Description

Technical Field

[0001] The utility model relates to the field of carbon brushes, in particular to a carbon brush holder which is convenient for fixing 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 carbon brushes requires a carbon brush holder, and the function of the carbon brush holder is to apply pressure to the carbon brushes that are in sliding contact with the commutator or slip ring surface through a spring, so that it can stably conduct current between the fixed body and the rotating body. For the motor, the brush holder and carbon brushes are both very important components, so the installation of carbon brushes requires a carbon brush holder that is easy to fix the carbon brushes.

[0004] However, most of the carbon brush holders currently used for fixing carbon brushes have poor fixing effect on the carbon brushes, which leads to the carbon brushes being easily loosened during use. Therefore, a lot of time is required for maintenance, thereby reducing work efficiency. Therefore, it is necessary to improve it.

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