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： 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.

摘要： The present invention provides a compact, efficient and noiseless alternator for an automotive vehicle which employs a double-layer coil arrangement in a slot for eliminating coil end interference as well as improving the space factor. An automotive alternator comprises a Lundel-type core rotor with 16 poles, and a stator with toothed portions of 96 poles spaced by slots. U-shaped conductor segments are installed in the slots. One portion of the conductor is accommodated in an outer layer portion of a predetermined slot, while the other portion is accommodated in an inner layer portion of a slot phase shifted by an electric angle of 180°. In this manner, all of the slots are separated into the inner and outer layers to accommodate a plurality of conductor segments. These conductor segments are connected only at one side of the stator to form a total of twelve wavy winding coils. These twelve wavy winding coils are divided into three groups each consisting of a serial connection of four wavy windings to constitute one phase of a three-phase stator coil.
