Abstract
The utility model relates to a seal piece, especially a combined PTFE antifriction oil seal, comprising an outer frame, a PTFE oil seal body and an inner seal body, characterized in that: the oil seal also comprises a PTFE upper antifriction block and a PTFE lower antifriction block, the PTFE lower antifriction block is mounted at the bottom of the outer frame, the inner seal body is arranged between the PTFE upper antifriction block and the PTFE lower antifriction block; radial interference fit is present between the PTFE upper antifriction block, the PTFE oil seal body and the outer frame and the PTFE upper antifriction block and the outer frame freely rotate relative to the PTFE oil seal body by a certain axial movement amount. The combined PTFE antifriction oil seal solves the problems of the current common combined oil seal that: the friction and the rotation resistance are over large, the working state of the oil seal is relative bad and the service life is short and has advantages of very low friction coefficient, less friction heat, small rotation resistance, high temperature resistance and eccentric resistance and greatly increases the service life of the oil seal and satisfies the requirement of the actual condition.
Description
Technical field
The utility model relates to a kind of Sealing, especially a kind of combined type PTFE anti-attrition oil sealing.
Background technique
The trailer vehicle bridge ubiquitous problem of combined type oil sealing commonly used is when mounted at present, relative position between the inside and outside assembly can't accurately be controlled, after installing, can interfere between the inside and outside assembly, thereby can produce a large amount of frictional heat at start of run, it is too high to cause the oil sealing position to be heated up, rubbery sealed body especially seal lip is aging, reduce oil sealing working life and sealability, because high temperature can cause deterioration of lubricant, also can reduce the performance of whole bridge simultaneously.Need a kind of can reducing friction and the combined type oil sealing of rotational resistance for this reason, thereby improve the oil sealing applying working condition, prolong oil sealing working life, satisfy the needs of actual conditions with this.
The model utility content
Combined type PTFE anti-attrition oil sealing of the present utility model, it has solved ubiquitous friction of combined type oil sealing commonly used at present and the problem that rotational resistance is excessive, the oil sealing working state is relatively poor, working life is short, it has that friction factor is very low, frictional heat is few, rotational resistance is little, the advantage of high temperature resistant and anti-off-centre, improve oil sealing working life greatly, can satisfy the needs of actual conditions.
The technological scheme that the utility model adopted is:
A kind of combined type PTFE anti-attrition oil sealing, comprise outer skeleton, PTFE oil seal body and interior seal, it is characterized in that: comprise that also PTFE goes up anti-attrition piece under anti-attrition piece and the PTFE, the anti-attrition piece is installed on the bottom of outer skeleton under the PTFE, and interior seal is under anti-attrition piece and the PTFE on the PTFE between the anti-attrition piece.
Described combined type PTFE anti-attrition oil sealing, anti-attrition piece radial interference is installed on the bottom of outer skeleton under its PTFE.
Described combined type PTFE anti-attrition oil sealing, its PTFE are gone up the anti-attrition piece, the PTFE oil seal body is a radial interference fit with outer skeleton.
Described combined type PTFE anti-attrition oil sealing, seal can carry out freely rotating with respect to the PTFE oil seal body in it.
Described combined type PTFE anti-attrition oil sealing, seal can have certain axial internal clearance in it.
Like this in when work, combined type PTFE anti-attrition oil sealing of the present utility model when mounted, interior seal can go up that the anti-attrition piece contact under anti-attrition piece or the PTFE with PTFE; In oil sealing when running,, the place, contact position can produce friction, but since the contact position be the PTFE material with metal between contact, friction factor is very low, so frictional heat is few, and rotational resistance is little, making has great raising in working life of oil sealing.
Combined type PTFE anti-attrition oil sealing of the present utility model, it has solved ubiquitous friction of combined type oil sealing commonly used at present and the problem that rotational resistance is excessive, the oil sealing working state is relatively poor, working life is short, it has that friction factor is very low, frictional heat is few, rotational resistance is little, the advantage of high temperature resistant and anti-off-centre, improve oil sealing working life greatly, can satisfy the needs of actual conditions.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and embodiments:
Fig. 1 is the utility model combined type PTFE anti-attrition oil seal structure schematic representation.
Among the figure, 1 is outer skeleton, and 2 is the PTFE oil seal body, and 3 for PTFE goes up the anti-attrition piece, and 4 is anti-attrition piece under the PTFE, and 5 is interior seal.
Embodiment
Embodiment
As shown in Figure 1, combined type PTFE anti-attrition oil sealing, comprise outer skeleton 1, PTFE oil seal body 2 and interior seal 5, it is characterized in that: comprise that also PTFE goes up anti-attrition piece 4 under anti-attrition piece 3 and the PTFE, anti-attrition piece 4 radial interference are installed on the bottom of outer skeleton 1 under the PTFE, the last anti-attrition piece 3 of PTFE, PTFE oil seal body 2 are radial interference fit with outer skeleton 1, interior seal 5 is under anti-attrition piece 3 and the PTFE on the PTFE between the anti-attrition piece 4, interior seal 5 can carry out freely rotating with respect to PTFE oil seal body 2, and it can have certain axial internal clearance.
Like this in when work, combined type PTFE anti-attrition oil sealing of the present utility model when mounted, interior seal 5 can go up that anti-attrition piece 4 contact under anti-attrition piece 3 or the PTFE with PTFE; In oil sealing when running,, the place, contact position can produce friction, but since the contact position be the PTFE material with metal between contact, friction factor is very low, so frictional heat is few, and rotational resistance is little, making has great raising in working life of oil sealing.
Combined type PTFE anti-attrition oil sealing of the present utility model, it has solved ubiquitous friction of combined type oil sealing commonly used at present and the problem that rotational resistance is excessive, the oil sealing working state is relatively poor, working life is short, it has that friction factor is very low, frictional heat is few, rotational resistance is little, the advantage of high temperature resistant and anti-off-centre, improve oil sealing working life greatly, can 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.
