    Abstract: A transmission for a power train of a motor vehicle has a first stationary housing part having a first axial contact surface, a second stationary housing part, and a first sealing element on the second stationary housing part, the first sealing element being axially compressible. Additionally, the transmission includes a first planetary gear set including a planet carrier, at least one planet gear, a sun gear, and a ring gear. The planet carrier is fixed relative to one or both of the first stationary housing part and the second stationary housing part. One side of the planet carrier rests against the first axial contact surface, where the first sealing element acts on another side of the planet carrier to axially preload the planet carrier against the first axial contact surface to prevent the planet carrier from tilting relative to a rotation axis of the first planetary gear set.

    Abstract: A positively-engaged infinitely-variable transmission (PE-IVT) system employs a gear assembly including a first helical gear and a second helical gear meshed with the first helical gear. The first helical gear is divided into a plurality of gear segments that can individually move axially along a spline shaft. The PE-IVT system further includes a swashplate configured to constrain the axial motion of the plurality of gear segments. In some embodiments, the system further includes one or more thread-aligners configured to axially align a gear segment with one or more additional gear segments. In some embodiments, the second helical gear is also divided into a plurality of gear segments.

    Abstract: A disclosed fan drive gear system includes a sun gear rotatable about an axis of rotation, a plurality of intermediate gears rotatable about an intermediate gear rotation axis in meshing engagement with the sun gear and a ring gear circumscribing the intermediate gears. A bearing assembly supports at least one of the plurality of intermediate gears and includes a first beam extending in a first direction and a second beam extending from an end of the first beam in a second direction. The bearing surface supported on the second beam such that first and second beams are configured to maintain the bearing surface substantially parallel to the intermediate gear rotation axis during operation.

    Abstract: An epicyclic gear assembly includes a carrier that includes a first plate axially spaced from a second plate by a connector. A first epicyclic gear set is supported adjacent the first plate and includes a first set of circumferentially offset intermediate gears meshing with a first sun gear and a first ring gear. A second epicyclic gear set is axially spaced from the first epicyclic gear set and supported adjacent the second plate and includes a second set of circumferentially offset intermediate gears meshing with a second sun gear and a second ring gear. The first epicyclic gear is set and the second epicyclic gear set maintain relative intermeshing alignment during flexure-induced deformation of the carrier. The first ring gear includes a first set of teeth that extends from a first flexible flange and the second ring gear includes a second set of teeth that extends from a second flexible flange.

    Abstract: An example journal pin includes a generally cylindrical body disposed on an axis having a supply passage. A first chamber and a second chamber are disposed in the generally cylindrical body and are in fluid communication with the supply passage. A recess on an outer diameter of the cylindrical body is in fluid communication with the first chamber and the second chamber. The first chamber and second chamber are each radially outward of the supply passage and including an outlet to the recess. The first chamber and second chamber each have a first section radially inward of a second section. A cross sectional area of the second section is greater than a cross sectional area of the corresponding first section.
