Abstract
The utility model is related to a kind of pair of point contact type bearing of inner ring 8；Including inner ring, outer ring and rolling element, described rolling element is built between inner ring and outer ring, it is characterised in that：Described outer ring is the interior raceway of two row side by side, and described inner ring is two, corresponding to be installed under double raceways of outer ring；Gap is left between two described inner rings.The purpose of this utility model is：A kind of pair of point contact type bearing of inner ring 8 is provided, heavy duty is solved and requires smooth bearing again simultaneously.
Description
Technical field
The utility model is related to a kind of bearing, is related specifically to a kind of bearing of a pair of inner ring.
Background technology
Bearing is a kind of important spare part in contemporary plant equipment.Its major function is the mechanical rotary body of support, reduction
Coefficient of friction in its motion process, and ensure its rotating accuracy.Rolling bearing is general by outer ring, inner ring, rolling element and holding
The part of frame four is constituted, and is strictly speaking made up of outer ring, inner ring, rolling element, retainer, sealing, the big part of lubricating oil six.Simply
For, just it may be defined as rolling bearing as long as possessing outer ring, inner ring, rolling element.Conventionally, the axis of rolling is forwarded
It is dynamic whether smooth and strong, depending on rolling element and outer ring, inner ring contact point number, when contact point is more；Its bearing capacity
Necessarily increase；But the speed rotated can then decline, therefore, in the market is badly in need of a kind of axle for integrating and loading with quick-action smoothly
Hold.
The content of the invention
Goal of the invention of the present utility model is：A kind of pair of point contact type bearing of inner ring 8 is provided, heavy duty is solved simultaneously again
Seek smooth bearing.
To complete foregoing invention purpose, what the utility model was realized in：A kind of pair of point contact type bearing of inner ring 8, bag
Inner ring, outer ring and rolling element are included, described rolling element is built between inner ring and outer ring, it is characterised in that：Described outer ring is
The interior raceway of two row side by side, described inner ring is two, corresponding to be installed under double raceways of outer ring；Two described inner rings it
Between leave gap.
Above-mentioned technical proposal is improved further and limited, described the cylindrical of two inner rings is provided with and outer ring raceway
Corresponding outer raceway.
Above-mentioned technical proposal is improved further, the outer raceway clamping relative with the interior raceway of outer ring of described inner ring
Rolling element, at least four point positions of each rolling element and outer raceway and interior raceway contact.
Above-mentioned technical proposal is improved further, bearing contact angle α≤60 °.
Above-mentioned technical proposal is improved further, dust cap is provided between the inner ring and outer ring.
Above-mentioned technical proposal is improved further, sealing ring, sealing ring peripheral hardware are provided between the inner ring and outer ring
Dust cap.
It is of the present utility model to have the technical effect that：Bearing is using double inner ring Double-row ball structures, independent row steel ball and bearing
Inner ring and outer ring tool have 4 contact points, and double inner rings have 8 contact points with outer ring.Because double inner rings are designed, between two inner rings
Away from there is certain free degree, realize that 8 contact points of bearing can stress.Realization had not only increased load but also while had taken into account speed.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As illustrated, a kind of pair of point contact type bearing of inner ring 8, including inner ring 1, outer ring 2 and rolling element 6, described rolling
Body 6 is built between inner ring 1 and outer ring 2, and described outer ring is the interior raceway of two row side by side, and described inner ring is two, correspondence
Be installed under double raceways of outer ring；Gap is left between two described inner rings;Two described inner rings it is cylindrical be provided with
The corresponding outer raceway of outer ring raceway.The outer raceway of described inner ring is relative with the interior raceway of outer ring to hold rolling element, and this is each
At least four point positions of rolling element and outer raceway and interior raceway contact；Bearing contact angle α≤60 °.Between the inner ring and outer ring
Provided with dust cap.Sealing ring, the peripheral hardware dust cap 3 of sealing ring 4 are provided between the inner ring and outer ring.
It is of the present utility model to have the technical effect that：Bearing is using double inner ring Double-row ball structures, independent row steel ball and bearing
Inner ring and outer ring tool have 4 contact points, and double inner rings have 8 contact points with outer ring.Because double inner rings are designed, between two inner rings
Away from there is certain free degree, realize that 8 contact points of bearing can stress.Realization had not only increased load but also while had taken into account speed.
Claims (5)
