Abstract

The utility model relates to a floating sealing ring for shaft sealing and comprises round ring, the round ring is split, that is combined by two half rings, a ring groove is arranged on excircle wall of the round ring body and stretching along ring body to excircle wall, a extension spring is arranged in ring groove, the extension spring section is cylindrical form and linked with head and end, the extension spring is in tension condition, the round ring body can produce a force to inner circle wall by the elastic deformation of extension spring. A pin hole is arranged on end of round ring body in axial direction, when using, insert the positioning pin installed on internal wall slot into the pin hole, The utility model can joint tightly with shaft to make the up and down and side to side movement with the shaft in the minimum range and realize the dynamic seal with shaft, avoid effectively oil leakage with convenient assembly.

Description

Floating seal ring
Technical field
The utility model relates to shaft sealer, relates in particular to the floating seal ring that a kind of shaft sealing is used.
Background technique
The seal ring of shaft sealer use at present generally adopts the O RunddichtringO, the O RunddichtringO produces prestressing force by the extrusion-deformation of when assembling and reaches sealing effect, traditional seal ring all is to be stuck on the inwall of bearing, when axle moves, seal ring is actionless, can't realize dynamic seal (packing) between seal ring and the axle, the seepage-proof oil effect is not very desirable.
Summary of the invention
The utility model mainly is to solve conventional seals circle transfixion still when axle move, seal ring and spool between can't realize that dynamic seal (packing), seepage-proof oil effect are not very desirable technical problems; Provide a kind of and when axle moves, can move up and down, and realize dynamic seal (packing) between the axle, improve the floating seal ring of seepage-proof oil effect along with the axle work.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: the utility model comprises the ring-type circle body, the cylindrical wall of described ring-type circle body is provided with a circular groove, be provided with an extension spring in the circular groove, ring-type circle body tension is stretched spring deformation, and ring-type circle body inner round wall is had one power.Elastic strain by extension spring, make the internally round wall of ring-type circle body produce one power, inner round wall is tightly fitted with the axle of installing wherein, thereby makes floating seal ring do up and down motion along with the motion of axle, dynamic seal (packing) between realization and the axle effectively prevents oil impregnate.
As preferably, described circular groove is along the cylindrical wall extending circumferentially of ring-type circle body, and described extension spring cross section is cylindrical, and it is from beginning to end, and described extension spring is in extended state.Further guarantee inner round wall and the tightly applying of axle of installing wherein, the dynamic seal (packing) between realization and the axle effectively prevents oil impregnate.
As preferably, the degree of depth of described circular groove is more than or equal to the diameter of described extension spring.
As preferably, described ring-type circle body is branch half formula, is put together by two semi-rings.Be convenient to assembling, increase work efficiency.
As preferably, be axially arranged with a pin-and-hole on the end face of described ring-type circle body.During use, insert the locating stud of being located on the bearing inner wall groove in the pin-and-hole, guarantee the ring-type circle body in minimum zone, prevent that it from making excessive amount of motion along with axle is done to move up and down.
As preferably, also be provided with the circular groove of an extending circumferentially on the inner round wall of described ring-type circle body, play the recoil effect.
As preferably, the interior circular groove on the described ring-type circle body inner round wall is more shallow than the circular groove on the cylindrical wall.
As preferably, described ring-type circle body is made by high molecule plastic.Guarantee that the ring-type circle body is wear-resistant, high temperature resistant and have the good insulation performance performance.
The beneficial effects of the utility model are: by the elastic strain of extension spring, make the internally round wall of ring-type circle body produce one power, inner round wall is tightly fitted with the axle of installing wherein, thereby make floating seal ring do up and down motion along with the motion of axle, dynamic seal (packing) between realization and the axle effectively prevents oil impregnate.Simultaneously, the ring-type circle body adopts and divides half formula structure, makes installation very convenient; The employing high molecule plastic is made, and guarantees wear-resistant, high temperature resistant and the good insulation performance performance.
