Abstract
The utility model discloses a structure of a sine mechanism adjusting device. The existing installation driving of gear mesh of dispersion parts is changed to the integration structure of a motor and a screw rod. A shaft of the screw rod and the motor can realize flexible transition butt joint by a torsion spring of a shaft coupling. The output of the motor can be effectively transferred to the screw rod of a sine mechanism by the flexibility of the torsion spring. Thereby, the utility model can normally rotate and move, and has the advantage of convenient installation, adjustment and operation. The utility model can realize low-noise and high-precision transport, and the whole performance can be enhanced largely.
Description
Technical field
The utility model relates to a kind of wavelength adjusting gear of surveying instrument, specifically a kind of sine mechanism adjusting gear.
Background technology
The sine mechanism adjusting gear comprises screw mandrel and motor, drives screw mandrel at present and rotates employing gear or synchronous pulley transmission mostly, screw mandrel is produced rotatablely move accordingly.Yet the gear structure transmission is big, the low precision of noise often; The transmission of synchronous pulley structure then is that band is easily aging lax synchronously, causes the poor repeatability of instrument.
Summary of the invention
The purpose of this utility model provides sine mechanism adjusting gear a kind of simple in structure, reliable, so that effectively reduce noise, prolongs the serviceable life of instrument.
For finishing the technical scheme that above-mentioned purpose adopts be: a kind of sine mechanism adjusting gear of forming by screw mandrel, motor, support etc., it is characterized in that: motor docks by the shaft coupling flexible transition with screw mandrel, described shaft coupling is made up of a torsion spring and two coupling bands that are installed in torsion spring two ends respectively, screw axis and motor shaft insert respectively in the flat hole of two coupling bands, middle by the torsion spring transition, make motor and parts relative fixed composition one such as screw mandrel, shaft coupling by support again.
The beneficial effects of the utility model are installation, adjustment, easy to operate, are installed by former dispersion part gearing mesh to drive, and become motor and screw mandrel integral structure, thereby realize low noise, high precision conveying, and instrument is improved a lot on overall performance.
Description of drawings
Below in conjunction with accompanying drawing, the utility model sine mechanism adjusting gear is described further.
Fig. 1 sine mechanism adjusting gear structural representation;
The vertical view of Fig. 2 Fig. 1.
Among the figure, the 1-base; The 2-screw mandrel; The 3-coupling band; The 4-bolster; The 5-support; The 6-stepper motor; The 7-coupling band; The 8-torsion spring.
Embodiment
As shown in the figure, a kind of sine mechanism adjusting gear, comprise screw mandrel 2, bolster 4, support 5, stepper motor 6, be characterized in screw mandrel 2 by shaft coupling torsion spring 8 and be installed in stepper motor 6 projecting shaft flexible transition butt joint on the support 5, the coupling band 3 and 7 that shaft coupling is installed on torsion spring 8 two ends by torsion spring 8, is respectively formed, and 2 of screw mandrels place the flat hole of coupling band 3; Motor 6 main shafts place the flat hole of coupling band 7, fixedly form the sine mechanism adjusting gear by bolster 4.When stepper motor 6 rotates, flexibly connect by torsion spring on the shaft coupling 8, be delivered to screw mandrel 2, screw mandrel 2 and stepper motor 6 are rotated synchronously.So it is, easy to operate as long as control step motor 6 just can be controlled the direction of motion of screw mandrel 2.
Claims (2)
1, a kind of sine mechanism adjusting gear comprises screw mandrel (2) and motor (6), it is characterized in that: the axle of described screw mandrel (2) and motor (6) is by torsion spring (8) the flexible transition butt joint of shaft coupling.
2, according to the described sine mechanism adjusting gear of claim 1, it is characterized in that: coupling band (3) and (7) that described shaft coupling is installed on described torsion spring (8) two ends by torsion spring (8), are respectively formed, and described screw mandrel (2) axle places the flat hole of described coupling band (3); Described motor (6) main shaft places the flat hole of described coupling band (7).
