Abstract
An one-way transmission decelerator in circuit-breaker electric actuation mechanism comprises an independent closing casing and a drive main shaft rotating relative to the casing, wherein, the casing is provided inside with a worm wheel, a worm, a pinion and a bull gear; the worm wheel and the worm are joggled each other; the pinion and the worm wheel are disposed fixedly and coaxially into an integrity; the bull gear is fixed on the drive main shaft; the pinion is joggled with the bull gear; between the bull gear and the drive main shaft a one-way bearing is arranged and able to prevent the drive main shaft from driving the bull gear when the drive main shaft is directly rotated, thereby the decelerator is labor-saving during manual operation.
Description
Technical field
The utility model relates to a kind of transmission decelerating device, relates in particular to a kind of unidirectional transmission decelerating device that aims at electric operating mechanism of circuit-breaker and design.
Background technology
Speed reduction gearing among the present domestic electricity behaviour all is two-way speed reduction gearing basically, when manually directly rotating transmission main shaft, transmission main shaft can drive the rotation of gear wheel, owing to will drive gear wheel and rotate, will spend bigger strength like this during so direct rotation transmission main shaft.
Summary of the invention
The purpose of this utility model is a kind of unidirectional transmission decelerating device that provides in the electric operating mechanism of circuit-breaker, and it can make that transmission main shaft can not drive gear wheel and rotate when directly rotating transmission main shaft.
The utility model is implemented by the following technical programs:
Unidirectional transmission decelerating device in a kind of electric operating mechanism of circuit-breaker, it comprises independent closure and the transmission main shaft that can rotate with respect to described shell, be provided with worm gear, worm screw, pinion, gear wheel in the described shell, described worm gear and worm engaging, described pinion and the coaxial regularly setting of described worm gear one, described gear wheel is fixed on the described transmission main shaft, described pinion is meshed with described gear wheel, between described gear wheel and the described transmission main shaft unilateral bearing is housed.
The utility model and prior art are existing than following advantage is arranged: the unidirectional transmission decelerating device in the described electric operating mechanism of circuit-breaker is by making when being rotated in a clockwise direction transmission main shaft with hand at installation unilateral bearing between transmission main shaft and the gear wheel, transmission main shaft does not drive gear wheel and rotates, like this when this deceleration device of manual operation as long as just can be so that transmission main shaft rotation with smaller strength, thereby reached the labour-saving effect.
Description of drawings
Accompanying drawing 1 is the enclosure structural representation of unidirectional transmission decelerating device of the present utility model;
Accompanying drawing 2 is the motor of unidirectional transmission decelerating device of the present utility model and the connection layout of shell;
Wherein: 1, worm screw; 2, worm gear; 3, pinion; 4, gear wheel; 5, transmission main shaft; 6, shell; 7, unilateral bearing; 8, motor; 9, groove.
Embodiment
Unidirectional transmission decelerating device in a kind of electric operating mechanism of circuit-breaker as shown in Figure 1, it comprises independent closure 6 and the transmission main shaft 5 that can rotate with respect to described shell 6, be provided with worm gear 2 in the described shell 6, worm screw 1, pinion 3, gear wheel 4, described worm gear 2 and worm screw 1 engagement, described pinion 3 and the coaxial regularly setting of described worm gear 2 one, described gear wheel 4 is fixed on the described transmission main shaft 5, described pinion 3 is meshed with described gear wheel 4, between described gear wheel 4 and the described transmission main shaft 5 unilateral bearing 7 is housed.
Described worm screw 1 is by the drive of motor 8.
As shown in Figure 2, described motor 8 is positioned at the outside of described shell 6.
The other end of described transmission main shaft 5 connects the eccentric cam of electric operating mechanism of circuit-breaker.
When electric operating: after motor 8 is being received signal, drive worm screw 1 motion, described worm screw 1 drives worm gear 2 motions, described worm gear 2 is because coaxial with described pinion, rotate so also just drive pinion 3, it is moving that described pinion 3 drives gear wheel 4 dresses, and described gear wheel 4 drives transmission main shaft 5 and rotates, transmission main shaft 5 drives the eccentric cam among the electricity behaviour again, thereby makes the electronic operate as normal of electricity behaviour.
When manual operation: stir operating grip, thereby the eccentric cam running of the electric operating mechanism of circuit-breaker that the other end that makes transmission main shaft 5 rotate drive and described transmission main shaft 5 connects, owing between described transmission main shaft 5 and the gear wheel 4 unilateral bearing 7 is housed, when main shaft rotates, will can not drive gear wheel 4 like this and rotate, thereby make the manual operate as normal of electricity behaviour.
In each functional unit, mix tangible electricity behaviour sign board, make more convenient operation quick.
