Description
Technical field
The utility model relates to a kind of brake separating mechanism, particularly a kind of brake separating mechanism with roller.
Background technology
The tripping electromagnet of common brake separating mechanism is all that movable directly shock takes off oralia, drives closing holding mechanism to rotate, after making main shaft discharge combined floodgate energy, realizes separating brake.
Problem existing for existing brake separating mechanism is: because coil trip rod is in the process of clashing into de-oralia in brake separating mechanism, the crest line of coil trip rod end contacts with de-oralia, interaction between the crest line of coil trip rod end and de-oralia is sliding friction, scratch can take off oralia; In addition, owing to there is sliding friction, coil trip rod can occur to jump and crawl in motion process, and therefore when doing the divide-shut brake characteristic of circuit breaker, opening characteristic is unstable, has had a strong impact on the serviceability of circuit breaker.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of brake separating mechanism with roller, and the frictional force between coil trip rod and dropout plate is reduced, and opening characteristic is stablized.
The purpose of this utility model is achieved through the following technical solutions:
Comprise brake separating mechanism mounting panel, switching winding, coil trip rod, dropout plate, back-moving spring and separating brake semiaxis, described switching winding is fixed on brake separating mechanism mounting panel, the space that described coil trip rod insertion switching winding surrounds also is stretched out, and axially do rectilinear motion along switching winding, described separating brake semiaxis and coil trip rod vertical interlaced are arranged, and be arranged on coil trip rod external part, described dropout plate one end is sheathed on separating brake semiaxis, and can rotate around separating brake semiaxis, the one side that the free end of described dropout plate parallels with separating brake semiaxis axis is oppositely arranged with coil trip rod free end, described dropout plate is provided with back-moving spring, the free end of described coil trip rod is provided with roller, described roller and dropout plate Structure deformation.
Further, dropout plate longitudinal section is q font.
Further again, switching winding is fixed on brake separating mechanism mounting panel by screw.
The beneficial effects of the utility model are:
Be rolling friction between the coil trip rod of this brake separating mechanism and dropout plate, frictional force is little, and opening characteristic is stablized.
Accompanying drawing explanation
In order to make the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, the utility model is described in further detail, wherein:
Fig. 1 is the brake separating mechanism front sectional view of the utility model band roller.
Embodiment
Hereinafter with reference to accompanying drawing, preferred embodiment of the present utility model is described in detail.
As shown in Figure 1, a kind of brake separating mechanism with roller, comprise brake separating mechanism mounting panel 1, switching winding 2, coil trip rod 4, dropout plate 6, back-moving spring 7 and separating brake semiaxis 8, switching winding 2 is fixed on brake separating mechanism mounting panel 1, coil trip rod 4 inserts space that switching winding 2 surrounds and stretches out, and axially do rectilinear motion along switching winding 2, separating brake semiaxis 8 and coil trip rod 4 vertical interlaced are arranged, and be arranged on coil trip rod 4 external part, dropout plate 6 one end is sheathed on separating brake semiaxis 8, and can rotate around separating brake semiaxis 8, the one side that the free end of dropout plate 6 parallels with separating brake semiaxis 8 axis is oppositely arranged with coil trip rod 4 free end, dropout plate 6 is provided with back-moving spring 7, the free end of coil trip rod 4 is provided with roller 5, roller 5 and dropout plate 6 Structure deformation.
Improve further as the utility model, dropout plate 6 longitudinal section is q font.
Further improve as the utility model, switching winding 2 is fixed on brake separating mechanism mounting panel 1 by screw 3.
When after switching winding energising, coil current can produce magnetic field, and the magnetic field of generation makes coil trip rod 4 outwards extend, thus the roller 5 on coil trip rod 4 clashes into dropout plate 6, realizes separating brake; When switching winding 2 dead electricity, magnetic field dissipate, coil trip rod 4 is retracted, and dropout plate 6 resets under the effect of back-moving spring 7; Coil trip rod 4 at the bottom of this brake separating mechanism and between dropout plate 6 for rolling friction, frictional force is little, and opening characteristic is stablized.
