Detailed description of the invention
As shown in Figure 1-2, angle stroke gearbox structure described in this utility model embodiment, including casing 1, worm gear 2, worm screw 3, spur gear I 4, spur gear II 5, the internally installed worm gear 2 of described casing 1 and case lid 9 is set at worm gear 2 place exterior thereto, this case lid 9 outward flange is connected by hex bolts 7 is fixing with casing 1, the described internally installed worm gear set of worm gear 2, fixed installation actuating sleeve 8 in the centre bore of this worm gear set, between actuating sleeve 8 therein and case lid 9, and it is respectively mounted bearing on worm gear 2, actuating sleeve 8 therein arranges direction board 14 with case lid 9 junction, described casing 1 arranges mechanical position limitation bolt 22 with worm gear 2 junction；
Correspondingly, described casing 1 outer edge installs a worm screw 3 in offering a cylindrical cavity and this cavity, the outer surface of this worm screw 3 engages each other with the tooth of tooth and this tooth with worm gear 2, wherein one end of this worm screw 3 is cased with lining 11 and installs end cap 10 at this end, this end cap 10 is fixed on casing 1 by some hex bolts 7, and worm screw 3 therein is installed roller bearing 6；
Correspondingly, described worm screw 3 other end arranges bearing block, this bearing block is outside installs casing, spur gear I 4 is fixedly mounted between described casing and bearing block, ball bearing is installed between this spur gear I 4 and bearing block, spur gear I 4 external tooth therein engages each other with the external tooth of spur gear II 5, installs and arrange flat key 16 on axle 15 and this axle 15 in the centre bore of described spur gear II 5, and this axle 15 outer surface installs two ball bearings；Meanwhile, described axle 15 outer end arranges jump ring 13, at the outside mounting flange 17 of casing and arrange therebetween O 12.
Angle stroke gearbox structure described in above this utility model embodiment, electric operator transfers torque to the axle of reduction box, the rotating speed of executor is reduced by the double reduction gear of shaft portion by the engaged transmission of a pair big small Spur gear, and the rotating speed after reducing with this is delivered to worm screw, and drives worm screw to rotate；Worm screw support angle orientation, has complete self-locking performance, it is simple to the total travel location of butterfly valve flap；After worm screw rotates, further being reduced by rotating speed by the worm gear engaged, whole reduction box is to be reduced by the rotating speed of electric operator by slowing down of firsts and seconds, and by moment amplification, controls the valve of high-torque.
There are two mechanical position limitation bolts in the both sides of Gearbox, control the spacing of worm gear wheel stroke, determine being accurately positioned of butterfly valve flap with this；It is connected by parallel key between worm gear with worm gear set, the rotation of worm gear drives worm gear set to start to rotate, and the endoporus of worm gear set is internal spline structure, just engages with the actuating sleeve of external splines structure and the moment of torsion that the reliable and stable transmission of spline structure is huge can be passed through；Actuating sleeve uses spline connected mode, and moveable actuating sleeve is readily accessible, actuating sleeve internal openings, and it is that the valve rod with valve carries out nested encryptions and transmits moment of torsion；Actuating sleeve drives the switch total travel that the valve rod of butterfly valve carries out 90 °, reaches the angle location of control valve family of power and influence's lobe with this thus reaches to control the instruction of pipeline flow.The self-locking property of worm screw protects the location of valve rod, it is therefore prevented that impacts flap because pipeline flow is unstable and has caused peak torque, thus the abrasion of the worm and gear tooth caused or bending, damage internal core parts；Additionally, built-in oils and fats improves the mechanical service life of reduction box, Gearbox is provided with oil filler point, it is simple to daily maintenance；Being furnished with direction board on reduction box case lid, direction board is valve flap positioner, it is possible to the keying percentage ratio that instruction valve is current.
