Abstract
The utility model relates to a ball bearing, comprising an inner ring, an outer ring and a middle ring. An inner roller path formed between the inner ring and the outer ring and an outer roller path formed between the outer ring and the middle ring are respectively provided with balls and a holder. The structural characteristics can be applied to various ball bearings in order to form double-structural serial products of the ball bearing, the double-structural ball bearing has low friction coefficient and high limit speed, and the ball bearing is a new ball bearing with extensive applicable foreground.
Description
The utility model relates to a kind of ball bearing.
Known ball bearing is assembled by inner ring, outer ring, ball and retainer, improve the limit speed of this structure ball bearing, not outer at present the employing such as improving precision, increase play, improve material, strengthening technical measures such as lubricated, but these technical measures do not relate to the substantial improvements of bearing structure.
The purpose of this utility model provides the ball bearing of the high new structure of a kind of limit speed.
Solve key of the present utility model and be between the inner ring of bearing and outer ring centre circle is set, form inner ring with the interior raceway between the centre circle and in the outer ring with the outer raceway between the centre circle, be equipped with ball and retainer in interior raceway and the outer raceway.
Accompanying drawing is a structure diagram of the present utility model.
1. inner rings among the figure; 2. outer ring; 3. centre circle; 4. interior raceway; 5. outer raceway; 6 and 8. balls; 7 and 9. retainers.
Obviously, above-mentioned architectural feature not only can be applicable on the single-row radial ball bearing, also can be applicable on biserial double row self aligning ball bearings and the single row angular contact ball bearing, forms double-deck ball bearing series.
The known ball bearing of the load ratio same size that every ball of this double-decker ball bearing bears is little, coefficient of friction is low, the bearing limit speed can improve, and therefore, the utility model is a kind of ball bearing with new construction of wide application prospect.
Claims (1)
