Abstract
The utility model discloses a dustproof and sealed double-row tapered roller bearing. According to the technical scheme essentials provided by the utility model, the dustproof and sealed double-row tapered roller bearing comprises outer rings and inner rings, wherein a space ring is arranged between the inner rings; a retainer is arranged between each inner ring and each outer ring; each retainer is provided with double-row tapered rollers; a dustproof cover is arranged outside each retainer and is arranged between each inner ring and each outer ring; a framework is further arranged between each retainer and each dustproof cover; one side of each framework is mounted on each outer ring; a sealing ring is arranged adjacently on each framework; the inner side part of each sealing ring is provided with double layers of sealing lips; the sealing lips are arranged adjacently on the surface of each inner ring; dustproof and sealing performances are combined so as to effectively prevent large-grain dust, impurities, water and the like and effectively prolong the service life of the bearing.
Description
Technical field
The utility model relates to field of bearings, and more particularly, it relates to the double-row conical bearing that a kind of dust sealing combines.
Background technique
Tapered roller bearing mainly bears with Wei Zhu footpath radially, axial connected load, and tapered roller bearing is widely used in the industries such as automobile, milling train, mine, metallurgy, plastics machinery.Due to being widely used of tapered roller bearing; make tapered roller bearing must face the severe of working environment; current domestic patent has only set up a sealing configuration conventionally; often cannot effectively face the outside foreign material invasion such as large particle dust, iron scale is collected near sealing configuration; thereby reduce the working life of bearing; improve user's user cost, reduced oiling agent consumption.
Model utility content
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of double-row conical bearing of dust sealing, improves the working life of bearing, reduces user's user cost.
For achieving the above object, the utility model provides following technological scheme: comprise outer ring, inner ring, between inner ring, be provided with spacer ring, between inner ring and outer ring, be provided with retainer, retainer is provided with double-row conical, described retainer have a dust-proof cover outward and be also located at described inner ring and described outer ring between, between described retainer and described dust-proof cover, also settle skeleton, one side of skeleton is arranged on described outer ring, on described skeleton, be glued with seal ring, the inside portion of seal ring is provided with double-layer seal lip, and described sealing lip is close to described inner peripheral surface.
By adopting technique scheme, double-row conical bearing is added one deck protective housing and at seal ring, is provided with double-layer seal lip, the multi-sealed sealing effect that improves simultaneously, effectively prevent dust, impurity thing, water etc., improve sealability, improve bearing life and improve, reduce oiling agent consumption.
The utility model is preferably set to: described dust-proof cover is that flexible rubber forms, and dust-proof cover has several through holes, and aperture is 1-2mm.
By adopting technique scheme, when the contact protective housings such as larger particle dust, iron scale, impurity thing, protective housing can effectively rebound, evade, and opens preliminary filtration, reduces the carrying capacity of seal ring, increases the working life of bearing.

Embodiment
See figures.1.and.2 a kind of embodiment dustproof and double-row conical bearing that sealing combines of the utility model is described further.
A kind of dustproof and double-row conical bearing that sealing combines, comprise outer ring 1, inner ring 2, between inner ring 2, be provided with spacer ring 9, between inner ring 2 and outer ring 1, be provided with retainer 4, retainer 4 is provided with double-row conical 3, retainer 4 is outer to be had a dust-proof cover 5 and is also located between described inner ring 2 and described outer ring 1, dust-proof cover 5 is that flexible rubber forms, dust-proof cover 5 has several through holes, aperture is 1-2mm, between retainer 4 and dust-proof cover 5, also settle skeleton 6, one side of skeleton 6 is arranged on described outer ring 1, on described skeleton 6, be glued with seal ring 7, the inside portion of seal ring is provided with double-layer seal lip 8, described sealing lip is close to described inner peripheral surface.
Bearing is when operation, there is unavoidably entering of impurity, dust, when some larger impurity, dust contact protective housing, by flexible rubber on protective housing, rebounded, evade, only remaining little impurity, dust, water etc. enter seal ring, double-layer seal lip on seal ring is stopped impurity, dust, water etc. again, thereby reaches the working life of improving bearing.
The double-row conical bearing a kind of dustproof and that sealing combines above the utility model embodiment being provided is described in detail, for one of ordinary skill in the art, thought according to the utility model embodiment, all will change in specific embodiments and applications.In sum; this description should not be construed as restriction of the present utility model; other any any variation and modification of doing according to the constructed thought of the utility model and scope of patent protection or be equal to enforcement, is scope of patent protection of the present utility model and contains.
Claims (2)
