Abstract
The completely rolling ball bearing is suitable for being used as single-line centripetal ball bearing and centripetal thrust ball bearing. It consists of inner ring, outer ring, rolling balls, separating rollers distributed intervallically with rolling balls and roller holder. The separating roller has roller inward notch in the middle part and contacts with rolling ball linearly. The roller holder on two sides of the bearing is connected fixedly with the inner ring and fits with the separating rollers at two ends to form the rolling channel. The present invention has the advantages of simple structure, smooth operation, low noise, high limit speed, low power consumption and a long service life. The product of the present invention has standardized inner diameter, outer diameter and width.
Description
The present invention relates to a kind of completely rolling ball bearing, be applicable to single-row radial ball bearing and angular contact ball bearing.
Chinese patent CN1022060 discloses a kind of " pure rolling mother and sons' bearing ", and it is made up of inner ring, outer ring, female rolling element, sub-rolling element and positioning ring device, and the positioning ring device is positioned at the bearing both sides, respectively has towards the positioning ring of the annular lock groove of bearing one side.Sub-rolling element two ends can freely embed in the annular lock groove of each positioning ring.The movement locus of female rolling element symmetry center is a pitch circle, and the movement locus of sub-rolling element symmetry center is exactly above-mentioned pitch circle.The shortcoming of this bearing is a positioning ring apparatus structure complexity, easily produces between sub-rolling element and the positioning ring and slides.
The objective of the invention is at above-mentioned prior art in shortcoming, and provide a kind of simple in structure, running steadily, noise is little, limit speed is high, energy consumption is little, the completely rolling ball bearing of long service life.
The object of the present invention is achieved like this: the separation roller that it includes inner ring, outer ring, ball rolling element, distributes alternately with the ball rolling element, it also includes and isolates the raceway body, separation roller is the roller body that intermediate portion has the circular arc indent, the ball rolling element is that line contacts with separation roller, isolate the both sides that the raceway body is positioned at bearing, and be fixedly connected with inner ring, the two end part that isolate raceway body and separation roller are equipped to form the raceway of separation roller.
The radius of the movement locus of the symmetry center of ball roll body is less than the radius of the movement locus of the symmetry center of separation roller.
The raceway diameter D1 of isolation raceway body equals the maximum diameter d 1 of separation roller and the ratio of minimum diameter d, i.e. D1: D=d1: d with the ratio of the outer raceway minimum diameter D of inner ring.
Isolating raceway body and inner ring is that conical surface drive fit adding additives is bonding.
Working principle of the present invention is by separation roller ball to be rolled to separate, locate, and then by removing to limit the movement locus of separation roller with the synchronous isolation raceway body of inner ring, at the volley, and does pure rolling mutually.Thereby reach the coefficient of reducing friction, the intensification of reducing friction improves the working life of bearing greatly.
Advantage of the present invention be simple in structure, running steadily, noise is little, limit speed is high, energy consumption is little, long service life.
Below in conjunction with drawings and Examples the present invention is further described:
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the left view of Fig. 1.
By Fig. 1-2 as can be known, the separation roller (3) that the present invention includes inner ring (1), outer ring (4), ball rolling element (5), distributes alternately with ball rolling element (5), it is characterized in that it also includes isolation raceway body (2), separation roller (3) has the roller body of circular arc indent for intermediate portion, ball rolling element (5) contacts for line with separation roller (3), isolate the both sides that raceway body (3) is positioned at bearing, and be fixedly connected with inner ring (1), isolate raceway body (2) and the equipped raceway in the two end part of separation roller (3) with the formation separation roller.
The radius of the movement locus of the symmetry center of ball roll body (5) is less than the radius of the movement locus of the symmetry center of separation roller (3).
Isolate the raceway diameter D1 of raceway body (2) and the ratio of the outer raceway minimum diameter of inner ring (1) D and equal the maximum diameter d 1 of separation roller (3) and the ratio of minimum diameter d, i.e. D1: D=d1: d.
Isolating raceway body (2) is that conical surface drive fit adding additives is bonding with inner ring (1).
The effect of separation roller is to have separated the ball rolling element when and then the ball rolling element rolls, and the ball rolling element is limited in the uniform scope, also makes separation roller certainly in axially locating simultaneously.The raceway diameter D1 of isolation raceway body equals the maximum diameter d 1 of separation roller and the ratio of minimum diameter d with the ratio of the outer raceway minimum diameter D of inner ring, and this just can guarantee to reach the purpose of full rolling.
The endoporus of completely rolling ball bearing of the present invention, external diameter, width all meet the existing standard bearing narrow, in, heavy series.
Claims (4)
1, a kind of completely rolling ball bearing, the separation roller (3) that it includes inner ring (1), outer ring (4), ball rolling element (5), distributes alternately with ball rolling element (5), it is characterized in that it also includes isolation raceway body (2), separation roller (3) has the roller body of circular arc indent for intermediate portion, ball rolling element (5) contacts for line with separation roller (3), isolate the both sides that raceway body (3) is positioned at bearing, and be fixedly connected with inner ring (1), isolate raceway body (2) and the equipped raceway in the two end part of separation roller (3) with the formation separation roller.
2, bearing according to claim 1, the radius of movement locus of symmetry center that it is characterized in that ball roll body (5) is less than the radius of the movement locus of the symmetry center of separation roller (3).
3, bearing according to claim 2 is characterized in that isolating the raceway diameter D1 of raceway body (2) and the ratio of the outer raceway minimum diameter of inner ring (1) D equals the maximum diameter d 1 of separation roller (3) and the ratio of minimum diameter d, i.e. D1: D=d1: d.
4, bearing according to claim 3, it is characterized in that isolating raceway body (2) is that conical surface drive fit adding additives is bonding with inner ring (1).
