Description
Technical Field
The utility model relates to a sealing washer technical field specifically is a novel two lips combination formula skeleton seal circle.
Background
The existing loader gearbox assembly with the weight of less than 3 tons is provided with a framework oil seal with a single-lip seal at the position of a core of a torque converter in order to prevent oil in the gearbox from flowing out of a shell of the torque converter, but the single-lip seal is poor in sealing effect and often causes oil leakage.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a novel two lips combination formula skeleton sealing washer to the single lip skeleton oil blanket that provides in solving above-mentioned background art seals the effect not good, often appears the problem of oil leak phenomenon, in order to reach improvement sealed effect, and then improves product quality's purpose.
In order to achieve the above object, the utility model provides a following technical scheme:
a novel double-lip combined type framework sealing ring comprises a sealing ring outer ring and a sealing ring inner ring, wherein the sealing ring inner ring is tightly pressed and installed in the sealing ring outer ring.
Preferably, the sealing washer outer lane includes outer lane metal framework, outer lane metal framework cross-section is the L shape, and the parcel has the outer lane rubber body on its outer wall, the lip root of outer lane rubber body is provided with the outer lane spring of cramping.
Preferably, the inner ring of the sealing ring comprises an inner ring metal framework, the cross section of the inner ring metal framework is L-shaped, an inner ring rubber body wraps the outer wall of the inner ring metal framework, and an inner ring tightening spring is arranged at the lip-shaped root of the inner ring rubber body.
Compared with the prior art, the beneficial effects of the utility model are that:
this kind of novel two lips combination formula skeleton seal circle has set up two sets of lip seal, adopts two lips mouth seal structure, to the seepage or the effect of leaking of avoiding lubricating oil play the dual fail-safe, can effectively guarantee good sealed effect, satisfies the operation requirement.
Drawings
FIG. 1 is a schematic structural view of the present invention;
in the figure: 1. the sealing ring comprises a sealing ring outer ring 101, an outer ring metal framework 102, an outer ring rubber body 103, an outer ring tightening spring 2, a sealing ring inner ring 201, an inner ring metal framework 202, an inner ring rubber body 203 and an inner ring tightening spring.
A. A workpiece, B, a workpiece shaft.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1, the present invention provides a technical solution: a novel double-lip combined type framework sealing ring comprises a sealing ring outer ring 1, an outer ring metal framework 101, an outer ring rubber body 102, an outer ring tightening spring 103, a sealing ring inner ring 2, an inner ring metal framework 201, an inner ring rubber body 202 and an inner ring tightening spring 203. The inner ring 2 of the sealing ring is tightly pressed in the outer ring 1 of the sealing ring to form a combined type framework sealing ring with a double-lip sealing structure.
The sealing ring outer ring 1 comprises an outer ring metal framework 101, the cross section of the outer ring metal framework 101 is L-shaped, an outer ring rubber body 102 wraps the outer wall of the outer ring metal framework, an outer ring tightening spring 103 is arranged at the lip root of the outer ring rubber body 102, and the outer ring rubber body 102 can be effectively tightened to achieve a sealing function.
The inner ring 2 of the sealing ring comprises an inner ring metal framework 201, the cross section of the inner ring metal framework 201 is L-shaped, an inner ring rubber body 202 wraps the outer wall of the inner ring metal framework, and an inner ring tightening spring 203 is arranged at the root of the lip shape of the inner ring rubber body 202 and can effectively tighten the inner ring rubber body 202 to realize a sealing function.
The utility model discloses a theory of operation: firstly, the inner ring 2 of the sealing ring is pressed into the outer ring 1 of the sealing ring, then the combined double-lip combined type framework sealing ring is pressed into the inner hole of the workpiece A, then the workpiece shaft B sequentially penetrates through the inner hole of the double-lip combined type framework sealing ring, and under the action of the outer ring tightening spring 103 and the inner ring tightening spring 203, two lips of the sealing ring are tightly attached to the workpiece shaft B, so that the purpose of sealing the double lips is achieved, the sealing effect is improved, and the oil leakage phenomenon is avoided.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
