a fastening and sealing structure of vibration equipment comprises a sealing gasket body, wherein a radial sealing groove is formed in the middle of an inner hole of the sealing gasket body, and a plane sealing groove is formed in the front end face of the sealing gasket body; and a radial sealing ring is embedded in the radial sealing groove, and a plane sealing ring is embedded in the plane sealing groove.
The radial sealing ring and the plane sealing ring are both oil-resistant nitrile rubber or fluororubber.
The sealing gasket body is a wear-resistant alloy part with the surface hardness of 36-42 HRC.
The rear end face of the sealing gasket body is provided with a spring ring, and the sealing gasket body and the spring ring are designed into an integral structure.
The diameter of the outer circle of the sealing gasket body is at least one time of the diameter of the inner hole.
Compared with the prior art, the utility model discloses a fastening sealing structure of vibration equipment, which comprises a sealing gasket body, wherein the middle part of an inner hole of the sealing gasket body is provided with a radial sealing groove, and the front end surface is provided with a plane sealing groove; and a radial sealing ring is embedded in the radial sealing groove, and a plane sealing ring is embedded in the plane sealing groove. During the use, with seal gasket body suit on the bolt, the bolt passes in proper order and treats the connecting piece to with the plane sealing washer butt of seal gasket body front end face on the connecting piece, realize plane seal through plane sealing washer, radial sealing washer realizes axial seal simultaneously, through two-stage seal, guarantees under the abominable operating mode of continuous vibrations, connects firmly, the leakproofness is good.
The utility model has the advantages that:
the utility model discloses simple structure, low cost, the simple operation nature is high, and the connection reliability is high, and the leakproofness is good, is particularly useful for the equipment rigid connection position of vibrations in succession, and it is sealed through the two-stage, and elasticity locking in addition guarantees that joint strength and reliability are high, and the leakproofness is good, and long service life reduces the later stage and changes and the maintenance cost moreover, and the practicality is good.
Additional advantages, objects, and features of the invention will be set forth in part in the description which follows and in part will become apparent to those having ordinary skill in the art upon examination of the following or may be learned from practice of the invention. The objectives and other advantages of the invention may be realized and attained by the means of the instrumentalities and/or combinations particularly pointed out in the appended claims.

Detailed Description
Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be understood that the preferred embodiments are for purposes of illustration only and are not intended to limit the scope of the present invention.
As shown in fig. 1-5, a fastening and sealing structure of a vibrating device includes a sealing gasket body 1, a radial sealing groove 101 is provided in the middle of an inner hole of the sealing gasket body 1, and a plane sealing groove 102 is provided on a front end surface; a radial seal ring 2 is embedded in the radial seal groove 101, and a planar seal ring 3 is embedded in the planar seal groove 102.
The radial sealing ring 2 and the plane sealing ring 3 are both oil-resistant nitrile rubber or fluororubber.
The sealing gasket body 1 is a wear-resistant alloy part with the surface hardness of 36-42HRC, and the service life is long.
Preferably, be equipped with spring coil 103 at seal gasket body 1 rear end face, connect more firmly in the vibrations environment for guaranteeing, the leakproofness is better.
