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： A rolling bearing is adapted for an auxiliary device driven by an internal combustion engine via a belt. The rolling bearing comprises an inner race, an outer race, and a plurality of rolling elements disposed between the inner race and the outer race for rolling capabilities. A substantially half of a tolerance value of a clearance in a radial direction of the rolling bearing falls in a negative value, under a condition where the rolling bearing is mounted in the auxiliary device.

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.
