The rotary driving force of output shaft be by gear train with the power output transmission of stepping motor to the actuating force that obtains on the output shaft.
In order to form small-sized valve with electrically motorized operation, stepping motor and the gear box that is arranged on the motor bottom are arranged in the housing, this gear box is built-in with gear train.
For existing this motor assembling body, scale error because of component parts, when assembling, can produce error, make that the actual disposition of stepping motor is fixing insufficient, need be to this operation of fixedly adjusting, therefore have the situation of destroying assembleability and take place, perhaps when applying multi-load, cause the breakage of gear box, thereby become the reason that reduces its reliability.
Summary of the invention
Therefore, purpose of the present invention just provides a kind of motor assembling body that addresses the above problem and uses this motor to assemble the valve with electrically motorized operation of body.
To achieve these goals, motor of the present invention assembling body by below forms the housing of peristome, stepping motor that top in this housing is provided with, the bottom that is arranged on this stepping motor in the substrate establishing the gear box of the gear train that this stepping motor drives and be used for fixing the bearing of using by the output shaft of said gear group driving form, and form the rubber layer of one in this substrate bottom surface, the above-mentioned rubber layer of peristome riveted and fixed at above-mentioned housing, it is characterized in that, between above-mentioned motor and above-mentioned housing, elastomer is set flexibly.
Adopt motor assembling body of the present invention, owing between motor and housing, have elastomer, when absorbing scale error, the pressure that can obtain to be scheduled to, thus it is good to become assembleability, the motor assembling body that reliability is high.
In addition, motor assembling body of the present invention, because as the elastomer use is metal pad or the pad with the portion of having dashed, so can utilize elasticity fixed motor, gear box etc. under predetermined load of pad, the error that produces when absorbing assembling, and obtain the high motor assembling body of reliability.
In addition, valve with electrically motorized operation provided by the invention, it is characterized in that having above-mentioned motor assembling body of the present invention, by output shaft with the valve rod of axial direction operation, the valve body that the valve body of valve chamber arranged and be installed in valve stem tip and engage and separate with the throttle orifice of valve chamber.
Adopt this valve with electrically motorized operation, owing to be valve body to be engaged and separation by the valve rod that above-mentioned motor assembling body drives, so obtained the high valve with electrically motorized operation of reliability.
Description of drawings
Fig. 1 is the profile as the valve with electrically motorized operation that motor assembling body is installed of one embodiment of the invention;
Fig. 2 is mounted in the elastomeric schematic diagram of the upper bottom portion of housing;
Fig. 3 is an elastomeric side view shown in Figure 2.
Embodiment
Fig. 1 is the schematic diagram of an embodiment of motor assembling body of the present invention and the valve with electrically motorized operation that uses this motor assembling body.
Valve with electrically motorized operation body 10 has valve chamber 12, and the pipe 20,22 for cold-producing medium outflow and inflow usefulness that is communicated with this valve chamber 12 is installed.
Valve body 30 is installed in the top of valve rod 40, and output shaft 60 moves up and down valve body 30 via ball 42 with the cardinal extremity butt of valve rod 40.By moving up and down of valve rod 40, valve body 30 engages with throttle orifice 14 or separates, thus the area of control stream.
Output shaft 60 has external screw thread 61, internal thread 71 threaded engagement of this external screw thread 61 and bearing part 70.Bearing part 70 is fixed on the valve body 10 by cap nut 74.
Outer circumference portion at valve rod 40 is equipped with bellows 50, thus the cold-producing medium of seal valve chamber 12 sides.
And, be provided with circular flat substrate 150 on the top of bearing part 70, this substrate 150 relatively will have the housing cylindraceous 160 at the end to hide, and rivet processing by the riveted joint forming section 162 that the lower opening portion at housing 160 forms, and make substrate 150 and housing cylindraceous 160 fixing.At this moment, substrate 150 is fixed by riveting at the rubber layer 152 of its integrated formation in bottom surface and by cramping.
In housing 160 inside, contain the assembly of stepping motor 100 and gear box 120.Stepping motor 100 has coil 112 and rotor 114.
The output shaft of rotor 114 is arranged in the gear chamber 122 of gear box 120 inside.The pinion of drive gear set 130 (with regard to Fig. 1, because of omitting at its rear that is positioned at figure), the power output of being slowed down by gear train are delivered to the gear 132 of terminal section.
Gear 132 rotations drive output shaft 60, and the rotation of output shaft 60 is transformed into rectilinear motion and is delivered to valve rod 40 by screw thread 61,71.
As shown in Figure 1, between the upper bottom portion 161 and stepping motor 100 of the housing 160 that contains stepping motor 100, be provided with space 180.At the flexible body of these space 180 interpolations.And, with regard to Fig. 1, be provided with metallic plate 163 on the top of stepping motor 100, thereby form space 180.Perhaps, between plate 163 and elastomer insulated enclosure being set also is fine.
