Background technology
The spring operating mechanism of traditional vacuum circuit breaker comprises: transmission main shaft, is fixed by socket the first cam, gear positioning sleeve, gear and the second cam on described transmission main shaft successively; Described the first cam, gear positioning sleeve and the second cam carry out axial location by two positioning sleeves that are fixed on described transmission main shaft; The face of keeping out on described gear positioning sleeve coordinates the described gear to being set on described gear positioning sleeve to carry out axial location with described the second cam.Applicant finds in practical operation, because the positioning precision of positioning sleeve is poor, adopts after positioning sleeve axial location, each parts that are axially located still can move axially, locating effect is poor, and the flat key of circumferential positioning action that easily worn and torn, thereby affects the serviceability of product.
Utility model content
To this, technical problem to be solved in the utility model is that the spring operating mechanism of traditional vacuum circuit breaker exists axial location weak effect, causes the affected problem of serviceability of product.
The technical scheme that realizes the utility model object is:
A spring operating mechanism for vacuum circuit-breaker, comprises transmission main shaft, and is sleeved on successively the first cam, gear positioning sleeve, gear, the second cam and back-up ring on described transmission main shaft; On described transmission main shaft, one end of close described the first cam forms and stops boss, one end near described back-up ring on described transmission main shaft forms threaded portion, described threaded portion threaded has setscrew nut, described in stop that boss coordinates with described setscrew nut described in being located at and stop that described the first cam between boss and described setscrew nut, described gear positioning sleeve, described the second cam and described back-up ring carry out axial location; The face of keeping out on described gear positioning sleeve coordinates the described gear to being set on described gear positioning sleeve to carry out axial location with described the second cam.
In technique scheme, the boss that stops taking shape on described transmission main shaft is annular boss.
In technique scheme, described transmission main shaft is ladder cylindrical structural.
In technique scheme, described the first cam, described gear positioning sleeve, described the second cam and described back-up ring are circumferentially located by flat key.
In technique scheme, described gear positioning sleeve is copper positioning sleeve.
The utlity model has positive effect:
In the utility model, by stop boss and the setscrew nut being screwed onto on transmission main shaft taking shape on transmission main shaft, each parts that are positioned at are between the two carried out to axial location, after having located, each parts that are axially located can not move axially, good positioning effect, and can avoid the flat key of its circumferential positioning action to be worn, thereby effectively guaranteed the serviceability of product; And adopt structure of the present utility model when assembling, one end that the first cam, gear positioning sleeve, the second cam and back-up ring are arranged to threaded portion from transmission main shaft is sleeved on transmission main shaft, and by described gear set on gear positioning sleeve, then screw setscrew nut and can complete assembling, assembling speed significantly promotes, and effectively improves the efficiency of assembling of product.
