摘要： A camshaft phase shifting device (30) includes a coaxially arranged three-shaft gear system, having an input shaft (16), an output shaft (14), and a control shaft (34) for adjusting the phase angle between the input and output shafts (16, 14). The control structure is a torque-based control structure. The dynamic response of the gear system and thus the desired phase angle of a camshaft (12) associated with the output shaft (16) is controlled and adjusted by a controller (40) which produces a torque command based on received signals. These signals include, but are not limited to, cam shaft phase angle error signal, torque load, and/or angular position signal of the camshaft (12), and relative speed signal between the input and output shafts (16, 14). The torque command is converted by an electric machine (32) into an electro-magnetic torque exerting on the control shaft (34) of the camshaft phase shifting device (30), and includes two parts, a feed forward part to compensate for the known disturbances in system torques and a feedback part to compensate for unknown disturbances.

摘要： An eccentric planetary traction drive transmission (A) which includes at least two planetary rollers (3 & 4), sun roller member (2), and a carrier member (27). One of the planetary rollers (3, 4, or 5) is flexible and is positioned between and in contact with an outer ring member (1) and the sun roller member (2). Rotation of either the outer ring member (1) or the sun roller member (2) wedges the flexible planetary roller (3, 4, or 5) within a convergent wedge gap (23) which squeezes the flexible planetary roller (3, 4, or 5) between the outer ring member (1) and the sun roll member (2). Friction between the flexible planetary roller (3, 4, or 5), the sun roller member (2), and the outer ring member (1) transmits rotational motion and torque between the outer ring member (1) and the sun roller member (2). The other at least one supporting planetary roller (3, 4, or 5) is a supporting roller which supports the sun roller member (2) and the carrier member (27). A plurality of bearings (26) supports the sun roller member (2) within the outer ring member (1) and the at least one supporting planetary roller (3, 4, or 5).

摘要： A roller bearing includes an inner race ring, an outer race ring, and a roller arranged between and in contact with the inner and outer rings. The bearing has a flange (31,131) on the inner race ring at one axial end, and a flange (21,121) on the outer race ring at an opposite axial end. One of the flanges, and/or an end of the roller, includes at least one principal segment (53,153) intermediate two additional segments (52,152;54,154). The principle segment is tangentially blended with the two additional segments, and the principle segment has a first curvature that is different from the respective curvatures of the two additional segments. A non-elliptical contact footprint can be obtained by composite profiles at the contact location between the roller end and the mating flange face.
