Description
Technical field
The present invention relates to a kind of passenger train axlebox assemblies, more specifically, are related to a kind of passenger train of four resealings
Axlebox assemblies.
Background technology
Existing passenger train axlebox assemblies encapsulation scheme is single metal labyrinth sealing or felt seal.Single gold
Category labyrinth sealing performance is general, and seal can be preferably bonded radial and axial, but laminating degree is limited by adding for seal
The size of work error and seal clearance, once seal clearance is excessive, outside contamination can be invaded inside axle box, make internal bearings because by
Normal use is influenceed to pollution.Single felt seal is simple in construction, it is contemplated that influenceed by a variety of environmental factors, therefore it is suitable
Not strong with property, friction is larger, and sealing effectiveness is general.
The content of the invention
It is an object of the invention to provide a kind of passenger train axlebox assemblies of four resealings, to solve existing railway passenger axletree
Above mentioned problem existing for box assembly sealing, the axlebox assemblies are simple in construction, and sealing effectiveness is superior, improve passenger train axle box
Service life.
The purpose of the present invention is achieved through the following technical solutions：
A kind of passenger train axlebox assemblies of four resealings, including axle box bearing, packing ring, axle box, journal box rear cover, seal assembly
And other axlebox assemblies, it is characterised in that：
The axle box bearing is the Biserial cylindrical roller bearing with retainer, and bearing outer ring is integral type structure, outside bearing outer ring
Low friction seal is installed close to one groove of place processing of end in surface.Double-row cylindrical roller is respectively by the first retainer,
Two retainers are separated, and by having rib inner ring and being formed without rib inner ring, no rib inner ring is carried out bearing inner race by movable back-up ring
Axially position.
The low friction seal is made up of steel low friction seal body and rubber low friction seal sealing lip.
The packing ring is stepped packing ring, abuts against axle box wheel shaft, and packing ring left upper part point is machined with labyrinth projection, right-hand member
End face abuts bearing outer ring end face, carries out axially position.The contact area of the packing ring right-hand member end face and bearing outer ring end face is
Cementation zone, frictional influence caused by reduce shearing force.
The packing ring right-hand member upper part is provided with gasket seal, and the gasket seal material is stamped steel.
The axle box and the journal box rear cover binding face are sealed by O-ring, prevent environmental contaminants by binding face
Enter in gap inside axle box.

Axially position is carried out, and is bolted with axle box end.
Other described axlebox assemblies include journal box front cover, baffle plate, baffle plate bolt, check washer.
The labyrinth groove and labyrinth male cooperation of the journal box rear cover and the packing ring form labyrinth seal, form the first weight
Sealing.
The journal box rear cover and the packing ring carry out supplement sealing by V annular seals, and V rings opening is used for towards outside
Resistance contaminant ingression as caused by failing the first resealing, forms the second resealing.
The planar section of the gasket seal is cementation zone, contacts to be formed with the low friction seal sealing lip
Lip seal, form triple seal.
The low friction seal and the slit in bearing inner race lip-guided face form the 4th resealing.
First weight and the second resealing are to external seal, it is therefore an objective to environmental contaminants are resisted, such as dust, particle and wet
Gas, into inside axle box, insufficient lubrication, effect of attrition are produced to axle box, especially axle box bearing.
The triple and quadruple is sealed into interior sealing, it is therefore an objective to prevents Bearing inner lubricant grease from leaking, pollution
Inside axle box.
It is contemplated that axle box wheel with greater curvature to entering walking along the street during the passenger train axial component design of four resealing
Footpath is turned round or when uneven road surface travels, and Bearing inner may be caused by causing cylinder roller bearing that a small amount of internal axial displacement occurs
The problem of lubricating grease is revealed, in of the invention, low friction seal and gasket seal positioned at axle box bearing outer ring outer surface begin
Contact with each other eventually, keep not released state, avoid lubricant grease and leak into outside axle box.
The axle box bearing outer ring outer surface is symmetrically installed the second low friction seal, the second low friction seal by
Steel the second low friction seal body and rubber the second low friction seal sealing lip are formed.
The baffle plate external peripheral surface is provided with baffle seal, and the baffle seal material is stamped steel, and described
The contact of second low friction seal sealing lip forms contact lip seal, prevents Bearing inner lubricant grease from leaking into outside axle box
Portion.
The movable back-up ring carries out axially position, the second low friction seal and active catch to axle box bearing without rib inner ring
The slit for enclosing guide surface forms slit sealing.
The bearing protecgulum is connected with axle box end longitudinal direction faying face by connecting bolt, horizontal integration face installation second
O-ring, sealing are anti-pollution.
The baffle plate shoulder protrusion abuts movable back-up ring, and end abuts axle box axle ends, and passes through baffle plate bolt connection.
To prevent bolt from skidding, check washer is disposed between bolt nut and baffle plate.
