Abstract

The invention provides a radial carbonaceous commutator and a manufacturing method thereof. The radial carbonaceous commutator comprises a cylindrical insulating supporter, a plurality of metal conductor connecting pieces and the same amount of carbonaceous arc-shaped bodies, wherein the carbonaceous arc-shaped bodies enclose to form a carbonaceous cylinder having a plurality of second cutting grooves, the axial end surface on which the plurality of carbonaceous arc-shaped bodies and the plurality of metal conductor connecting pieces are in conductive connection is a closed end surface, the other end of the carbonaceous cylinder is open, an empty cup cavity used for accommodating the supporter is formed between the opening and the closed end surface, a through hole with the diameter less than the inner diameter of the empty cup cavity is formed in the center of the closed end surface, and the plurality of metal conductor connecting pieces are welded and fixed on the closed end surface, in which the through hole is formed, of the carbonaceous cylinder and form a plurality of fan-shaped welding connection surfaces, thereby increasing the welding area between the carbonaceous cylinder and the metal conductor connecting pieces, improving the strength stability of assembly in the axial direction, and guaranteeing the strength requirements required for injection-molding the supporter inside the carbonaceous cylinder.

Description

technical field [0001] The invention relates to the field of commutators, in particular to a radial carbon commutator and a manufacturing method thereof. Background technique [0002] The commutator, also known as the commutator, is a part of the DC permanent magnet series motor in order to allow the motor to continue to rotate. The commutator is generally divided into planar commutator and radial commutator according to its structure and the working surface of the brush. Among them, the commutator segment of the planar commutator is fan-shaped, and the commutator slot is a radial slot. The brush slides over the end face of the planar commutator; the commutator segment of the radial commutator is arc-shaped, and the commutation groove is axially cut, and the brush slides over the cylindrical surface of the radial commutator. . The commutator segments of traditional commutators are generally made of copper material. With the continuous change of the use environment of the c...
