Abstract
The utility model discloses a thin-wall ball bearing with dustproof flanges on an outer ring. The thin-wall ball bearing comprises an inner ring (2), the outer ring (3), a working ball (1) and a retainer (4), wherein the outer ring (3) is provided with double dustproof flanges (5); the dustproof flanges (5) and the outer ring (3) have an integrated structure; and a clearance is formed between the dustproof flanges (5) and the corresponding inner ring (2). The outer ring has the double dustproof flanges, and the double dustproof flanges and the outer ring have the integrated structure, so the thin-wall ball bearing not only has a dustproof function, but also can overcome the defects that the dustproof cover of the conventional robot bearing is thin, easy to deform and difficult to machine, the die is expensive, the precision of the bearing is affected and the like.
Description
Technical field
The utility model relates to the thin-walled ball bearing, relates generally to the thin-walled ball bearing of the dustproof rib of a kind of outer astragal, and mostly application is the robot industry.
Background technique
The robot industry is used thin-wall bearing in a large number, the robot own characteristic require bearing in limited space, under the particular surroundings, bearing bears bigger load, can bear tilting moment; Require the robot rotation flexibly, fast.Therefore to its matched robot bearing require it possess thin-walled, in light weight, limit speed is high, bearing capacity is big; And can receive tilting moment; The robot working environment is complicated, and thin-walled, sealing are one of robot characteristics, require bearing to possess dust reduction capability; Prevent that first foreign matter from getting into bearing, influences the working life of bearing; Second prevent that bearing grease from polluting its transhipment, product processed.At present, its structural type of thin-wall bearing that is applied to the robot industry has open type (not having dust cover), two kinds of structures of enclosed (having dust cover).Open architecture does not have dust reduction capability; Existing closed type structure is thin because of the lasso wall, age of a draught animal processing difficulties; The dust cover thin thickness, yielding, processing difficulties, and die cost is high; When dust cover was pressed into lasso, lasso was yielding, and bearing accuracy can be influenced, since the factor of these several respects, its limited use system.
Summary of the invention
The purpose of the utility model provides the thin-walled ball bearing of the dustproof rib of a kind of outer astragal, makes bearing possess dust reduction capability, the variety of issue that solve present closed bearing processing simultaneously, make, assembling occurs.
The purpose of the utility model can adopt following technological scheme to realize: it comprises inner ring, outer ring, work ball and retainer; Both sides, described outer ring are provided with dustproof rib; Dustproof rib and outer ring are structure as a whole, and dustproof rib and corresponding inner ring have the gap.
The two dustproof rib that the described outer ring of the utility model has is structure as a whole with the outer ring, not only has dust reduction capability; And can solve existing robots bearing dustproof cover thin thickness; Yielding, processing difficulties, and die cost is high, bearing accuracy is understood defectives such as influenced.
Description of drawings
Accompanying drawing 2 is bearing outer rings of the dustproof rib of band among Fig. 1.
Among the figure: 1, work ball, 2, inner ring, 3, the outer ring, 4, retainer, 5, dustproof rib.
Embodiment
In conjunction with accompanying drawing, the specific embodiment of the utility model is described:
Shown in accompanying drawing: the thin-walled double-row angular contact bal bearing of the dustproof rib of described overcoat band comprises inner ring 2, outer ring 3, work ball 1 and retainer 4; 3 both sides, described outer ring are respectively arranged with dustproof rib 5; Dustproof rib 5 is structure as a whole with the outer ring; Dustproof rib thickness changes with the size of product size, guarantees that rib has hardness intensity.Dustproof rib 5 has the gap that keeps suitable with corresponding inner ring 2, makes it play the effect dustproof, that bearing grease is excessive.
Claims (1)
1. the thin-walled ball bearing of the dustproof rib of an outer astragal; It comprises inner ring (2), outer ring (3), work ball (1) and retainer (4); It is characterized in that: both sides, described outer ring (3) are respectively arranged with dustproof rib (5); Dustproof rib (5) is structure as a whole with outer ring (3), and dustproof rib (5) has the gap with corresponding inner ring (2).
