Detailed description of the invention
Hereinafter, with reference to accompanying drawing, detailed description of the invention of the present utility model is illustrated.In the following description, identical accompanying drawing labelling is enclosed for same key element, and sometimes omits detail explanation.
Fig. 1 is the three-dimensional exploded view of the gravity governor motion 1 of present embodiment.
As it is shown in figure 1, gravity governor motion 1 possesses matrix 11, rotor 12, gravitation ball 13 and lid 14.
Hereinafter, based on 1～4 pair of matrix 11 of accompanying drawing, rotor 12, gravitation ball 13 and lid 14.Illustrate.
Fig. 2 is the axonometric chart of matrix 11.
As shown in Fig. 1～2, the position that the inner cylinder face at matrix 11 with rotor 12 contacts, in order to reduce frictional force by minimizing friction area, it is provided with 5 fins.
This fin may not be 5, as long as more than 3.
Fig. 3 is the axonometric chart of rotor 12.
As shown in Figure 1, Figure 3, rotor 12 is made up of disk 121 and 6 ribs 122 of center sky.Wherein, 4 ribs 122 below become grid, bear the power of gravitation ball 13.The front end of 6 ribs 122 abuts with the face of lid 14, thus, and the degree of freedom axially of restriction rotor 12.
It addition, in figure 3, rotor 12 gravity direction be provided above opening, but according to circumstances can also be not provided with this opening.
Further, in order to reduce friction, this rotor 12 is designed to as far as possible light.
Fig. 4 is the axonometric chart of lid 14.
As Figure 1 and Figure 4, lid 14 has the first face 141 and the second face 142, and this first face 141 is the face of cylinder, the degree of freedom on the radial direction of rotor 12 of restriction gravitation ball 13, this second face 142 abuts with the front end of the rib 122 of rotor 12, the degree of freedom axially of restriction rotor 12.
It addition, the function of lid 14 is while the degree of freedom of restriction rotor and gravitation ball, become conduit.In the lid 14, the first wind entrance 143 and the second wind entrance 144 it is additionally provided with.
This first wind entrance 143 and the second wind entrance 144 are for directing wind into by the space formed by lid 14, rotor 12 and matrix 11.
As required, it is also possible to be not provided with this first wind entrance 143 and the second wind entrance 144, it is also possible to the wind entrance of or more than three is set.
As shown in Figure 1,3 gravitation balls 13 are placed in 3 grid that 4 ribs 122 below by rotor 12 are formed.
Material as gravitation ball 13, it is possible to enumerate steel or lead, it is also possible to be the material that other density is high.
It addition, the quantity of gravitation ball 13 is not limited to this, it is also possible to change its quantity according to practical situation.
Further, the gravity governor motion 1 of present embodiment is installed on the chiller of scialyscope, for the lamp etc. of scialyscope is cooled down.
Hereinafter, the operation principle of the gravity governor motion 1 of present embodiment is illustrated.
Matrix 11 and lid 14 are fixed by 2 screws, and both are fixed on scialyscope together.The relative position of matrix 11, lid 14 and scialyscope three is constant.
The wind that the lamp of scialyscope is cooled down needs to blow from top to bottom on gravity direction.When scialyscope rotates along trunnion axis, it is necessary to the opening of rotor 14 and the relative position of the earth remain constant.
When scialyscope rotates along trunnion axis, matrix 11 rotates together with scialyscope with lid 14, when rotated, produces the frictional force of matrix 11 and rotor 12, and the existence of this frictional force makes rotor 12 have the tendency of rotation.
In the present embodiment, it is arranged in 3 grid being made up of 4 ribs 122 by 3 gravitation balls 13, the component of the horizontal direction of the gravity of gravitation ball 13 hinders the rotation of rotor 12, it is possible to prevent the rotation of rotor 12, the opening of rotor 12 to be always maintained at towards the top on gravity direction.
Now, the function of lid 14 is the motion axially of restriction rotor 12 and limits the motion on the radial direction of gravitation ball 13, becomes the conduit of transmission wind simultaneously.
It is arranged on which direction and is all located at the opening of rotor 12 of top of gravity direction it is to say, no matter scialyscope can be passed through from the wind of lid 14 entrance and is passed to matrix 11.
According to this gravity governor motion 1, rotor 12 can be designed to lighter, it is possible to makes to be set to minimum with the frictional force of matrix 11, improves the precision that position keeps.
Additionally.If gravitation ball 13 is integrated with rotor 12, then the gravity of rotor 12 becomes big, and friction also becomes big, and result rotor 12 rotates together with matrix 11.
The constituent part of this gravity governor motion 1 is few, and design freedom is high, it is not necessary to gravity sensor, cost is low.
Fig. 5 is the axonometric chart of the scialyscope possessing above-mentioned gravity governor motion 1.
Hereinafter, the example possessing the different setting directions of the scialyscope of above-mentioned gravity governor motion 1 is described with reference to Fig. 5.
In fig. 5, scialyscope is arranged upward, and in figure 5b, the setting direction of scialyscope is contrary with Fig. 5 A, is set to arrange down.
Scialyscope lamp cooling air needs to blow from top to bottom, i.e. the opening of rotor 12 needs to remain towards the top on gravity direction.
Because the gravitational high of gravitation ball 13, so the lower section remained on gravity direction, the relative position of rotor 12 and gravitation ball 13 does not change, and the opening of rotor remains at the top on gravity direction.
Wind is through the space formed by lid, rotor and matrix, and opening from above blows to the bulb of lamp.
Above, specific embodiment for a kind of gravity governor motion of the present utility model and the scialyscope that comprises this gravity governor motion is illustrated, but this utility model is not limited to this, it is possible to carry out various change on the basis without departing from purport of the present utility model.
