  • Patent number: 7348700
    Abstract: An automotive alternator according to the present invention includes a rotary shaft, slip rings, a brush holder, brushes, a cover, a seal member, a cooling air flow path, and a water shield. The slip rings are fixed to an end portion of the rotary shaft. The brushes are accommodated in the brush holder and so held by the brush holder as to establish sliding contacts with the slip rings to excite the automotive alternator. The cover covers the end portion of the rotary shaft, the slip rings, the brush holder, and the brushes. The seal member is interposed between the brush holder and the cover. The cooling air flow path is formed between the seal member and one of the brush holder and the cover to supply cooling air to the brushes. The water shield works to prevent water from entering into an entrance of the cooling air flow path.

  • Patent number: 6875140
    Abstract: Engine auxiliary unit driving equipment for transmitting an engine driving force from a crank pulley to a plurality of engine auxiliary units include an alternator and a driven poly-V pulley, provided at least in the alternator, has a plurality of grooves extending in a circumferential direction. A poly-V belt, which has a plurality of projections extending in a longitudinal direction to correspond to grooves of the poly-V pulley, bridges between a crank pulley and the poly-V pulley. The poly-V belt is substantially divided in an axial direction of the driven poly-V pulley into two pieces each having plural pieces of the projections. Accordingly, a tensile strength acting in a width direction of the poly-V belt is substantially divided midway between the divided poly-V belts to reduce cracking in the round poly-V belt, resulting in longer life of the poly-V belt.

  • Patent number: 6664699
    Abstract: A rotary electric machine has a brush assembly that defines a slip ring cavity enclosing slip rings and brushes. The brush assembly provides two different outlets for particles and cooling air. The first outlet is located on a side with respect to a shaft and is directed in an axial backward direction. The second outlet is located on a bottom and is directed in a radial downward direction. The second outlet is close to a fan for inducing airflow in the slip ring cavity.

  • Patent number: 6563241
    Abstract: In an a.c. generator for vehicles, an output terminal connected to a rectifier circuit unit has a seat surface on which an electric cable for connection with a storage battery is seated. The seat surface is positioned outside a rear cover and an insulating member in the longitudinal direction of the output terminal. The electric cable is tightened to the seat surface by a nut engaged with the output terminal, while holding the electric cable from contacting the insulating member. Thus, the insulating member is restricted from being deformed and the nut is restricted from loosening even when the insulating member contracts.

  • Patent number: 6515398
    Abstract: In an alternator for use in an automobile, a passage for ventilating air around slip-rings is formed on a rear cover that covers a rear end of the alternator where the slip-rings are disposed. A brush device for supplying exciting current to a rotor through the slip-rings is mounted around the slip-rings, and the axial rear end of the brush device is covered with the rear cover. A space enclosed by the brush device and the rear cover is formed around the slip-rings, and air in the enclosed space is ventilated through the ventilation passage when the alternator is driven.
