Abstract
The utility model relates to a special touch seal ring for deep groove bearing; the sealing form of the seal ring adopts double-lip touch sealing; the double lips are respectively an outer lower lip and an inner lower lip; the double lips are in interference fit with the inner ring of the bearing; an inner upper lip untouched with the inner ring of the bearing is arranged obliquely above the inner lower lip; the inner upper lip, the outer lower lip and the inner lower lip are connected integrally; and the inside of the seal ring is provided with a steel skeleton increasing the rigidity of the seal ring. The special touch seal ring for deep groove bearing has the advantages of excellent sealing performance, sufficient lubrication of bearing and long service life.
Description
Technical field
The utility model relates to the special-purpose touch seal ring of the good zanjon bearing of a kind of sealability, belongs to seal ring and makes the field.
Background technique
Seal ring is mainly used to grease-proof and waterproof preserving and sealing gas, prevent to reveal, sealing in deep groove ball bearing, two kinds of the seal ring of branch contact-type and contactless seal rings, though contactless seal ring starting torque is little, sealability is bad, leaks grease easily, have the seal ring of a class contact-type to have only a contact lip to contact with bearing inner race, its sealability has narrow limitation.
Summary of the invention
Purpose of design: avoid the deficiency in the background technique, design the special-purpose touch seal ring of a kind of zanjon bearing, it is lips contact seal, and sealability is good.
Design proposal: in order to realize above-mentioned purpose of design.The utility model structurally, the seal form of seal ring adopts lips contact seal, lips are respectively external lower lip and endolabium, lips and bearing inner race interference fit, the endolabium oblique upper have with bearing inner race discontiguous in upper lip, interior upper lip, external lower lip and endolabium three are connected as a single entity, and the inside of seal ring is provided with the Steel Skeleton that increases the seal ring rigidity.1, the design of little V-type groove is arranged between endolabium and the external lower lip, is one of technical characteristics of the present utility model.The purpose of doing like this is: make endolabium and external lower lip form the labyrinth, the improvement sealability; 2, the design of endolabium and external lower lip and bearing inner race interference fit is two of a technical characteristics of the present utility model.The purpose of doing like this is: strengthened sealability greatly, prevented that grease from leaking; 3, near endolabium big V-type groove is arranged between interior upper lip and the endolabium, the external lower lip oblique upper has the design of a trapezoidal groove, is three of technical characteristics of the present utility model.The purpose of doing like this is: improve the structure of endolabium and external lower lip, make endolabium and the deliquescing of external lower lip root, increase the pliability and the elasticity of endolabium and external lower lip, reduce the internal pressure that endolabium bears simultaneously, can prevent effectively that grease from leaking; 4, interior upper lip and external lower lip are thick and hard, and interior upper lip is the design of helical teeth shape, are four of technical characteristicss of the present utility model.The purpose of doing like this is: interior upper lip guiding lubricating grease circulates bearing inside, guarantees the good lubrication of bearing, and external lower lip sealing structure performance is good, long service life.
Technological scheme: the special-purpose touch seal ring of zanjon bearing, the seal form of seal ring adopts lips contact seal, lips are respectively external lower lip and endolabium, lips and bearing inner race interference fit, the endolabium oblique upper have with bearing inner race discontiguous in upper lip, interior upper lip, external lower lip and endolabium three are connected as a single entity, and the inside of seal ring is provided with the Steel Skeleton that increases the seal ring rigidity.
The utility model is compared with background technique, has excellent sealing performance, bearing lubrication abundance, long service life.
Description of drawings
Fig. 1 is the special-purpose touch seal ring of a zanjon bearing generalized section.
Embodiment
Embodiment 1: with reference to accompanying drawing 1.The special-purpose touch seal ring of zanjon bearing, the seal form of seal ring adopts lips contact seal, lips are respectively external lower lip 5 and endolabium 3, lips and bearing inner race interference fit, endolabium 3 oblique uppers have with bearing inner race discontiguous in upper lip 1, interior upper lip 1, external lower lip 5 and endolabium 3 threes are connected as a single entity, and the inside of seal ring is provided with the Steel Skeleton 7 that increases the seal ring rigidity.Little V-type groove 4 is arranged between endolabium 3 and the external lower lip 5, near endolabium 3 big V-type groove 2 is arranged between interior upper lip 1 and the endolabium 3, external lower lip 5 oblique uppers have a trapezoidal groove 6.Interior upper lip 1 and external lower lip 5 are thick and hard, and interior upper lip 1 is the helical teeth shape.
What need understand is: though the foregoing description is to the mentality of designing of the present utility model detailed text description of contrasting; but these text descriptions; just the simple text of the utility model mentality of designing is described; rather than to the restriction of the utility model mentality of designing; any combination, increase or modification that does not exceed the utility model mentality of designing all falls in the protection domain of the present utility model.
