Description
Technical field
The utility model is related to a kind of bearings, more particularly, to a kind of biserial closed type taper roller roller bearing.
Background technology
It usually needs to use idler wheel, the split type structure of existing idler wheel generally use, in wheel rim in technical field of steel rolling
It is embedded in double-row conical bearing, in order to improve the applying working condition and lubricant effect of double-row conical bearing, extending it makes
It with the service life, needs in addition to design sealing structure, and the axis of outer ring spacer or cone spacer adjustment double-row conical bearing need to be utilized
It is complicated to clearance, assembly trouble.
Utility model content
The applicant is directed to above-mentioned problem, has carried out Improvement, provides a kind of biserial closed type taper roller idler wheel
Bearing, simple and compact for structure, manufacturing cost is low, easy to assembly quick using monolithic construction, improves raceway location contacts shape
Condition prolongs the service life.
In order to solve the above-mentioned technical problem, the utility model adopts the following technical scheme：
A kind of biserial closed type taper roller roller bearing, including outer ring, 2 inner rings, 2 row tapered rollers and 2 holdings
Frame is provided with 2 oil sealings for sealing up gap between the inner ring and the outer ring between the inner ring and the outer ring,
2 oil sealings are arranged in the outside of the 2 row taper rollers, and 2 inner rings are oppositely arranged, the inside of 2 inner rings
End is respectively symmetrically equipped at least three semi-circular recesses；The oil sealing is connected by the L-shaped skeleton in section and section in the lip of J-shaped
Composition is connect, the skeleton interference fit is fixedly connected with the endoporus of the outer ring, and the outer circumference surface of the lip and the inner ring connects
It touches；The cross sectional shape of the external peripheral surface of the outer ring is arc-shaped.
Further：
The inner end of 2 inner rings is respectively symmetrically equipped with 4 semi-circular recesses.
The utility model has technical effect that：
A kind of biserial closed type taper roller roller bearing disclosed by the utility model, simple and compact for structure, manufacturing cost
It is low, using monolithic construction, idler wheel, double-row conical bearing and sealing structure are integrated, can be used directly as idler wheel, assembled
It is convenient and efficient, improve raceway position contact condition, prolongs the service life.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the cutaway view Amplified image of oil sealing.
Specific implementation mode
Specific embodiment of the present utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in Figure 1, 2, the utility model includes the inner ring 2 of outer ring 1,2,2 row tapered rollers 3 and 2 retainers 4, interior
2 oil sealings, 5,2 oil sealings 5 for sealing up gap between inner ring 2 and outer ring 1 are provided between circle 2 and outer ring 1 to be arranged 2
The outside of row tapered roller 3.2 inner rings 2 are oppositely arranged, and the inner end of 2 inner rings 2 is respectively symmetrically equipped at least three semicircle
Groove 6, in the present embodiment, the inner end of 2 inner rings 2 are respectively symmetrically equipped with 4 semi-circular recesses 6, can be to axis by groove 6
Hold interior filling lubricating oil.Oil sealing 5 is connected and composed with section in the lip 52 of J-shaped by the L-shaped skeleton 51 in section, and skeleton 51 is by steel
Plate is made, and for lip 52 by adding fluorubber to be made, skeleton 51 is interference fitted the endoporus for being fixedly connected with outer ring 1, lip 52 and inner ring 2
Outer circumference surface contacts.The cross sectional shape of the external peripheral surface of outer ring 1 is arc-shaped.
The utility model is designed to overall structure, integrates idler wheel, double-row conical bearing and sealing structure, and outer ring 1 collects
At idler wheel wheel rim and bearing outer ring function, there is relatively thick, load, the section of the external peripheral surface of outer ring 1 can be absorbed impact
Shape is arc-shaped, can be used directly as wheel, quick and easy for installation.Inner ring 2 is designed to two, but centre is not added with spacer ring,
Part processing precision is improved, directly apolegamy is combined into required axially and radially clearance when assembly, improves raceway location contacts
Situation prolongs the service life.The oil sealing 5 of both sides plays the role of sealing, keeps out foreign intrusion, and can effectively prevent lubricating
Fat is lost in, and improves sealing performance and high temperature resistance.By the oil groove pair on the groove 6 of the inner end of 2 inner rings 2 and axis when assembly
Standard can ensure the good lubrication state of bearing, prolong the service life by axis and groove 6 to bearing supplemental lubrication fat.
