Description
Technical field
The present invention relates to field of bearings, more particularly to a kind of sealed rolling bearing of resilient dust.
Background technology
Bearing is a kind of important parts in contemporary plant equipment, and its major function is the mechanical rotary body of support, drop
Coefficient of friction in low mechanical rotary body motion process, and ensure its rotating accuracy.
By the difference of motor element frictional property, bearing can be divided into rolling bearing and the major class of sliding bearing two, wherein rolling
Bearing is normalized, seriation, but its radial dimension, vibration and noise are larger compared with sliding bearing, and price is also higher.
Rolling bearing is typically made up of outer ring, inner ring, rolling element and the part of retainer four, complicated, the peace of retainer
Assembly and disassembly inconvenience, and poor sealing, easy oil leak is, it is necessary to improve.
The content of the invention
It is an object of the invention to provide a kind of sealed rolling bearing of resilient dust, lifting dust seal effect and guarantor
Hold frame dismounting convenience.
For up to this purpose, the present invention uses following technical scheme：
A kind of sealed rolling bearing of resilient dust, including：Bearing outer ring and bearing inner race, the bearing inner race are arranged concentrically on
In bearing outer ring, a circle steel ball is arranged at intervals between the bearing outer ring and bearing inner race, the steel ball both sides are set respectively
Have and be respectively arranged with retainer corresponding with steel ball, the cyclic spring on the inside of cyclic spring cover plate, the cyclic spring cover plate
Cover plate includes V-ring, the first spacing ring and the second spacing ring, and the V-ring is arranged concentrically on the first spacing ring and the second limit
Between the ring of position, first spacing ring is extended among bearing outer ring inwall, and second spacing ring extends to bearing inner race
Among outer wall, the arcuate surface of the retainer is in contact with V-ring inner concave.
Wherein, the retainer is respectively the steel-ball limiting ring for being provided with the continuous cambered surface groove of waveform, the steel ball
The cylindrical cambered surface groove with retainer fit.
Wherein, the V-ring, the first spacing ring and the integrated steel construction of the second spacing ring.
Wherein, it is provided with the first neck corresponding with the first spacing ring among the bearing outer ring inwall.
Wherein, it is provided with the second neck corresponding with the second spacing ring among the bearing inner race outer wall.
Wherein, it is provided with the inwall of the bearing outer ring outside the first slot rolling corresponding with steel ball, the bearing inner race
The second slot rolling corresponding with steel ball is provided with wall.
Beneficial effects of the present invention：A kind of sealed rolling bearing of resilient dust, retainer is spacing using V-ring progress,
And V-ring is under the support of the first spacing ring and the second spacing ring, with certain elasticity, the convenience of installation and removal is good,
First spacing ring and the second spacing ring are extended respectively in the inwall of bearing outer ring and the outer wall of bearing inner race, sealing effectiveness
Good, it is to avoid the problem of oil leak, use more stablizes.
