarantees to roll and carries out smoothly.Outer ring 1 and inner ring 2 the same side are processed with circular groove respectively, use and hold filter screen circle 11 and the first seal ring 7; The groove axial depth of outer ring 1 is larger than the groove axial depth of inner ring 2, makes not swipe between filter screen circle 11 and the outer ring 1 rotated corresponding thereto; The groove of inner ring 2 secures filter screen circle 11 with screw 12, the filter screen circle 11 material manufacture that can keep off dust, energy oil impregnate, outer rim filter screen circle 11 peripheral circumferential profiles being bonded with the first seal ring 7, first seal ring 7 is close to bearing outer ring 1;
Inner ring 2 opposite side is provided with back-up ring 5, and the periphery of back-up ring 5 is thin rounded flakes 6, and the outer rim peripheral thin slice 6 circumference profile of back-up ring 5 being bonded with the second seal ring 8, second seal ring 8 is close to bearing outer ring 1.
The material of the first seal ring 7 and the second seal ring 8 is fluorine rubber, and fluorine rubber has excellent wear resistance, can slow down wearing and tearing, ensures the endurance of sealing effect.
In the lip limit of the first seal ring 7 and the second seal ring 8, embedded in wire spring circle respectively, the elastic force of mat steel wire to fit tightly on outer ring 1 the first seal ring 7 and the second seal ring 8.
