Abstract

Asymmetric combination formula sealing structure full-complement cylinder roller bearing, including outer ring, inner ring, rolling element, sealing device, it is characterised in that：Rolling element is positioned between inner ring and outer ring, sealing device is provided between the Internal and external cycle of bearing side, the sealing device is labyrinth seal structure, labyrinth seal structure is made up of O-shaped seal assembly and movable back-up ring, O-shaped rubber seal is arranged on O-shaped rubber seal mounting, and movable back-up ring is provided with O-shaped sealing mounting side；Lip seal component is additionally provided between bearing opposite side Internal and external cycle.Internal and external cycle is asymmetric design, and sealing structure uses asymmetric double containment, adjustable bearings staring torque, and when end face applies preloading big, bearing staring torque becomes big, contributes to vehicle to adapt to various extreme landform road conditions and requires；Bearing internal external circle and movable back-up ring surface carry out coloring zinc processing, have extremely strong corrosion resistance, inoxidizability.

Description

Asymmetric combination formula sealing structure full-complement cylinder roller bearing
Technical field
The present invention relates to the wheel suspension bearing for heavy crawler or wheeled vehicle, asymmetric group is specifically related to Box-like sealing structure full-complement cylinder roller bearing, belongs to engineering machinery field.
Background technology
The high performances such as high static load, corrosion resistance are needed in the wheel suspension middle (center) bearing of heavy crawler or wheeled vehicle It is required that if do not possessed high performance requirements, then it can not meet all weather operations requirement of the vehicle under various harsh weather.
The content of the invention
In order to meet that vehicle suspension system bearing can be in all weather operations requirement under harsh weather, mesh of the invention Be to provide a kind of asymmetric combination formula sealing structure full-complement cylinder roller bearing.
To achieve these goals, the technical solution adopted in the present invention is：Asymmetric combination formula sealing structure completely fills circle Post roller bearing, including outer ring, inner ring, rolling element, sealing device, it is characterised in that：Rolling element be positioned over inner ring and outer ring it Between, it is provided with sealing device between the Internal and external cycle of bearing side, the sealing device is labyrinth seal structure, labyrinth sealing knot Structure is made up of O-shaped seal assembly and movable back-up ring, and O-shaped rubber seal is arranged on O-shaped rubber seal mounting, O-shaped close Envelope mounting side is provided with movable back-up ring；Lip seal component is additionally provided between bearing opposite side Internal and external cycle；
Described inner ring and outer ring are asymmetric structure；
Described bearing seal structure is sealed using double containment asymmetric combination formula；
Described movable back-up ring is Demountable；
The bearing inner race, outer ring and movable back-up ring are coloring zinc processing；
The beneficial effects of the invention are as follows：Internal and external cycle is asymmetric design, and sealing structure uses asymmetric double containment, adjustable Bearings staring torque, when end face applies preloading big, bearing staring torque becomes big, contributes to vehicle to adapt to various extreme landform roads Condition requirement；Bearing internal external circle and movable back-up ring surface carry out coloring zinc processing, have extremely strong corrosion resistance, inoxidizability.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
In figure, 1, outer ring, 2, inner ring 3, rolling element, 4, movable back-up ring, 5, lip seal component 6, O-shaped rubber seal Circle 7, O-ring sealing mounting.
Embodiment
The present invention is described in detail below in conjunction with the accompanying drawings.
Asymmetric combination formula sealing structure full-complement cylinder roller bearing, including outer ring 1, inner ring 2, rolling element 3, sealing dress Put, it is characterised in that：Rolling element 3 is positioned between inner ring 2 and outer ring 1, and sealing device is provided between the Internal and external cycle of bearing side, The sealing device is labyrinth seal structure, and labyrinth seal structure is made up of O-shaped seal assembly and movable back-up ring 4, O-shaped rubber Glue sealing ring 6 is arranged on O-shaped rubber seal mounting 7, and movable back-up ring 4 is provided with O-shaped sealing mounting 7 side；It is another in bearing Lip seal component 5 is additionally provided between the Internal and external cycle of side；
Described inner ring 2 and outer ring 1 are asymmetric structure；
Described bearing seal structure is sealed using double containment asymmetric combination formula；
The described bearing ring is asymmetric design, has unilateral detachable back-up ring that there is sealing to be developed simultaneously with dust reduction capability, interior Circle 2, outer ring 1 and the surface of movable back-up ring 4 carry out coloring zinc processing, have extremely strong corrosion-resistant, anti-oxidation characteristics.Bearing double-side Dissymmetrical structure is sealed into, side seals for more lip self-compensation types, and opposite side is " O-shaped " rubber ring crush seal.Residing for bearing Working condition requirement rotating speed is low, dead load is high, therefore uses and completely fill roller designs, Bearing inner filling lubricating grease self-lubricating.Bearing inner race, Outer ring is coloring zinc processing with movable back-up ring；Bearing can be effectively increased dead load ability to bear using completely dress roller designs；Axle Interior filling lubricating grease is held, there is self-lubricating property, bearing maintenance difficulty can be reduced.
