Abstract
The invention relates to the field of a sealed bearing, and particularly relates to an ultra-wide lip contact sealed bearing. The ultra-wide lip contact sealed bearing provided by the invention has simple and ingenious design, adopts ultra-wide lip slot design, and has very high waterproof and anti-oil-penetration performance. The ultra-wide lip contact sealed bearing has the advantage of simple and ingenious design; the width of an ultra-wide lip slot is increased from previous 0.9mm to 1.6mm, so that the frictional drag between an ultra-wide lip contact sealing ring and an outer ring is increased, the ultra-wide lip contact sealing ring and the outer ring operate synchronously, and water seepage and oil penetration are effectively prevented.
Description
Technical field
The present invention relates to stuffing box bearing field, be specifically related to a kind of super wide lips contact type seal bearing.
Background technique
In the past in special bearing Seal Design, the epipharynx of seal ring and interior ring are contact-type, have larger resistance, the outer lip of seal ring and outer shroud also have resistance, but epipharynx and interior loop contacts resistance are large and the contact resistance of outer shroud and outer lip, once bearing rotary, seal ring will be under the effect of resistance be held relatively motionlessly along with interior environmental protection, and outer shroud rotates alone, for a long time will be ring wear, waterproof, seepage-proof oil performance just decline greatly, final cisco unity malfunction.
Summary of the invention
In order to address the above problem, the present invention proposes a kind of super wide lips contact type seal bearing, simplicity of design is ingenious, adopts the design of super wide lip groove, has very high waterproof, seepage-proof oil performance.
In order to reach foregoing invention object, the present invention proposes technological scheme:
Super wide lips contact type seal bearing, it comprises outer shroud, interior ring and ball, outer shroud bosom has semi-circular recesses, interior ring has semi-circular recesses in the middle of outside, interior ring is contained between outer shroud inside and interior ring and outer shroud has ball to be stuck in semi-circular recesses, and described outside, ball both sides is that super wide lipped joint contact-type sealing ring is housed between outer shroud and interior ring; Described outer shroud and super wide lipped joint contact-type sealing ring contact position have super wide lip groove; Described interior ring and super wide lipped joint contact-type sealing ring contact position have slope shape groove.
Described super wide lipped joint contact-type sealing ring one end is horizontal contact ring, and centre is vertical contact ring, and the other end is oblique contact ring, and horizontal contact ring is positioned at super wide lip groove, and vertical contact ring is positioned at ball outside, and oblique contact ring is positioned at slope shape groove; In described super wide lipped joint contact-type sealing ring, be designed with stiffening rib.
Described super wide lip well width is 1.6mm.
Advantage of the present invention is that simplicity of design is ingenious, the width of super wide lip groove is increased to 1.6mm from 0.9mm in the past, the increase of super wide lip well width increases the surface friction drag of super wide lipped joint contact-type sealing ring and outer shroud, make super wide lipped joint contact-type sealing ring and outer ring synchronous operation, effectively prevent infiltration, oil impregnate.
Brief description of the drawings
Fig. 1 is schematic diagram of the present invention.
Fig. 2 is the enlarged diagram of local A of the present invention position.
Embodiment
Introduce for the present invention is further described, introduce below in conjunction with Figure of description:
With reference to accompanying drawing 1, super wide lips contact type seal bearing, it comprises outer shroud 1, interior ring 2 and ball 3, outer shroud 1 bosom has semi-circular recesses, interior ring has semi-circular recesses in the middle of outside, interior ring 2 is contained between outer shroud 1 inside and interior ring 2 and outer shroud 1 has ball 3 to be stuck in semi-circular recesses, and described ball 3 outsides, both sides are that super wide lipped joint contact-type sealing ring 4 is housed between outer shroud and interior ring 2; Described outer shroud 1 has super wide lip groove 5 with super wide lipped joint contact-type sealing ring 4 contact positions; Described interior ring 2 has slope shape groove with super wide lipped joint contact-type sealing ring 4 contact positions.
With reference to Fig. 2, described super wide lipped joint contact-type sealing ring 4 one end are horizontal contact rings, and centre is vertical contact ring, the other end is oblique contact ring, horizontal contact ring is positioned at super wide lip groove 5, and vertical contact ring is positioned at ball 3 outsides, and oblique contact ring is positioned at slope shape groove; In described super wide lipped joint contact-type sealing ring 4, be designed with stiffening rib 41; Horizontal contact ring is to be designed to super wide lip contact ring, matches like this with super wide lip groove 5.
Described super wide lip groove 5 width are 1.6mm.
This design bearing is used, courageously start precedent, open super wide lip groove to 1.6mm in outer race inner side, the width of super wide lip groove broadens, the surface of contact of super wide lipped joint contact-type sealing ring and outer shroud is increased, frictional force also increases, super wide lipped joint contact-type sealing ring and outer shroud between frictional force be greater than the frictional force between super wide lipped joint contact-type sealing ring and interior ring, therefore will super wide lipped joint contact-type sealing ring when bearing rotary and outer shroud simultaneously rotating photo for bearing inner ring, meet the sealing theory of design bearing completely, more perfectly sealing, greatly increase the working life of bearing.
