Technical Field

[0001] The utility model relates to the field of carbon brushes, in particular to a fixing device for carbon brushes. Background Art

[0002] Carbon brushes, also known as electric brushes, are sliding contacts that are widely used in many electrical devices. The main materials used in carbon brushes are graphite, impregnated graphite, metal containing copper, and silver graphite. Carbon brushes are devices that transfer energy or signals between the fixed part and the rotating part of an electric motor, generator, or other rotating machinery. They are generally made of pure carbon and a coagulant. They are generally square in shape and are stuck on a metal bracket. There is a spring inside that presses it tightly against the shaft. When the motor rotates, the electrical energy is transmitted to the coil through the commutator. Since its main component is carbon, it is called a carbon brush. It is easy to wear and should be regularly maintained and replaced, and carbon deposits should be cleaned.

[0003] The installation of the carbon brush requires fixing it, so a fixing device for the carbon brush is required.

Since the fixing devices are fixedly installed on the motor housing and are not easy to disassemble, replacement or daily inspection, fault repair, and cleaning of internal carbon residue are extremely inconvenient, which affects the normal operation of the motor and reduces the working efficiency of the motor. Therefore, there is a need to improve them.

[0005] Therefore, in order to solve the above problems, a fixing device for carbon brushes is proposed. Utility Model Content
