Abstract
The invention relates to a starting motor carbon brush for a vehicle engine and a making method of the same. The starting motor carbon brush for the vehicle engine is characterized in that the starting motor carbon brush for the vehicle engine comprises the following components: a mixed graphite powder, a copper powder, molybdenum disulfide and cerium oxide, wherein the mixed graphite powder comprises the following components in percentage by weight: graphite powder, epoxy resin and phenolic resin. The making method of the same comprises the following steps that the phenolic resin and alcohol which have a same amount are firstly mixed for 15 minutes; the epoxy resin is added into the mixing phenolic resin and mixed with the phenolic resin together for 15 minutes so as to make composite resin; the mixed composite resin is mixed with the graphite powder at the temperature of 90 DEG C so as to make the mixed graphite powder; the copper powder, the molybdenum disulfide and the cerium oxide are added into the mixed graphite powder in a mode of dry powder; and the copper powder, the molybdenum disulfide, the cerium oxide and the mixed graphite powder are pressed to make the starting motor carbon brush for the vehicle engine after being mixed in a dry type mixer. The starting motor carbon brush for the vehicle engine has the advantages that with the selection of epoxy phenolic composite resion as an adhesive, the strength of the carbon brush is strengthened; with the molybdenum disulfide as a lubricant, the problem of lubrication at the starting instant is solved; and with the cerium oxide as a grinding agent, the electrical property of a motor keeps a stable level.
Description
Technical field
The present invention relates to a kind of automobile engine starting carbon brush for electric machine and production method thereof.
Background technology
Auto industry has become the pillar industry of China, and the technical merit of whole automobile industry improves constantly, all in addition parts all towards advancing with the direction in life-span with automobile.As the carbon brush of the main consumable accessory of engine start motor, its life-span length has determined the life-span of starter motor basically, has also become to influence the key factor of engine bulk life time.In order to reach the target with the life-span, domestic carbon brush industry is being done effort separately on different directions.But carbon brush is except wear problem, and main it is an electric conductor, all can have influence on size of current to its any change, thus the staring torque of having influence on and rotating speed.Its two aspect is mutual restriction often, and along with the development of Domestic Automotive Industry, the requirement of two aspects is all improving constantly.More satisfactory solution motor performance and carbon brush life-span this to contradiction, particularly on high-performance high-quality automobile, handling this well is carbon brush manufacturing enterprise problem demanding prompt solution to contradiction.
Summary of the invention
The objective of the invention is to solve the problem of the existing wearing and tearing of automobile engine starting carbon brush for electric machine and conductivity mutual restriction in the prior art, a kind of automobile engine starting carbon brush for electric machine and production method thereof are provided.The present invention designs a kind of automobile engine starting carbon brush for electric machine, it is characterized in that being made up of by weight percentage following constituent: mixing graphite powder 20-40%, copper powder 55-75%; Molybdenum bisuphide 2-4%, cerium oxide 0.5-1.5%, the summation of mentioned component is 100%; Described mixing graphite powder is made up of following constituent by weight percentage: graphite powder 78-82%; Epoxy resin 2-4%, phenolic resins 15-20%, the summation of mentioned component is 100%.A kind of automobile engine starting carbon brush for electric machine preparation method; It is characterized in that forming: prepare mixing graphite powder earlier by the following step; Phenolic resins and alcohol with equivalent mixed 15 minutes earlier; Phenolic resins during epoxy resin add mixed mixed together was again processed compound resin in 15 minutes, then compound resin that mixes and graphite powder was mixed and made into mixing graphite powder under 90 ℃ temperature; Copper powder, molybdenum bisuphide and cerium oxide are joined in the mixing graphite powder with dry powder form, mix back compacting automobile engine starting carbon brush for electric machine with doing in the dry mixer.Advantage of the present invention is to select for use the epoxy novolac compound resin to make binding agent,
With the cohesive force of epoxy resin reinforcement phenolic resins, improve the intensity of carbon brush.Use molybdenum bisuphide to be lubricant, efficiently solved the lubrication problem that carbon brush starts moment.Used cerium oxide to be grinding agent, appropriateness has been cleared up the oxide-film on the motor commutator, makes the electrical property of motor keep maintenance level.
Below in conjunction with instance the present invention is made detailed operation instruction.
