The invention discloses a kind of cup type Sheng oil structures of oil-immersed type slip ring.The structure includes pedestal, outer barrel, dynamic lid, static seal, the first dynamic seal, the second dynamic seal, clutch shaft bearing, second bearing, 3rd bearing, slip ring outer shroud, slip ring inner ring；The pedestal, slip ring inner ring, slip ring outer shroud, outer barrel are sequentially arranged from the inside to the outside, and wherein outer barrel is fixedly connected with base bottom, and pedestal, the top of outer barrel are connected respectively by clutch shaft bearing, second bearing and dynamic lid；Dynamic lid is fixedly connected with slip ring outer shroud, and pedestal is fixedly connected with slip ring inner ring；Slip ring outer shroud is mounted on the bottom of pedestal by 3rd bearing；Pedestal, outer barrel bottom between sealed by static seal, pass through the first dynamic seal respectively between pedestal, the top of outer barrel and dynamic lid, the second dynamic seal seals.For the present invention since slip ring dynamic sealing is entirely at top, bottom is static seal, therefore it is more preferable to contain oil sealing effect.
Description
Technical field
The present invention relates to the cup type Sheng oil structures in oil-immersed type slip ring field, particularly a kind of oil-immersed type slip ring.
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 outer housing are arranged to stator on the excircle of central shaft, rotor, conductive contact are arranged between conducting ring and outer housing
Component is contact modules.Outer housing 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 transfers high-voltage great-current due to needing to meet under specific dimensions
Requirement, it is therefore necessary to use internal immersion oil form.
But the form that the structure type of existing slip ring is upper and lower dynamic sealing, so if keeping the basic of existing slip ring
Structure type is constant, only simple inside oiling, then there are dynamic sealing can cause slip ring in permanent worker due to slip ring bottom
Easy oil leak under work.
The content of the invention
It is an object of the invention to provide a kind of cup type Sheng oil structures for the oil-immersed type slip ring that can avoid oil leak.
Realize the object of the invention technical solution be：A kind of cup type Sheng oil structure of oil-immersed type slip ring, including pedestal,
Outer barrel, dynamic lid, static seal, the first dynamic seal, the second dynamic seal, clutch shaft bearing, second bearing, 3rd bearing, slip ring
Outer shroud, slip ring inner ring；
The pedestal, slip ring inner ring, slip ring outer shroud, outer barrel are sequentially arranged from the inside to the outside, and wherein outer barrel is consolidated with base bottom
Fixed connection, pedestal, the top of outer barrel are connected respectively by clutch shaft bearing, second bearing and dynamic lid；Dynamic lid is fixed with slip ring outer shroud
Connection, pedestal are fixedly connected with slip ring inner ring；Slip ring outer shroud is mounted on the bottom of pedestal by 3rd bearing；Pedestal, outer barrel
It is sealed by static seal between bottom, is moved respectively by the first dynamic seal, second between pedestal, the top of outer barrel and dynamic lid
Sealing element seals.
Further, the pedestal includes central shaft and pedestal, and the two is fixedly connected.
Further, first dynamic seal is mounted on clutch shaft bearing, and clutch shaft bearing is mounted in slip ring inner ring.
Further, second dynamic seal is mounted in second bearing, and second bearing is mounted on supporting rack.
Compared with prior art, the present invention its remarkable advantage is：(1) by dynamic sealing at two all as top, therefore bottom
Without oil leak, oil leak hidden danger is small, and it is more reliable to contain oil in portion；(2) since slip ring dynamic sealing is entirely at top, bottom is static seal, static seal
Sealing effect be better than dynamic sealing and static seal longer life expectancy.
Description of the drawings
Fig. 1 is the cup type Sheng oil structure diagram of oil-immersed type slip ring of the present invention.
Fig. 2 be oil-immersed type slip ring of the present invention cup type Sheng oil structure in pedestal structure diagram.
Fig. 3 be oil-immersed type slip ring of the present invention cup type Sheng oil structure in outer barrel structure diagram.
Fig. 4 is the structure diagram that lid is moved in the cup type Sheng oil structure of oil-immersed type slip ring of the present invention.
Specific embodiment
Fill oil inside oil-immersed type slip ring, outer shroud rotates during work, and inner ring is fixed.Electric current is realized defeated from top by outer shroud
Enter, reach inner ring by brush realizes output from bottom again.To ensure that Sheng oil seal is reliable inside slip ring, devises immersion oil of the present invention
The cup type Sheng oil structure of formula slip ring, it is specific as follows with reference to Fig. 1~4：Including pedestal 1, outer barrel 2, dynamic lid 3, static seal 4, first
Dynamic seal 5, the second dynamic seal 6, clutch shaft bearing 7, second bearing 8,3rd bearing 9, slip ring outer shroud 10, slip ring inner ring 11；
The pedestal 1, slip ring inner ring 11, slip ring outer shroud 10, outer barrel 2 are sequentially arranged from the inside to the outside, and wherein outer barrel 2 is consolidated with 1 bottom of pedestal
Fixed connection, pedestal 1, the top of outer barrel 2 are connected respectively by clutch shaft bearing 7, second bearing 8 with dynamic lid 3；Outside dynamic lid 3 and slip ring
Ring 10 is fixedly connected, and pedestal 1 is fixedly connected with slip ring inner ring 11；Slip ring outer shroud 10 is mounted on the bottom of pedestal 1 by 3rd bearing 9
Portion；Pedestal 1, outer barrel 2 bottom between sealed by static seal 4, lead to respectively between pedestal 1, the top of outer barrel 2 and dynamic lid 3
Cross the first dynamic seal 5, the second dynamic seal 6 seals.
As shown in Fig. 2, the pedestal 1 includes central shaft and pedestal, the two is fixedly connected.
As a kind of specific example, first dynamic seal 5 is mounted on clutch shaft bearing 7, and clutch shaft bearing 7, which is mounted on, to be slided
In ring inner ring 11.
As a kind of specific example, second dynamic seal 6 is mounted in second bearing 8, and second bearing 8 is mounted on branch
On support.
With reference to Fig. 1~4, the cup type Sheng oil structure of oil-immersed type slip ring of the present invention, erection sequence is：
