Abstract

A full-complement cylindrical roller bearing with an asymmetric combination type sealing structure comprises an outer ring, an inner ring, a rolling element and a sealing device, and is characterized in that the rolling element is arranged between the inner ring and the outer ring, the sealing device is arranged between the inner and outer rings on one side of the bearing and adopts a labyrinth sealing structure, the labyrinth sealing structure comprises an O-shaped sealing assembly and a movable check ring, an O-shaped rubber sealing ring is arranged on an O-shaped rubber sealing ring seat frame, and the movable check ring is arranged on one side of the O-shaped rubber sealing ring seat frame; a lip sealing assembly is further arranged between the inner and outer rings on the other side of the bearing. The inner ring and the outer ring adopts asymmetric design, the sealing structure adopts an asymmetric dual-sealing mode, the bearing start torque can be adjusted, when preload applied to the end surface is large, the bearing start torque becomes large, and a vehicle can meet requirements of various extreme terrain conditions; surfaces of the inner ring, the outer ring and the movable check ring of the bearing are subjected to colored galvanizing, and accordingly, the full-complement cylindrical roller bearing has very high corrosion resistance and oxidation resistance.

Description

Asymmetric combination formula sealing configuration full-complement cylinder roller bearing
Technical field
The present invention relates to the wheel suspension bearing for heavy crawler or wheeled vehicle, specifically relate to asymmetric combination formula sealing configuration full-complement cylinder roller bearing, belong to engineering machinery field.
Background technique
Needing the contour performance requirement of high static load, corrosion resistance at the wheel suspension middle (center) bearing of heavy crawler or wheeled vehicle, if do not possessed high performance requirements, then cannot meet all weather operations requirement of vehicle under various harsh weather.
Summary of the invention
Can all weather operations requirement under harsh weather in order to meet vehicle suspension system bearing, the object of this invention is to provide a kind of asymmetric combination formula sealing configuration full-complement cylinder roller bearing.
To achieve these goals, the technical solution adopted in the present invention is: asymmetric combination formula sealing configuration full-complement cylinder roller bearing, comprise outer ring, inner ring, rolling element, seal arrangement, it is characterized in that: rolling element is positioned between inner ring and outer ring, seal arrangement is provided with between the Internal and external cycle of bearing side, described seal arrangement is labyrinth seal structure, labyrinth seal structure is made up of O type black box and movable back-up ring, O type rubber seal is arranged on O type rubber seal mounting, is provided with movable back-up ring in O type sealing mounting side; Lip seal assembly is also provided with between bearing opposite side Internal and external cycle;
Described inner ring and outer ring are asymmetric structure;
Described bearing seal structure adopts the sealing of double-sealing asymmetric combination formula;
Described movable back-up ring is Demountable;
Described bearing inner race, outer ring and movable back-up ring are coloring zinc process;
The invention has the beneficial effects as follows: Internal and external cycle is asymmetric design, sealing configuration adopts asymmetric double-sealing, adjustable bearings starting torque, and when end face applies to preload large, bearing starting torque becomes large, contributes to vehicle and adapts to the requirement of various extreme landform road conditions; Coloring zinc process is carried out on bearing enclose and movable back-up ring surface, has extremely strong corrosion resistance, oxidative stability.
Accompanying drawing explanation
Fig. 1 is 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 assembly 6, O type rubber seal 7, O type circle sealing mounting.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described in detail.
Asymmetric combination formula sealing configuration full-complement cylinder roller bearing, comprise outer ring 1, inner ring 2, rolling element 3, seal arrangement, it is characterized in that: rolling element 3 is positioned between inner ring 2 and outer ring 1, between the Internal and external cycle of bearing side, be provided with seal arrangement, described seal arrangement is labyrinth seal structure, and labyrinth seal structure is made up of O type black box and movable back-up ring 4, O type rubber seal 6 is arranged on O type rubber seal mounting 7, is provided with movable back-up ring 4 in O type sealing mounting 7 side; Lip seal assembly 5 is also provided with between bearing opposite side Internal and external cycle;
Described inner ring 2 is asymmetric structure with outer ring 1;
Described bearing seal structure adopts the sealing of double-sealing asymmetric combination formula;
This bearing ring described is asymmetric design, and have one-sided detachable back-up ring to have sealing and develop simultaneously with dust reduction capability, coloring zinc process is carried out on inner ring 2, outer ring 1 and movable back-up ring 4 surface, has extremely strong corrosion-resistant, anti-oxidation characteristics.Bearing double-side is sealed into dissymmetrical structure, and side is the sealing of many lips self-compensation type, and opposite side is " O type " rubber ring crush seal.Residing for bearing, working condition requirement rotating speed is low, static load is high, therefore employing completely fills roller designs, the selflubricating of Bearing inner repack with grease.Bearing inner race, outer ring and movable back-up ring are coloring zinc process; Bearing adopts completely dress roller designs can effectively increase static load ability to bear; Repack with grease in bearing, has self-lubricating property, can reduce bearing maintenance difficulty.
