摘要： A bearing assembly having an inner race ring (14) that defines an inner raceway and an outer race ring that defines an outer raceway on which the plurality of rolling elements (22) roll. The bearing raceways are machined using surface finishing operations to create preferred surface profiles and textures for improving lubrication performance. The profile of the raceway is initially created using a first grinding process to form a rough surface profile including a rough central band (34) and rough recessed side bands (38). A second grinding process is used to smooth the central band. This raceway surface profile increases lubrication performance.

摘要： An integrated electric motor and traction drive (1) is disclosed. The device comprises an electric motor (100) and a traction drive (200). The electric motor (100) provides power at a high angular velocity to a sun roller (153). The sun roller (153) transfers the power to the traction drive (200) which reduces the power to a lower angular velocity and delivers it via an output shaft (252).

摘要： A transmission includes two planetary units (U1, U2) and two variators (V1, V2), all connected together such that power can be transferred between an input (I) and an output (O) in a compound-split mode or an output-split mode. In the compound-split mode the two planetary units are joined together at two connections, creating two compound member branches and two single member branches. Except when the transmission operates at its nodes, power transfers through a mechanical path and also through a variator path located in part between the two variators, one of which functions as a motor and the other as the source of power for the motor. At the nodes all power transfers through the mechanical path and the transmission has its greatest efficiency. In the output-split mode, which exists at an output speed below that identified with the first node, one of the compound member branches is interrupted so that the two planetary units are only coupled at one of the compound member branches. In this mode some of the power transfers through the first planetary unit, and some transfers through the variators and the second planetary unit.
摘要翻译：变速器包括两个行星单元（U1，U2）和两个变速器（V1，V2），全部连接在一起，使得功率可以在复合分离模式或输出端之间在输入（I）和输出（O） -split模式。在复合分割模式中，两个行星单元在两个连接处连接在一起，形成两个复合构件分支和两个单个构件分支。除了传输在其节点上操作之外，功率通过机械路径传输，并且还通过位于两个变换器之间的变换器路径，其中一个变换器用作电动机，另一个用作电动机的功率源。在节点处，所有功率通过机械路径传输，传输效率最高。在输出分离模式中，其输出速度低于与第一节点识别的输出速度，复合构件分支之一被中断，使得两个行星单元仅耦合在复合构件分支之一处。在这种模式下，一些功率通过第一行星单元传递，一些传递通过变速器和第二行星单元。

摘要： A double row thrust bearing assembly (10) includes a bottom plate (11) having inner and outer conical raceways (12, 13), a top plate (14) with a flat raceway (15), and respective sets of identically formed inner and outer rollers (16, 17) mounted on respective inner and outer cages (18, 19). When the bearing is fully assembled, the apices of the inner and outer rollers directed at the same point (A) on an axis (X) of the bearing. Various relationships with respect to the size and shapes of the rollers are determined in order to maximize the bearing assembly's load carrying capacity while occupying the same spatial envelope as that of a single row thrust bearing assembly (BA) which can only support a lesser load.

摘要： An eccentric planetary traction drive transmission (A) in which a planetary roller (3) is positioned between and in contact with an outer ring member (1) and a sun roller member (2). Rotation of either the outer ring member (1) or the sun roller member (2) wedges the planetary roller within a convergent gap which squeezes the planetary roller (3) between the outer ring member (1) and the sun roll member (2). Friction between the planetary roller (3), 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). An internal carrier (4) with a plurality of bearings (18 & 19) supports the sun roller member (2) within the outer ring member (1).

摘要： A roller bearing (10) defines a bearing axis (34) and a radial plane (52) oriented parallel with the bearing axis. The roller bearing (10) includes an inner ring (42) having an inner raceway (44) and an inner flange (46) extending from the inner raceway. The inner flange (46) includes an inner guide surface (48). The roller bearing (10) also includes a plurality of rollers (22) in rolling engagement with the inner raceway (44) about the bearing axis (34). Each roller (22) includes a first end surface (24a) in engagement with the inner guide surface (48) of the inner flange (46) as the plurality of rollers (22) move relative to the inner ring (42). The first end surfaces (24a) of each roller (22) define a curvature such that a ratio of a first principal effective curvature (Rx) radius in a plane perpendicular to the radial plane ()52) and a second principal curvature radius (Ry) in the radial plane (52) is no less than 3.0.

摘要： A wedge loading mechanism (1) for an eccentric planetary traction drive in which a roller having a flexibly mounted shaft (4) is positioned between two raceways (2 & 3) forming a convergent wedge. Rotation of either of the two raceways (2 & 3) wedges the roller within the convergent wedge squeezing the roller between the two raceways (2 & 3) thereby transmitting rotational motion and torque between the two raceways (2 & 3). The flexibly mounted shaft (4) generates differences between an effective supporting stiffness of the roller and an contact effective stiffness at the points where the roller contacts the two raceways (2 & 3). The difference in the effective stiffness allow the roller to operate efficiently at smaller convergent wedge angles.
摘要翻译：一种用于偏心行星牵引驱动器的楔形装载机构（1），其中具有柔性安装的轴（4）的辊定位在形成会聚楔的两个滚道（2和3）之间。两个滚道（2和3）中的任一个的旋转楔住了会聚楔块内的辊子，挤压辊子在两个滚道（2和3）之间，从而在两个滚道（2和3）之间传递旋转运动和扭矩。柔性安装的轴（4）产生辊的有效支撑刚度与辊接触两个滚道（2和3）的点处的接触有效刚度之间的差异。有效刚度的差异允许辊以较小的收敛楔角有效地运行。
