Abstract
The utility model provides an electric brush assembly including an annular installation piece and an electric brush shell piece installed on the installation piece fixedly and symmetrically. The electric brush shell piece is provided with a through electric brush cavity axially. A carbon brush is disposed in the electric brush cavity. The head of the carbon brush is in a shape of a sunken arc face. The tail of the carbon brush is provided with an anti-releasing groove. The carbon brush connects with a power source electrically. Spring hooks are also arranged on the left end and the right end of the brush shell piece. A tension spring is arranged between the spring hooks. Tension spring grooves are arranged in a left wall and a right wall of the electric brush cavity. A middle section of the tension spring goes through the tension spring grooves in the electric brush cavity and entraps into the anti-releasing groove in the carbon brush to extrude the carbon brush inwardly. The electric brush assembly in the utility model has a beneficial effect of novel structure. And the carbon brush can be replaced and installed conveniently.
Description
Technical field
The utility model relates to a kind of brush assembly.
Background technology
Brush is to do sliding contact and form a kind of conductive component that is electrically connected with movement parts.Brush is applicable on commutator or the slip ring, as the sliding contact body that imports and exports electric current.Its conduction, heat conduction and greasy property are good, and have certain mechanical strength.Nearly all direct current machine and commutating machine all use brush, and it is the important composition parts of motor; Good in order to conduct electricity, electromechanics trade we select carbon brush as brush.We often are assembled into these parts of brush assembly to carbon brush and associate member thereof, to be installed on the motor.But the brush assembly on the existing motor must be dismantled the carbon brush that whole assembly could be changed wearing and tearing when maintenance, and it is easy for installation that we provide a carbon brush replacing here, the brush assembly that structure is novel.
Summary of the invention
Change the deficiency of inconvenience in order to overcome existing carbon brush, the utility model provides a kind of structure novel, and carbon brush is changed brush assembly easy for installation.
The technical scheme that the utility model solves its technical problem is: a kind of brush assembly; Comprise that an annular installation sheet and symmetry are installed in the brush shell sheet on the installation sheet; Radially be provided with a penetrating brush chamber on the described brush shell sheet, said brush is provided with carbon brush in the chamber, and said carbon brush nose shape is a recessed cambered surface; Afterbody is provided with an anticreep groove, and said carbon brush is electrically connected with power supply; End also is provided with spring carrier arm about said brush shell sheet, is linked with an extension spring between said spring carrier arm, and the left and right sides, said brush chamber wall is provided with the extension spring groove, and said extension spring middle-end is passed the anticreep groove that the extension spring groove on the brush chamber is absorbed on the carbon brush and inwardly pushed carbon brush.
Further, the mode that said carbon brush is electrically connected is that the carbon brush afterbody is provided with a hole, fixing and electric connection of power supply line one end in said hole, and the power line other end is connected with power supply.Carbon brush directly is connected with power supply makes its power supply performance good, and power consumption is little.
The utility model is installed in motor rear end with brush assembly in use and covers, and carbon brush places in the brush chamber, and the extension spring two ends are hung on two spring carrier arms, and middle-end is elongated and penetrated the extension spring groove, is absorbed in the anticreep groove of carbon brush, and carbon brush just can tightly prop up commutator.
When repairing, draw back extension spring, hanging up extension spring after carbon brush is more changed can accomplish.
The beneficial effect of the utility model is: structure is novel, and carbon brush is changed easy for installation.
Description of drawings
Fig. 1 is the schematic appearance of an embodiment of the utility model.
Fig. 2 is the assembling sketch map of an embodiment of the utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further explain.
In conjunction with attaching Fig. 1 and 2, a kind of brush assembly comprises that an annular installation sheet 1 is installed in the brush shell sheet 2 on the installation sheet with symmetry; Radially be provided with a penetrating brush chamber 3 on the described brush shell sheet 2, be provided with carbon brush 4 in the said brush chamber 3, said carbon brush 4 nose shapes are a recessed cambered surface; Afterbody is provided with an anticreep groove 5; Afterbody also is provided with a hole, fixing and electric connection of power supply line 9 one ends in said hole, and power line 9 other ends are connected with power supply; Carbon brush 4 directly is connected with power supply makes the brush power supply performance good, and power consumption reduces; Said brush shell sheet about 2 ends also are provided with spring carrier arm 6; 6 of said two spring carrier arms are linked with an extension spring 7; The left and right sides, said brush chamber wall is provided with extension spring groove 8; The extension spring groove 8 that said extension spring 7 middle-ends are passed on the brush chamber is absorbed in the anticreep groove 5 inside extruding carbon brush 4 on the carbon brush, makes its head lake surface firmly prop up commutator.
Generally we adopt two brush shell sheets 2 usually, and the carbon brush 4 of the inside is two electrodes of corresponding power respectively.
The fixed form of installation sheet and brush shell sheet can adopt riveted joint or screw element to fix.
Present embodiment is installed in motor rear end with brush assembly when mounted and covers; Carbon brush 4 places in the brush chamber 3, and extension spring 7 two ends are hung on two spring carrier arms 6, and middle-end is elongated and is inserted in extension spring groove 8; Be absorbed in the anticreep groove 5 of carbon brush, carbon brush 4 just can tightly prop up commutator.
When repairing, draw back extension spring 7, it is just passable to hang up extension spring 7 after carbon brush 4 is more changed.
Through the power supply of brush, commutator, armature just can be realized the function of conversion magnetic pole, realizes the rotation of rotor.
