Description
Technical field
The present invention relates to a kind of rolling bearing, and it has race ring, a large amount of rolling elements and is fixed on close on race ring
Sealing, the rolling element roll on the raceway of race ring around the rotation axis of rolling bearing.
Background technology
The well known in the art this rolling bearing of varied form, wherein seal will prevent dirt from penetrating into
Rolling bearing and/or lubricant medium overflow from rolling bearing.
Such as a kind of self-aligning roller bearing there is known by DE60306638T2, it includes outer ring, and the outer ring, which has, to be used
In arranging the raceway of (Lagerreihen) around the rolling element of rotation axis with duplex bearing, and also include two seals, this is close
Sealing is fixed on the axial end portion of outer ring on the outer ring.These seals include angular and annular plate, their bases
On the convex shoulder for the outer cover that a DE60306638T2 form of implementation is pressed in outer ring.DE60306638T2 solution
The shortcomings that be：Thus weaken and power be transferred to outer cover needed for housing, the installation in trouble of seal, seal it is accurate
Orient and therefore sealing effectiveness can only be adjusted struggle with itself, and seal can slide in rolling bearing work.
The content of the invention
The task that the present invention is based on is to disclose such rolling bearing, and the rolling bearing avoids recited above
The shortcomings that prior art, the especially rolling bearing, provide the seal with higher confining force, and wherein seal can letter
Install singly and inexpensively.
Inventor have realised that arriving, it is determined that under applicable cases, seal is bonded on race ring and ensure that to seal
It is fully fixed, high confining force of the seal on race ring is especially can be achieved on, and be therefore very simple including less structure
The cheap solution of part and therefore cost.
Here, seal can be to be either bonded on inner ring or be bonded on outer ring, the seal is preferably adhered to
On fixed race ring.For example, one-component jointing material or two-component jointing material are arranged to jointing material.
The rolling bearing can be annular bearing with rolling contact or axial antifriction bearing.The present invention can be for example used in footpath
Into self-aligning roller bearing, taper roll bearing, cylinder roller bearing or ball bearing.It is if rolling bearing is complete
Sealing, then preferably equally seal is bonded in the second end face of race ring according to the present invention.
In the case of annular bearing with rolling contact, the seal is preferably adhered on end face, and in axial antifriction bearing situation
Under, the seal is preferably adhered on cover.
In addition, be bonded in by seal on axial end (face outwards wound on the bearing midpoint of axial direction), can
Conventional radial rolling bearing is used to realize, especially standardizes the rolling bearing of (such as DIN).So, consolidating with regard to seal
It is not required for for fixed in rolling element space (region between the race ring of rolling bearing, rolling element roll in this region)
There is position.It can also avoid being fixed on annular bearing with rolling contact from engagement (Hintergreifen) race ring below, such as seal
Cover on.
It is arranged to according to a preferred implementing form, the seal has metallic reinforcement and is made up of synthetic rubber
Seal disc, and the reinforcing body is bonded on the axial end of the race ring.Metallic reinforcement is preferably directly bonded on axle
Hold circle above or be directly bonded on the end face of race ring, and for improving the stability or shape and positional precision of seal.
Seal disc typically has one or more sealing lips, and the sealing lip is in another example laterally contact the from the raceway of second bearing circle
Two race rings.Seal disc only diametrically can be connected on reinforcing body, or according to preferred embodiment by reinforcing body radially
Extension, preferably completely radially extend along it and covered at least one side.The seal disc, which can especially vulcanize to described, to be added
On solid.
But in principle it is also contemplated that being arranged to, seal has the seal disc being made up of synthetic rubber, and seals
Disk is bonded on the axial end of race ring, is especially characterised by, the seal does not have metallic reinforcement.This is special
Simple and therefore cheap structure.
Present invention has the advantage that seal is easily secured on the rolling bearing (afterwards) of standardization.For
The axial dimension of this rolling bearing is not changed especially, race ring can have convex shoulder, an axial direction of convex shoulder on its end face
Depth is prolonged more than or equal to axial direction of the seal in the region that the seal of the seal is bonded on race ring thereon
Stretch so that seal stretches out no more than race ring in the axial direction.The seal terminates with flushing with race ring, or relatively
It is inside in the axial direction in race ring, i.e. to be retracted towards axial antifriction bearing center.Except making under predetermined installation situation
Outside this rolling bearing, this fixation of seal it also avoid the damage sealing when transporting or installing rolling bearing
Part.
Although according to the present invention rolling bearing with the conventional rolling bearing with seal compared with much it is excellent
Point.But have shown, because adhesive surface is big, accurate due to be carried out to jointing material especially in the case of big bearing
Metering and jointing material are evenly distributed when improperly manufacturing, and the bonding of seal can cause seal relative to rotary shaft
Line decentraction and/or can cause bonding connect in blow-by.Therefore, according to a particularly advantageous form of implementation, in order to
Bonding connection is improved, is especially arranged to also for confining force and sealing effectiveness is improved, the race ring has on its end face
At least one recess, wherein at least one recess is at least partly covered by the seal.The recess can be with
Realize and accommodate jointing material.So, during seal is installed, targetedly only jointing material is introduced into recess.
If end face has convex shoulder, at least one recess can be introduced into the convex shoulder of end face.
The recess can have diversified shape.Such as it may also be considered that, at least one recess
The groove that axis is revolved around it by one or more is formed.By way of groove unbroken loop is around rotation axis, it is possible to achieve
Highly uniform material fit connection between seal and race ring, and maximum sealing effectiveness can also be obtained.Groove can be with
Moved towards with one heart relative to rotation axis, but the helical groove with multiple circles can also be set.
According to a form of implementation, at least one recess is covered by seal along radially extending for groove completely.Cause
And the jointing material in recess completely attaches to seal/race ring, so as to realize that maximum jointing material utilizes, and hinder
Only jointing material overflows.
Have shown, too deep recess is inappropriate, because jointing material needs long time hardening, and mistake
Flat recess is merely able to realize insufficient confining force.Recess depth in 0.1mm between 0.7mm when, can obtain
Obtain optimum efficiency.
According to a form of implementation, rolling bearing has second bearing circle, and the seal seals the race ring
With the rolling element space between the second bearing circle.Herein preferably, two seals can be bonded in the axle of rolling bearing
To on end.
