Description

A kind of rolling bearing of adjustable sealing
Technical field
The present invention relates to field of bearings, more particularly to a kind of rolling bearing of adjustable sealing.
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 a series in bearing products.And bearing is in use, sealing is particularly important.Typically Rolling bearing after a long time use, its sealing wear, it is poor to easily cause sealing, so as to cause rolling bearing roll inside Body dust enters, and in the course of time, causes ball to damage, causes the damage of bearing, it is impossible to normal work, shortens the entirety of bearing Service life.
The content of the invention
It is an object of the invention to provide a kind of rolling bearing of adjustable sealing, the use longevity of bearing seal is strengthened Life, using effect is more stablized.
For up to this purpose, the present invention uses following technical scheme：
A kind of rolling bearing of adjustable sealing, including：Bearing outer ring and bearing inner race, the bearing inner race are arranged on bearing In outer ring, a circle rolling element is arranged at intervals between the bearing outer ring and bearing inner race, the rolling element both sides are set respectively Have and be respectively arranged with retainer corresponding with rolling element, the annular elastomeric on the inside of cyclic spring cover plate, the cyclic spring cover plate Property cover plate on the outside of be respectively arranged with the first reinforcement O-ring seal, the is provided with the outside of the first reinforcement O-ring seal Two strengthen O-ring seal, and the first reinforcement O-ring seal is fixedly connected by screw in compression with cyclic spring cover plate, institute State the close circle end face annular of the second reinforcement annular and be evenly equipped with several pressing plates, one end of the pressing plate is fixed on bearing outer ring end face, Other end is fixed on the end face of bearing inner race.
In a preferred embodiments of the invention, indent is provided with the outer of fixation clip to bearing outer ring both sides end face respectively Groove, bearing inner race both sides end face is respectively arranged with the inner groovy corresponding with external groove.
In a preferred embodiments of the invention, the retainer is respectively the rolling for being provided with the continuous cambered surface groove of waveform Kinetoplast spacing ring, the cylindrical cambered surface groove with retainer of the rolling element fits.
In a preferred embodiments of the invention, the described first width for strengthening O-ring seal is more than cyclic spring cover plate Width, the described second width for strengthening O-ring seal is more than first annular reinforcement sealing ring.
In a preferred embodiments of the invention, the first rolling corresponding with rolling element is provided with the inwall of the bearing outer ring The second slot rolling corresponding with rolling element is provided with groove, the outer wall of the bearing inner race.
Beneficial effects of the present invention：A kind of rolling bearing of adjustable sealing, using incremented by successively annular close of width Seal is repeatedly sealed, and the use of bearing carries out the adjustment of sealing ring often, strengthens the service life of bearing seal, uses Effect is more stablized.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Embodiment
Technical scheme is further illustrated with reference to Fig. 1 and by specific embodiment.
A kind of rolling bearing of adjustable sealing, including：Bearing outer ring 8 and bearing inner race 2, the bearing inner race 2 are set Put in bearing outer ring 8, a circle rolling element 1, the rolling element 1 are arranged at intervals between the bearing outer ring 8 and bearing inner race 2 Both sides are respectively arranged with cyclic spring cover plate 4, and the inner side of cyclic spring cover plate 4 is respectively arranged with keep corresponding with rolling element Frame 5, the outside of the cyclic spring cover plate 4 is respectively arranged with the first reinforcement O-ring seal 6, and described first strengthens ring packing The outside of circle 6 is provided with the second reinforcement O-ring seal 7, and described first, which strengthens O-ring seal 6, passes through screw in compression and annular Elastic cover plate 4 is fixedly connected, and described second, which strengthens annular 7 end face annulars of close circle, is evenly equipped with several pressing plates 9, the one of the pressing plate 9 End is fixed on the end face of bearing outer ring 8, and other end is fixed on the end face of bearing inner race 2, is strengthened second the close circle 7 of annular and is entered Row is compressed, and strengthening the close circle 7 of annular by second by bolt is pressed on the outside of the first reinforcement O-ring seal 6, forms multi-level close Envelope, adjusts the elastic of sealing ring, so as to change sealing according to the pretightning force of bolt.
Further, indent is provided with the external groove 81 of fixation clip, the bearing to the both sides end face of bearing outer ring 8 respectively The both sides end face of inner ring 2 is respectively arranged with the inner groovy 21 corresponding with external groove 81, the placement for pressing plate 9.
Further, the retainer 5 is respectively the spacing ring of rolling element 1 for being provided with the continuous cambered surface groove of waveform, institute The cambered surface groove stated on the cylindrical and retainer 5 of rolling element 1 fits, and is conducive to the rolling of rolling element 1,5 pairs of rollings of retainer While body 1 carries out spacing, frictional force is reduced.
Further, the described first width for strengthening O-ring seal 6 is more than the width of cyclic spring cover plate 4, described second The width for strengthening O-ring seal 7 is more than first annular reinforcement sealing ring 6, increases sealing successively.
Further, it is provided with the inwall of the bearing outer ring 8 in the first slot rolling 82 corresponding with rolling element, the bearing The second slot rolling 22 corresponding with rolling element is provided with the outer wall of circle 2, good limit effect is conducive to rolling and the profit of rolling element 1 It is sliding.
