Abstract
The utility model discloses a transmission mechanism in an electric operating mechanism of a circuit breaker, comprising a gear wheel arranged on the speed reducing mechanism of the circular breaker, a transmission shaft, a cam arranged on the lower end of the transmission shaft, and a slide block under the cam. The cam and the slide block are in contradiction with each other, an engaging and disengaging gear arranged between the transmission shaft and the gear wheel comprises a ratchet wheel and a ratchet, and the ratchet wheel is arranged on the gear wheel or on the transmission shaft; the ratchet can be rotatablely arranged on the transmission shaft or on the gear wheel, the ratchet and the ratchet wheel are matched with each other. The ratchet and the ratchet wheel occupy smaller height in longitudinal direction; the volume of the product is decreased.
Description
Technical field
The utility model relates to the transmission device in a kind of electric operating mechanism of circuit-breaker.
Background technology
In the prior art, transmission device in the motor-operating mechanism of circuit breaker is referring to China Patent No. 00112313.0, and it adopts power transmission shaft and a pair of clutch, drives clutch by reduction gearing, drive power transmission shaft by clutch again, thereby drive cam and slide block carry out the electricity operation.But a pair of clutch is vertically separating or combination, and institute takes up space bigger, makes the volume of product increase, and causes increasing of cost of transportation.
Summary of the invention
The utility model purpose provides the transmission device in a kind of electric operating mechanism of circuit-breaker, and its vertical volume is less.
For achieving the above object, the technical solution adopted in the utility model is: the transmission device in a kind of electric operating mechanism of circuit-breaker, comprise gear, power transmission shaft on the reducing gear that is arranged on circuit breaker, be arranged on the bottom of described power transmission shaft cam, be positioned at the slide block of the downside of described cam, described cam and slide block are inconsistent, are provided with arrangement of clutch between described power transmission shaft and the gear; Described arrangement of clutch comprises ratchet and pawl, and described ratchet is arranged on one of them of described gear or power transmission shaft, and described ratchet is arranged on another of power transmission shaft or gear rotationally, and described ratchet matches with described ratchet.
Because technique scheme utilization, the utility model compared with prior art has following advantage: a pair of ratchet and pawl is set between gear and power transmission shaft, during electric operating, one of them rotation by gear driven ratchet or ratchet, make another rotation in its drive ratchet or the ratchet, to drive power transmission shaft,, drive cam and slide block operate thereby carrying out electricity; And during manual operation, the direct control power transmission shaft gets final product, and does not produce impetus between the ratchet and pawl.Because ratchet and pawl is less at vertical shared height, reduced the volume of product.
Description of drawings
Accompanying drawing 1 is a main cutaway view of the present utility model;
Accompanying drawing 2 is the A-A profile in the accompanying drawing 1;
Wherein: 1, manual operation handle; 2, shell; 3, direction board; 4, power transmission shaft; 5, upper mounting plate; 6, ratchet; 7, gear; 8, lower installation board; 9, cam; 10, slide block; 11, circuit breaker; 12, ratchet; 13, ratchet rotation axis; 14, back-moving spring;
Embodiment
Referring to accompanying drawing 1-accompanying drawing 2, transmission device in a kind of electric operating mechanism of circuit-breaker, comprise gear 7, power transmission shaft 4 on the reducing gear that is arranged on circuit breaker, be arranged on the bottom of described power transmission shaft 4 cam 9, be positioned at the slide block 10 of the downside of described cam 9, described cam 9 is inconsistent with slide block 10.Be provided with arrangement of clutch between described power transmission shaft 4 and the gear 7, described arrangement of clutch comprises ratchet 12 and ratchet 6, described ratchet 12 is arranged on one of them of described gear 7 or power transmission shaft 4, described ratchet 6 is arranged on another of power transmission shaft 4 or gear 7 rotationally, and described ratchet 6 matches with described ratchet 12.In the embodiment shown in Figure 2, be set with ratchet 12 on the described power transmission shaft 4, described gear 7 head lamp brush guard pivots are connected with ratchet 6, and described ratchet 6 is positioned at the outside of ratchet 12.For strengthening the impetus of 6 pairs of ratchets 12 of ratchet, be provided with two ratchets 6 on the described gear 7 at least, and between described ratchet 6 and described gear 7, be connected with back-moving spring 14.
Referring to accompanying drawing 1, also be provided with manual operation handle 1 in the upper end of power transmission shaft 4.When the gear 7 of reducing gear moves in the direction of the clock to the position shown in the accompanying drawing 2, be attached thereto the ratchet 6 that connects also thereupon move in the direction of the clock (position of ratchet 6 and direction transformation are easy to regulate by back-moving spring 14 in this process), therefore ratchet 12 is just promoted by ratchet 6, thereby can drive the rotation of power transmission shaft 4, carry out the electricity operation to drive cam 9 and slide block 10.With dump, the impetus of 6 pairs of ratchets 12 of ratchet disappears, rotate manual operation handle 1 in the direction of the clock, can directly drive power transmission shaft 4 and do clockwise rotatablely moving, at this moment, the 12 no thrust drags of 6 pairs of ratchets of ratchet, then the rotation of ratchet 12 reducing gear of gear 7 and connection gear 7 is not exerted an influence, thereby can drive cam 9 like a cork and slide block 10 carries out the electricity operation.And,,, thereby dwindled the volume of product so both are shorter in the length that vertically distributes because ratchet 12 and ratchet 6 laterally roughly are being in the same plane.
