Abstract

The invention belongs to the technical field of massage chair motors, and particularly relates to a composite carbon brush for a massage chair motor. The composite carbon brush comprises an upper low-resistance high-conductivity layer and a lower high-resistance ultrahigh-lubrication layer, and further comprises a carbon brush wire. One end of the carbon brush wire is vertically inserted into thelow-resistance high-conductivity layer, and crescent arc notches are formed in the front ends of the low-resistance high-conductivity layer and the high-resistance ultrahigh-lubrication layer. The invention also relates to a preparation method of the carbon brush. The preparation method comprises the following steps: step 1, 70-80 parts of natural flake graphite and 5-20 parts of dendritic electrolytic copper powder and 10-15 parts of modified phenolic resin are subjected to stirring, mixing and pinching, pelletizing and grinding, to prepare a mixture A; step 2, 75-85 parts of natural flake graphite and 5-15 parts of high-temperature lubricant molybdenum disulfide and 10-15 parts of resin are subjected to stirring, mixing and pinching, pelletizing and grinding, to prepare a mixture B; andstep 3, 30% of the mixture B is uniformly filled into a mold cavity, 70% of the mixture A is uniformly filled into the mold cavity, and the carbon brush wire is implanted from the rear end of the right side surface in a manner of being perpendicular to the pressing direction.

Description

technical field [0001] The invention belongs to the technical field of massage chair motors, and in particular relates to a composite carbon brush for massage chair motors and a preparation method thereof. Background technique [0002] With the improvement of people's daily life, all kinds of massage chairs have become an indispensable rest and fitness facility for ordinary people's homes, large shopping malls, and airport stations. [0003] The massage chair motor is one of the core components of the whole massage chair. This type of motor is generally a 12-24V DC brushed motor. The massage chair motor is the power source of the entire massage chair. The power is transmitted to the massage ball through the rotation of the motor. Come to massage and decompress people's tired body and mind. Because the environment in which the massage chair is used is extremely quiet, the noise of the massage chair has become a key factor in measuring the comfort of the massage chair. The n...
