Abstract
The utility model relates to a sealing element, in particular to a bidirectional backflow oil seal with a replaceable lip. The oil seal comprises a frame, a seal body and a spring. The oil seal is characterized in that the lip sealing part of the seal body is provided with a lip ring structure combined with the lip sealing part, an inner lip of the lip ring is a unidirectional or bidirectional helical line or an annular contact belt, and the work surface of the lip ring is provided with bidirectional backflow threads. Through the replaceable improvement design for the lip part which is easily abraded and aged, the oil seal having seal property failure can conveniently and quickly have the sealing effect again. The oil seal also has bidirectional backflow effect and keeps excellent sealing effect so as to meet the requirements of actual conditions.
Description
Technical field
The utility model relates to a kind of Sealing, especially a kind of bidirectional-reflux oil sealing of replaceable lip.
Background technique
Outside framework oil seal is one of staple product of present field of sealing technology, under the prerequisite that guarantees Sealing Performance of Oil Seal, how to save and make the required material of outside framework oil seal and the electric power energy of sulfidation, the oil sealing that how to use the simplest method and the fastest time to make that sealability lost efficacy has the effect of sealing again, and becoming has problem to be solved.For this reason, need a kind of oil sealing that can make quickly and easily that sealability lost efficacy to have the oil sealing of sealing effect again, and have the bidirectional-reflux effect, keep excellent sealing effect, satisfy the needs of actual conditions with this.
The model utility content
The bidirectional-reflux oil sealing of a kind of replaceable lip of the present utility model, by the lip position of easy wear and aging being carried out replaceable improvement design, make its oil sealing that can make quickly and easily that sealability lost efficacy have sealing effect again, and has the bidirectional-reflux effect, keep excellent sealing effect, thereby satisfy the needs of actual conditions.
The technological scheme that the utility model adopted is:
A kind of bidirectional-reflux oil sealing of replaceable lip, comprise skeleton, seal and spring, it is characterized in that: the lip seal position of seal is provided with combined with it lip ring structure, the inner lip of lip ring is unidirectional or two-way helix or annular contact zones, and the working surface of lip ring is provided with the bidirectional-reflux line.
The bidirectional-reflux oil sealing of described replaceable lip, bidirectional-reflux line are the waveform or the zigzag structure of wall scroll formula or many formulas.
The bidirectional-reflux oil sealing of described replaceable lip, bidirectional-reflux line are made as the highly gradient structure to the lip direction.
The bidirectional-reflux oil sealing of described replaceable lip, the inner lip of lip ring is designed to the interference structure.
The bidirectional-reflux oil sealing of described replaceable lip, the faying surface of lip ring matches with the moulding angle at the lip seal position of seal.
Like this when work, when seal and lip ring combined, but when also not starting working, these two-part are in free state, and when the two during as the sealing position of an integral installation on machine, because running shaft is to the effect of lip ring radial pressure, and axle and the fricative heat of lip ring, make that the air between two faying surfaces is discharged and fitted tightly together, like this, just produce adsorption force each other, thereby made the sealing that fits like a glove of whole faying surface; Again because seal is generally rubber product, so the cylindrical of its lip ring and contacting of seal are the contacts between the rubber, its friction factor is much bigger more than the rotation coefficient of contact friction of the working surface of lip ring and metal running shaft, therefore the cylindrical surface of contact of lip ring and the lip seal position of seal can not produce relative movement, in addition, the backflow effeet of bidirectional-reflux line makes the oil that is about to reveal get back in the Seal cage, thereby keeps good sealing effect.
The bidirectional-reflux oil sealing of a kind of replaceable lip of the present utility model, by the lip position of easy wear and aging being carried out replaceable improvement design, make its oil sealing that can make quickly and easily that sealability lost efficacy have sealing effect again, and has the bidirectional-reflux effect, keep excellent sealing effect, thereby satisfy the needs of actual conditions.
Description of drawings
Fig. 1 is the bidirectional-reflux oil seal structure schematic representation of a kind of replaceable lip of the present utility model.
Wherein, 1 is skeleton, and 2 is seal, and 3 is spring, and 4 is the working surface of lip ring, and 5 is the bidirectional-reflux line, and 6 is the faying surface of lip ring.
Embodiment
Embodiment
As shown in Figure 1, a kind of bidirectional-reflux oil sealing of replaceable lip comprises skeleton 1, seal 2 and spring 3, it is characterized in that: the lip seal position of seal 2 is provided with combined with it lip ring structure, the inner lip of lip ring is the one-way spiral line, and the working surface 4 of lip ring is provided with bidirectional-reflux line 5; Bidirectional-reflux line 5 is many formula zigzag structures to the highly gradient of lip direction; The inner lip of lip ring is designed to the interference structure; The faying surface 6 of lip ring matches with the moulding angle at the lip seal position of seal.
Like this when work, when seal 2 and lip ring combined, but when also not starting working, these two-part are in free state, and when the two during as the sealing position of an integral installation on machine, because running shaft is to the effect of lip ring radial pressure, and axle and the fricative heat of lip ring, make that the air between two faying surfaces is discharged and fitted tightly together, like this, just produce adsorption force each other, thereby made the sealing that fits like a glove of whole faying surface; Again because seal is generally rubber product, so the cylindrical of its lip ring and contacting of seal 2 are the contacts between the rubber, its friction factor is much bigger more than the rotation coefficient of contact friction of the working surface of lip ring and metal running shaft, therefore the cylindrical surface of contact of lip ring and the lip seal position of seal can not produce relative movement, in addition, the backflow effeet of bidirectional-reflux line 5 makes the oil that is about to reveal get back in the Seal cage, thereby keeps good sealing effect.
The bidirectional-reflux oil sealing of a kind of replaceable lip of the present utility model, by the lip position of easy wear and aging being carried out replaceable improvement design, make its oil sealing that can make quickly and easily that sealability lost efficacy have sealing effect again, and has the bidirectional-reflux effect, keep excellent sealing effect, thereby satisfy the needs of actual conditions.
Obviously, the foregoing description of the present utility model only is for the utility model example clearly is described, and is not to be qualification to mode of execution of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here can't give exhaustive to all mode of executions.Everyly belong to the row that conspicuous variation that the technical solution of the utility model extends out or change still are in protection domain of the present utility model.
