Abstract
The utility model discloses a three seal structure on spindle bearing, spindle axle contracting draws together the seat circle, the blowout patche, the roller, the housing, two O type sealing washers and a reinforced seal circle, installation a plurality of roller between seat circle and the blowout patche, thereby the outside of present circle of housing cover and blowout patche is with the seat circle, the blowout patche, the roller installation together, reinforced seal circle of installation between the outer disc of seat circle and the housing, O type sealing washer of hole installation of seat circle, a O type sealing washer is also installed to the hole of blowout patche, three sealing washer constitutes three seal structure, three seal structure and king bdt constitute an inclosed space, effectively prevent inside the xenembole bearing. The beneficial effects of the utility model are that, the cooperation of labyrinth rubber reinforced seal circle and housing, prevent the xenembole bearing inside, two O type sealing washers form the enclosed cavity with king bdt, prevent that the foreign matter from getting into the bearing from the gap between bearing bore diameter and the king pin to the oil gas leakage has been improved.
Description
Technical field
The utility model belongs to free bearing field, relates to a kind of motor turning bearings three sealing configuration.
Background technique
Along with the development of bearing industry, the sealing configuration of motor turning bearings has a very large change, and being sealed to from the case of bearing increases seal ring sealing, is sealed to backbone sealing ring sealing from O type circle.Along with the progress of society, expanding economy, automobile industry and the motor turning bearings demand of user vehicle to long lifetime, good airproof performance increase day by day, are only seal can not satisfy the demands, and how to improve the direction that sealability is Company's research.
Summary of the invention
The utility model, in order to make up the deficiencies in the prior art, provides that a kind of structure is simple, easy to use, motor turning bearings three sealing configuration of good sealing effect.
The utility model is achieved by the following technical solution:
Motor turning bearings three sealing configuration of the present utility model, it is characterized in that: motor turning bearings comprises seat ring, blowout patche, roller, case, two O RunddichtringOs and a backbone sealing ring, several rollers are installed between seat ring and blowout patche, case be enclosed within seat ring and blowout patche outside thus by seat ring, blowout patche, roller is installed together, a backbone sealing ring is installed between the periphery of seat ring and case, the endoporus of seat ring installs an O RunddichtringO, the endoporus of blowout patche also installs an O RunddichtringO, three seal rings form three sealing configurations, three sealing configurations and king bdt form an airtight space, effectively prevent foreign matter from invading Bearing inner.
Backbone sealing ring and O RunddichtringO are made up of oil resistant nitrile rubber.
The beneficial effects of the utility model are, structure is simple, easy to use, good sealing effect, mazy type rubber skeleton seal ring coordinates with case, prevent foreign matter from invading Bearing inner, two O RunddichtringOs and king bdt form enclosed cavity, can prevent foreign matter from entering bearing from the gap between bearing bore diameter and king pin, and effectively improve oil and gas leakage.Nitrile rubber has splendid anticorrosive, tear-proof and incompressible deformation characteristic, effectively improves the sealing effect of bearing.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, 01 seat ring, 02 blowout patche, 03 king bdt, 04 roller, 93 cases, 09 backbone sealing ring, 68O RunddichtringO.
Embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.
Motor turning bearings three sealing configuration of the present utility model, motor turning bearings comprises seat ring 01, blowout patche 02, roller 04, case 93, backbone sealing ring 09 and two O RunddichtringOs 68, several rollers are installed between seat ring and blowout patche, case be enclosed within seat ring and blowout patche outside thus by seat ring, blowout patche, roller is installed together, mounting framework seal ring between the periphery of seat ring and case, the endoporus of seat ring installs an O RunddichtringO, the endoporus of blowout patche also installs an O RunddichtringO, a backbone sealing ring and two O RunddichtringOs form three sealing configurations, three sealing configurations and king bdt form an airtight space.
Backbone sealing ring and two O RunddichtringOs form by oil resistant nitrile rubber is refining.
Free bearing is installed to after on spindle, a backbone sealing ring 09 and two O RunddichtringOs 68 form three sealing configurations, a backbone sealing ring and two O RunddichtringOs and king bdt 03 form an airtight space, effectively prevent foreign matter from invading Bearing inner.
Mazy type rubber skeleton seal ring coordinates with case, prevent foreign matter from invading Bearing inner, two O RunddichtringOs and king bdt form enclosed cavity, can prevent foreign matter from entering bearing from the gap between bearing bore diameter and king pin, and effectively improve oil and gas leakage.Nitrile rubber has splendid anticorrosive, tear-proof and incompressible deformation characteristic, effectively improves the sealing effect of bearing.
