    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 sensor system including a movable member, a sensor, and an interpolator. The sensor is configured to generate a first output signal and a second output signal. The first output signal has a first phase angle, the second output signal has a second phase angle, and a first difference between the first phase angle and the second phase angle has a first value. The first value of the first difference includes an offset related to a mechanical incompatibility between the sensor and the movable member. The interpolator is configured to receive the first output signal and the second output signal. The interpolator is operable to apply a compensation factor to generate a third signal having a third phase. The compensation factor has a value that is based on the mechanical incompatibility between the sensor and the movable member.

The clock generation module is configured to generate a modulation signal and an output sampling signal. The modulation signal has a modulation frequency, and the sampling signal has a sampling frequency. The sensor is configured to generate an output signal having an output value. The output signal is modulated by the modulation signal, and the output value includes a sensor output value and an offset value. The conditioning module is configured to receive the output signal, condition the output signal, and generate a conditioned output signal including the sensor output value and the offset value. The output module is configured to receive the conditioned output signal and the output sampling signal. The output sampling signal is operable to sample the conditioned output signal at a value that corresponds to the sensor output value.

    摘要： A planetary gear system (P) includes a sun gear (2), a ring gear (4) a carrier (6) located between the sun and ring gears (2, 4), and planet pinions (8, 10) organized in two arrays and supported on flexpin assemblies (32, 34) in the carrier (6). All of the gearing is helical, with the sun and ring gears (2, 4) having their teeth arranged in at double helix angles (herringbone) and the planet gears (8, 10) at single helix angles. The pinions (8) of the one array engage the teeth of one angle on the sun and ring gears (2, 4) and the pinions (10) of the other array engage the teeth of the other angle on the sun and ring gears (2, 4). Torque transfers through the carrier (6) through two torque paths (a, b)—one to the flexpin assemblies (32) for one array and the other to the flexpin assemblies (34) of the other array—and the paths (a) is stiffer than the path (b). Owing to the helical cut of the teeth the planet pinions (8, 10) of the two arrays exert oppositely directed axial forces (A) on the sun gear (2). The sun gear (2) is free to shift axially or float with respect to the planet pinions (8, 10) of the two arrays, so the axial forces (A) imparted to the sun gear, while opposite, are equal. Hence, the tangential forces (T), which transfer the torque, are likewise equal, notwithstanding the difference in flexibility of the two torque paths (a, b). Even though the carrier (6) may undergo different deflections at the flexpin assemblies (32, 34) for the two arrays of planet pinions (8, 10), the planet pinions (8, 10) of the two arrays transfer torques of equal magnitude.

    摘要： A method of coating spherical components with a coating process in which the spherical components have a surface area includes positioning the spherical components within a containment boundary on a moving member and positioning the moving member within a chamber. The method includes reducing the pressure within the chamber to less than one atmosphere. The method also includes revolving the moving member about a longitudinal axis. The method further includes oscillating the moving member in a direction of the longitudinal axis and commencing the coating process. The oscillating and revolving produce motion of the spherical components within the containment boundary such that an entirety of the surface area of each component is exposed to the coating process.
