Abstract: A method comprises accessing a vibratory device having a rotor and first and second eccentric weights. The first weight is initially attached to the rotor's shaft in a manner such that its center of the mass is offset from the shaft in a first radial direction. The second weight is initially attached to the shaft in a manner such that its center of the mass is also offset in the first radial direction. The method further comprises reorienting the first and second weights relative to the shaft in a manner such that their centers of the mass are offset in a second radial direction. By performing these steps, the location of greatest bearing surface wear rate on the shaft is circumferentially relocated about the shaft. As such, the service life of an eccentric weight vibratory device is thereby extended.

Abstract: In an in-wheel motor driving device, since an involute speed reduction gear with a small difference in number of teeth which can be made small in size can be disposed on an inner side of an inner rotor type motor, a size of the in-wheel motor driving device in the direction of a rotational axis can be reduced. Further, in the inner rotor type motor, since a first stator is disposed so as to face a radially outer side of a large-diameter rotor, heat generated in the first stator is easily dissipated. On the other hand, in an outer rotor type motor, since a second stator is disposed so as to face a radially inner side of a small-diameter rotor, a torque radius of the small-diameter rotor can be made large, thereby making it possible to ensure a large torque capacity. Because of this, the outer rotor type motor can be made smaller in diameter than the inner rotor type motor, thereby making it possible to ensure a large space within a wheel.
