Abstract
The utility model relates to a reduction box for a spring operating mechanism for a high-voltage circuit breaker. The gear box comprises a motor; a reduction gear consisting of two levels of gear clusters, worm wheels and worms; and a clutch gear consisting of an energy storage turn arm, a pull-out piece spring, a pin, a lee spring, and a pin bolt. The output gear of the motor drives the worm via the two levels of gear clusters, the worm wheel meshing the worm and the energy storage turn arm are coaxially encased on the cam shaft of the spring operating mechanism, the end surface of the worm wheel is provided with a chute, one end of the pin can be inserted into the chute, and slide into and out of the chute against the turn of the energy storage turn arm. The pin bolt is provided with a spring and arranged at the lower part of the reduction box shell. When the energy storage turn arm reaches a fixed position, the lee spring on the pin bolt will drive the bolt to break away from the worm wheel. The utility model has the advantages of a simple structure, low manufacturing cost and high reliability of operation.
Description
Affiliated technical field
The utility model belongs to high voltage electric equipment device technology field, relates to a kind of high-voltage breaker spring operating mechanism reduction box.
Background technology
Present high-voltage breaker spring operating mechanism well known in the art is mainly the structure that adopts level Four gear drive or the transmission of two-stage worm and gear with reduction box, in actual applications, though the reduction box transmission efficiency of level Four gear transmission structure is higher, but making in mechanism also need increase deceleration device and slow down, make that mechanism exists that inner components is many, complex structure, the high deficiency of manufacturing cost, though the reduction box inner components of two-stage worm and gear transmission is less, but its volume is big, and transmission efficiency is also lower.
The utility model content
The purpose of this utility model is to solve the problem that prior art exists, so provide a kind of modern design, simple in structure, volume is little, low cost of manufacture, stable performance, high-voltage breaker spring operating mechanism reduction box that transmission efficiency is high.
Be used to realize that the technical solution of foregoing invention purpose is such: the high-voltage breaker spring operating mechanism that is provided has motor with reduction box, tank shell, be located at tank shell by two-stage gear train and worm gear, the deceleration device that worm screw is formed and by the energy storage connecting lever, stage clip, pin, torsion spring, the arrangement of clutch that pin is formed, the output gear shaft of motor is connected with worm-drive by the two-stage gear train, with the worm gear of worm engaging and energy storage connecting lever coaxial package on the camshaft of spring operating mechanism, on the worm gear end face, have skewed slot, one end of pin can insert in the skewed slot and can be under the stage clip effect skid off along with the rotation of energy storage connecting lever slides into along skewed slot, connect the bottom that the pin that torsion spring is housed is located at tank shell on it, after the energy storage connecting lever forwarded some fixed positions to, the torsion spring on the pin can be stirred pin and make it to break away from worm gear.In the practical operation, power passes to arrangement of clutch by deceleration device, drives camshaft and energy-stored spring work in the breaker spring operating mechanism.
Compared with prior art, the utlity model has clear, low cost of manufacture simple in structure, stable performance, reliability advantages of higher, after installing in mechanism, tank shell just is closed, and is convenient to lubricate, noise is low, transmission efficiency is high.In addition, the modular project organization of this reduction box also is convenient to final assembly, and demonstrates in-house no longer messy complexity, and whole structure is good.
Description of drawings
Fig. 1 is the structural representation of a specific embodiment of the utility model.
Fig. 2 is the A-A cross-sectional view of Fig. 1.
Embodiment
Referring to accompanying drawing, this high-voltage breaker spring operating mechanism comprises parts such as motor 1, tank shell 2, deceleration device and arrangement of clutch with reduction box.Deceleration device is by worm gear 7, worm screw 6 and a pair ofly form with 3,4 and gears 5 that are contained on the worm screw 6 of shaft transmission gear, gear 3 in the in-line gears meshes with the gear output shaft of motor 1, another gear 4 and gear on worm 5 engagements, constitute the two-stage driving gear set, worm screw 6 is meshed with worm gear 7, worm gear 7 is sleeved on the camshaft 9 of spring operating mechanism, has skewed slot on worm gear 7 end faces.Arrangement of clutch is made up of energy storage connecting lever 8, stage clip 10, pin 11, pin 13 and the torsion spring 12 that is contained on the pin 13, energy storage connecting lever 8 is sleeved on the camshaft 9 of spring operating mechanism, one end of pin 11 can insert in the skewed slot and can be under stage clip 10 effects skid off along with the rotation of energy storage connecting lever 8 slides into along skewed slot, pin 13 is located at the bottom of tank shell 2, after energy storage connecting lever 8 forwards some fixed positions to, the other end of pin 11 can be stirred by the torsion spring on the pin 13 12, and pin 11 breaks away from worm gear 7.During the product assembling motor 1 directly is fixed on the tank shell 2, other parts are installed in the tank shell 2.
The working forms of this reduction box comprises two kinds of electric operating and manual operations.During electric operating, after the energising of motor 1 output shaft is rotated,, drive worm screw 6 and worm gear 7 and rotate in succession, promote energy storage connecting lever 8 by the pin in the arrangement of clutch 11 and rotate together, rotate thereby drive camshaft 9 through the transmission of two-stage gear train; Energy storage connecting lever 8 forwards a fixed position to, and the torsion spring 12 on the pin 13 is transferred to pin 11 and made it to break away from worm gear 7, and worm gear 7 no longer drives energy storage connecting lever 8 and rotates; Camshaft 9 rotates, drive energy storage connecting lever 8 and turn over certain angle, pin 11 slips over from torsion spring 12, under stage clip 10 effects, rotation along with energy storage connecting lever 8, pin 11 slides at the skewed slot of worm gear 7 end faces and skids off, and have only worm gear 7 can drive energy storage connecting lever 8 this moment and rotates together, and energy storage connecting lever 8 can not drive worm gear 7 rotations.During manual operation, finish the above-mentioned course of work with handle rotary worm 6.
