Abstract
The invention discloses a kind of two-way abutting formula marine screw shaft sealing devices, including stern tube shaft, connection end cap, connection ring flat-plate, sealing ring, axial elasticity body, radial elastomeric.The present invention compresses axially sealing ring by axial elasticity body, so that sealing ring is fitted tightly on the medial surface of connection end cap, sealing ring progress radial compression is fitted on stern tube shaft side by multiple radial elastomerics again, radial and axial has all obtained sealing performance so that of the invention.
Description
Technical field
The present invention relates to a kind of two-way abutting formula marine screw shaft sealing devices.
Background technique
Currently, marine screw shaft sealing device generally comprises stern tube shaft, end cover, sealing ring；The sealing ring is fastened on
On stern tube shaft, sealing ring compresses mechanism by elasticity and is connected on the medial surface of end cover, so seals stern tube shaft by sealing ring
And end cover, but in stern tube shaft long-term use process, stern tube shaft can be subjected to displacement axially, stern tube shaft will drive sealing ring progress
Displacement, so that the degree that compresses of sealing ring and end cover be made to change, causes sealing ring not have very well end cover
Sealing effect.
Summary of the invention
In view of the deficiencies of the prior art mentioned above, problems solved by the invention are as follows: provide a kind of sealing effect it is good one
The two-way abutting formula marine screw shaft sealing device of kind.
To solve the above problems, the technical solution adopted by the present invention is as follows:
A kind of two-way abutting formula marine screw shaft sealing device, including stern tube shaft, connection end cap, connection ring flat-plate, sealing ring, axial elasticity
Body, radial elastomeric；The connection end cap is mounted on the outside of one end surrounding of stern tube shaft；The connection ring flat-plate adapter sleeve connects peace
On the outside of the surrounding of stern tube shaft；The sealing ring is tightly sleeved on stern tube shaft；Axial elasticity body structure in a ring, axis
It is socketed on stern tube shaft to elastomer；The axial elasticity body is located between connection ring flat-plate and sealing ring；The axial elasticity
Body one end elasticity compresses an end face of sealing ring；The sealing ring other end is pressed on connection end cap medial surface；It is described
The outside of sealing ring multiple radial elastomerics are installed；Described radial elastomeric one end is fixed in connection end cap, radial bullet
The property body other end is pressed on the lateral surface of sealing ring.
Further, the outside of the sealing ring is equipped with annular mounting groove；The other end of multiple radial elastomerics
It is pressed in the annular mounting groove on the lateral surface of sealing ring.
Further, the sealing ring is made of rubber material.
Beneficial effects of the present invention
The present invention compresses axially sealing ring by axial elasticity body, so that sealing ring is fitted tightly over the interior of connection end cap
On side, then sealing ring is subjected to radial compression by multiple radial elastomerics and is fitted on stern tube shaft side, so that of the invention
It is radial and axial all to have obtained sealing performance.

Structure, axial elasticity body 3 are socketed on stern tube shaft 1 the axial elasticity body 3 stated in a ring；The axial elasticity body 3 is located at connection
Between ring flat-plate 2 and sealing ring 6；3 one end elasticity of axial elasticity body compresses an end face of sealing ring 6；The sealing ring 6
Other end is pressed on 4 medial surface of connection end cap；The outside of the sealing ring 6 is installed by multiple radial elastomerics 5；Described
5 one end of radial elastomeric is fixed in connection end cap 4, and 5 other end of radial elastomeric is pressed on the lateral surface of sealing ring 6.
As shown in Figure 1, further preferably, the outside of the sealing ring 6 is equipped with annular mounting groove 61；Multiple diameters
It is pressed on to the other end of elastomer 5 in the annular mounting groove 61 on the lateral surface of sealing ring 6.Further preferably, described close
Seal ring 6 is made of rubber material.
The present invention compresses axially sealing ring 6 by axial elasticity body 3, so that sealing ring 6 is fitted tightly over connection
On the medial surface of end cap 4, then sealing ring 6 is subjected to radial compression by multiple radial elastomerics 5 and is fitted on 1 side of stern tube shaft,
Radial and axial sealing performance has all been obtained so that of the invention.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Within mind and principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
