Description
Technical field
The utility model is related to field of bearings, particularly a kind of dust cap of shield bearing.
Background technology
Bearing (Bearing) is a kind of important spare part in contemporary plant equipment.Its major function is support machinery rotation
Swivel, reduces the coefficient of friction in its motion process, and ensure its rotating accuracy.By the difference of motor element frictional property, axle
Holding can be divided into rolling bearing and the major class of sliding bearing two.Wherein rolling bearing is normalized, seriation, but with sliding bearing phase
Radial dimension, vibration and noise than it is larger, and price is also higher.Rolling bearing is general by outer ring, inner ring, rolling element and holding
The part of frame four constitutes.By the shape of rolling element, rolling bearing is divided into ball bearing and the major class of roller bearing two.Bearing due to making for a long time
With, foreign matter entrance is often had in lubricating oil, when bearing runs at high speed, easily cause bearing damage.Dust cap is used as axle
The parts for holding, are mainly used in preventing dust, impurity from entering Bearing inner, it is to avoid the performance of influence bearing.It is existing
Technology middle (center) bearing include between bearing inner race, outer ring and the inside and outside circle of bearing set 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 dust cap is fixedly connected with bearing inner race, but dust cap outer ring and bearing
Outer ring contacts, and second is that dust cap inner ring is fixedly connected with bearing inner race, dust cap outer ring does not contact with bearing outer ring.Second
Dust cap is planted compared to for the first dust cap, advantage is that friction is smaller, has the disadvantage that sealing is comparatively poor, impurity
It is easily accessible in bearing；The advantage of the first dust cap is preferable sealing, is had the disadvantage due to dust cap outer ring and bearing outer ring
Friction be in the form of sliding friction exist, therefore between dust cap and bearing outer ring frictional resistance than larger and this
This just further increases the resistance that rubbed between dust cap and bearing outer ring during dust cap and bearing outer ring are not on lubricating status
Power, so as to reduce the performance of bearing.For this applicant devises a kind of shield bearing, its good dustproof effect, the longevity is used
Life length.But the shield bearing also needs that a kind of dust cap is matching to be used, do not find also matching well to make at present
Dust cap.
The content of the invention
The purpose of this utility model is, there is provided a kind of dust cap of shield bearing.The utility model has dust-proof effect
Fruit is good and changes the characteristics of facilitating.
The technical solution of the utility model：A kind of dust cap of shield bearing, including resilient dust main body, resilient dust
The outer rim of main body is distributed with clasps structure, clasps and antifriction ball is connected with structure, and the inner edge of resilient dust main body is provided with
Oval fixed component；Described antifriction ball is connected with annular groove is connected；Described oval fixed component is connected with draw-in groove；Described
Connected by oil duct between clasping structure, oil duct is provided with oil storage cabin, and oil storage cabin is connected with fuel feed hole.
In the dust cap of foregoing shield bearing, described antifriction ball is 0.01- with interstructural gap is clasped
0.03mm。
In the dust cap of foregoing shield bearing, readily removable ring is additionally provided with described described resilient dust main body.
Compared with prior art, the utility model sets in resilient dust main body outer rim and clasps structure, clasps living in structure
It is dynamic to be connected with antifriction ball, in resilient dust main body inner edge, oval fixed component is set；When using, oval fixed component is loaded
Make dust cap more firm in the draw-in groove of bearing inner race, the connection annular groove of antifriction ball and bearing outer ring is connected；Due to dust cap
Outer rim be that its dust-proof effect is more preferable in embedded connection annular groove.Structure of clasping of the present utility model connects edge by antifriction ball
The connection annular groove of bearing outer ring；By the structure, antifriction ball is rolling friction with annular groove is connected, and frictional force is small, and then is reduced
Abrasion, effectively extends the service life of dust cap.To sum up, the utility model can be well matched with using with shield bearing.This
Utility model also sets readily removable ring in resilient dust main body so that dismounting and change is convenient.The utility model is between clasp structure
Connected by oil duct, lubricating oil is efficiently entering and clasp inside configuration antifriction ball is lubricated, effectively reduced and subtract
Rub ball with clasp interstructural friction, and then increase the service life.
