Abstract
The utility model provides an operating mechanism of the motor, which is technically characterized in that the motor is connected with a change speed gear which is connected with a lead screw; the lead screw is arranged on the spindle; a nut is positioned on the lead screw; a segment gear is arranged on the superior end of the spindle; an output gear is positioned on the output shaft; the output gear is meshed with the segment gear; one end of the lead screw is connected with the change speed gear, and a spring is positioned at the other end of the lead screw; the inferior end of the spindle is connected with an auxiliary switch which is connected with a quick-acting switch device; a fork-lever is positioned on the spindle. The utility model has the advantages of accurate discharge end, reliable location, and lock function, the automatic release of the superfluous ration energy of the motor at the end point of the opening and closing switches, which alleviates the terminal impact, and the middle-positioned output shaft increases the rotary-angle of the output shaft.
Description
Technical field:
The utility model relates to a kind of motor operating mechanism, particularly a kind of novel motor operating mechanism.
Technical background:
Present China motor operating mechanism, there are " turbine-worm screw " formula and " shift fork-screw rod " formula two classes in its mechanically operated core, the latter has and much is better than the former part on performance, show that mainly the final position is accurate and have lock function and terminal point can alleviate bump (motor excess energy when terminal point exhausts automatically), but the shortcoming that the latter exists is the output angle of mechanism has only 90 °, thereby can not provide the isolating switch of big operation corner (being generally 180 °) to use.
Summary of the invention:
The purpose of this utility model is at the deficiency in the above-mentioned technology, a kind of novel motor operating mechanism is provided, this operating mechanism final position is accurate, the location is reliable, lock function is arranged, the unnecessary rotational energy of separating brake combined floodgate ultimate position motor can be eliminated automatically, thereby alleviate the bump of terminal point, and the position of output shaft is placed in the middle, has enlarged the corner of output shaft.
The purpose of this utility model is to realize like this, comprise motor, gear, leading screw, screw, shift fork, axle, quick switching device, it is characterized in that, motor is connected with change-speed gearing, change-speed gearing is connected with leading screw, and leading screw is installed on main shaft, and screw is housed on leading screw, the upper end of main shaft is equipped with sector gear, output gear is installed on the output shaft, and output gear is meshed with sector gear, and an end of leading screw is connected with change-speed gearing, the other end is equipped with spring, lower end at main shaft is connected with auxiliary switch, and auxiliary switch links to each other with quick switching device, and shift fork is installed on main shaft.
The utility model has the advantages that the final position is accurate, the location is reliable, lock function is arranged, and the unnecessary rotational energy of separating brake, combined floodgate ultimate position motor can be eliminated automatically, thereby alleviates the bump of terminal point, and the position of output shaft is placed in the middle, has enlarged the corner of output shaft.
Description of drawings:
Fig. 1 is a structural representation of the present utility model
Embodiment:
Below in conjunction with accompanying drawing present embodiment is described further:
As shown in Figure 1, motor 1 is connected with change-speed gearing 2, change-speed gearing 2 is connected with leading screw 3, leading screw 3 is installed on main shaft 6, screw 4 is housed on leading screw 3, the upper end of main shaft 6 is equipped with a sector gear 7, output gear 8 is installed on the output shaft 9, output gear 8 is meshed with sector gear 7, and an end of leading screw 3 is connected with change-speed gearing 2, and the other end is equipped with spring 13, be connected with auxiliary switch 12 in the lower end of main shaft 6, auxiliary switch 12 links to each other with 11 with quick switching device 10, and shift fork 5 is installed on main shaft 6, and spring 12 is fixed on the two ends of leading screw 3.Its operation principle is that motor 1 drives change-speed gearing 2 and rotates, 3 rotations of change-speed gearing 2 drive leading screws, screw 4 on the leading screw 3 is defined on a vertical plane, therefore left (combined floodgate direction) or to the right (separating brake direction) move, promote shift fork 5 thus and rotate, shift fork 5 is an integral body with axle 6, so axle 6 rotates, sector rack 7 is being fixed in axle 6 upper ends, and sector rack 7 is stirred output gear 8 and rotated, and output gear 8 is as a whole with output shaft 9, so output shaft 9 rotates, satisfy 180 degree corners.
The lower end of screw 4 is a straight-bar, when moving near branch, combined floodgate final position, stirs quick switching device 10 or 11 and makes auxiliary switch 12 change its contact deciliter states, for sending electric position signalling.
