Be provided with the inner annular recess at the bottom of the annular circular arc in the outer ring on the circle, the position of inner annular recess and outer annular recess is corresponding, at the bottom of the circular arc of inner annular recess and the steel ball external diameter adaptive, outer ring outer wall upper edge radially is provided with cylindrical bar;
Steel ball is uniformly distributed with array on the retainer circumference, and with interior ring outer wall on outer annular recess and outer ring in inner annular recess on the circle closely contact, make inner ring outside encircled energy easily rotate.
As the additional and optimization to technique scheme, the present invention also comprises following technical characteristics: outer ring outer wall upper edge radially is provided with several cylindrical bars, can be 2 or more, and the needs that adapt to mechanical motion dispose suitable radical.
Outer annular recess at the bottom of several annular circular arcs has laterally arranged on the outer wall of inner ring stage casing; Inner annular recess at the bottom of several annular circular arcs has also laterally arranged on the circle in the outer ring; The shape and the spacing of inner annular recess and outer annular recess are adaptive, all are provided with adaptive steel ball and retainer between corresponding outer annular recess and the inner annular recess; The Driving force that can increase the outer ring cylindrical bar is set like this reaches 4 times, be specially adapted to many rod bearings.
In the middle of the inner ring through hole and step are arranged, be convenient to be fixed in the equipment rotating shaft of transmitting torque.
Both ends of the surface in the outer ring are provided with seal ring, prevent that dust from invading and internal lubrication fat leaks.
The invention has the beneficial effects as follows: if on the cylindrical bar of outer ring, be provided with the slideway parallel with inner ring axis; Then work as inner ring when rotated; Can drive the back and forth translation in slideway of outer ring cylindrical bar, thereby cylindrical bar can drive the vibration member frequent vibration of equipment, the design of the axis through cylindrical bar length or annular groove and the axis crossing angle of interior ring through hole; Can control the translation stroke on cylindrical bar top; Rotating speed design through inner ring can be controlled vibration frequency, and is applied widely, can realize our needed multiple function.Compact structure of the present invention, the use heating is little continuously, power consumpiton is low, be convenient to installing/dismounting and maintenance, precision is high, rotating speed is fast, can bear big load, reliable performance, long service life.

Embodiment
Through accompanying drawing and embodiment the present invention is done further to set forth in detail below.
The structure of the two rod bearings of biserial that vibrating machine is special-purpose such as Fig. 1 are to shown in Figure 5, and outer ring 2 oblique being enclosed within on the inner ring 1 have been installed steel ball 3 and retainer 4 in the outer ring 2, and the steel ball 3 that array is uniformly distributed with has pushed against the inner annular recess 2-1 of outer ring and the outer annular recess 1-1 of inner ring.
The axis of the axis of outer groove 2-1 and interior ring through hole 1-2 is not parallel, and the crossing angle of present embodiment is 9.6 degree.
The cylindrical bar 2-2 of present embodiment is 2, symmetric arrays; Radical and position, the length of cylindrical bar 2-2 can be set arbitrarily according to the equipment needs.
As shown in Figure 4; Outer annular recess 1-1 at the bottom of two annular circular arcs has laterally arranged on the inner ring 1 stage casing outer wall of present embodiment; Inner annular recess 2-1 at the bottom of several annular circular arcs has also laterally arranged on the circle in the outer ring 2; Shape and the spacing of outer annular recess 1-1 and inner annular recess 2-1 are adaptive, all are provided with adaptive steel ball 3 and retainer 4 between corresponding outer annular recess 1-1 and the inner annular recess 2-1.
When if the cylindrical bar 2-2 quilts above the outer ring 2 have been placed restrictions on freedom of movement with the slideway of inner ring 1 parallel axes, during inner ring 1 rotation, cylindrical bar 2-2 can to-and-fro motion in slideway, drives other equipment parts vibrations that are connected above the cylindrical bar 2-2.Two cylindrical bar 2-2 of present embodiment can bring into play different effects, and for example a cylindrical bar 2-2 promotes the vibration member impact, and other one then connects with brake, realizes intermittently impact; The such equipment of hard and infertile hard and infertile plate that also can promote similar kindergarten is swung one on the other, perhaps flaps as the wing of model penguin.
Single-row pair of rod bearing as shown in Figure 6, basic structure is identical with embodiment 1, only is to be provided with through hole 1-2 with the level in the middle of the inner ring 1, is used to install the axial workpiece of transmitting torque; And the biserial steel ball is reduced to row, is applicable to the equipment that load is lighter, because manufacture difficulty greatly reduces, so cost is low.
Single-row single pole bearing as shown in Figure 7, basic structure is identical with embodiment 2, only is that the cylindrical bar on the outer ring only is provided with one, and manufacture cost is lower, is applicable to conventional equipment uses such as electric hammer.
The above is merely one embodiment of the present of invention, is not the restriction to this case design, and all multiple combination and variation of doing according to the design key of this case all fall into the protection domain of this case.
