Description
Technical field
The utility model is related to field of bearings, particularly a kind 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（With in the form of face contacts or in the form of linear contact lay）, second is that dust cap inner ring fixes company with bearing inner race
Connect, dust cap outer ring does not contact with bearing outer ring.Second dust cap compared to for the first dust cap, advantage be friction ratio compared with
It is small, have the disadvantage that sealing is comparatively poor, impurity is easily accessible in bearing；The advantage of the first dust cap be sealing compared with
It is good, have the disadvantage because the friction of dust cap outer ring and bearing outer ring is present in the form of sliding friction, therefore dust cap and axle
Frictional resistance is than larger between bearing outer-ring, and this dust cap and bearing outer ring are not in lubricating status this just further
Frictional resistance between dust cap and bearing outer ring is increased, so as to reduce the performance of bearing.
The content of the invention
The purpose of this utility model is, there is provided a kind of shield bearing.The utility model has good dustproof effect, uses the longevity
Life is long and changes the characteristics of facilitating.
The technical solution of the utility model：A kind of shield bearing, including bearing outer ring, bearing outer ring is through in ball and bearing
Circle connection, the both sides of ball are equipped with dust cap；Connection annular groove is additionally provided with described bearing outer ring；On described bearing inner race
It is additionally provided with draw-in groove；Described dust cap includes resilient dust main body, and the outer rim of resilient dust main body is distributed with clasps structure, clasps
Antifriction ball is connected with structure, the inner edge of resilient dust main body is provided with oval fixed component；Described antifriction ball with
Connection annular groove connection；Described oval fixed component is connected with draw-in groove；It is described clasp structure between connected by oil duct, on oil duct
Oil storage cabin is provided with, oil storage cabin is connected with fuel feed hole.
In foregoing shield bearing, described antifriction ball is 0.01-0.03mm with interstructural gap is clasped.
In foregoing shield bearing, readily removable ring is additionally provided with described described resilient dust main body.
Compared with prior art, the utility model sets dust cap, dust cap inner edge between bearing outer ring and bearing inner race
Oval fixed component be fixed in the draw-in groove of bearing inner race, dust cap outer rim is provided with clasps structure, clasps structure by antifriction
Ball connects the connection annular groove of edge bearing outer ring；By the structure, antifriction ball is rolling friction, frictional force with annular groove is connected
It is small, and then abrasion is reduced, effectively extend the service life of dust cap；The outer rim of dust cap is that insertion is connected in annular groove simultaneously,
More preferably, moreover, the utility model also sets readily removable ring to its dust-proof effect in resilient dust main body so that dismounting and change side
Just.The utility model is connected between clasp structure by oil duct, lubricating oil is efficiently entering and is clasped inside configuration to antifriction
Ball is lubricated, and effectively reduces antifriction ball and clasps interstructural friction, and then increases the service life.
