Abstract
The invention belongs to the technical field of breakers and relates to a clutch, in particular to a clutch of an electric operation mechanism for a breaker. The clutch comprises a driving gear shaft, a clutch rod, a clutch shaft sleeve, a spring and a driven gear shaft. A first clutch hole and a second clutch hole are formed in the clutch shaft sleeve, wherein the first clutch hole and the second clutch hole are vertically communicated. A driving gear shaft clutch shaft is arranged at the lower end of the driving gear shaft and penetrates through the first clutch hole to enter the second clutch hole. A driven gear shaft clutch shaft is arranged on the upper portion of the driven gear shaft and enters the second clutch hole. The spring is arranged between the clutch shaft sleeve and the driven gear shaft. The clutch is easy to assemble and small in size; when the clutch is switched off, disengagement and engagement of a driving piece and a driven piece can be achieved; when the clutch is switched on, rotating of the driven piece can be achieved. The clutch is good in product uniformity, thereby being suitable for bulk production. The clutch is smooth in disengagement and engagement, free of impact, thorough in disengagement and accurate and reliable in motion.
Description
Technical field
The present invention relates to a kind of arrangement of clutch, the arrangement of clutch of motor-operating mechanism for a kind of circuit breaker, belongs to breaker technical field specifically.
Background technology
Circuit breaker motor-operating mechanism is at a distance circuit breaker being carried out a kind of electric accessories of separating brake, combined floodgate.Circuit breaker replaces manual breaking-closing operating with motor-operating mechanism, make circuit-breaker switching on-off switch more reliably, more laborsaving, safer.At present, circuit breaker with motor-operating mechanism with arrangement of clutch generally comparatively complicated and part there is the problems such as functional lability, and for fear of cause the problems such as part injury, mechanism's lost of life when the manual-operating mechanism because operating physical force is excessive, the arrangement of clutch that increases operating mechanism is again optimal selection, thereby how to design arrangement of clutch simple in structure, function-stable and just become the emphasis that designer need to consider.
Summary of the invention
The object of the invention is to overcome above-mentioned weak point, thereby the arrangement of clutch of a kind of circuit breaker with motor-operating mechanism is provided, when disconnecting, can realize the clutch of driving link and driven member; When clutch is closed, can realize driving link and drive driven member rotation, there is the features such as simple in structure, easy to assembly, flexible operation, be applicable to batch production.
According to technical scheme provided by the invention, a kind of circuit breaker comprises driving gear shaft, trip(ping) lever, clutch axle sleeve, spring and driven gear shaft with the arrangement of clutch of motor-operating mechanism, it is characterized in that: in clutch axle sleeve, be provided with the first clutch hole and the second clutch hole that are communicated with up and down, driving gear shaft lower end is provided with driving gear shaft clutch shaft, and driving gear shaft clutch shaft enters the second clutch hole through the first clutch hole.Driven gear shaft top is provided with driven gear shaft clutch shaft, and driven gear shaft clutch shaft enters the second clutch hole.Between clutch axle sleeve and driven gear shaft, be provided with spring.
Further, the first clutch hole is circular port.
Further, the second clutch hole is long waist shaped hole, and driving gear shaft clutch shaft is the long waist shaped axle identical with the second clutch hole, and driven gear shaft clutch shaft is the long waist shaped axle identical with the second clutch hole.
Further, at clutch shaft, put the fixing trip(ping) lever that can promote up and down clutch axle sleeve.
Compared with the prior art the present invention has the following advantages:
The present invention is simple in structure, compact, reasonable, and easily, one time assembly qualified rate is high in assembling; Small volume, meets the demand of market miniaturization; When clutch disconnects, the clutch of driving link and driven member can be realized, when clutch is closed, driven member rotation can be realized; Good product consistency, is applicable to batch production; Clutch is steadily without impacting, and thoroughly separated, action accurately and reliably.

Embodiment
The present invention is below further described in connection with the embodiment in accompanying drawing:
As shown in Fig. 1 ~ 7, the present invention mainly comprises driving gear shaft 1, trip(ping) lever 2, clutch axle sleeve 3, spring 4 and driven gear shaft 5, in clutch axle sleeve 3, being provided with the first clutch hole 8 and 9, the first clutch holes 8, the second clutch hole that are communicated with is up and down circular port, and the second clutch hole 9 is long waist shaped hole.
On clutch axle sleeve 3, the fixing trip(ping) lever 2 that can promote up and down clutch axle sleeve 3, is provided with spring 4 between clutch axle sleeve 3 and driven gear shaft 5.
Operation principle of the present invention is: when work, driving gear shaft clutch shaft 6 is positioned at the second clutch hole 9, and driving gear shaft 1 rotates and drives clutch axle sleeve 3 to rotate, and clutch axle sleeve 3 drives again driven gear shaft 5 to rotate.When needs are removed synchronous rotation, by trip(ping) lever 2 promotion clutch axle sleeves 3, overcome spring force and press down.Driving gear shaft clutch shaft 6 leaves the second clutch hole 9 and enters the first circular clutch hole 8, and driving gear shaft clutch shaft 6 just forms idle running after entering the first clutch hole 8, cannot drive clutch axle sleeve 3 to rotate, and clutch axle sleeve 3 also cannot drive driven gear shaft 5 to rotate.
The present invention is simple in structure, compact, reasonable, and easily, one time assembly qualified rate is high in assembling; Small volume, meets the demand of market miniaturization; When clutch disconnects, the clutch of driving link and driven member can be realized, when clutch is closed, driven member rotation can be realized; Good product consistency, is applicable to batch production; Clutch is steadily without impacting, and thoroughly separated, action accurately and reliably.
