Such as in the mechanical mechanism of plunger pump machanism, piston mechanism rotation and up-and-down motion, for alternative plunger pump, piston
Etc. the device for moving back and forth, and running accuracy is high, stability is strong, long lifespan.
Brief description of the drawings
Fig. 1 is a kind of knot for rotating composite bearing one preferred embodiment integrated with up-and-down motion of the present invention
Structure schematic diagram；
The mark of each part is as follows in accompanying drawing：1st, the first outer ring, 2, inner ring, the 3, first rolling element, the 4, first retainer, 5, second
Outer ring, the 6, second rolling element, the 7, second retainer.
Specific embodiment
Presently preferred embodiments of the present invention is described in detail below in conjunction with the accompanying drawings, so that advantages and features of the invention energy
It is easier to be readily appreciated by one skilled in the art, apparent is clearly defined so as to be made to protection scope of the present invention.
Fig. 1 is referred to, the embodiment of the present invention includes：
A kind of rotation composite bearing integrated with up-and-down motion, including：First outer ring 1, inner ring 2, the second outer ring
5th, the first retainer component and the second retainer component；The first retainer component is by the first retainer 4 and installed in described
The first rolling element 3 in the pocket hole of the first retainer 4 is constituted；The second retainer component is by the second retainer 7 and is arranged on
The second rolling element 6 in the pocket hole of second retainer 7 is constituted；First outer ring 1, the first retainer component and inner ring 2
A journal bearing is constituted, pure rotational motion can be formed；Second outer ring 5, the second retainer component and inner ring 2 constitute a thrust
Bearing, can form left and right directions（In shown in Fig. 1）Reciprocating motion；The roller surface that the inner ring 2 matches with second outer ring 5
Containing an inclination angle, in the present embodiment, the inclination angle is 15 °.
During work, the first outer ring 1 is installed and is maintained static, and inner ring 2 is rotated by drive shaft, after inner ring 2 rotates, outside second
The and then rotary motion of circle 5, while because inner ring right side roller surface is provided with an angle（The rolling that i.e. 2 and second outer ring of inner ring 5 matches
Inclination angle on road face）, so, while rotation, each point on its face has the reciprocal fortune of one or so for the second outer ring 5
It is dynamic, so as to realize that rotation is integrated with up-and-down motion；By adjusting the angle at the inclination angle, can control reciprocal
The amplitude of motion.
