Abstract
The invention discloses a rotation device base which comprises a base body, wherein a fixing block is fixed on the base body. The rotation device base is characterized in that open through holes are formed in the fixing block from the top down, openings are formed in the surface of the fixing block, and each open through hole is a three-quarter cylindrical accommodating chamber. When a rotation structure is located at the top or in the middle of a rotating shaft, the bottom of the rotating shaft can be inserted into the open through holes, during rotation, the rotating shaft can be limited in the three-quarter cylindrical accommodating chambers; the through holes have openings, so that the contact area with the rotating shaft is reduced, and friction and loss are reduced; and besides, the open through holes have certain heights, accordingly, the stress of the rotating shaft is balanced, and centralized stress at a certain part is avoided.
Description
Technical field
The present invention relates to a kind of whirligig base.
Background technique
The rotational structure of whirligig can be arranged on the bottom of running shaft, top or neutral position, and the rotation by rotating machinery drives the rotation of running shaft, the position difference of rotational structure, corresponding whirligig base also is not quite similar.Such as, when rotational structure was positioned at the top of running shaft or neutral position, base should arrange corresponding placement running shaft bottom and for the cavity volume of bottom rotation; When rotational structure was positioned at the bottom of running shaft, base should arrange corresponding whirligig for the rotational structure rotation; The needs that different running shafts has pass then not needing that base has; Running shaft friction with base in the process of rotation is very big, loss is serious ... Given this, the present invention is directed to existing whirligig base and improve, with the demand of the rotational structure that adapts to diverse location, reduce friction and loss in the rotary course, increase the working life of device.
Summary of the invention
The object of the present invention is to provide a kind of whirligig base with the demand of the rotational structure that adapts to diverse location, reduce friction and loss in the rotary course, increase the working life of device.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the present invention is achieved through the following technical solutions:
A kind of whirligig base comprises the base body, at the base body fixed block is arranged fixedly, it is characterized in that, described fixed block is provided with open hole from top to bottom, and opening is positioned at the surface of fixed block, and open hole is four/three cylindrical body cavity volume.
When rotational structure is positioned at the top of running shaft or neutral position, the bottom of running shaft can be inserted in the open hole, in the time of rotation, running shaft can be limited in four/three cylindrical body cavity volume, because through hole has opening, reduced the area of contact with running shaft, and then reduced friction and reduced loss, in addition, open hole has certain height, balance running shaft stressed, it is stressed to avoid a certain position to concentrate.
Further, be positioned at running shaft bottom needs in order to satisfy rotational structure, the whirligig base also comprises several support platforms, and support platform is fixed by screw and base body, support platform is provided with through hole one and rotational structure, and rotational structure links to each other with the running shaft bottom and can realize rotatablely moving.Running shaft also can pass through hole one.When the rotational structure of a support platform was scrapped, the rotational structure that can change other support platform used and does not need whole device all to scrap.
Further, the base body is provided with through hole two.Running shaft can pass through hole two and be connected with miscellaneous part.
Further, the base body is provided with blind hole.When the speed of rotation hour, the bottom of running shaft can be inserted in the blind hole, do not need to increase supernumerary structure and running shaft can be limited in and prevent the position skew in the blind hole.
The invention has the beneficial effects as follows: the whirligig base can adapt to the demand of the rotational structure of diverse location, reduces friction and loss in the rotary course, increases the working life of device.
Description of drawings
Fig. 1 is the structural drawing of a kind of whirligig base of the present invention;
The mark implication of accompanying drawing is as follows:
1: the base body; 2: fixed block; 3: open hole; 4: support platform; 5: rotational structure; 6: through hole one; 7: screw; 8: through hole two; 9: blind hole.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment technical solution of the present invention is described in further detail, can be implemented so that those skilled in the art can better understand the present invention also, but illustrated embodiment is not as a limitation of the invention.
As shown in Figure 1, a kind of whirligig base comprises base body 1, at base body 1 fixed block 2 is arranged fixedly, and fixed block 2 is provided with open hole 3 from top to bottom, and opening is positioned at the surface of fixed block 2, and open hole 3 is four/three cylindrical body cavity volume.When rotational structure is positioned at the top of running shaft or neutral position, 3 li of open hole can be inserted in the bottom of running shaft, in the time of rotation, running shaft can be limited in four/three cylindrical body cavity volume, because through hole has opening, reduced the area of contact with running shaft, and then reduced friction and reduced loss, in addition, open hole 3 has certain height, balance running shaft stressed, it is stressed to avoid a certain position to concentrate.Further, be positioned at running shaft bottom needs in order to satisfy rotational structure, the whirligig base also comprises several support platforms 4, support platform 4 is fixing with base body 1 by screw 7, support platform 4 is provided with through hole 1 and rotational structure 5, and rotational structure 5 links to each other with the running shaft bottom and can realize rotatablely moving.Running shaft also can pass through hole 1.When the rotational structure 5 of a support platform 4 was scrapped, the rotational structure that can change other support platform used and does not need whole device all to scrap.Further, base body 1 is provided with through hole 28.Running shaft can pass through hole two and be connected with miscellaneous part.Further, base body 1 is provided with blind hole 9.When the speed of rotation hour, the bottom of running shaft can be inserted in the blind hole 9, do not need to increase supernumerary structure and running shaft can be limited in and prevent the position skew in the blind hole 9.
The whirligig base of this structure can adapt to the demand of the rotational structure of diverse location, reduces friction and loss in the rotary course, increases the working life of device.
Below only be the preferred embodiments of the present invention; be not so limit claim of the present invention; every equivalent structure or equivalent flow process conversion that utilizes specification of the present invention and accompanying drawing content to do; perhaps directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
