Abstract
The utility model relates to an electric brush used for a voltage regulator and an electrical motor. The utility model is compounded by a graphite block and a copper graphite block, wherein, the graphite block is sintered or pressed by graphite powder, and the copper graphite block is sintered by the graphite powder and the copper powder after mixing. The electric brush has good abrasive resistance, small sparking, low temperature rise and good electrical contact performance. The running quality and the service life of the voltage regulator and the electrical motor can be raised.
Description
The utility model relates to a kind of graphite---and the brush of copper graphite composite material belongs to the current-collector technical field.
Brush is the important process part in voltage regulator and the motor.At present, normally used brush is traditional electrographite brush or copper graphite brush in voltage regulator and motor.These brushes exist in use that the operation spark is big, temperature rise, shortcoming such as wear no resistance, and for example power is 3 kilowatts voltage regulator brush, and temperature rise can be up to 100 ℃-130 ℃ in the use, and motor brush operation spark is more than secondary.Now use the above-mentioned shortcoming of brush, have a strong impact on the running quality and the useful life of voltage regulator and motor.
The purpose of this utility model is to overcome existing above-mentioned shortcoming with brush, thereby has proposed the brush that the multiplexing material of a kind of usefulness is made.
The brush that the utility model provides is realized by following technical measures, with the graphite powder sintering or be pressed into graphite block, becomes the copper graphite block with copper with the graphite powder mixed sintering, again with graphite block and the compound brush of making of copper graphite block.
The utility model brush describes embodiment in conjunction with the accompanying drawings, and its structure can change with the different requirements of motor according to voltage regulator.Accompanying drawing 1-accompanying drawing 4 is to be made with copper graphite block 2 is compound separately by graphite block 1.Accompanying drawing 5 is to embed copper graphite block 2 to make in graphite block 1.
The designability of the utility model brush is good, and the petard performance of going out is greatly improved than existing brush, and the brush temperature rise also greatly reduces, and the resistance to wear of brush improves, and has improved the electrical contact performance of brush, the work quality and the useful life of having improved voltage regulator and motor.
Claims (1)
1, a kind of brush that is used for voltage regulator and motor, feature of the present utility model are by graphite block 1 and copper graphite block 2 is compound separately makes.
