Abstract
The invention discloses a grating adjusting mechanism, which comprises a rotating shaft and a grating, wherein the rotating shaft is in transmission connection with the grating through a gear transmission system; the gear transmission system comprises a first gear and a second gear which are mutually meshed; the first gear is fixedly connected with the rotating shaft; and the second gear is fixedly connected with the grating. Furthermore, the grating adjusting mechanism further comprises an elastic element used for enabling the first gear and the second gear to be butted tightly along the radial direction. Preferably, the elastic element comprises a tension spring; and two ends of the tension spring are respectively and fixedly connected with the first gear and the second gear. The grating adjusting mechanism has the benefits that on the basis that the structure of a traditional grating mechanism is improved, one gear is pulled to the other gear through additionally arranging the elastic element in the gear transmission system, so that a gap between the gears is eliminated; and by adopting a grating acceleration transmission mechanism, the grid number of the grating is amplified according to the transmission ratio, and further, the resolution ratio of the grating is greatly improved to optimize the use effect and the precision of optical equipment.
Description
Technical field
The present invention relates to a kind of optical device, relate in particular to a kind of grating governor motion that is used for the optical device support.
Background technology
At present, at astronomical telescope, in the equipment such as optical survey appearance, tend to use mensuration and adjusting right ascension axles such as grating sensing mechanism, thereby obtain good accuracy of observation and observation effect.Existing this type of grating sensing mechanism generally is to realize that through adopting high-precision grating and highly sensitive light idol to make up the grid number of grating is many more when using, and the sensitivity of light idol is high more, and the resolution of grating mechanism is just high more, and volume is also just big more.But this high-precision grating is subject to the size of volume and the height and the complicated manufacture craft of cost.In some equipment, in order to obtain higher resolution, it is very big that grating is often done, and this has just increased difficulty and the cost made, does not have practicality and price competitiveness.
Summary of the invention
The present invention aims to provide a kind of grating governor motion, its easy operating, and volume is little, and is cheap, and precision is high, thereby overcome deficiency of the prior art.
For realizing the foregoing invention purpose, the present invention has adopted following technical scheme:
A kind of grating governor motion; Comprise rotating shaft and grating, said rotating shaft is in transmission connection through pinion unit and grating, and said pinion unit comprises intermeshing first gear and second gear; Said first gear is fixedly connected with rotating shaft; Said second gear is fixedly connected with grating, and further, it comprises:
Be used to flexible member that first gear and second gear are radially pushed against.
As one of preferred version, said flexible member comprises extension spring, and said extension spring two ends are fixedly connected with second gear with first gear respectively.
As one of preferred version, said extension spring two ends are fixedly connected with first gear and second gear through back up pad that is associated with first gear and the back up pad that is associated with second gear respectively.
As one of preferred version, the diameter of said first gear is greater than second gear.
Said grating cooperates with light idol.
A kind of optical device is regulated support, and it comprises described in this way grating governor motion.
A kind of optical device, it comprises aforesaid grating governor motion or aforesaid optical device adjusting support.
Compared with prior art, the invention has the advantages that, on the basis that the structure to the grating mechanism that commonly sees changes; Through in pinion unit, setting up flexible member, a gear is pulled to another gear, thereby eliminate the backlash between gear; And employing grating speed booster driving mechanism; The raster grid number is amplified by ratio of gear, and then grating resolution is significantly improved, optimize the result of use and the precision of optical device.

Embodiment
Below in conjunction with an accompanying drawing and a preferred embodiment technical scheme of the present invention is further described.
As one of preferred embodiment; This grating governor motion comprises rotating shaft and grating, and said rotating shaft is in transmission connection through pinion unit and grating, and said pinion unit comprises intermeshing first gear and second gear; Said first gear is fixedly connected with rotating shaft; Said second gear is fixedly connected with grating, and further, this grating governor motion also comprises and is used to flexible member that first gear and second gear are radially pushed against.
Preferably, said flexible member comprises extension spring, and said extension spring two ends are fixedly connected with second gear with first gear respectively.
As one of preferred version, said extension spring two ends are fixedly connected with first gear and second gear through back up pad that is associated with first gear and the back up pad that is associated with second gear respectively.
Obviously, those skilled in the art also can expect adopting other to commonly use flexible member and replace aforementioned extension spring, and obtain close effect by the enlightenment of content of the present invention.
Consulting Fig. 1-3 is a preferred embodiment of the present invention, and this preferred embodiment relates to a kind of astronomical telescope support 1, is connected with lens cone seat 106, grating governor motion etc. on this support 1.
Wherein, this grating governor motion comprises a rotating shaft 100, and this rotating shaft is in transmission connection through a pinion unit and a grating 103; This pinion unit comprises an intermeshing gear wheel 101 and a pinion wheel 102; This gear wheel 101 is fixedly connected with rotating shaft 100, and this pinion wheel 102 is fixedly connected with grating 103, further; Also be provided with extension spring 105 between this gear wheel and the pinion wheel, be used to make gear wheel and pinion wheel radially to push against.These grid 103 cooperate with light idol 104.
By previous designs, present embodiment pulls to gear wheel through extension spring with pinion wheel, thereby can eliminate the backlash between gear wheel and pinion wheel; Adopt the grating speed booster driving mechanism simultaneously, the raster grid number is amplified by ratio of gear, and then promote the resolution and the precision of grating significantly; So; Behind operating personnel's rotating shaft, can make the corresponding rapid movement of the grating that is fixed on the pinion wheel, and cutting light idol signal draws high-resolution precise information.
