Technical field
The utility model relates to the field of ball bearing, particularly relates to a kind of ball bearing with sealing gasket.
Background technique
Affect factor mainly two aspects in bearing operational reliability and life-span, one is the sealed precision of bearing part, if bearing part sealed precision is inadequate, its reliability is just poor, and the oiling agent in bearing can to outward leakage, or make bearing other places material invade Bearing inner in running, sealing effect is lost, oiling agent is run off, bearing wear, thus reduce operational reliability and the service life of bearing.Two is geometric accuracy and mechanical propertys of bearing ring and rolling element working surface, if there is larger defect in the shape of work and mechanical property, ratio is if any local defect in geometrical deviation, course of working, capital increases the basic stress of Bearing inner when running up, thus reduces bearing capacity.
And for the ball bearing used in frequent starting in direct drinking fountain, its working environment is moist, therefore the sealability for bearing part proposes higher requirement, in prior art, bearing is installed water proof parts outward, in order to install closely with water proof part fits, edge requirement on machining accuracy for bearing is very high, therefore need to be made into long beveled edge to simplify the edge, outer ring processing usual bearing, but extra like this adds manufacturing procedure, and also very unfavorable for the compact structure layout of integrated straight drinking machine.
Model utility content
In order to overcome shortcoming of the prior art, the purpose of this utility model is to provide a kind of ball bearing with outer ring, circular arc chamfering edge with sealing gasket.
The utility model provides a kind of ball bearing, comprise: inner ring and outer ring, described inner ring and outer ring realize the relative rotation perpendicular to inner ring and place, outer ring plane respect to one another by the multiple balls be filled in wherein, and inner ring has common axis with the described relative rotation of outer ring; Described inner ring has the raceway being positioned at described inner ring outer surface, and described outer ring has the outer raceway being positioned at described inner surface; Described ball is filled with between described interior raceway and described outer roller surface;
Inner ring is provided with inner ring chamfering away from the inside edge of interior raceway, outer ring is provided with outer ring chamfering away from the outer ledge of outer raceway.
Have sealing gasket in the side of ball bearing, inner ring side has the first seal groove, on inner ring, the wall height of the first seal groove both sides is not etc., and the height difference wherein between the lower side of inner ring sidewall and inner ring chamfering is L, and L equals the thickness of sealing gasket body; Height difference on outer ring in the second seal groove between the lower side of sidewall and inner ring chamfering is L1, and L1 is greater than L;
Sealing gasket is ring, is arranged between the first seal groove and the second seal groove;
The body of sealing gasket has a kink, is arranged on the inner ring place of annular seal pad, and wherein kink is arranged among the first seal groove, and the labyrinth sealing end of sealing gasket is arranged among the second seal groove;
Described labyrinth sealing end is arranged by the parts space of multiple annular dentation and is formed, and the second corresponding seal groove has multiple annular tooth-like recesses.
The kink of sealing gasket is provided with contact seal sheet, the first seal sticking is in the bottom portion of groove of the first seal groove.
Preferred contact seal sheet preferably adopts the synthetic rubber such as nitrile rubber, acrylate rubber, silicone rubber to make.
On the inner ring that synthetic rubber is suitable for the body one-level ball bearing being bonded in sealing gasket 3 under sulfided state and outer ring.
Preferred further, the first seal sticking is in the recess sidewall of the first seal groove.
Compared with prior art, the utility model adopts sealing gasket to seal ball bearing, and labyrinth sealing end has be bonded and sealed performance more better than gasket seal, and reliability is high, is suitable for bearing and works for a long time in various rugged environment.
The manufacturing deficiency of the direct drinking fountain bearing outer ring edge plagioclase shape of frequent starting in the prior art that the utility model is avoided, directly with the chamfer shape procedure of grinding, simplify manufacturing procedure, change original long angle of internal friction occupying for outer ring fitting area, increase compared to the area of contact between outer ring and bearing mounting bracket, adhesion increases, and is not easy to loosen and slippage.
