Abstract
The utility model discloses a pressure-adjustable small-sized turbonator carbon brush pressing device, which comprises a carbon brush frame. The carbon brush frame comprises a carbon brush support and a brush holder connected with the carbon brush support, the brush holder is provided with carbon brushes, the carbon brush support is fixedly provided with a support via bolts, a U-shaped positioning groove is welded on the support, one end of the U-shaped positioning groove is provided with a hole, and a full flight screw is mounted on the hole. When the carbon brushes are in poor contact with a slide ring of a rotor, the carbon brushes can be pressed by means of manually adjusting a spring of the pressing device so that conduction current of the carbon brushes is balanced.
Description
Technical field
The utility model relates to the small-sized turbo generator carbon brush of a kind of adjustable-pressure hold down gag.
Background technology
The mode that is fixed and clamped of present small-sized turbo generator carbon brush compresses for the coiled springs chip, leans on the elastic force that curls naturally of spring leaf that carbon brush is pressed on the generator rotor ring, and pressure is unadjustable.After more renewing carbon brush or when carbon brush and generator rotor ring loose contact, the electric current difference of each carbon brush carrying of generator is very big.With my QF-12-2 of company generator is example, and the generator amature rated current is 224A, and every side has four carbon brush; The carbon brush electric current of loose contact only has tens amperes under the actual measurement rated condition, contact good carbon brush electric current and then surpasses 100 amperes, emits Mars during the big carbon brush operation of conducting electric current, in the time of seriously in addition the carbon brush body burnt red.After manually compressing the carbon brush of loose contact, the electric current of each carbon brush tends to balance, but unclamps the back problem still.Traditional spring leaf compresses mode because pressure can't be regulated, so can't address this problem.
The utility model content
The purpose of this utility model is to provide the small-sized turbo generator carbon brush of a kind of adjustable-pressure hold down gag, the utility model can be when carbon brush and rotor ring loose contact, pressure by this device spring of manual adjustments compresses carbon brush, makes the conducting current balance type of each carbon brush.
In order to achieve the above object, the technical solution of the utility model is:
The small-sized turbo generator carbon brush of a kind of adjustable-pressure hold down gag comprises carbon brush holder, and carbon brush holder comprises the carbon brush support, and the brush carrier with linking to each other with the carbon brush support is equipped with carbon brush on the brush carrier, and bolt is equipped with support on the carbon brush support; Be welded with U type location notch on the support, and offer porosely on the one end, full flight screw is installed on the hole.
Be installed with first nut on the described full flight screw, be movably installed with second nut on the full flight screw.
Welding is fixed with steady pin on described second nut, and in the U type groove that is equipped with at guide groove of steady pin.
On the full flight screw of described second nut below spring is installed, and the lower end of spring holds out against fixedly and is installed on the carbon brush.
The beneficial effects of the utility model are: the utility model can be when carbon brush and rotor ring loose contact, and the pressure by this device spring of manual adjustments compresses carbon brush, makes the conducting current balance type of each carbon brush.Have simple to operate, easy for installation, advantage of low manufacturing cost.

Embodiment
Embodiment 1
As shown in Figure 1, 2, the small-sized turbo generator carbon brush of a kind of adjustable-pressure hold down gag of present embodiment comprises carbon brush holder 9, carbon brush holder 9 comprises carbon brush support 12, brush carrier 11 with linking to each other with carbon brush support 12 is equipped with carbon brush 8 on the brush carrier 11, bolt is equipped with support 1 on the carbon brush support 12; Be welded with U type location notch 6 on the support 1, and offer porosely 10 on the one end, full flight screw 2 is installed on the hole 10.Be installed with first nut 3 on the described full flight screw 2, nut 3 is fixed on the full flight screw 2 and can not rotates, and plays adjusting screw(rod) length, prevents that simultaneously full flight screw 2 from withdrawing from from the hole 10 of support 1.Be movably installed with second nut 4 on the full flight screw 2.On the full flight screw 2 of described second nut 4 belows spring 5 is installed, and the lower end of spring 5 holds out against fixedly and is installed on the carbon brush 8.When screw thread moved, spring was loosened or is compressed at second nut 4, played the effect of regulating pressure.
Welding is fixed with steady pin 7 on described second nut 4, and steady pin 7 is equipped with in the U of guide groove 6 type groove.When rotary screw 2, nut 4 can move along the screw thread of full flight screw 2.Adopt location notch 6 and steady pin 7 to be combined with two effects:
(1) directly rotates full flight screw 2 with spanner second nut 4 is moved automatically along full flight screw 2, play compressing or the effect of pull-off spring 5, be convenient to operation.
(2) both cooperate the effect that second nut 4 is had retaining, and the carbon brush 8 of the generator that is in operation is that vibration is arranged always, gets loose for preventing second nut 4, and carbon brush 8 loses the pressure of spring 5, and this function is even more important.
