摘要： PROBLEM TO BE SOLVED: To prevent an increase in lead-wire fitting resistance in a metal graphite brush that contains a metallic-sulfide solid lubricant but does not contain lead. SOLUTION: A brush body 4 of the metal graphite brush 2 is formed of a commutator side member 6 that contains graphite, copper and a metallic- sulfide solid lubricant, and a lead-wire embedding member 8 that contains graphite and copper but does not contain a metallic-sulfide solid lubricant. A lead wire 10 is fitted to the lead-wire embedding member 8 that does not contain a metallic-sulfide solid lubricant.

摘要： PROBLEM TO BE SOLVED: To join at low cost by installing a commutator body for fixing both segments joined in a ring shape, containing metal in a projection part of a carbon segment, and caulking the projection part inserted into a through hole of a metal segment. SOLUTION: The content of metal in a projection part is preferable to be 60-100 wt.% based on the weight of carbon. A projection part 3 formed in each carbon segment of a carbon member is inserted into a through hole formed in each metal segment of a metal member 10, and the projection part 3 is caulked. The carbon member and the metal member 10 joined are fixed to a commutator body 30 with a claw 14 formed in the metal segment. The carbon member and the metal member 10 fixed to the commutator main body 30 are divided into a plurality of segments having the same shape with a blade. By dividing, the carbon segments and the metal segments are arranged in a ring shape on the commutator body 30.

摘要： PURPOSE:To simplify constitution by dividing a powder-compressing die into a movable die and a fixed die, providing a powder molding chamber between the surface of junction between the dies, providing the fixed die with a sliding hole extending in a direction perpendicular to the direction of compression, and passing a lead through the hole thus processing the powder. CONSTITUTION:As upper 13 and lower 14 cam bodies are rotated together with a main spindle 12, an upper punch 26 rises, a lower punch 31 drops, and a lever 38 is rotated in the direction of the arrow so that a feeder 37 is driven up to a position where it covers the molding chamber 22a of a die 22. As the punch 31 is driven in the downward direction, powder P is fed to the molding chamber 22a from the feeder 37. Then the end of a lead 55 projects from the end of a guide pipe 56 by a predetermined size and is positioned so as not to project into the molding chamber 22a. When the feed of the powder P is completed, the lever 38 is rotated in the reverse direction to retreat the feeder 37 and to advance the guide pipe 56, thereby forcing the end of the lead 55 to project into the molding chamber 22a. Then rotation of the main spindle 12 causes the upper punch 26 to fall and the lower punch 31 to rise, thus compression molding the powder P inside the molding chamber 22a.

摘要： PROBLEM TO BE SOLVED: To provide a brush, a commutator and a commutation mechanism that are superior in commutation properties and durability. SOLUTION: A commutator 5 in a DC electric motor has a plurality of commutator pieces 6 that comes into contact with a brush 4, each of the commutator pieces 6 a low resistance layer 61 made up of a low-resistance material, a high-resistance layer 62 made up of a high resistance material of which resistivity is higher than that of the low-resistance material. A low resistance material contains a carbon material and a binder, and a high-resistance material contains a carbon material and a binder and a boron nitride (BN) as an inorganic substance. The mixing ratio of boron nitride to the total quantity of the high resistance material is designed to be greater than 20 wt%. COPYRIGHT: (C)2006,JPO&NCIPI

摘要： PURPOSE:To suppress the friction and magnetic noise of a brush by a method wherein at least one of boundary lines between the surfaces between two layers and friction planes of the brush is so provided as to have an inclination with respect to the front friction end plane of the brush. CONSTITUTION:A preliminary molded product 71 which is molded into a right- angle triangular pyramid is inserted into a mold space 5. At that time, the molded product 71 is so inserted as to have the slope plane of the right-angle triangular pyramid exposed in the upper part of the mold space 5. The right- angle triangular pyramid has three rectangular planes and one of them is the slope plane. One of the two rectangular planes except the slope planes is brought into contact with the bottom of the mold space 5. Then low resistance material powder 72 is supplied by a feeder to fill the mold space and, when an upper punch 3 is made to descend, a lower punch 2 is made to ascend simultaneously to perform compression molding. The preliminary molded product 71 is compressed and combined with the supplied powder 72. Then the upper punch 3 is made to ascend and a laminated brush 10 is pushed up by the lower punch 2 and a lead wire 6 is cut off to obtain the laminated brush 10.
