Description
Technical field
The utility model relates to a kind of roller bearing, belongs to mechanical equipment technical field.
Background technique
In machinery, bearing is widely used, and the Environmental Conditions of some machinery is more severe, chip, dust are many, and these impurity likely drop in bearing, affect the normal operation of bearing, serious also can destroy bearing, finally causes whole device damage.
Summary of the invention
For solving the problem, the utility model provides a kind of structure simple, sealing bearing easy for installation.
The technological scheme that the utility model adopts for its problem of solution is:
A kind of roller bearing, comprise inner ring and outer ring, also comprise the sealing cover be connected between described inner ring and outer ring, the internal surface of described outer ring is provided with the first groove, the outer surface of described inner ring is provided with the second groove, the first end of described sealing cover is connected in described first groove, and its second end is consolidated with diaphragm seal, and the end abutment of described diaphragm seal is in described second groove.
Preferably, be provided with seal ring in described first groove, described first end is connected on the sidewall of described seal ring.
Preferably, described diaphragm seal comprises the mounting end be fixed on sealing cover and the sealed end contacted with the second groove, and described sealed end comprises the first surface be positioned at inside bearing, second that contacts with the second groove, and is positioned at the 3rd outside bearing.
Preferably, described sealing cover is arranged on after on bearing, and the 3rd forms with the bottom surface of the second groove the angle that is equal to or greater than 90 °.
The beneficial effects of the utility model are: by arranging sealing cover between the first groove and the second groove, can improve the sealing of bearing, arranging diaphragm seal in one end of sealing cover, when not reducing sealing, sealing cover can be facilitated to install.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail:
