The utility model is characterized in that the electric speed reduction device is suspended below the inner top wall of the guard shell, and the bottom end of the side wall on the periphery of the guard shell is fixedly connected to the upper side of the flange disk; the guard shell not only has the function of guard, but also is used as a suspending supporting frame of the electric speed reduction device and the lower end of the guard shell is directly arranged above the flange disk and is fixedly connected. The utility model has the advantages of convenient assembly and maintenance, structure simplification, high reliability, accurate gear position, more changing gear positions, small installation opening hole of a transformer, balanced stress, no leakage of round sealing, etc. The insufficiencies of the shape and structures of like products in the past are overcome.
Description
Technical field
The utility model relates to a kind of power transmission and transformation improved circular motor drive mechanism once more, is the power control unit that the sub-connecting switch of transformer gear is adjusted.
Background technology
Existing power transmission and transformation tapping switch electric mostly is square configuration, and as depicted in figs. 1 and 2, it comprises that transition gear pays 1, and ring flange 2, main shaft 3, protective cover 4, sheave 5, slot poking ware 6, travelling gear are paid 7, the two cover worm and gears structure 8 and 9 that slows down.The deficiency or the shortcoming of square motor drive mechanism are as follows: 1, complex structure, reliability decrease: the parts sum is above 300.2, transformer installation perforate is big, and unbalance stress: mounting flange is square, and installing hole also is square, has four angles, has stress to concentrate.3, quad seal is not as circular seal: quad seal circle side ratio is during to the circular seal ring equal diameters, and the big sealing property of its girth is relatively poor.4, the gear precision is low: transition gear is paid 1 gap and is caused dynamic and static contact gear deviation.5, the conversion gear is few: sheave 5 diameters are very little, and its circumference gear half arc is limited, and general square motor drive mechanism has only 13 grades at most.6, transmission link is many, the volume heaviness, and material and cost of transportation increase.
Summary of the invention
The purpose of this utility model provides a kind of power transmission and transformation with the improved once more circular motor drive mechanism of shunting switch, and (simplified structure improves reliability to have overcome the deficiency of above square motor drive mechanism, reasonable in design, improve serviceability, lose weight, reduce cost).
The purpose of this utility model is to adopt the technical scheme of following renewal to realize: it mainly comprises ring flange, central principal axis, bowl-shape sheave, guard shield, the gear control panel, the slot poking ware of electronic deceleration device and its power spindle nose that is connected is characterized in that electronic deceleration device is lifted on below the guard shield inner roof wall, and guard shield circumferential side wall bottom connects firmly and is seated above the ring flange.
Above-mentioned guard shield also can be designed to cage hoisting bracket structure, and electronic deceleration device lifts on it, at the outside of hoisting bracket assembling outer cover.
The power spindle nose of electronic deceleration device of locus is being connected and is having the slot poking ware of beam type shift fork in the above-mentioned bowl that is in bowl-shape sheave.
Above-mentioned ring flange is configured to circular or square.
The bowl-type circumferential side wall of above-mentioned bowl-shape sheave can be a spherical calotte, also can be part bucket wall, and the staggered some gears spaced apart of its upper port locate recessed half arc and gear is dialled the commentaries on classics open slot.
The utility model has the advantages that: guard shield had not only been had a protective action but also be the hoisting bracket of electronic deceleration device, and its lower end directly is seated in above the ring flange and connects firmly.Assembling and maintenance are all very convenient, because when removing guard shield, electronic deceleration device is also taken simultaneously, and two internal structures of bowl-type sheave and gear control panel have just been confronted entirely; And when the shift fork of slot poking ware further adopts the beam type structure, removed an outer arm of slot poking ware both arms, the bowl-type sheave diameter has further been increased, as far as possible near guard shield, this has just increased it and has rotated the arm of force, reduce power, increased moment of torsion, reduced the gear error, increased gear quantity, gear is accurate, and the conversion gear is many, can reach more than 30 grades; Structure is simplified, and reliability improves; It is little that transformer is installed perforate, stress equalization; Circular seal is non-leakage.Overcome the deficiency of like product shape and structure in the past.

Embodiment
The utility model specific embodiment is seen Fig. 3-5, and its structure comprises: ring flange 2, central principal axis 10, bowl-shape sheave 11, electronic deceleration device 12, guard shield 13, slot poking ware 6, gear are seen and are looked into window 14, gear control panel 15 etc., structure is greatly simplified, and critical piece has only 99 of 7 part sums.Concrete structure is as follows: sealing and fixing seals on the ring flange 2 of transformer-cabinet and installs central principal axis 10.Central principal axis 10 upper ends connect firmly bowl-shape sheave 11, and the bowl-type circle wall of bowl-shape sheave 11 can be a spherical calotte, also can be part bucket walls, and the staggered gear spaced apart of its upper port locatees recessed half arc 11-2 and gear is dialled commentaries on classics open slot 11-1.The electronic deceleration device 12 of existing structure occupies space in the bowl-shape sheave 11, and the power spindle nose 12-1 of electronic deceleration device 12 is being connected and is having the slot poking ware 6 of beam type shift fork 6-1, and the protruding half arc 6-2 in location is set on the slot poking ware 6.At the outer cup of said apparatus dress guard shield 13, and electronic deceleration device 12 is lifted on below guard shield 13 inner roof walls by connector, and guard shield 13 circumferential side wall bottoms connect firmly and are seated in above the ring flange 2.Guard shield 13 also can be designed to cage hoisting bracket structure, and electronic deceleration device 12 lifts on it, at the outside of hoisting bracket assembling outer cover 13-1 (the double dot dash line part among Fig. 3).The structure of ring flange 2 can be circular or square.
Its operating process is as follows: when needs are adjusted the output voltage of transformer; the operator presses the relevant gear key of controller at operating desk; the electronic deceleration device 12 that is lifted on guard shield 13 top cover lower planes gets; its power spindle nose 12-1 drives slot poking ware 6 and does constant angular velocity ω 1 rotation; see Fig. 4 and Fig. 5; when the gear of cutting bowl-shape sheave 11 as the shift fork 6-1 of slot poking ware 6 is dialled and is changeed open slot 11-1; just stir bowl-shape sheave 11 and drive central principal axis 10 with variable angular velocity ω 2 rotations; and the moving contact that is passed to the shunting switch body that is lifted on ring flange 2 lower ends switches gear; during the position location of the recessed half arc 11-2 in location that cuts bowl-shape sheave 11 as the protruding half arc 6-2 in the location of slot poking ware 6; being positioned at bowl-shape sheave 11 following gear control panels 15 cuts off the power supply; and make electronic deceleration device 12 dead electricity; and shut down; the moving contact of shunting switch body just stops at deciding on the contact contact conducting gear of required switching this moment, looks into window 14 and just as seen knows the place gear and see by gear.Simultaneously on far-end operation platform controller, corresponding demonstration is also arranged, just finished the gear adjustment process one time.
