摘要： A method of designing a roller bearing is disclosed upon clarifying mechanisms of damage patterns in respect of two kinds of brinelling, involved in the bearing, wherein white-banded flaking (brittle flaking) is a plastic instability phenomenon appearing under high-speed deformation accompanied by adiabatic shear deformation status with the resultant occurrence of adiabatic shear band (also called white band) inside material of the bearing. This enables all of the damage patterns to be determined upon making comparison between shear strain and shear strain rate, occurring inside the bearing, and discriminated values.

摘要： An automotive alternator includes a rotary shaft, a pulley, a stator, a rotor, and a magnetic fluctuation suppressor. The pulley is provided on the rotary shaft to transmit rotating power from an engine to the rotary shaft. The stator includes a stator winding. The rotor is mounted on the rotary shaft and configured to provide a first rotating magnetic field to the stator. The magnetic fluctuation suppressor includes a magnetic body and a magnetic source. The magnetic body is mounted on the rotary shaft such that the magnetic body is rotatable along with the rotary shaft at a rotational speed different from that of the rotary shaft. The magnetic source is fixed to the rotary shaft so as to create a second rotating magnetic field which induces a magnetic attraction between the magnetic body and the magnetic source, by which fluctuations in rotational movement of the rotary shaft are suppressed.

摘要： A vehicle alternator for generating electric power is driven by an engine mounted on a vehicle driven through a driving belt. The alternator has a pulley part joined to and directly receiving a driving force from the engine through the driving belt, a field magnet part located in separation from the pulley part, a rotation speed changing part placed between the pulley part and the field magnet part. The rotation speed changing part converts the number of revolutions between the pulley part and the field magnet part. The rotation speed changing part decreases a speed changing ratio “S” according to increasing of the number of revolutions of the engine, where the speed changing ratio “S” is obtained by dividing the number of revolutions of the field magnet part by the number of revolutions of the pulley part.

摘要： According to the present invention, a rolling bearing for supporting a rotary shaft of an automotive accessory includes an inner ring, an outer ring, a plurality of rolling elements interposed between the inner and outer rings, and grease. The grease has a withstand pressure greater than a predetermined range in which plastic deformation of at least one of surfaces of the inner and outer rings and rolling elements occurs in absence of an elastohydrodynamic lubrication film of the grease on the surface. With such a configuration, it is possible to reliably avoid plastic deformation of the inner and outer rings and rolling elements regardless of presence of elastohydrodynamic lubrication films between the inner and outer rings and the rolling elements. As a result, brittle flaking is reliably prevented from occurring in the rolling bearing.
