It connects, the second reinforcement annular end face Mi Quan annular is evenly equipped with several pressing plates, and one end of the pressing plate is fixed on bearing outer ring end
On face, other end is fixed on the end face of bearing inner race.
In a preferred embodiment of that invention, indent is provided with the outer of fixation clip to the bearing outer ring both sides of the face respectively
Groove, the bearing inner race both sides of the face are respectively arranged with inner groovy corresponding with external groove.
In a preferred embodiment of that invention, the retainer is respectively the rolling for being provided with the continuous cambered surface groove of waveform
Kinetoplast stop collar, the cambered surface groove in the outer circle and retainer of the rolling element fit.
In a preferred embodiment of that invention, the described first width for reinforcing ring type seal is greater than cyclic spring cover board
Width, the described second width for reinforcing ring type seal are greater than first annular reinforcement sealing ring.
In a preferred embodiment of that invention, the first rolling corresponding with rolling element is provided on the inner wall of the bearing outer ring
Slot is provided with the second slot rolling corresponding with rolling element on the outer wall of the bearing inner race.
Beneficial effects of the present invention: a kind of rolling bearing of adjustable leakproofness, it is close using width annular incremented by successively
Seal is repeatedly sealed, and the use of bearing is sealed the adjustment of circle often, strengthens the service life of bearing seal, is used
Effect is more stable.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
Specific embodiment
Below with reference to Fig. 1 and pass through specific embodiment to further illustrate the technical scheme of the present invention.
