    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： 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 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： A method of calculating torque of a Lundell-type synchronous generator is disclosed in which only power generation output current and a rotational speed are input for calculation of the amount of electric power and the amount of losses for thereby enabling calculation of power generating torque, based on a sum of the amount of electric power and the amount of losses, which is generated as an output. The present method establishes formulae enabling calculation based on only output current and the rotational speed, enabling a minimal number of inputs to shorten a calculation time interval.

    摘要： In an on-vehicle alternator using a serpentine drive system with a poly-V belt, a damping ratio of the alternator is rendered 0.5 or more as other auxiliary machines by considering six contributors to the damping ratio (i.e., pulley radii, a belt span, a moment of inertia, the number of belt ribs, an elasticity modulus of a single-body belt, and a hysteresis loss of a single-body belt). In one example, a pulley ratio of the alternator relative to an engine crankshaft pulley is rendered 2 or less. In another example, belt span lengths on both sides of the alternator are reduced by fixing the alternator to an on-vehicle engine using a side mounting system. The damping ratio of the alternator is thus increased to 0.5 or more, leading to a significant reduction in vibration in the serpentine drive system fixed to the on-vehicle engine.

    摘要： In a design method for a belt transmission system, tensile forces between pulleys are calculated from a total layout of the belt transmission system, such as a spring constant of a belt, a distance between the pulleys, an initial tensile force, a driving force for the respective pulleys to be calculated from a load of the respective pulleys, and so on. A coefficient of static friction is calculated from the tensile forces at the pulling and un-pulling sides and a contact angle. Then the coefficient of the static friction is compared with a maximum coefficient of the static friction, and it is determined that no slip occurs when the coefficient of the static friction is smaller than the maximum coefficient of the static friction.
