Abstract
The utility model discloses a seal seat for a floating oil seal, which comprises a floating seal seat, wherein a seat cavity is arranged in the floating seal seat, the inner wall of the seat cavity is provided with a main arc-shaped conical surface matched with a rubber ring for use, the radian of the main arc-shaped conical surface is pi/3, one end of the main arc-shaped conical surface extends to form an auxiliary arc-shaped conical surface, and the radian of the auxiliary arc-shaped conical surface is pi/2.
Description
Technical Field
The utility model relates to the technical field of floating oil seals, in particular to a seal seat for a floating oil seal.
Background
The floating oil seal is a mechanical sealing mode, and is a rotary dynamic sealing device developed to adapt to a severe working environment. The mechanical sealing device with the end face dynamic sealing function in a special form has the characteristics of simple maintenance, good sealing performance, long service life and simple structure, is mainly applied to engineering machinery and other machinery, and structurally mainly comprises a pair of floating seal rings, a rubber ring and a floating seal seat.
But the floating oil seal among the prior art, rubber circle, floating seal ring cooperation work, and the rubber circle inlays between the conical surface, because general conical surface all is not the radian, and is general with the degree of agreeing with the rubber circle, wearing and tearing and dislocation appear easily, have reduced life.
Disclosure of Invention
In order to solve the defects of the prior art, the utility model provides a seal seat for a floating oil seal, which solves the problems in the prior art.
In order to achieve the purpose, the utility model adopts the technical scheme that:
the utility model provides a seal seat for floating oil seal, is including floating the seal seat, the inside of floating the seal seat is equipped with the seat chamber, the inner wall in seat chamber is equipped with the main arc conical surface that uses with the cooperation of rubber ring, the radian of main arc conical surface is pi/3, and one end extends to vice arc conical surface, the radian of vice arc conical surface is pi/2.
Furthermore, the floating seal seat is composed of an upper seat and a lower seat.
Furthermore, the combination of the main arc-shaped conical surface and the auxiliary arc-shaped conical surface is ear-shaped.
Compared with the prior art, the utility model has the advantages that:
the design of the conical surface is improved, and the double-arc design is adopted, so that the rubber ring is matched, the service life is prolonged, and the rubber ring is prevented from being separated.
Drawings
FIG. 1 is a schematic structural view of the present invention;
fig. 2 is a schematic view of the internal structure of the present invention.
Reference numerals: the floating seal seat comprises a floating seal seat, an upper seat 1, a lower seat 2, a seat cavity 101, an auxiliary arc-shaped conical surface 3 and a main arc-shaped conical surface 4.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings, and it is to be understood that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example 1, as shown in fig. 1 and 2:
the utility model provides a seal seat for floating oil seal, including floating the seal seat, it comprises upper seat 1 and lower seat 2, the inside of floating the seal seat is equipped with seat chamber 101, set up one at the inner wall of seat chamber 101 with the cooperation of rubber ring main arc conical surface 4 that uses, the radian of main arc conical surface 4 sets up to pi/3 simultaneously, extend its one end, form vice arc conical surface 3, the radian with vice arc conical surface 3 sets up to pi/2, main arc conical surface 4 is ear with the combination of vice arc conical surface 3 simultaneously.
When the floating seal device is used specifically, the floating seal rings 2 need to be used in pairs, one is rotated along with a rotating part (moving ring), the other is relatively static (fixed ring), a rubber ring with a circular section is respectively arranged at conical surfaces between the moving ring and the floating seal seat 1 and between the fixed ring and the floating seal seat 1, the rubber ring is axially compressed in a sealing cavity formed by the floating seal seat 1 (namely the main arc-shaped conical surface 4) to generate deformation under the action of the assembling pretightening force, and the main arc-shaped conical surface 4 can be matched with the rubber ring, so that the device is more convenient to use, and the service life of the whole device is prolonged.
Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention, and that variations, modifications, substitutions and alterations can be made in the above embodiments by those of ordinary skill in the art without departing from the principle and spirit of the present invention.
