Embodiment Construction

[0010] The present invention will be described in detail below in conjunction with specific embodiments

[0011] A composition for making a new electric brush, including coke powder, aluminum powder, copper powder, resin, adhesive and lubricating material. The weight ratio of coke powder, aluminum powder, copper powder, resin, binder and lubricating material is: 5:2:1:1:2:1. The composition is sintered at a high temperature of 1200°C-1600°C. The temperature is 1400°C.

[0012] In summary, the present invention saves cost and is easy to operate.

[0013] The above descriptions are only preferred embodiments of the present invention, and the scope of protection of the present invention is not limited to the above embodiments, but all equivalent modifications or changes made by those of ordinary skill in the art according to the disclosure of the present invention should be included within the scope of protection described in the claims.

Abstract

The invention discloses a composition for manufacturing a novel electric brush. The composition comprises the coke powder, aluminum powder, copper powder, resin, a binding agent and a lubricating material according to a weight proportion of 5: 2: 1: 1: 2: 1. The quantity relative ratio of the composition is 6: 2: 1: 3: 1: 1: 1 Therefore, the composition disclosed by the invention is long in service life and better in self-lubricating property. Therefore, the novel electric brush manufactured by the composition is saved in cost, easy to operate and longer in wear-resisting life.

Description

technical field [0001] The present invention relates to a composition, in particular to a composition for making electric brushes. Background technique [0002] A brush is a conductive component that makes sliding contact with a moving part to form an electrical connection. The brush is used on the commutator or slip ring as a sliding contact body for importing and exporting current. It has good electrical conductivity, thermal conductivity and lubricating properties, and has certain mechanical strength and reversible spark instinct. Almost all DC motors and commutation motors use brushes, which are an important component of the motor. Brushes are more and more widely used in daily life. Many household appliances need to use brushes, such as vacuum cleaners, household Crusher etc. However, common brushes have the disadvantages of short service life, non-wear resistance, and large sparks. Contents of the invention [0003] The technical problem to be solved by the prese...
