Description
Technical field
It the utility model is related to breaker apparatus field, and in particular to a kind of small-sized reclosing drive mechanism.
Background technology
Reclosing drive mechanism is a kind of automatics for automatically engaging the breaker after barrier tripping for some reason on demand.Mesh
Preceding reclosing device on the market is mainly that the output gear engaged by driving gear drives rotates, so drive with it is defeated
The take-off lever for going out gear-linked rotates, and completes the combined floodgate of breaker.Chinese patent literature（The day for announcing：It is on April 19th, 2017, public
The number of opening：CN106571272A）Disclose a kind of automatic reclosing drive mechanism, including transmission worm gear, output gear, output master
Axle, dropout STATEMENT OF FEDERALLY SPONSORED and the circuit board with central control circuit；Transmission worm gear is provided with cam linkage portion, worm gear follower, tooth
Wheel drive portion and thumb wheel portion；The periphery wall in thumb wheel portion is provided with and stirs boss；On the part wall body of the periphery wall of gear drive division
Provided with multiple sliding tooths；The portion perimeter wall of output gear is provided with and multiple output gears of gear drive division adaptation.Its
Middle sliding tooth and output gear are not the structures of whole engagement, and gear is when being engaged, and it contacts the position of engagement at first
It is fixed to put, and said structure cannot be guaranteed that sliding tooth and the position that output gear contacts at first are to be touched needed for normal engagement
Position, this is resulted in actual use, sliding tooth and output gear engage and have some setbacks or even stuck feelings occur
Condition, influence the normal operation of drive mechanism.Further, since close a floodgate when need to overcome certain pretightning force, now, sliding tooth and
The active force being subject on output gear at the intermeshing gear teeth is very big, and by much time using, the gear teeth herein may go out
The situation of existing damaged even fracture, influences the normal operation of drive mechanism.
The content of the invention
In view of the deficiency of background technology, it is simpler that technical problem to be solved in the utility model is to provide a kind of structure
It is single, firm so that it, which closes a floodgate, more stablizes, and effectively improves the small-sized reclosing drive mechanism of its service life.
Therefore, the utility model is realized using following scheme：
Small-sized reclosing drive mechanism, including drive device, drive gear, output shaft and fan-shaped output gear, the drive
Dynamic device is connected with drive gear, the output shaft respectively with fan-shaped output gear and the divide-shut brake handle of external breaker
Linkage, the side of drive gear one is integrally provided with the fan-shaped sliding tooth coordinated with fan-shaped output gear, when the fan-shaped drive
After moving teeth drives fan-shaped output gear to go to combined floodgate angle, the fan-shaped sliding tooth separates with fan-shaped output gear, and its feature exists
In：The fan-shaped output gear is lengthening tooth, the fan-shaped output gear and sector with the gear teeth that fan-shaped sliding tooth engages at first
The gear teeth that sliding tooth finally engages is thicken tooth, and the corresponding thickening tooth, the gear teeth of fan-shaped sliding tooth are also thickening tooth.
Preferably, the drive gear side is integrally provided with dropout projection.
Preferably, the drive device includes motor and the worm screw with motor drive connection, the snail
Worm and wheel is engaged, and the first travelling gear, the first travelling gear of institute and the second transmission are coaxially provided with the side of worm gear one
Gear engages, and the side of the second travelling gear one is coaxially provided with the 3rd travelling gear, the 3rd travelling gear and driving
Gear engages.
Preferably, the worm gear and the first travelling gear are integral type structure, second travelling gear and the 3rd passes
Moving gear is integral type structure.
It is using above-mentioned technical proposal, the advantages of the utility model：1st, as a result of fan-shaped output gear, and driving
The side of gear one drives output gear rotation integrally provided with the fan-shaped sliding tooth coordinated with fan-shaped output gear in fan-shaped sliding tooth
To combined floodgate angle, fan-shaped output gear separates with fan-shaped sliding tooth, no matter now whether motor stops at once, output gear is
It is no also to rotate, all without fan-shaped output gear is influenceed, the accuracy of combined floodgate is ensure that, and prevent because motor does not stop at once
Inter deterioration caused by and, and when breaker occur overload or it is short-circuit situations such as need separating brake to disconnect when, due to now fan-shaped defeated
Go out gear not engaging with fan-shaped sliding tooth, therefore fan-shaped output gear can directly turn round carry out separating brake, it is not necessary to drive
Motor reversal drives drive gear reversion to coordinate so that the simpler convenience of separating brake process；2nd, due to fan-shaped output gear with
The gear teeth that fan-shaped sliding tooth engages at first is lengthen tooth, so in making process, fan-shaped sliding tooth can be first with lengthening toe joint
Touch, and stir fan-shaped output gear and go to optimal tooth matching angle, it is ensured that fan-shaped output gear is suitable with both fan-shaped sliding tooths
Profit engagement, avoid fan-shaped output gear and stuck situation occur with fan-shaped sliding tooth, effectively improve the stability of mechanism；3rd, by
Be thickening tooth in the gear teeth of fan-shaped output gear and fan-shaped sliding tooth in last engagement place, i.e., pointedly strengthen the two by
The intensity of power maximum tooth, so as to effectively increase the stability and service life of reclosing action.4th, by drive gear
Side is integrally provided dropout projection, and as the drive gear rotates, the dropout projection is first driven on external breaker
Release lever action is completed to thread off, and fan-shaped sliding tooth described afterwards engages with fan-shaped output gear, drives fan-shaped output gear to rotate
Closed a floodgate, and then effectively instead of the tripping mechanism set on conventional drive mechanism so that its structure is simpler, Er Qie
It can just complete to thread off in drive gear rotation process, improve the fluency of combined floodgate.
