Description
Technical field
The invention belongs to field of sealing technology, it is adaptable to the sealing of electric locomotive gear box.
Background technology
With continuing to develop for China Express Railway technology, the sealing problem of electric locomotive gear box is outstanding day by day.Electric power
Installing locomotive gear cases are more to be run under high speed, severe duty, and the sealing difficulty of lubricating oil is larger.Electric locomotive gear box is close at present
Envelope is more using forms such as felt seal, oil sealing or labyrinth seals.Felt seal belongs to contact sealing, it is impossible to accomplish zero leakage, many
Used cooperatively with other seal forms；Oil sealing is sealed as one kind contact, is rubbed when high-speed overload is run larger, is produced larger
Heat, easily cause seal failure；Labyrinth seal can not accomplish zero leakage, in parking and startup stage, labyrinth seal it is close
Poor effect is sealed, and in the case of high-speed cruising, due to the lubricating oil in gear-box as temperature is raised, viscosity is gradually reduced,
Also easily lubricating oil is leaked along labyrinth channel.
The Leakage of electric locomotive gear box is to the machine in the service life and high-speed cruising of electric locomotive gear box
Car is pacified all with important influence, needs a kind of new seal form badly to solve the sealing problem of electric locomotive gear box.
The content of the invention
The technical problem to be solved in the invention：The problem of electric locomotive gear box oil leak.
The technical solution adopted for the present invention to solve the technical problems is：
A kind of magnetic liquid sealing structure for electric locomotive gear box, the structure includes：First felt ring, second mao
Felt ring (collar, the pole shoe of split-type first, the pole shoe of split-type second, split-type permanent magnet, snap ring, the non-magnetic set of split-type, magnetic liquid
Body.
Connection between the device each several part：
First felt ring and the second felt ring are arranged in the groove at the non-magnetic set two ends of split-type, the first felt ring peace
Mounted in gear-box close to one end of gear, for preventing the lubricating oil thrown away during gear operation close to split-type magnetic liquid
The direct impact of sealing assembly, the second felt ring is arranged on gear-box close to one end of wheel, for preventing in wheel operation process
Shock of the external particle to split-type magnetic fluid sealing component, then using snap ring by the first felt ring and the second felt ring edge
Circumferencial direction is fixed in the groove at the non-magnetic set two ends of split-type, afterwards by the pole shoe of split-type first and the pole shoe of split-type second
Adsorb respectively at the two ends of split-type permanent magnet, the pole shoe of split-type first, the pole shoe of split-type second, split-type permanent magnet are total to
Split-type magnetic fluid sealing component is arranged in the middle of the non-magnetic set of split-type by isomorphism into split-type magnetic fluid sealing component
Groove in and it is fixed, finally split-type structure is integrally spliced along end face, and magnetic liquid is injected into gear shaft and a point valve
In gap between the pole shoe of formula first, the pole shoe of split-type second, " O " type hydraulic seal circle is formed.
Beneficial effects of the present invention：
The magnetic liquid sealing structure that this kind is used for electric locomotive gear box is close by felt seal and split-type magnetic liquid
Envelope is combined, and gear-box internal lubrication oil and gear-box external particle are reduced to split-type magnetic liquid using felt seal
The impact of body seal assembly, while realizing the zero leakage of lubricating oil in gear-box using magnetic fluid sealing.
