Abstract

The utility model provides a kind of water-sealed bearing, including outer ring, inner ring, rolling element and retainer, it is characterized in that, also include the sealed cover slip of ring-type disc type, step is equipped with the end face of outer ring two, the periphery at inner ring two ends is provided with annular slot, and the interior nose circle of sealed cover slip is stuck in the neck of inner ring, and outer nose circle is resisted against on the end face of outer ring.Its effect is：Water resistance is good, can effectively prevent water and impurity from entering bearing cavity, improves the service life of bearing, and can normal table operation, elimination failure.

Description

Water-sealed bearing

Technical field：The utility model is related to the rolling bearing that a kind of mechanical field is used, particularly a kind of water-proof function Strong water-sealed bearing.

Background technology：Existing rolling bearing is mainly made up of outer ring, inner ring, rolling element and the part of retainer four；It is used On the Work machines such as various lathes, motor, water pump.In use, existing rolling bearing exist a deficiency is, water proofing property compared with Difference, this often to be immersed in water inside bearing outdoor, under water, in the environment work such as humidity machinery in operation its, or In the mixture of water and impurity, this not only easily makes bearing easily get rusty reduction service life, and can often occur bearing be blocked or Situation about blocking occurs, and causes plant running not normal or leads to a disaster.

The content of the invention：The purpose of this utility model is, for the existing water proofing property existed in use in rolling bearing Can be poor, easily get rusty and be easily caused the deficiency that bearing service life shortens or damaged, and propose that a kind of water resistance is strong, service life Long, operate steadily reliable water-sealed bearing.

The utility model purpose, a kind of water-sealed bearing, including outer ring, inner ring, rolling can be realized by following technical proposals Body and retainer, it is characterised in that also include being equipped with step in the sealed cover slip of ring-type disc type, the end face of outer ring two, The periphery at inner ring two ends is provided with annular slot, and the interior nose circle of sealed cover slip is stuck in the neck of inner ring, and outer nose circle is resisted against On the end face of outer ring.

For ease of installing, the external diameter of sealed cover slip, less than the external diameter of outer ring step end face, more than in the step end face of outer ring Footpath.

To improve water resistance, the roughness of the end face of outer ring inner ring step is not more than Ra0.4um.

For the benefit of water resistance, the thickness of sealed cover slip is 0.10~0.2mm, sealed cover slip and outer ring inner ring step end face Contact surface be plane, its roughness is not more than Ra0.4um.

Effect of the present utility model is：Water resistance is good, can effectively prevent water and impurity from entering bearing cavity, improves The service life of bearing, and can normal table operation, elimination failure.This is, this bearing on the basis of existing bearing, Add the sealed cover slip of ring-type disc type and outer ring and inner ring are correspondingly improved；The inner circle side end of sealed cover slip is led to In the annular slot for crossing certain pressure press-in inner ring, outer rim side end is flatted against on the step end face of outer ring, because of sealing Cover plate is relatively thin and has certain elasticity, and its outer rim side end can be with outer ring step end face tight abutment, so that sealed cover slip can be right Bearing cavity one good sealing of formation, reaches the good waterproof effect of the present apparatus one.

Below in conjunction with the accompanying drawings and the utility model is expanded on further embodiment：

Brief description of the drawings：

Accompanying drawing 1 is the utility model section structure schematic diagram；

Accompanying drawing 2 is the floor map of sealed cover slip in the utility model；

Accompanying drawing 3 is sectional view at A~A in accompanying drawing 2.

Embodiment：

Referring to accompanying drawing 1,2,3, a kind of water-sealed bearing, it is mainly by outer ring 1, inner ring 2, rolling element 3, retainer 4, closure Piece 5 is constituted.Step is equipped with the end face of outer ring 1 two, the roughness of step end face is not more than Ra0.4um.The two ends of inner ring 2 Annular slot is set on outer circumference surface.Sealed cover slip 5 is ring-type disc type, and its material is equipped with bearing making material, its thickness For 0.10~0.2mm, the contact surface of itself and the step end face of outer ring 1 is plane, and its roughness is not more than Ra0.4um.Sealed cover slip 5 Interior nose circle be stuck in the neck of inner ring 2, outer nose circle is resisted against on the step end face of outer ring 1.For ease of installing, sealed cover slip 5 External diameter be less than step end face external diameter, more than the internal diameter of step end face.The internal diameter of sealed cover slip 5 is slightly less than the external diameter of inner ring 2.
