The utility model discloses simple structure has changed original shield, has solved the technical problem among the prior art.
Description
Technical Field
The utility model relates to a bearing field especially relates to a high-speed ball bearing.
Background
The ball bearing is a very common mechanical part, a dustproof cover is generally arranged between an outer ring and an inner ring of the ball bearing, the joint of the existing dustproof cover and the outer ring is generally a curled edge cover, the gland process of the curled edge cover is that a mould is pushed by air pressure to extrude the curled edge position of the dustproof cover into a dustproof groove of the outer ring, and the outer diameter ovality of a product is increased due to overlarge curled edge extrusion of the dustproof cover when the air pressure is overlarge, so that the quality of the bearing is influenced; and the problem that the dust cover is not extruded in place due to too small air pressure, so that the dust cover is loosened and the like is caused, so that improvement is needed.
SUMMERY OF THE UTILITY MODEL
The utility model provides a high-speed ball bearing, simple structure has changed original shield, has avoided foretell technical problem.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a high-speed ball bearing, includes bearing inner race and bearing inner race, bearing inner race and bearing inner race between be provided with the steel ball, the steel ball outside install the holder, bearing inner race and bearing inner race between both sides embedding install the shield, the shield include the supporting part and be located the dependence portion in the radial outside of supporting part, dependence portion hug closely with the bearing inner race, the upper end of dependence portion be provided with hem portion, the both ends of the inside wall of bearing inner race all be provided with the dust proof groove, hem portion's tip and dust proof groove inside wall withstand.
Preferably, the dustproof groove comprises an arc part and an inclined plane part, and the end part of the folded edge part is propped against the inclined plane part.
Alternatively, the leaning part is connected with the supporting part through a bevel transition part.
Preferably, the two ends of the outer circumferential side wall of the bearing inner ring are provided with inner clamping grooves, and the lower end of the supporting part is provided with a clamping end embedded into the inner clamping grooves.
Compared with the prior art, the beneficial effects of the utility model are that:
simple structure has changed original shield, replaces original hem portion with hem portion, utilizes the elastic deformation card of stainless steel material to advance the effect that the dust proof tank reached fixed shield, and its elasticity is used and can not cause the problem of ovality to the bearing, and mounting process is simple reliable.

fig. 2 is an enlarged view of a part of the structure of the present invention.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1-2, the utility model provides a high-speed ball bearing, including bearing inner race 1 and bearing inner race 2, bearing inner race 1 and bearing inner race 2 between be provided with steel ball 7, the steel ball 7 outside install holder 3, bearing inner race 1 and bearing inner race 2 between both sides embedding install shield 4, shield 4 include supporting part 11 and the dependence portion 5 that is located the 11 radial outsides of supporting part, dependence portion 5 hug closely with bearing inner race 1, the upper end of dependence portion 5 be provided with hem portion 6, the both ends of bearing inner race 1's inside wall all be provided with dust proof groove 8, hem portion 6's tip and dust proof groove 8 inside wall withstand.
Hem portion 6 has certain elasticity, directly impresses in dust-proof groove 8 withstands with the inside wall in the installation, just can realize shield 4's joint, impresses and need not the mould, and general frock just can.
The relying part 5 is used for leaning against the bearing outer ring 1 and can play a role in limiting and supporting in clamping connection, the supporting part 11 is at a distance from the bearing outer ring 1, one space is enough for lubricating the steel balls 7, and the two support strengths are good for the dust cover 4.
As a specific embodiment of the dust-proof groove 8, the dust-proof groove 8 includes an arc portion and an inclined portion 12, the end of the folded portion 6 abuts against the inclined portion, and a cross-sectional angle between the inclined portion and the folded portion 6 is generally greater than 60 °, so that the folded portion 6 cannot easily slide along the inclined portion.
In order to further improve the strength of the dust cover 4, the depending portion 5 is connected with the supporting portion 11 through a slope transition portion 13.
Be located and carry on spacingly to the inboard side of shield 4, the both ends of the outer circumference lateral wall of bearing inner race 2 be provided with interior draw-in groove 10, the lower extreme of supporting part 11 be provided with the screens end 9 of embedding in draw-in groove 10, interior draw-in groove 10 generally is the arc recess, makes things convenient for screens end 9 card to go into.
While the invention has been described above with reference to an embodiment, various modifications may be made and equivalents may be substituted for elements thereof without departing from the scope of the invention. In particular, as long as there is no structural conflict, the various features of the disclosed embodiments of the present invention can be used in any combination with each other, and the description of such combinations is not exhaustive in the present specification only for the sake of brevity and resource conservation. Therefore, it is intended that the invention not be limited to the particular embodiments disclosed, but that the invention will include all embodiments falling within the scope of the appended claims.
