The carbon brush holder is introduced
Published£º 2014-04-03 Be read Views£º 909
 

The function of carbon brush holder is through the spring pressure on contact with the commutator or collector ring surface sliding on the carbon brush of the steady conduction current between the fixed body and the body of revolution. For motor brush frame and carbon brush are very important parts. No matter how good the characteristics of the carbon brush, brush holder is improper, carbon brush not only can not give full play to its excellent properties, and will bring the performance and life of the motor itself.

The structure of the brush holder is to keep the carbon brush in the brush box section of the specified position, with appropriate pressure pressure carbon brush in order to prevent the pressurized part of the carbon brush vibration, brush connection box and pressurized part of the frame part and the brush frame fixed on the fixed to the motor parts. On the performance of the brush holder has the following requirements: to maintain stability of the carbon brush, inspect or replace carbon brush, easy to brush in container loading and unloading of carbon brush, can adjust the exposed part of the carbon brush under the brush box, brush box bottom edge and commutator or clearance) on the surface of the collector ring to prevent wear and commutator or collector ring and carbon brush pressure changes of direction, pressure and pressure effect on the carbon brush wear smaller, and the structure is firm. Carbon brush holder mainly adopts bronze casting, aluminum casting and other synthetic materials. Required materi

 

The performance requirements of carbon brush holder
Keep stable carbon brush, inspect or replace carbon brush, easy to brush in container loading and unloading of carbon brush, can adjust the exposed part of the carbon brush under the brush box, brush box bottom edge and commutator or clearance) on the surface of the collector ring to prevent wear and commutator or collector ring and carbon brush pressure changes of direction, pressure and pressure effect on the carbon brush wear smaller, and the structure is firm. Carbon brush holder mainly adopts bronze casting, aluminum casting and other synthetic materials. Request the brush holder itself material has good mechanical strength, processing performance, corrosion resistance, thermal properties and electric conductivity, etc.
