Detailed Description

The technical solution of the present invention is described in detail below with reference to the accompanying drawings, but the scope of the present invention is not limited to the embodiments.

A variable-pitch slip ring brush wire fixing device is shown in figure 1 and comprises an installation frame 1, brush wire plates, brush wire plate fixing screws 3, brush wire bundles 4 and a variable-pitch slip ring stator side cable 5, wherein the brush wire plates are fixedly locked on a brush wire plate frame 1 through the four brush wire plate fixing screws 3.

A circuit loop slideway is preset on the wire brushing plate and is divided into two specifications: three slide brush silk boards 1 and four slide brush silk boards 2. As shown in fig. 2, three preset circuits 213 and a three-position connector 214 connected to all the preset circuits 213 are disposed on the three-way brush filament plate 1, and a group of brush filament bundle fixing holes 211 and a group of three-position connector fixing holes 212 are correspondingly disposed in each preset circuit 213. As shown in fig. 3, four preset circuits 223 and a four-position connector 224 connected to all the preset circuits 223 are disposed on the four-slide brush filament plate 2, and a group of brush filament bundle fixing holes 221 and a group of four-position connector fixing holes 222 are correspondingly disposed in each preset circuit 223.

The brush wire plates of this embodiment are arranged in two groups on opposite sides of the mounting frame 1, the brush wires on each side being arranged in a substantially symmetrical, but not absolutely symmetrical, arrangement. The sum of the number of the circuit loop slideways arranged on all the brush wire plates on the two sides of the mounting frame 1 is equal to half of the number of the brush wire bundles 4, and if one side of the mounting frame 1 in the embodiment has 10 slideways, two three-slideway brush wire plates 1 and one four-slideway brush wire plate 2 can be used.

As shown in fig. 4, when the three-slideway wire brushing plate 1 is used, three brush wire bundles 4 are welded in three groups of brush wire bundle fixing holes 211 on the three-slideway wire brushing plate 1 according to a set angle, and three pitch-variable slip ring stator-side cables 5 are respectively inserted into three cable fixing holes of the three-position connector 214. At the moment, current can enter the three-position connector 214, the preset circuit 213 and the brush wire bundle 4 once through the pitch slip ring stator side cable 5, so that a complete current path is formed.

As shown in fig. 5, when the four-slideway brush wire plate 1 is used, four rows of brush wire bundles 4 are welded in four groups of brush wire bundle fixing holes 211 on the four-slideway brush wire plate 1 according to a predetermined angle, and four pitch-variable slip ring stator-side cables 5 are respectively inserted into four cable fixing holes of the four-position connector 214. At the moment, current can enter the four-position connector 214, the preset circuit 213 and the brush wire bundle 4 once through the variable pitch slip ring stator side cable 5 to form a complete current path.

As mentioned above, although the present invention has been shown and described with reference to certain preferred embodiments, it should not be construed as limiting the invention itself. Various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
