Abstract

The utility model discloses a floating oil seal convenient to install, which comprises a floating seal seat and a floating seal ring, wherein a rubber ring is arranged between the floating seal seat and the floating seal ring, the floating seal seat is provided with an inner conical surface I in contact with the rubber ring, one end of the inner conical surface I is provided with a side cambered surface corresponding to the rubber ring, the floating seal ring is provided with an inner conical surface II in contact with the rubber ring, and one end of the inner conical surface II is provided with a concave cambered surface corresponding to the rubber ring. It adopts the design of side cambered surface and indent cambered surface to set up certain radian, expand the space of interior conical surface, make things convenient for the rubber circle to install, the radian can be spacing simultaneously, avoids deviating from.

Description

Floating oil seal convenient to install

Technical Field

The utility model relates to the technical field of floating oil seals, in particular to a floating oil seal convenient to install.

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.

The space reserved by the inner conical surface of the existing floating oil seal is not enough, and the existing floating oil seal is not convenient enough when a rubber ring is assembled, so that a more convenient design is needed.

Disclosure of Invention

The utility model aims to provide a floating oil seal convenient to mount so as to solve the problems in the background technology.

In order to achieve the purpose, the utility model provides the following technical scheme:

the utility model provides an oil blanket floats convenient to installation, is equipped with the rubber circle including floating the seal seat, floating the seal ring between the two, float the seal seat be equipped with the inner conical surface I of rubber circle contact, the one end of inner conical surface I be equipped with the side cambered surface that the rubber circle corresponds, float the seal ring be equipped with the inner conical surface II of rubber circle contact, the one end of inner conical surface II be equipped with the indent cambered surface that the rubber circle corresponds.

Further, the radian of the side arc surface is pi/3.

Further, the radian of the concave cambered surface is pi/3.

Further, the rubber ring is made of fluororubber.

Compared with the prior art, the utility model has the beneficial effects that:

adopt the design of side cambered surface and indent cambered surface to set up certain radian, the space of conical surface in the extension makes things convenient for the rubber circle to install, and the radian can carry on spacingly simultaneously, avoids deviating from, adopts fluororubber preparation rubber ring simultaneously, can improve the wholeness ability.

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;

fig. 3 is a partially enlarged schematic view of the present invention.

In the figure: the floating seal device comprises a floating seal seat 1, a floating seal ring 2, a rubber ring 3, an inner conical surface II 4, an inner conical surface I5, a side cambered surface 6 and an inner concave cambered surface 7.

Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

Examples

Referring to fig. 1-3, the present invention provides a technical solution:

the utility model provides a floating oil seal convenient to installation, including floating seal seat 1, float seal ring 2, be equipped with rubber circle 3 between the two, one side at floating seal seat 1 and 3 contacts of rubber circle sets up interior conical surface I5, the one end of internal conical surface I5 sets up side cambered surface 6 simultaneously, correspond with rubber circle 3, make increase space between the two, easy to assemble, one side at floating seal ring 2 and 3 contacts of rubber circle sets up interior conical surface II 4, the one end of internal conical surface II 4 sets up indent cambered surface 7 simultaneously, correspond with rubber circle 3, can increase the space, easy to assemble.

As shown in fig. 2-3:

the radians of the side arc surface 6 and the inner concave arc surface 7 are both set to be pi/3 (60 degrees), so that the compressed rubber ring 3 can be adapted;

the rubber ring 3 made of the fluororubber material can improve the overall performance of the rubber ring 3, including heat resistance, oxidation resistance, oil resistance, corrosion resistance and the like.

The working principle is as follows: when specifically using, it needs to use in pairs to float seal ring 2, one is rotatory along with the rotating member (rotating ring), another relative static (stationary ring), between rotating ring and float seal seat 1 and at the stationary ring and float the conical surface between seal seat 1 (interior conical surface II 4 promptly, interior conical surface I5) department, respectively pack into a rubber circle 3 that has circular cross section, rubber circle 3 produces the deformation by axial compression in the sealed intracavity that floats seal seat 1 formation under the effect of assembly pretightning force, simultaneously because interior conical surface II 4 sets up indent cambered surface 7, interior conical surface I5 sets up side cambered surface 6 and can expand the space, consequently compare in traditional floating oil seal space enough when the installation, it is comparatively light to install.

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 utility model, the scope of which is defined in the appended claims and their equivalents.
