Abstract
The utility model relates to a lip type sealed bearing. The lip type sealed bearing comprises a bearing outer ring and a bearing inner ring, wherein a steel ball is arranged between the bearing outer ring and the bearing inner ring; a sealing cover is also arranged between the bearing outer ring and the bearing inner ring; the bottom of the sealing cover is provided with three contact lips; and the contact compactness of the three contact lips and the bearing inner ring is sequentially decreased from inside to outside. The package size of a sealing piece is reduced; the elasticity of the sealing piece is strengthened; the sealing performance of the bearing is improved; water vapor, dust, turfgrass clippings and the like can be effectively prevented from entering the bearing during work; the wear of the bearing is reduced; and the service life of the bearing is prolonged.
Description
Technical field
The utility model relates to a kind of bearing, especially a kind of lip seal bearing.
Background technique
The seal ring that carries on the existing bearing has Sealing and skeleton, the interior Zhou Yousan of Sealing the identical contact lip of thickness that is arranged in parallel; Contact with the outer diametric plane of bearing inner race, the monolateral magnitude of interference of the outer diametric plane of contact lip and bearing inner race is about 0.4mm, and the skeleton outer side surface has the rib of positioning seals; Its closing in diameter than the big 1.0mm of bearing inner race external diameter about, this structure makes the contact lip of Sealing and the magnitude of interference between the bearing inner race external diameter too small, skeleton is too much to the containing of Sealing; The elasticity of Sealing is not enough, causes the sealability of seal ring to reduce, and has influenced the lubrication effect of bearing; For the bearing of under the environment that is mixed with steam, dust, grass bits, working for a long time; This sealing configuration form is just more inadequate, and dust etc. are easy to infiltrate bearing inside, and trickle particle and lubricant grease are lumped together; Aggravate the wearing and tearing of bearing, finally caused the bearing shortening greatly in working life.
The model utility content
The technical problem that the utility model will solve is: even a kind of lip seal bearing that under abominable working environment, also has good sealability is provided.
The utility model solves the technological scheme that its technical problem adopted: a kind of lip seal bearing; Comprise bearing outer ring and bearing inner race; Be provided with steel ball between described bearing outer ring and the bearing inner race; Also be provided with sealing cover between described bearing outer ring and the bearing inner race, described sealing cover bottom has three contact lips, and the closeness of contact of described three contact lips and bearing inner race successively decreases from inside to outside successively.
Say that further the described sealing cover of the utility model is made up of rubber parts and skeleton, described rubber parts and skeleton bond together; The thickness of the contact lip of sealing cover ragged edge is greater than the thickness of two other contact lip.
The beneficial effect of the utility model is to have solved the defective that exists in the background technique, the radial interference amount increasing of Sealing contact lip and the outer diametric plane of bearing inner race; The outer diametric plane of contact lip and bearing inner race combines tighter, and the thickening of contact lip thickness makes that the diametric plane contact length extends outside itself and the bearing inner race; Shorten the rib of skeleton, reduce containing amount, strengthened the elasticity of Sealing Sealing; Improved the sealability of bearing; Can prevent effectively in the work that steam, dust, grass bits etc. from sneaking into bearing inside, reduce the wearing and tearing of bearing, prolong the operating life of bearing.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the structural representation of the preferred embodiment of the utility model;
Among the figure: 1, bearing outer ring; 2, bearing inner race; 3, steel ball; 4, sealing cover; 5, contact lip; 41, rubber parts; 42, skeleton.
Embodiment
Combine accompanying drawing and preferred embodiment that the utility model is done further detailed explanation now.These accompanying drawings are the schematic representation of simplification, the basic structure of the utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
A kind of lip seal bearing as shown in Figure 1; Comprise bearing outer ring 1 and bearing inner race 2; Be provided with steel ball 3 between described bearing outer ring 1 and the bearing inner race 2; Also be provided with sealing cover 4 between described bearing outer ring 1 and the bearing inner race 2, described sealing cover 4 bottoms have three contact lips 5, and described three contact lips 5 successively decrease with the closeness of contact of bearing inner race 2 from inside to outside successively.
The described sealing cover 4 of the utility model is made up of rubber parts 41 and skeleton 42, and described rubber parts 41 bonds together with skeleton 42; The thickness of the contact lip of sealing cover 4 ragged edges is greater than the thickness of two other contact lip.
The radial interference amount of described Sealing contact lip of the utility model and the outer diametric plane of bearing inner race strengthens, and the contact lip combines tighter with the outer diametric plane of bearing inner race, the thickening of contact lip thickness; Itself and the outer diametric plane contact length of bearing inner race are extended; Shorten the rib of skeleton, reduce containing amount, strengthened the elasticity of Sealing Sealing; Improved the sealability of bearing; Can prevent effectively in the work that steam, dust, grass bits etc. from sneaking into bearing inside, reduce the wearing and tearing of bearing, prolong the operating life of bearing.
The just embodiment of describing in the above specification of the utility model; The various fleshes and bloods that illustrate not the utility model constitute restriction; Under the those of ordinary skill of technical field after having read specification can to before described embodiment make an amendment or be out of shape, and do not deviate from the essence and the scope of model utility.
