Abstract

The invention provides a preparation method of an trapezoidal carbon brush for a seat motor. The method comprises that electrolytic copper powder, natural graphite and phenolic resins powder are mixed uniformly to prepare a high conducting layer mixture; electrolytic copper powder, natural graphite, phenolic resins powder and a lubricant with urotropine are mixed uniformly to prepare a high lubricating layer mixture; the high conducting layer mixture and the high lubricating layer mixture are added successively into a die whose cross section is trapezoidal for compaction, and a pressed compact of the carbon brush is prepared; and sintering and finished product processing are carried out on the pressed compact of the carbon brush to prepare the carbon brush whose cross section is trapezoidal. The carbon brush for the seat motor is formed by combining the high conducting layer mixture with the high lubricating layer mixture and is of a special shape, the side, close to a commutator, is a bending cambered surface, it can be ensured that the front end of the high lubricating layer mixture is protruded and makes contact with the commutator always, and thus, the prepared carbon brush is high in conductive performance, resistant to friction and low in noise.

Description

technical field [0001] The invention relates to a method for preparing a carbon brush for a seat motor, in particular to a method for preparing a carbon brush for a seat motor whose cross section is trapezoidal, and belongs to the field of electric carbon. Background technique [0002] With the popularity of cars in modern society, people have higher and higher requirements for cars. There are various motors inside the car to facilitate the user's operation of the various systems of the car. Taking the seat system as an example, the lifting, forward and backward movement, and angle adjustment of the seat are all driven by motors. This type of motor generally adopts a low-voltage (generally about 12V) DC brushed motor. Since the seat motor is close to the user, the noise requirements are very high. In the noise system, the running-in of carbon brushes and commutators accounts for most of the proportion, so higher requirements are put forward for the materials and structure...
