For achieving the above object, the utility model provides following technological scheme: a kind of waterproof sealing bearing, comprise inner ring, outer ring, retainer and be located at inner ring and outer ring between steel ball, one side of described steel ball is provided with the first waterproof sealing structure, described waterproof sealing structure comprises the bellows with the coaxial setting of inside and outside circle, and described bellows is located between inner ring and outer ring;
Described inner ring is fixedly connected with steel loop near a side of retainer, the one side of the relative inner ring in described outer ring is provided with outer groove, described outer groove is positioned at a described steel loop side of retainer dorsad, described outer groove comprises outer side wall, madial wall and bottom surface, one end of described bellows is fixedly connected on steel loop, and the other end of described bellows is conflicted and is connected with seal ring;
Described outer side wall is provided with the seal groove embedding for seal ring, and described seal ring dorsad one end of bellows is embedded in described seal groove;
The opposite side of described steel ball is provided with the second waterproof sealing structure with the first waterproof sealing structure same structure.
By adopting technique scheme, first, second waterproof sealing structure of same structure is set in described steel ball both sides, can utilize described bellows to there is the feature of axial elasticity, order about seal ring and tightly embed described seal groove, realize sealing; And, in the time running into the underwater environment of high pressure, in the time that bellows is subject to high pressure, axial extension can occur, then promotes described inclined-plane and be tight against seal groove, hyperbaric environment realizes sealing under water, practical.
The utility model is further set to: the axial cross section of described two seal rings is trapezium structure, and the outer peripheral surface of described two seal rings is along bellows separately to seal groove direction, tilt from outer ring toward inner ring direction.
By adopting technique scheme, by the outer peripheral surface of described two seal rings along bellows separately to seal groove direction, tilt from outer ring toward inner ring direction, can utilize described inclined-plane, in the time that pressure is higher, the sealing of described seal ring is tightr, and, in the time that bearing inner race rotates at a high speed, drive and order about described seal ring to there is certain centrifugal force, thereby and conflict between bearing outer ring also tightr.
The utility model is further set to: the one side of described two relative outer rings of bellows is all arranged with some fixed steelrings.
By adopt technique scheme, sheathed steel ring, can utilize described steel ring prevent bellows in the time being under pressure, produce radially deformation, ensure the working life of described bellows.
The utility model is further set to: the surface of described two seal rings and the surface of described two seal grooves are all coated with Teflon material.
By adopting technique scheme, all be coated with Teflon material on the surface of described two seal rings and the surface of described two seal grooves, can utilize the sliding of described Teflon material, friction when reducing described seal ring and seal groove and conflicting, thereby suffered load while reducing described bearing working.
