The content of the invention
The purpose of this utility model：In order to overcome the defect of prior art, the utility model provides a kind of floating seal
Coil assembly, even if mandrel produces bending or elastic deformation, also can guarantee that the sealing between sealing ring and mandrel；Furthermore, it is possible to
Prevent extraneous foreign matter from directly impacting sealing ring, so as to be avoided that sealing ring is damaged.
The technical solution of the utility model：A kind of floating seal coil assembly, it is characterised in that：Include guard ring, sealing ring
And for supporting the ring skeleton of sealing ring, the end face of described guard ring side is provided with annular groove, annular groove extension
To the inner ring surface of guard ring, described skeleton, sealing ring are placed in annular groove, and the inner ring surface of sealing ring is provided with sealing lip,
Between the outer ring surface of sealing ring and the side wall of annular groove floating space is radially provided with along guard ring.
Using above-mentioned technical proposal, when floating seal coil assembly is installed between bearing outer ring and mandrel, it is only necessary to will
End face of the guard ring provided with annular groove side is towards inner side, and the end face of opposite side is towards outside, the sealing lip on sealing ring
It is interference fitted with mandrel, when mandrel produces bending or elastic deformation, sealing ring can radially automatic adjusting position, it is ensured that sealing
All the time sealing state is between lip and mandrel；Moreover, guard ring can effectively prevent extraneous foreign matter from directly impacting sealing ring, can
To avoid sealing ring from damaging.
Further setting of the present utility model：Described sealing ring is fitted in skeleton towards the end of annular groove bottom side
On face, the described outer ring surface of sealing ring aligns setting with the outer ring surface of skeleton.
Using above-mentioned further setting, it can so cause the good airproof performance between skeleton and annular groove bottom, prevent
Dust enters in bearing between skeleton and annular groove bottom, further improves its sealing property.
It is of the present utility model further to set：The inner ring surface patch of support ring, support ring and skeleton is additionally provided with sealing ring
Close.
Further set using above-mentioned, support ring can both cause in mandrel normal work, sealing ring connects with skeleton
Connect and more stablize, can ensure that sealing ring can be synchronized with the movement at its position of adjust automatically with skeleton again.
It is of the present utility model further to set again：Axial direction of the described sealing lip along guard ring is one in front and one in back provided with two.
Further set again using above-mentioned, further improve the sealing property between mandrel and sealing ring, it is possible to achieve
Dual sealing functions.
It is of the present utility model further to set again：Annular groove position is corresponded on the lateral wall of described guard ring along its week
To provided with annular boss.
Further set again using above-mentioned, it is only necessary to which correspondence annular boss position sets annular positioning groove on outer ring,
During installation, annular boss is embedded in the positioning that guard ring and outer ring can be achieved in annular positioning groove, it is easier for installation；Other ring
Shape boss is correspondingly arranged at annular groove position, can so improve the intensity of guard ring.
It is of the present utility model further to set again：The described skeleton end face opposite with annular groove bottom is provided with ring
Shape oil storage tank.
Further set again using above-mentioned, oil storage tank can store lubricating oil so that wear and tear small between skeleton and outer ring,
Extend its service life.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model specific embodiment；
Fig. 2 is the utility model specific embodiment and bearing outer ring, mandrel mounting structure schematic diagram.
Embodiment
As shown in Figure 1, 2, a kind of floating seal coil assembly, includes guard ring 1, sealing ring 2 and for supporting sealing ring 2
Ring skeleton 3, the end face of the described side of guard ring 1 is provided with annular groove 11, and annular groove 11 extends to the inner ring of guard ring 1
On face, described skeleton 3, sealing ring 2 are placed in annular groove 11, and the inner ring surface of sealing ring 2 is provided with sealing lip 21, sealing ring
Between 2 outer ring surface and the side wall of annular groove 11 floating space 4 is radially provided with along guard ring 1.By the component of floating seal ring 2 peace
When being attached between bearing outer ring 1 ' and mandrel 2 ', it is only necessary to by end face of the guard ring 1 provided with the side of annular groove 11 towards inner side, separately
The end face of side is towards outside, and the sealing lip on sealing ring 2 is interference fitted with mandrel, when mandrel produces bending or elasticity becomes
Shape, sealing ring 2 can radially automatic adjusting position, it is ensured that be in sealing state between sealing lip and mandrel all the time；Moreover, shield
