Description

Technical Field

[0001] The utility model relates to the field of carbon brushes, in particular to a stable generator carbon brush capable of reducing carbon brush sparks. Background Art

[0002] Carbon brushes, also known as electric brushes, are sliding contact parts that are widely used in many electrical devices. The main material used in carbon brushes is graphite. Carbon brushes are devices that transfer energy or signals between the fixed and rotating parts of a generator. They are generally made of pure carbon and a coagulant. They are generally square in shape and are stuck on a metal bracket. A spring inside presses them tightly against the shaft. Long-term use during operation causes continuous wear on the surface of the carbon brush, which can lead to uneven contact with the shaft. The weakening of the spring's elasticity over time can also cause the carbon brush to misalign with the shaft. Uneven contact can easily generate sparks, which not only wears out the carbon brushes and slip rings but also affects the stable operation of the generator. Utility Model Content
