Embodiment
Below with reference to Fig. 1~Fig. 4, the invention will be further described.
According to a kind of rolling bearing 100 of the present invention, rolling bearing 100 includes rolling bearing body 10, rolling bearing sheet
Body 10 includes bearing outer ring, bearing inner race and rolling element, and rolling element is installed between bearing outer ring and bearing inner race, in addition to end
Lid 1, end cap 1 are fixedly connected with bearing inner race, including：Collar 12, ceiling plate portion 11 and bearing grease.
Collar 12, collar 12 are cylindrical tube shape structure, are connected with bearing inner race, that is to say, that collar 12 and axle
The inner ring held is engaged, so as to replace the connection between bearing inner race and connecting shaft, so it is possible to prevente effectively to bearing inner race
Damage.
Ceiling plate portion 11, cover plate are stretched out by the periphery wall of collar 12, are engaged with bearing outer ring, specifically, cover plate
Portion 11 is located at one end of collar 12, extends to bearing outer ring by the periphery wall of collar 12, and do not connect with bearing outer ring portion
Touch, effectively rolling bearing body 10 can so be covered, prevent the impurity in external environment condition from entering rolling bearing body 10
In and damage the service life of rolling bearing body 10；And oil groove 111 is provided with ceiling plate portion 11, bearing grease is located at oil groove
In 111, by setting bearing grease in oil groove 111, can so it play a part of lubrication to rolling bearing body 10, so as to
Extend the service life of rolling bearing body 10.
By the way that end cap 1 is fixedly connected on the inner ring of rolling bearing body 10, impurity can be avoided to enter rolling bearing
Rolling bearing body 10 is caused to damage in body 10, oil groove 111 is provided with end cap 1, so can effectively must be to rolling
Bearing body 10 is lubricated, and prevents that rolling bearing body 10 is insufficient because lubricating in the course of the work, and causes abrasion to aggravate,
So as to effectively extend the service life of rolling bearing body 10.
In one embodiment of the invention, oil groove 111 is cyclic structure, and is oppositely arranged with rolling element, so can be with
Make rolling element worked along with rolling bearing body 10 and carry out rotation and revolution during, can more fully with axle
Hold grease to be in contact, so as to improve the lubricant effect of rolling bearing body 10, and then extend the use longevity of rolling bearing body 10
Life.
In one embodiment of the invention, collar 12 is integrally formed with ceiling plate portion 11.That is, end cap 1 is in life
In production and manufacturing process, it can be integrally formed by way of casting or forging, the overall construction intensity of such end cap 1 is high, and
And the trouble of assembling can be avoided.
Further, collar 12 and the junction of ceiling plate portion 11 are provided with rounding 121, can so be effectively prevented from axle
Neck 12 and the junction of ceiling plate portion 11 produce stress concentration phenomenon, so as to avoid producing fatigue crack in junction, strengthen axle
Neck 12 and the bonding strength of ceiling plate portion 11.
Further, end cap 1 is symmetrical arranged, and so effectively can be wrapped the both sides of rolling bearing body 10,
Strengthen the sealing to rolling bearing body 10, prevent impurity enters in rolling bearing body 10 from causing to damage to it.
In some embodiments of the invention, the length of collar 12 is at most the half of bearing inner race width, is so existed
When end cap 1 is symmetrical arranged, the installation of end cap 1 can be easy to.
Preferably, it is fastenedly connected between end cap 1 and rolling bearing body 10 by screw 2, end cap 1 is provided with multiple the
A positioning hole 112, bearing inner race are provided with multiple second positioning holes 101, multiple first positioning holes 112 and multiple second positioning holes
101 correspond, and screw 2 sequentially passes through the first positioning hole 112 and the second positioning hole 101.So it is easy to end cap 1 and rolling bearing
Installation and dismounting between body 10, also allow for the maintenance and maintenance in later stage.
