Abstract
The vacuum rotating mirror device comprises a direct current motor, a coupling, a gear, a static ring, a moving ring, optical glass and the like, wherein the direct current motor is connected with the gear through the coupling, the gear is installed on a small shaft and meshed with the moving ring, the optical glass is fixed on the moving ring, and the rotating stability is adjusted through a steel ball between the moving ring and the static ring, so that the frictional resistance is reduced. A movable sealing ring is arranged in the movable ring, two layers of O-shaped sealing rings are fixed in the movable sealing ring, and the movable ring and the vacuum box body are sealed by adopting the O-shaped sealing rings. The invention can rotate at a certain rotating speed, and the light uniformly irradiates different positions of the window, so that the window is uniformly heated, the function of avoiding the window from generating a heat effect is achieved, the concentrated heat absorption of the laser is well inhibited, the imaging quality of the optical system is not influenced, and the requirement of the optical system with special requirements is met.
Description
Technical field
The present invention relates to rotating mirror device in a kind of vacuum that is applicable in the specific (special) requirements optical system.
Background technology
Have a lot of equipment to adopt vacuum at present, especially in optical instrument, vacuum is used also very extensive, generally all will use optical window in the optical instrument, is used for propagating light.Requirement to window: the one, satisfy the vacuum seal requirement, the 2nd, satisfy the optical system imaging quality requirement.In general, window is fixed, but some special optical system, when the long-time illumination window of light, because window can not can cause the window glass thermal deformation, thereby influence quality of optical imaging, even cause that window is impaired according to certain rotating speed rotation.
Summary of the invention
Purpose technology of the present invention is dealt with problems and is: a kind of vacuum rotating mirror device is provided, it can be according to certain rotating speed rotation, light is radiated on the diverse location of window equably, window is heated evenly, reduce the window distortion, do not influence simultaneously optical system imaging quality, satisfy the needs of the optical system that specific (special) requirements is arranged.
Technical solution of the present invention is: vacuum rotating mirror device, its characteristics are: it comprises direct current generator, shaft coupling, gear, stationary ring, rotating ring, optical glass, direct current generator is connected with gear by shaft coupling, gear is installed on the little axle, be meshed with rotating ring, fixed optics glass on the rotating ring is adjusted smooth rotation by steel ball between rotating ring and the stationary ring, reduces frictional resistance.
Be provided with rotary packing ring in the rotating ring,, adopt the sealing of O type circle to realize the sealing of rotating ring and vacuum chamber at the two-layer O RunddichtringO of rotary packing ring internal fixation.
The beneficial effect that the present invention compared with prior art has is: because it has the performance of general vacuum window, increase a rotating mechanism of forming by rotating ring, stationary ring etc. on this basis, drive by direct current generator, the rotation of realization vacuum window, therefore it can suppress the concentrated thermal absorption of laser well, satisfies the optical system of some specific (special) requirements.Be on general optical window, to increase rotating mechanism,, make it, have the function of avoiding window to produce thermal effect by certain rotating speed rotation by regulating the input voltage of direct current torque motor.
Description of drawings
Fig. 1 is a section of structure of the present invention.
Embodiment
As shown in Figure 1, present embodiment is by direct current generator 1, shaft coupling 2, gear 3, little axle 4, vacuum chamber 5, rotary packing ring 6, O RunddichtringO 7, stationary ring 8, rotating ring 9, compositions such as microscope base 10 and optical glass 11, direct current generator 1 is by shaft coupling 2 driven gears 3, gear 3 is installed on the little axle 4, drive rotating ring 9 by gearing mesh, fixing microscope base 10 on the rotating ring 9, dress optical glass 11 in the microscope base, the two-layer O RunddichtringO 7 of rotary packing ring 6 internal fixation, realize rotating ring vacuum seal with two-layer O RunddichtringO, by the stationarity of two groups of steel ball adjustment rotations, whole rotating mirror device is connected with vacuum chamber 5 between rotating ring 9 and the stationary ring 8.Direct current generator 1 is adjusted rotating speed of motor by direct supply control by adjusting input voltage, is transferred to desired rotating speed.
