Description
Technical field
The utility model relates to actuator field, relates in particular to a kind of YE.
Background technology
A kind of drive unit that straight line can be provided or rotatablely move of YE, it utilizes electric energy and works under certain control signal effect, and is used for valve to be urged to the position of standard-sized sheet or complete shut-down. Existing YE complex structure, valve opening control accuracy is poor, and in the time there is power-off, valve opening is uncontrollable, affects normally carrying out of related work.
Utility model content
The technical problem existing based on background technology, the utility model proposes a kind of YE, to solve the problems of the technologies described above.
A kind of YE the utility model proposes, comprising: housing, motor, drive bevel gear, driven wheel of differential, rotating shaft, power transmission shaft and handwheel, in housing, there is cavity, motor is arranged in described cavity, and its output shaft is horizontally disposed with, drive bevel gear is arranged on motor output shaft periphery, driven wheel of differential is positioned at drive bevel gear below, and engage with drive bevel gear, rotating shaft is arranged in driven wheel of differential, rotating shaft vertically arranges, its one end is rotationally connected by bearing and housing, the other end has external screw thread, and be fixedly connected with power transmission shaft, power transmission shaft offers the internal thread that described rotating shaft external screw thread coordinates along its length, and part is positioned at hull outside, handwheel can carry out vertical displacement and be arranged on housing, its axle core end has the circular groove coordinating with rotating shaft.
Preferably, motor is variable-frequency motor.
Preferably, power transmission shaft is socketed with buffer bar away from rotating shaft one side periphery, between buffer bar and power transmission shaft, is connected by spring.
Preferably, also comprise the control panel being arranged on outside housing, this control panel is used for controlling machine operation.
A kind of YE the utility model proposes, starter motor, motor output shaft drives drive bevel gear to rotate, drive bevel gear drives driven wheel of differential to rotate, driven wheel of differential drives rotating shaft synchronously to rotate, and because rotating shaft is connected by engage thread with power transmission shaft, power transmission shaft is vertically moved, power transmission shaft motion drives buffer bar vertically to move, to control the folding of the valve being connected with buffer bar. When power-off, press down handwheel, after handwheel is fixedly connected with rotating shaft, rotation hand wheel, rotating shaft is rotated, and buffer bar is vertically moved, with by-pass valve control aperture, valve reaches after predetermined aperture, upper handle wheel, handwheel separates with rotating shaft, when stopping to power, damages because maloperation handwheel causes motor overheating. The YE the utility model proposes, simple in structure, reasonable in design, valve opening control accuracy is high, and when power-off, still controllable valve door is to predetermined aperture.
Brief description of the drawings
Fig. 1 is the structural representation of a kind of YE that the utility model proposes.
Detailed description of the invention
As shown in Figure 1, Fig. 1 is the structural representation of a kind of YE that the utility model proposes.
With reference to Fig. 1, a kind of YE the utility model proposes, housing 1, motor 2, drive bevel gear 3, driven wheel of differential 4, rotating shaft 5, power transmission shaft 6 and handwheel 7, in housing 1, there is cavity, motor 2 is arranged in described cavity, and its output shaft is horizontally disposed with, drive bevel gear 3 is arranged on motor 2 output shaft peripheries, driven wheel of differential 4 is positioned at drive bevel gear 3 belows, and engage with drive bevel gear 3, rotating shaft 5 is arranged in driven wheel of differential 4, rotating shaft 5 vertically arranges, its one end is rotationally connected by bearing and housing 1, the other end has external screw thread, and be fixedly connected with power transmission shaft 6, power transmission shaft 6 offers the internal thread that described rotating shaft 5 external screw threads coordinate along its length, and part is positioned at housing 1 outside, handwheel 7 can carry out vertical displacement and be arranged on housing 1, its axle core end has the circular groove coordinating with rotating shaft 5.
In the time of specific design, motor 2 is variable-frequency motor.
Power transmission shaft 6 is socketed with buffer bar 8 away from rotating shaft one side periphery, between buffer bar 8 and power transmission shaft 6, is connected by spring 9, and the fluctuation of available buffer valve folding, with the control accuracy of poppet folding.
In addition, also comprise the control panel 10 being arranged on outside housing 1, this control panel 10 is worked for controlling motor 2.
In the present embodiment, when work, starter motor 2, motor 2 output shafts drive drive bevel gear 3 to rotate, and drive bevel gear 3 drives driven wheel of differential 4 to rotate, and driven wheel of differential 4 drives rotating shaft 5 synchronously to rotate, because rotating shaft 5 is connected by engage thread with power transmission shaft 6, power transmission shaft 6 is vertically moved, and power transmission shaft 6 motions drive buffer bar 8 vertically to move, to control the folding of the valve being connected with buffer bar 8.
When power-off, press down handwheel 7, after handwheel 7 is fixedly connected with rotating shaft 5, rotation hand wheel 7, rotating shaft 5 is rotated, and buffer bar 8 is vertically moved, with by-pass valve control aperture, valve reaches after predetermined aperture, upper handle wheel 7, handwheel 7 separates with rotating shaft 5, when stopping to power, crosses cause thermal damage because maloperation handwheel causes motor 2.
The YE the utility model proposes, simple in structure, reasonable in design, valve opening control accuracy is high, and when power-off, still controllable valve door is to predetermined aperture.
The above; it is only preferably detailed description of the invention of the utility model; but protection domain of the present utility model is not limited to this; any be familiar with those skilled in the art the utility model disclose technical scope in; be equal to replacement or changed according to the technical solution of the utility model and utility model design thereof, within all should being encompassed in protection domain of the present utility model.
