Abstract
The utility model relates to a multi-deck centroclinal ball bearing. Compared with the existing centripetal ball bearings, the utility model is characterized in that a middle ring is added between the inner and outer rings of the multi-deck centroclinal ball bearing, roller balls are arranged between the inner ring and the middle ring, and roller balls are arranged between the outer ring and the middle ring. The possibility of counter rotation between the inner ring and the outer ring of the utility model can be increased, thus the multi-deck centroclinal ball bearing is suitable for high speed operation.
Description
The utility model belongs to a kind of centripetal ball bearing.
At present used centripetal ball bearing is equipped with ball and ball retainer and is constituted by the inside and outside circle of bearing between bearing enclose.
Such bearing generates heat when running up easily, and therefore the wearing and tearing aggravation is easy to damage, and the life-span is short.
The utility model provides a kind of centripetal ball bearing that is suitable for running up.
The utility model is achieved in that and adds mesosphere between the inside and outside circle of bearing:
When adding a mesosphere, ball and ball retainer are housed between bearing inner race and the mesosphere, ball and ball retainer are housed between bearing outer ring and the mesosphere, form two course heart ball bearings.
When adding two mesospheres, ground of cover of two mesospheres is arranged, at this moment between bearing inner race and the little mesosphere ball and ball retainer are housed, be equipped with between little mesosphere and the big mesosphere between ball and ball retainer, big mesosphere and the bearing outer ring ball and ball retainer are housed, form three course heart ball bearings.
In two course heart ball bearings, can form between bearing inner race and the mesosphere and relatively rotate, relatively rotate and can form between mesosphere and the bearing outer ring, so just increased in the bearing possibility of running relatively between the outer ring.Compare with existing centripetal ball bearing, under the same rotating speed, the motion of the ball of this two course heart ball bearings is slower, so bearing life is long, and this bearing can adapt to and runs up.As a same reason, three course heart ball bearings can adapt to higher rotating speed.
Further specify below in conjunction with embodiment and structural representation thereof.
Fig. 1 is the structural representation of biserial two course heart ball bearings.
Fig. 2 is the structural representation of biserial three course heart ball bearings.
In Fig. 1, the 1st, bearing outer ring, the 2nd, mesosphere, the 3rd, bearing inner race, the 4th, ball, the 5th, ball retainer.
In Fig. 2, the 1st, bearing outer ring, the 2nd, big mesosphere, the 3rd, little mesosphere, the 4th, bearing inner race, the 5th, ball, the 6th, ball retainer.
Single-row two course heart ball bearings and biserial two course heart ball bearing structures are similar, and single-row three course heart ball bearings and three layers of ball bearing structure of biserial are similar, the expression of therefore not drawing.
Advantage of the present utility model is as follows: can find out from two layers of centripetal ball bearing structure schematic diagram, can consist of relative rotation between bearing inner race and the mesosphere, and also can consist of relative rotation between bearing outer ring and the mesosphere, so just increased counterrotating possibility between the inside and outside circle of bearing. Compare with existing centripetal ball bearing, under same rotating speed, the motion of the ball of this bearing is slower, and therefore this bearing is not fragile. It can adapt to and runs up. Centripetal ball bearing as for three layers just can adapt to higher rotating speed.
Claims (1)
- A kind of multilayer centripetal ball bearing, it comprises bearing inner race, bearing outer ring, ball and ball retainer, it is characterized in that: between the inside and outside circle of bearing, one or two mesosphere is arranged, when a mesosphere is arranged, ball and ball retainer are housed between bearing inner race and the mesosphere and between mesosphere and the bearing outer ring; When two mesospheres were arranged, ground of cover of two mesospheres was arranged, between bearing inner race and the little mesosphere, between little mesosphere and the big mesosphere, between big mesosphere and the bearing outer ring ball and ball retainer is housed.
