Abstract: An epicyclic drive (A) has its planet gears (6) integrated into separately built planet assemblies (B). Each planet assembly (B), in addition to its planet gear (6), includes a pin (34) which extends through the planet gear (6) and an antifriction bearing (36) located between the gear (6) and the pin (34). The outer raceways (72, 74) for the bearing (36) are machined into the gear (6), whereas the inner raceways (52, 54) are machined into the pin (34). The bearing (36) also has rolling elements (82) organized in two rows between the inner and outer raceways. The pins (34) have mounting ends (40, 42) which lie beyond the ends of the planet gear (6) to anchor the planet assembly (B) in a carrier (8). The bearing (36), inasmuch as it is assembled separately, is set with considerable precision, preferably in preload, so the planet gear (6) does not skew with respect to sun gear (2) and ring gears (4) with which it meshes during operation at the epicyclic drive (A).

Abstract: 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).

Abstract: An epicyclic gear system (A) has a sun gear (2), a ring gear (4) located around the sun gear, and planet gears (6) located between and engaged with sun and ring gears. In addition, it has a carrier (8) including a carrier flange (30) offset axially from the planet gears, carrier pins (34) projecting from the carrier flange into the planet gears, and bearings (72) between the planet gears and the carrier pins so that the planet gears rotate on the pins. Each bearing includes an inner race (46) having tapered raceways (56) presented away from the carrier pin, opposing tapered raceways (24) on the ring gear, and tapered rollers (70) organized in two rows between the raceways. Whereas the carrier pin is cantilevered from the carrier flange, the inner race is cantilevered from the carrier pin remote from the carrier flange, and this insures that the axes (Y) about which the planet gears rotate remain parallel to the central axis (X) of the system.

Abstract: A chuck (A) grips the housing (2) of a hub assembly (B) to hold it fast and further engages a hub spindle (20) that is within the housing and rotates the spindle on a bearing (6) that is between it and the housing so that a flange (10) on the hub (4) may be machined with precision. The chuck includes a fixed base (76) that carries jaws (114) which clamp down on the housing to firmly hold the housing. It also includes a rotatable base (124) and an arbor (164) carried by the rotatable base and engaged with the spindle of the hub to impart the rotation of the hub. The arbor can shift radially with respect to the rotating base to accommodate misalignment between the axes of rotation for the hub and the rotating base. A bearing (188) lies between the arbor and rotating base to resist an axially directed force applied to the arbor to expand it in the hub spindle.

Abstract: A tapered roller bearing (26, 28) that is well-suited for supporting a pinion in an automotive differential (A) has a cone (44) and a cup (46) provided with opposed raceways (52, 64) that are crowned. The cone also has a thrust rib (54) provided with a rib face (58) at the large end of its raceway. In addition, the bearing has tapered rollers (48), each having a tapered side face (70) that is crowned and a large end (72) that is spherical. The rollers (48) contact the raceways (52, 64) along their crowned side faces and the rib face along their spherical end faces. The ratio of the roller length (C) to the large end diameter (D) is less than 1.5. The crowning on the raceway (52, 64), together with the crowning of the roller side face (70) provide total end relief ranging between 700 µin. and 1500 µin. per inch. The centers of contact between the side faces (70) and raceways (52, 64) are offset toward the rib face (58). The height of the rib face (58) amounts to 30% - 45% of the diameter of the large ends (72) of the rollers (48). The radius of the spherical large end face (52) for a roller exceeds 90% of the roller apex length. The runout in the large end faces is less than 50 µin. and the center of contact between the end face (72) of each roller (48) and the rib face (58) is between ranges between 0.02 and 0.04 in. All of this contributes to low torque demands by the bearing itself and wear.

Abstract: A front or rear torque transfer module system (A) for an all-wheel drive vehicle (V) includes a housing (5) containing two rotating shaft members (10 & 15) connected by a clutch (113). The clutch (113) is activated when a braking mechanism such as an electromagnetic, hysteresis or eddy current brake (260) modulates the relative rotation between a clutch pressure plate (175) and the second rotating shaft member (15). The difference in relative rotation forces two opposing ramped surfaces (65) into opposition to induce the clutch pressure plate (175) to compress a set of interleaved clutch discs (160 & 165) thereby transferring rotational motion between the first rotating shaft member (10) and the second rotating shaft member (15).
