Abstract
The utility model provides a kind of rotator type eccentric sphere, including sphere and a rotor, be relatively fixed portion there are two being set in the sphere, each fixed part is equipped with card slot, the rotor one end is set there are two opposite protrusion, the protrusion is rotatably dispose on the card slot, and the rotor length is less than the radius of sphericity, is explained convenient for teacher.
Description
Technical field
The utility model is related to a kind of eccentric spheres, refer in particular to a kind of rotator type eccentric sphere.
Background technology
In existing teaching, when the ball that barycenter and geometric center overlap is thrown into ground by user, the movement locus of ball is day
The track usually seen is approximately parabola, is known from；But barycenter and geometric center are misaligned, the barycenter of ball is still thrown
The movement of object line tracking, but since geometric center is not overlapped with barycenter, the appearance of ball can be superimposed rotation on parabolical track
Transhipment is dynamic, but due to the stage property of no this demonstration, only allows student by the imagination so that a part of student can not understand, unfavorable
The explanation of Yu teacher.
Invention content
The technical problems to be solved in the utility model is to provide a kind of rotator type eccentric sphere, be explained convenient for teacher.
The utility model is realized in this way：A kind of rotator type eccentric sphere, including sphere further include a rotor, the ball
It is set in vivo there are two being relatively fixed portion, each fixed part is equipped with card slot, and the rotor one end sets that there are two opposite
Protrusion, the protrusion is rotatably dispose on the card slot, and the rotor length is less than the radius of sphericity.
Further, described rotor the other end is equipped with swivel.
Further, the rotor is V-shape or T fonts.
The utility model has the advantage of：A kind of rotator type eccentric sphere of the utility model can be with when teacher explains
It is demonstrated by the eccentric sphere so that student is easier to understand.
Description of the drawings
The utility model is further described in conjunction with the embodiments with reference to the accompanying drawings.
Fig. 1 is a kind of structural schematic diagram of rotator type eccentric sphere of the utility model.
Specific implementation mode
Refering to Figure 1, the utility model rotator type eccentric sphere, including sphere 1 and a rotor 2, in the sphere 1
If there are two the portion 11 that is relatively fixed, each fixed part 11 is equipped with card slot (not shown), and 2 one end of the rotor is set
There are two opposite protrusion 21, the protrusion 21 is rotatably dispose on the card slot, and 2 length of the rotor is less than the ball
1 radius of body, 2 the other end of the rotor are equipped with swivel 22, and swivel 22 could be provided as wedge shape so that reduce air in rotation
Resistance, and allow the rotation in sphere 1 that rotor 2 is more prone to, the rotor 2 are V-shape or T fonts, by
Bearing 12 is set on card slot, and bearing 12 is fastened on card slot, the protrusion 21 of rotor 2 is arranged in bearing 12 later so that
It can the rotation in sphere 1.
When in use, eccentric sphere being rotated in the hand so that rotor 2 therein rotates, and sphere 1 is dished out later,
So that during sphere 1 makees parabolic motion, sphere 1 itself is also rotating.
The sphere 1 includes two spherical shell (not shown), and two spherical shell connection types are：One spherical shell connection edge has convex
The ring risen, it is glued with another half-shell annular recess.
Although the foregoing describe specific embodiment of the present utility model, those familiar with the art answers
Working as understanding, we are merely exemplary described specific embodiment, rather than for the limit to the scope of the utility model
Fixed, those skilled in the art modification and variation equivalent made by the spirit according to the utility model all should
Cover in the scope of the claimed protection of the utility model.
Claims (3)
1. a kind of rotator type eccentric sphere, including sphere, it is characterised in that：Further include a rotor, is set in the sphere there are two phase
To fixed part, each fixed part is equipped with card slot, and the rotor one end sets that there are two opposite protrusions, described prominent
The portion of rising is rotatably dispose on the card slot, and the rotor length is less than the radius of sphericity.
2. a kind of rotator type eccentric sphere as described in claim 1, it is characterised in that：Described rotor the other end is equipped with swivel.
3. a kind of rotator type eccentric sphere as described in claim 1, it is characterised in that：The rotor is V-shape or T fonts.
