Description
Technical field
The present invention relates to a kind of bearing, relate in particular to a kind of nonstandard thin-walled water-sealed bearing.
Background technique
In the prior art, bearing generally all comprises seal ring, outer ring, nylon cages, steel ball and inner ring, and mainly there is following shortcoming in it: the width of outer ring and inner ring is identical, and needs the processing seal groove on the outer ring, also wants the fitting tight circle in addition; The ditch position that is used for fixing steel ball on the inner ring is in the center, and the outer ring is not inclined to one side relatively; The bottom surface height of nylon cages receives the seal space position limit, and this distortion and intensity to the nylon cages of thin-wall product is very disadvantageous.
Summary of the invention
The object of the present invention is to provide a kind of mode of execution of nonstandard thin-walled water-sealed bearing, can solve the existing bearing preponderance, the problem that cost is too high and difficulty of processing is big with expectation.
For addressing the above problem, the technological scheme that the present invention taked is:
A kind of nonstandard thin-walled water-sealed bearing; Comprise outer ring, inner ring, steel ball and nylon cages; Described steel ball is arranged between outer ring and the inner ring through nylon cages; The middle inside of said outer ring is provided with the outer gutter suitable with steel ball, and the outside of said inner ring is provided with the inclined to one side ditch suitable with steel ball, and said inclined to one side ditch is positioned at the outside eccentric part of inner ring; Said inner ring has one section portion that deflects away from that deflects away from outer ring one side when matching with the outer ring, the said outer diametric plane that deflects away from portion forms the interference fit that contacts with water-tight rubber ring on the main frame that uses this bearing.
For making the present invention play better technique effect:
Technological scheme further is that the width of above-mentioned outer ring is 3～4mm.
Technological scheme further is that the thickness of above-mentioned outer ring is 0.9315～0.9515mm.
Technological scheme further is that the ditch coefficient of curvature of above-mentioned outer ring is 0.512～0.525.
Technological scheme further is that the width of above-mentioned inner ring is 6.1～6.3mm.
Technological scheme further is that the thickness of above-mentioned inner ring is 1.19～1.21mm.
Technological scheme further is that the ditch coefficient of curvature of above-mentioned inner ring is 0.512～0.525.
Technological scheme further is that the external diameter surface roughness of the portion that deflects away from of above-mentioned inner ring is≤0.25 μ m.
Technological scheme further is the outside eccentric part that above-mentioned inclined to one side ditch is positioned at inner ring, and its eccentric distance is 1.45 ± 0.03mm.
Technological scheme further is that the height that is positioned at the steel ball bottom surface of above-mentioned nylon cages is 0.55～0.75mm.
Adopt the beneficial effect that technique scheme produced to be: because a kind of nonstandard thin-walled water-sealed bearing of the present invention is without the seal groove of installation and processing seal ring, and no longer installs seal ring, make the present invention on weight than traditional design bearing light 15～25%; In addition, because the minimizing of the manufacturing procedure of outer ring and inner ring, and no longer need process seal groove and seal ring is installed, cost of production and difficulty of processing reduce than traditional bearing greatly, and using effect has also obtained effective raising.
