Description
Technical field
The present invention relates to field of bearings, particularly a kind of shield bearing.
Background technology
Bearing (Bearing) is a kind of important spare part in contemporary mechanical equipment.Its major function is support machinery rotation
Swivel, reduces the friction coefficient in its motion process, and ensure its rotating accuracy.By the difference of motor element frictional property, axis
Two major class of rolling bearing and sliding bearing can be divided into by holding.Wherein rolling bearing is normalized, seriation, but with sliding bearing phase
More larger than its radial dimension, vibration and noise, price is also higher.Rolling bearing is generally by outer ring, inner ring, rolling element and holding
Four part of frame forms.By the shape of rolling element, rolling bearing is divided into two major class of ball bearing and roller bearing.Bearing due to making for a long time
With, often had in lubricating oil foreign matter entrance, when bearing runs at high speed, be easy to cause bearing damage.Dustproof cover is as axis
The parts held, are mainly used for preventing dust, impurity from entering Bearing inner, avoid influencing the performance of bearing.It is existing
Technology middle (center) bearing include set between bearing inner race, outer ring and the inside and outside circle of bearing rolling element, set in a ring it is dust-proof
Lid, dust-proof in the prior art to be stamped two kinds, the first is that dustproof cover is fixedly connected with bearing inner race, but dustproof cover outer ring and bearing
Outer ring contacts（In the form of either line contacts in the form of face contacts）, second is that dustproof cover inner ring fixes company with bearing inner race
Connect, dustproof cover outer ring is not contacted with bearing outer ring.For second of dustproof cover compares the first dustproof cover, advantage is that friction is compared
Small, shortcoming is that leakproofness is comparatively poor, and impurity is easily accessible in bearing；The advantages of the first dustproof cover be leakproofness compared with
Good, shortcoming is due to that the friction of dustproof cover outer ring and bearing outer ring is existed in the form of sliding friction, therefore dustproof cover and axis
Frictional resistance is bigger between bearing outer-ring, and this dustproof cover is not on this in lubricating status with regard to further with bearing outer ring
Frictional resistance between dustproof cover and bearing outer ring is increased, so as to reduce the performance of bearing.
The content of the invention
It is an object of the present invention to provide a kind of shield bearing.The present invention has the good dustproof effect, service life long and more
Change the characteristics of facilitating.
Technical scheme：A kind of shield bearing, including bearing outer ring, bearing outer ring connect through ball and bearing inner race
Connect, the both sides of ball are equipped with dustproof cover；Connection annular groove is additionally provided with the bearing outer ring；Also set on the bearing inner race
There is card slot；The dustproof cover includes resilient dust main body, and the outer rim of resilient dust main body, which is distributed with, clasps structure, clasps structure
Antifriction ball is inside connected with, the inner edge of resilient dust main body is equipped with oval fixed component；The antifriction ball and connection
Annular groove connects；The oval fixed component is connected with card slot；Described clasp is connected by oil duct between structure, and oil duct is equipped with
Oil storage cabin, oil storage cabin are connected with fuel feed hole.
In foregoing shield bearing, the antifriction ball is 0.01-0.03mm with clasping interstructural gap.
In foregoing shield bearing, readily removable ring is additionally provided with the resilient dust main body.
Compared with prior art, the present invention sets dustproof cover between bearing outer ring and bearing inner race, dustproof cover inner edge it is ellipse
Circle fixed component is fixed in the card slot of bearing inner race, and dustproof cover outer rim is equipped with and clasps structure, clasps structure and passes through antifriction ball
Connect the connection annular groove of edge bearing outer ring；By the structure, antifriction ball is rolling friction with being connected annular groove, and frictional force is small, into
And abrasion is reduced, effectively extend the service life of dustproof cover；The outer rim of dustproof cover is that its is dust-proof in embedded connection annular groove at the same time
Effect is more preferable, and moreover, the present invention also sets readily removable ring in resilient dust main body so that dismounting and change is convenient.The present invention
Connected between structure is clasped by oil duct, lubricating oil is efficiently entering and clasp inside configuration antifriction ball is lubricated,
Effectively reduce antifriction ball and clasp interstructural friction, and then prolong the service life.

Embodiment
The present invention is further illustrated with reference to the accompanying drawings and examples, but be not intended as to the present invention limit according to
According to.
The embodiment of the present invention：
Embodiment 1, a kind of shield bearing, are formed as shown in Figs. 1-3, including bearing outer ring 1, and bearing outer ring 1 is through ball 2 and bearing
Inner ring 3 connects, and the both sides of ball 2 are equipped with dustproof cover 4；Connection annular groove 5 is additionally provided with the bearing outer ring 1；The axis
Hold and card slot 6 is additionally provided with inner ring 3；The dustproof cover 4 includes resilient dust main body 7, and the outer rim of resilient dust main body 7 is distributed with
