Abstract
The invention relates to a wear-resistance motor carbon brush. The atom percentage content of the wear-resistance motor carbon brush is 10-20% carbon, 5-10% silicon, 10-20%chromium, 1-10% iron and 40-60% nickel, preferably, the atom percentage content is 12-18% carbon, 5-8% silicon, 15-20%chromium, 2-8% iron and 50-60% nickel, and the atom percentage content is 15% carbon, 5% silicon, 20%chromium, 5% iron and 55% nickel specifically. The wear-resistance motor carbon brush has properties of simple manufacturing, controllable cost and excellent wear resistance performance, effectively improves service life and further effectively reduces cost.
Description
Technical field
The present invention relates to a kind of carbon brush used for electric engine, relate in particular to a kind of wear-resisting carbon brush for electric machine.
Background technology
The carbon brush of motor and the carbon brush of generator are referred to as again carbon brush for electric machine or motor brush, and the appearance of carbon brush for electric machine a little, as the rubber bar of wiping pencil, has wire to draw on top, and volume varies.Effect in motor is exactly to change the sense of current to divide direct current machine and alternating current machine, and direct current machine changes the conductive coil of rotor, thereby changes rotor magnetic pole.Thereby change the motion of motor.Carbon brush is for the commutator of motor or slip ring, as deriving the sliding contact body that imports electric current, and its conduction, heat conduction and greasy property are good, and have the instinct of certain mechanical strength and commutation property spark.Nearly all motor all uses carbon brush, and it is the important composition parts of motor.
Practical experience and the professional knowledge of the inventor based on being engaged in this type of product design manufacture and enriching for many years, and coordinating the utilization of scientific principle, actively research and innovation in addition, to founding a kind of novel wear resistant carbon brush for electric machine, can improve general existing carbon brush for electric machine, make it have more practicality.Through constantly research, design, and after repeatedly studying sample and improving, finally create the present invention who has practical value.
Summary of the invention
Main purpose of the present invention is, overcomes the defect that existing carbon brush for electric machine exists, and a kind of novel wear resistant carbon brush for electric machine is provided, technical problem to be solved is to guarantee that the anti-wear performance of carbon brush for electric machine is good, improve useful life, thereby be more suitable for practicality, and there is the value in industry.
The object of the invention to solve the technical problems realizes by the following technical solutions.The wear-resisting carbon brush for electric machine of one proposing according to the present invention, is made up of the following component of atomic percentage conc: 10% ~ 20% carbon, 5% ~ 10% silicon, 10% ~ 20% chromium, 1% ~ 10% iron and 40% ~ 60% nickel, according to conventional stirring casting technique, obtain this wear-resisting carbon brush for electric machine by above-mentioned element.
Each constituent atoms percentage composition is preferably 12% ~ 18% carbon, 5% ~ 8% silicon, and 15% ~ 20% chromium, 2% ~ 8% iron and 50% ~ 60% nickel,
The carbon that each constituent atoms percentage composition is 15%, 5% silicon, 20% chromium, 5% iron and 55% nickel.
By technique scheme, the wear-resisting carbon brush for electric machine of the present invention at least has following advantages:
Wear-resisting carbon brush for electric machine manufacture of the present invention is simple, and cost is controlled, and anti-wear performance is good, has effectively improved the useful life of carbon brush for electric machine, has further effectively reduced cost.
