A dispensing device for dental material, which includes a planetary gear drive with at least three planet gears in engagement with an annulus gear. The annulus gear is radial float-mounted relative to the planet gears. A radial force applied on the annulus gear urges the annulus gear into an off-center relationship with respect to an imaginary circle on which the planet gears are arranged.

An epicyclic gearbox that includes a sun gear, a ring gear, and a plurality of planet gears. The planet gears rotatably couple to the ring gear and the sun gear. Pins coupled to or formed as part of a carrier extend into the planet gears. A sleeve overhangs a notch defined, in part, by at least one of the pins. The pins, the carrier, the sleeve, or any combination of one or more of the pins, the carrier, or the sleeve are capable of flexing.

Speed reduction gear for an aircraft turbomachine. The reduction gear has a main axis and planet carrier having a cage and a cage carrier, a sun gear located in the cage and centred on the main axis, an annular row of planet gears arranged around the main axis and the sun gear and meshed with the sun gear, and a ring gear arranged around the axis and the cage and meshed with the planet gears. The cage and the cage carrier are connected to each other by connections whose bending flexibility is optimised.

A planetary gear train including a ring gear defining a central axis; a plurality of planet gears, each planet gear being rotatable about a respective planet axis and meshing with the ring gear, and each planet gear including a conical and helical planet gear toothing defining a conical direction; a planet carrier rotationally supporting the planet gears for rotation about the planet axes, the planet carrier being axially displaceable along the central axis; and a carrier forcing device arranged to force the planet carrier along the central axis in the conical direction. A gearbox for an industrial robot, the gearbox including a planetary gear train, and an industrial robot including a planetary gear train or a gearbox, are also provided.

A planet gear housing assembly in an epicyclical gear assembly comprises an aft planet gear assembly and a forward planet gear assembly. The aft planet carrier assembly comprises an aft flange defining a central aperture and an annular mounting flange positioned forward of and coaxial with said central aperture, said mounting flange forming a forward facing mounting surface comprising a curvic structure. The forward planet carrier assembly comprises a forward flange defining a central aperture and an annular mounting flange positioned aft of and coaxial with said central aperture, said mounting flange forming an aft facing mounting surface comprising a curvic structure. The curvic structures of the mounting surfaces are positioned relative to each other to thereby form a static curvic joint.
