Abstract
The utility model discloses a transmission structure which comprises a support, a hand-operated rod and a worm and gear self-lock device, wherein the hand-operated rod and the worm and gear self-lock device are respectively arranged on the support. The hand-operated rod is connected with a gear A which is meshed with a gear B, the gear B is connected with the worm and gear self-lock device which is connected with an output shaft, and the axis of the output shaft is perpendicular to the axis of the hand-operated rod, so that rotating of the output shaft is achieved. The transmission structure of an operating mechanism for a generator circuit breaker earth switch is small in size, convenient to operate and high in cost performance and has high use value.
Description
Technical field
The utility model relates to a kind of generator outlet circuit interrupter grounding switch with the drive mechanism of operation mechanism, belongs to High-Voltage Electrical Appliances and field of mechanical technique.
Background technique
At present, domestic have a kind of double worm and gear transmission device, but seem that size is larger when this device is used for the earthed switch operation, and cost is high, hand inconvenience.Therefore, research and develop the drive mechanism that a kind of structural volume is little, cost is low, hand easily generator outlet circuit interrupter grounding switch is used operation mechanism, become the technical problem that related domain needs to be resolved hurrily at present.
The model utility content
The purpose of this utility model provides the drive mechanism that a kind of generator outlet circuit interrupter grounding switch is used operation mechanism, and this drive mechanism volume is little, easy to operate, and cost performance is high, is applicable to the earthed switch operation of generator outlet circuit breaker.
The purpose of this utility model realizes by following technical proposals.
A kind of drive mechanism, comprise support, and be separately positioned on hand operating stem and worm and gear self-locking device on the support, described hand operating stem is connected with gear A, gear A engaging gear B, described gear B links to each other with the worm and gear self-locking device, and the worm and gear self-locking device connects output shaft, the output shaft axle center is mutually vertical with described hand operating stem axle center, thereby realizes the output shaft rotation.
The utility model is further characterized in that:
Described worm and gear self-locking device comprises the worm screw that links to each other with gear B, described worm meshing worm gear.
Described worm gear one side has supporting sleeve.
Be provided with damping device on the described output shaft.
The beneficial effects of the utility model are, compare with double worm and gear to have the following advantages: adopt the first-stage worm gear worm drive, part still less, size is little, cost is low; Hand direction of operating is mutually vertical with the output shaft axis, when hand, can be in the side of mechanism, and easy to operate; Hand driving gear adopts the pair of straight gear, makes simply, and cost is low.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the side view of Fig. 1.
Among the figure: 1, support; 2, hand operating stem; 3, worm screw; 4, output shaft; 5, damping device; 6, supporting sleeve; 7, worm gear; 8, gear A; 9, gear B.
Embodiment
Below in conjunction with accompanying drawing the utility model is done and to be described in further detail:
As shown in Figure 1 and Figure 2, this drive mechanism, comprise support 1, and being separately positioned on hand operating stem 2 and worm and gear self-locking device on the support 1, hand operating stem 2 is connected with gear A 8, gear A 8 engaging gear B9, gear B 9 links to each other with the worm and gear self-locking device, the worm and gear self-locking device that is installed on the support 1 is installed in output shaft 4 on its worm gear 7, and output shaft 4 axle center are mutually vertical with described hand operating stem 2 axle center, thereby realizes output shaft 4 rotations.
The worm and gear self-locking device comprises the worm screw 3 that links to each other with gear B 9, and worm screw 3 engagement worm gears 7 have self-lock ability.
And among the embodiment, worm gear 7 one sides have supporting sleeve 6, are provided with damping device 5 on the output shaft 4.
The gear B 9 of this structure is loaded on the worm screw 3 and with gear A 8 and meshes, and forms the one-level gear transmission.Gear B 9 is loaded on the hand operating stem 2, and hand operating stem 2 supports by support two projections, and hand operating stem 2 one ends are taken part in rocking handle.
Wind is inserted hand operating stem 2 rotations, and by the one-level gear transmission, the first-stage worm gear worm drive realizes the output shaft rotation.
During hand operation, hand this structural volume is little, easy to operate, and cost performance is high, has higher use value.This structural volume is little, and is easy to operate, and cost performance is high, has higher use value.The conical surface end that inserts hand operating stem 2, to rotate by rotation joystick driven gear A8 and gear B 9, gear B 9 drives worm screw 3 and worm gear 7 rotates, and worm gear 7 drives output shaft 4 rotations, outputs power.
This structure can be carried out electric operating by translator.During electric operating, motor output shaft is connected by certain mode with worm shaft end, when electrical power rotates, drives worm and worm gear and rotate, thereby drive the output shaft rotation, electric power is exported.During electric operating, output shaft end has a damping device 5, can prevent from impacting.
The above is described this structure by reference to the accompanying drawings; but this structure is not limited to above-mentioned concrete mode; above-mentioned embodiment only is schematic; rather than circumscribed; those skilled in the art is under the enlightenment of this structure; under the scope that the aim that does not break away from this structure and claim are protected, can also make a lot of forms, these all belong within the protection of the present utility model.
