Description
Technical field:
The present invention is a kind of carbon brush configuration that is used for having on the generator excitation slip ring color scale limitation locking.
Background technology:
There is following technical problem in the carbon brush configuration of using on the generation current machine, and constant force spring is fixing and mounting means is very inconvenient, and dismountable although the constant force spring that has adopts, its processing technology is very complicated.Also very undesirable to fixing of carbon brush when the carbon brush configuration dismounting, the employing mechanical compaction that has is fixed, and end-stopping plate is fixed before the fragile carbon brush, the employing machinery that has, with regard to more fragile carbon brush.Main is the device that the related product of these technical schemes is not all observed the carbon brush abrasion condition, brings inconvenience to the user.
Summary of the invention:
Purpose of the present invention aims to provide a kind of carbon brush wear condition of being convenient to observe, the spacing convenient and reliable carbon brush that do not damage again of carbon brush during dismounting, and the fixing simple technical scheme of constant force spring is to overcome weak point of the prior art.
The technique effect that the present invention will reach is to adopt following technical scheme to realize, a kind of carbon brush configuration that has color scale limitation locking, it has the spill stage body seat that is fixed on the conducting ring, on the rotation axis in the rectangular channel of convex stage body seat holddown spring is housed, and on convex stage body seat, be fixed with supporting plate, it is characterized in that: in guide pin bushing, constant force spring and following constant force spring are equipped with in following two sides, be fixed with catch two spring leaf upper ends, with two hold-down screws 3 two spring leaf lower ends are fixed in the rectangular recess, an end is fixed in the catch hole behind the steel wire penetrating cable-through hole, the other end be fixed on the rotation axis the axle fixing hole in, be fixed with positive stop strip in the supporting plate back, wear-resisting arc plate rear end at carbon brush is fixed with the spacing steelframe of elasticity, on the spacing steelframe of elasticity, bar is housed, on guide pin bushing, be fixed with the colour code chi, scribble red on the colour code chi from left to right, yellow, green three looks; Guide pin bushing quantity can 1,2 or a plurality of.
The technique effect that technical scheme provided by the present invention reached is such, when carbon brush is installed, the rotation rotation axis makes on the steel wire rope and moves, catch lifts under two spring leaf effects, carbon brush pushes from the guide pin bushing left end, the elastic force that overcomes upper and lower constant force spring is stuck on the catch the spacing steelframe of elasticity, reaches that carbon brush can not eject in the carbon brush process is installed.Back rotation rotation axis is installed is driven steel wire rope catch is displaced downwardly in the rectangular recess, remove catch spacing to the spacing steelframe of elasticity, promptly carbon brush contacts slip ring and starts working under the effect of upper and lower constant force spring.Bar on the spacing steelframe of elasticity and carbon brush one starting simultaneously, indication carbon brush state of wear, whether the user of announcement needs to change carbon brush.When needing to change after carbon brush work a period of time, the spacing steelframe of elasticity rear end is near the outside of positive stop strip, so carbon brush moves to left under the elastic force effect when dismounting, but limited outside, the spacing steelframe of elasticity rear end blocked and can not be moved, take off brush lead after pulling down and lift the spacing steelframe carbon brush of elasticity and just can replace with new carbon brush again from the taking-up of guide pin bushing left side.During installation convex stage body seat is put into spill stage body seat, and will lock post aligning locking post via hole and pass, rotary handle makes the locking post be stuck on the spill platform header board catch of leaving behind simultaneously.Convex stage body seat is contacted well with spill stage body base inner surface.
Technical scheme involved in the present invention compared with prior art has outstanding progress and significant technique effect, so novel structure of the present invention, ingenious, simple, very easy to use, the good reliability of production of design, the technical scheme of being convenient to observe is provided, has had novelty, creativeness and practicality.
