Abstract: A gear mechanism including a rotatably supported first gear, a second gear meshed with the first gear, the second gear rotatably supported around a second axis line and having a smaller conical angle than the first gear, a holder which supports the second gear in a rotatable manner with a bearing, and a shim for the second gear which is placed at a position between the holder and a gearbox and which can adjust a position of the second gear in the direction along the second axis line. The second gear shim includes a through hole in which the holder is located so that the holder penetrates the second gear shim, and a path which extends from an outer circumference edge of the second gear shim to the through hole, where the path allows the holder to pass in a direction crossing the second axis line.

Abstract: A planetary gear assembly including an input sun gear; a first plurality of planetary gears driven by the input sun gear; a planet carrier coupled with the first plurality of planetary gears; and an output sun gear wherein rotation of the input sun gear drivingly rotates the planet carrier at a first rotational speed and the output sun gear at a different second rotational speed. An output shaft fixed to the planet carrier and the output sun gear are simultaneously rotated about a common longitudinal axis at the different speeds by rotation of the input sun gear. The output sun gear is accessible through a longitudinal passage in the output shaft. A PTO shaft is drivingly couplable with the output sun gear by inserting a first end of the PTO shaft into longitudinally extending passage or with the planet carrier by inserting the second end of the PTO shaft.

Abstract: A drive assembly including a housing having an opening, a shaft supported for rotation by a bearing assembly received in the opening of the housing, and at least one gear fixed for rotation with the shaft. The bearing assembly includes a bearing that is axially fixed to the shaft, and a sleeve having a tubular section, a radially inwardly extending flange at a first end of the tubular section and a radially outwardly extending flange at a second end of the tubular section. The bearing is received in the tubular section and abuts at least a portion of the tubular section and the radially inwardly extending flange. The radially outwardly extending flange abuts a surface of the housing surrounding the opening of the housing thereby setting an axial position of the at least one gear relative to the opening of the housing.
