The invention discloses a kind of dynamic sealing device for ocean engineering power transmission sliding ring.The dynamic sealing device includes bearing, the first static seal, the second static seal, dynamic seal；The inner ring of the bearing, to upper overturning, is sealed by the first static seal between bearing outer ring and tumbler with outer ring, is sealed by the second static seal between bearing inner race and stationary apparatus, sealed between tumbler and stationary apparatus by dynamic seal；The dynamic seal is directly installed on bearing；With the axis side that dynamic seal coordinates using being heat-treated, case hardness is set to meet the requirement of dynamic seal.Bearing clearance precision higher of the present invention, therefore the radial disbalance smaller of dynamic seal when in use, so abrasion are evenly；Bearing can be conveniently heat-treated, and case hardness is reached dynamic seal with the use of requiring；Seal has the advantages that sealing performance is reliable, service life is long, cost is low and easy to operate without being installed in complete machine.
Description
Technical field
The present invention relates to electric power slip ring field, particularly a kind of dynamic sealing for ocean engineering power transmission sliding ring fills
Put.
Background technology
Most of existing slip ring is the form of inner air or internal filling with inert gas, therefore is asked without the concern for oil leak
Topic.Chinese patent CN 206322976U (applying date 2016.07.29) disclose a kind of electric power for single point mooring system and slide
Loop device, the electric power slip-ring device have a high voltage power transmission slip ring, and high voltage power transmission slip ring includes central shaft, stator, rotor, contact
Module and shell body, are arranged to stator on the excircle of central shaft, rotor, conductive contact are arranged between conducting ring and shell body
Component is contact modules.Shell body and conducting ring are fixed part, and center roller is rotating part, and conducting ring passes through with rotor
Contact modules, which are realized, to be relatively rotated, and slip ring unitary rotation is realized by slip ring upper/lower terminal bearing；And the slip ring include oil inlet with
Oil outlet, methods for cooling use immersion oil mode.This above-mentioned slip ring transmits high-voltage great-current due to needing to meet under specific dimensions
Requirement, it is therefore necessary to use internal immersion oil form.
But slip-ring rotor rotated by bearing during there may be problems with：1) with supporting dynamic close of bearing
The radial disbalance of sealing when in use is larger, serious wear；2) dynamic seal is high to the hardness requirement of matching sympodium side, and there are dynamic
Seal gnaws the phenomenon of metal surface；3) dynamic seal need to be installed in complete machine, therefore installing and dismounting is cumbersome.
The content of the invention
It is an object of the invention to provide a kind of sealing performance is reliable, service life is long, cost is low and easy to operate use
The dynamic sealing device of Yu Haiyang engineering power transmission sliding ring.
The technical solution for realizing the object of the invention is：A kind of dynamic sealing device for ocean engineering power transmission sliding ring,
Including bearing, the first static seal, the second static seal, dynamic seal；
The inner ring of the dynamic sealing device bearing and outer ring are to upper overturning, by the between bearing outer ring and tumbler
One static seal seals, and is sealed between bearing inner race and stationary apparatus by static seal, between tumbler and stationary apparatus
Sealed by dynamic seal.
Further, the dynamic seal is directly installed on bearing.
Further, case hardness is made to meet the use of dynamic seal using being heat-treated with the axis side that dynamic seal coordinates
It is required that.
Compared with prior art, the present invention its remarkable advantage is：(1) bearing clearance precision higher, therefore dynamic seal exists
Radial disbalance smaller during use, abrasion is evenly；(2) good airproof performance, the dynamic seal of long lifespan are to the hard of matching sympodium side
Degree requires higher, and bearing, which carries out heat treatment, makes case hardness reach dynamic seal with the use of requiring, in order to avoid there is dynamic seal
Gnaw the phenomenon of metal surface；(3) seal is in complete machine without installing, have sealing performance is more reliable, service life is longer,
The advantages of cost is lower and easy to operate.
Brief description of the drawings
Fig. 1 is the structure chart for the dynamic sealing device that the present invention is used for ocean engineering power transmission sliding ring.
Embodiment
With reference to Fig. 1, the present invention is used for the dynamic sealing device of ocean engineering power transmission sliding ring, it is turned by the sealing on bearing
Change, reached the use condition for not only meeting spring energy-storage polytetrafluoroethylene (PTFE) dynamic sealing, but also can easily integrally install, including bearing
1st, the first static seal 2, the second static seal 3, dynamic seal 4；
The inner ring of the dynamic sealing device bearing 1, to upper overturning, passes through with outer ring between 1 outer ring of bearing and tumbler
First static seal 2 seals, and is sealed between 1 inner ring of bearing and stationary apparatus by static seal 3, tumbler and stationary apparatus
Between sealed by dynamic seal 4.
As a kind of specific example, the dynamic seal 4 is directly installed on bearing 1, at the convenient heat of bearing material
Reason, hardness are high, realize the use condition of spring energy-storage polytetrafluoroethylene (PTFE) dynamic sealing.
As a kind of specific example, with the axis side that dynamic seal 4 coordinates using being heat-treated, case hardness is set to meet dynamic sealing
The requirement of part 4.
Above-mentioned form has the advantage that：1. bearing clearance precision higher, therefore the radial disbalance of dynamic seal when in use
Smaller, so abrasion are evenly；2. general good airproof performance, the dynamic seal of long lifespan to the hardness requirement of matching sympodium side more
Height, in order to avoid there is the phenomenon that dynamic seal gnaws metal surface, and bearing can be conveniently heat-treated, and reach case hardness
Dynamic seal is used cooperatively and requires；3. seal need not be installed in complete machine, therefore easy for assemble or unload.Therefore it is high performance dynamic
This combining form of seal and bearing is with sealing performance is more reliable, service life is longer, cost is lower and easy to operate
The advantages of.
