Abstract
The utility model discloses a ball-column embedding-type revolving support which is composed of an outer seat ring, an inner seat ring, a roller and a steel ball. The inner seat ring and the outer seat ring are respectively provided with a horizontal straight line-shaped rolling path and a spherical rolling path, the roller is positioned in the horizontal straight line-shaped rolling path, and the steel ball is positioned in the spherical rolling path. The roller which is placed horizontally is utilized to bear the axial force, the steel ball is utilized to bear the radial force, and the roller and the steel ball are utilized to bear the turnover force moment together. When the ball-column embedding-type revolving support is used, the relatively large axial force can be borne, and the definite turnover force moment and the definite radial force can be borne simultaneously; in addition, the utility model has the advantages of small section size and low cost.
Description
The utility model relates to a kind of pivoting support.
Supporting rolling element in the existing pivoting support, or be roller, or be steel ball.It is enough and sectional dimension is big and the more high phenomenon of cost that bearing capacity deficiency, bearing capacity in use often appear in this pivoting support, this use to pivoting support brings certain restriction (see " pivoting support) " Xu Limin, Chen Zhuofang work, Anhui science tech publishing house publishes, in December, 1988).
The purpose of this utility model is that a kind of goalpost combined type pivoting support will be provided, and the bearing capacity of this pivoting support is big and sectional dimension is little and cost is low.
The purpose of this utility model is achieved in that this pivoting support mainly is made up of outer race, inner race, roller and steel ball, inner race and outer race respectively have a linear raceway of straight horizontal and a ball-track, roller is positioned at the linear raceway of straight horizontal, and steel ball is positioned at ball-track.
Described ball-track is the semicircle raceway of single ditch.
Be an angle between the carrying direction of described steel ball and the horizontal plane, angle is 0～90 degree.
The utility model bears axial force by the roller of horizontal positioned, and radial force is born by steel ball, and tilting moment is born jointly by both.Can bear larger axis to power, it is less that the while can be born certain tilting moment and radial force and sectional dimension again, and cost of production is low.
Elaborate below in conjunction with drawings and Examples.
Accompanying drawing is an an embodiment's of the present utility model structural drawing.
1. outer races among the figure, 2. roller, 3. steel ball, 4. inner race.
In the accompanying drawings, outer race 1 is enclosed within inner race 4 outsides, and a straight horizontal shape line raceway is all arranged at inner race 4 and outer race 1 top, and roller 2 is positioned at this two raceways.A ball-track is also respectively arranged at inner race 4 and outer race 1 bottom, and ball-track is the semicircle raceway of single ditch, and steel ball 3 is positioned at this two raceways.The carrying direction of roller 2 is vertical with last lower plane, and the carrying direction of steel ball 3 and the angle α between the horizontal plane are 45 degree.Angle α is according to stressed combined situation, and axle, radial clearance when can not pack roller into by control are adjusted.Angle α can change in o～90 degree scopes.
Claims (3)
1, a kind of goalpost combined type pivoting support, this pivoting support mainly is made up of outer race, inner race, roller and steel ball, it is characterized in that inner race and outer race respectively have a linear raceway of straight horizontal and a ball-track, roller is positioned at the linear raceway of straight horizontal, and steel ball is positioned at ball-track.
2, goalpost combined type pivoting support according to claim 1 is characterized in that ball-track is the semicircle raceway of single ditch.
