Abstract
The utility model relates to a novel sealing ring which consists of a ring-shaped rubber body and a ring-shaped skeleton embedded on the inner side the rubber body. The surface of an outer lip of the rubber body is provided with an outer groove. An inner lip of the rubber body is provided with a groove. The novel sealing ring is characterized in that the outer surface of the inner lip of the rubber body is provided with an inner groove; and the inner groove is a groove formed in a mode that a straight line at an included angle of 50 degrees with the vertical direction and a straight line at an included angle of 20 degrees with the horizontal direction are smoothly connected by a fillet with the radius of 0.3mm. Compared with the prior art, the novel sealing ring has the advantages of simple structure and low cost. Moreover, the defect of contradiction between the sealing effect of a bearing and reduction of a friction force is effectively avoided.
Description
Technical field
The utility model relates to a kind of seal ring of shaft bearing, is specifically related to a kind of novel seal circle.
Background technique
Stuffing box bearing is that the seal ring outer lip is fixed on the bearing outer ring, and the inner ring of epipharynx and bearing has certain clearance.Existing seal ring epipharynx is straight, and when the gap was too big between the inner ring of bearing and the seal ring, sealing effect was poor, and the grease in the bearing race easily runs off, and the impurity in the external environment condition also enters bearing race easily; As the gap too hour, because the cumulative function of morpheme error, the seal ring epipharynx can be on circumference local contact bearing inner ring, in case touching bearing inner race, the seal ring epipharynx will produce bigger positive pressure, during the bearing rotation, under bigger positive pressure, can produce bigger frictional force, thus consumed power, and cause bearing temperature rise too high.
The model utility content
The purpose of this utility model is exactly the defective that exists at prior art, provides a kind of and can guarantee excellent sealing, and can reduce or stop to produce the novel seal circle of frictional force greatly.
Its technological scheme is: be made up of circular rubber body and the circular skeleton that is embedded in the rubber body inboard, the surface of rubber body outer lip is provided with outer channel, and its epipharynx is provided with groove, it is characterized in that: the outer surface of described rubber body epipharynx is provided with internal channel.
Wherein, described internal channel for two straight lines of 50 ° of angles of vertical direction and 20 ° of angles of substantially horizontal with the smooth groove that couples together formation of the fillet of radius 0.3mm.
The utility model has advantage simple in structure, with low cost compared with prior art, and effectively stopped the bearing seal effect and reduce friction between have conflicting shortcoming.
Description of drawings
Fig. 1 is a kind of embodiment's of the utility model structural section figure.
Embodiment
With reference to Fig. 1, a kind of novel seal circle is made up of circular rubber body 1 and the circular skeleton 2 that is embedded in rubber body 1 inboard, and the surface of rubber body 1 outer lip is provided with outer channel 3, its epipharynx is provided with groove 4, it is characterized in that: the outer surface of described rubber body 1 epipharynx is provided with internal channel 5.Described internal channel 5 for two straight lines of 50 ° of angle α of vertical direction and 20 ° of angle β of substantially horizontal with the smooth groove that couples together formation of the fillet R of radius 0.3mm.
The utility model has been removed outer surface some materials (rubber) exactly because increased internal channel 5, makes the attenuation that is connected between this novel seal circle and its epipharynx, and tie point is partially on one side.Make the epipharynx of sealing circle become soft yielding like this, also can not produce bigger positive pressure even touch bearing inner race, thus effectively stopped the bearing seal effect and reduce friction between existing conflicting problem.
Claims (2)
1. novel seal circle, form by circular rubber body and the circular skeleton that is embedded in the rubber body inboard, the surface of rubber body outer lip is provided with outer channel, and its epipharynx is provided with groove, it is characterized in that: the outer surface of described rubber body epipharynx is provided with internal channel.
2. novel seal circle according to claim 1 is characterized in that: described internal channel for two straight lines of 50 ° of angles of vertical direction and 20 ° of angles of substantially horizontal with the smooth groove that couples together formation of the fillet of radius 0.3mm.
