Also for example can be equipped with on the said worm gear output shaft 16: the device Q that photoelectric encoder or other can the feedback cloud stand rotary angle signals is used for feedback cloud stand and rotates to the angle that another point is rotated by a bit, and this angle signal is passed to the cradle head control circuit.
Need to prove: be made as one-level deceleration or multi-stage speed-reducing (being that secondary or secondary are above slows down) between said deceleration driving gear and the driven reduction gearing.
Principle of work of the present invention is: this The Cloud Terrace can be according to the action of operating personnel's instruction control axial motor; Axial motor can spur or promote dial; Utilize dial and driven reduction gearing, driven constant speed gear different combinations, change the The Cloud Terrace gear drive and recently change the The Cloud Terrace rotational speed.When needs are sought the observation distant object for example certain beyond 10 kilometers a bit, 1 C between A, the B among Figure 10 for example.Operating personnel can send instruction to The Cloud Terrace, by cradle head control drives axial motor, make axial motor drive shift fork and promote left; Make dial on worm screw, slide left, this moment, motor was in operating condition, and driven reduction gearing dallies on worm screw under deceleration driving gear drives; When the hole on pivot pin on the dial and the driven reduction gearing coincides; Pivot pin inserts in the hole on the driven reduction gearing, and this moment, deceleration driving gear drove driven reduction gearing, and driven reduction gearing drives dial; Dial drives worm screw, and worm screw drive worm gear is followed The Cloud Terrace by worm gear output shaft drive high power pick-up lens at last and rotated together.Because the decelerating effect of driven reduction gearing The Cloud Terrace this moment with an extremely low speed, begins rotation such as 0.001 ° of per second and seeks target being observed.Meanwhile driven constant speed gear dallies as shown in Figure 3 under the drive of constant speed driving gear on worm screw.
Need to rotate to the E point from the A point shown in figure 10 when The Cloud Terrace, because the The Cloud Terrace anglec of rotation is bigger, this moment, The Cloud Terrace needed 80 ° of a higher speed speed ratio such as p.s.s.This moment, the The Cloud Terrace operating personnel can send instruction to The Cloud Terrace, by cradle head control drives axial motor, made axial motor drive shift fork and spurred to the right; Make dial on worm screw, slide to the right, this moment, motor was in operating condition, and driven constant speed gear dallies on worm screw under the constant speed driving gear drives; When the hole on pivot pin on the dial and the driven constant speed gear coincides; Pivot pin inserts in the hole on the driven constant speed gear, and this moment, the constant speed driving gear drove driven constant speed gear, driven constant speed gear driven dial; Dial drives worm screw, and worm screw drive worm gear is followed The Cloud Terrace by worm gear output shaft drive high power pick-up lens at last and rotated together.Because the ratio of gear of constant speed driving gear and driven constant speed gear is less than the ratio of gear of deceleration driving gear and driven reduction gearing, this moment, the The Cloud Terrace rotating speed was higher such as rotating 80 ° p.s..Meanwhile driven reduction gearing dallies as shown in Figure 4 under the drive of deceleration driving gear on worm screw.
The last of The Cloud Terrace grade deceleration is the worm gear reducer that has auto-lock function; So work as dial under the drive of axial motor; Pivot pin in the dial breaks away from driven reduction gearing and when not combining with driven constant speed gear; Perhaps pivot pin breaks away from driven constant speed gear and when not combining with driven reduction gearing, and is as shown in Figure 1, the high power pick-up lens that the worm gear output shaft is driven be can be because of the reason of gravity voluntarily around the rotation of worm gear output shaft.Luckily dial pivot pin in the middle of horizontally slipping not necessarily just can insert in the middle of the hole of driven reduction gearing, driven constant speed gear in addition; But driven reduction gearing, driven constant speed gear are rotating under the drive of motor, and dial is in the middle of the drive lower shaft pin of axial motor is just fallen the hole of driven reduction gearing, driven constant speed gear naturally after gear rotates to an angle.
For the The Cloud Terrace that the presetting bit requirement is arranged; In switching the speed gear process; Be installed in the device that photoelectric encoder or other on the worm gear output shaft can the feedback cloud stand rotary angle signal, can the anglec of rotation of The Cloud Terrace be fed back to the cradle head control circuit, guarantee the cradle head preset positions precision.
In a word, The Application of Technology of the present invention can satisfy the batch process needs of various products fully, and will give play to its huge economic and social benefit.
