The speed reduction device includes a driving device, a first stage speed reduction assembly and a second speed reduction assembly. The first speed reduction assembly includes a power gear and a face gear. The second speed reduction assembly includes a sun gear that rotates coaxially with the face gear, a planet gear set driven to rotate by the sun gear, a fixed gear, an output gear for outputting power and a fixed shaft. The speed reduction device uses the first speed reduction assembly and the second speed reduction assembly for power transmission and is compact in structure and has a high single stage transmission ratio.

Abstract: A gearbox includes two axially spaced epicyclic gear trains, each having a sun gear, axially spaced planet gears carried by a planet carrier, and a ring gear fixed to the gear box. One of the planet gears engages with the fixed ring gear, and another of the planet gears engages with an output ring gear. The sun gears of the two gear trains are mounted on a single shaft. The planet carriers of the two gear trains are mounted on a shaft so that they can freely rotate but have limited axial motion along the shaft. The two output ring gears are helical gears of opposite handedness.

Abstract: The present disclosure relates to an epicyclic gear train comprising a driving pinion (3), driving a plurality of planetary gears (7). Each planetary gear rotates around a planetary axis (23), which has first (9) and a second (11) interconnected gears with different numbers of teeth. The first gear (9) meshes with a first ring gear (19), which is stationary, and the second gear (11) meshes with a second ring gear (25) which is thereby made to rotate about a central axis (21) of the planetary gearing. An adjusting arrangement is arranged to alter the distance between the central axis (21) and each planetary axis (23), such that gearing backlash can be substantially eliminated.

Abstract: An improved support ring (50) is disclosed for supporting a plurality of planetary gear sets (20) which are driven by a centrally disposed input shaft (12) having a sun gear (16) attached thereto in which the planetary gear sets are subject to radially inward loads. The support ring (50) includes an inner ring (52) and an outer ring (57). The inner ring (52) has a bore (54) which is disposed around the input shaft (12) and an outside surface (56) and the outer ring (57) has a bore (58) with a diameter greater than the diameter of the outside surface of the inner ring. The outside surface (60) of the outer ring rotatably supports the planetary gear sets (20). Preferably, the outer ring (57) has a spring rate which is less than the inner ring (52) to readily permit absorption of radial loads when the outer ring does not contact the inner ring. A retaining ring (62) may be provided to maintain a fixed axial relationship between the inner (52) and outer rings (57).

Abstract: A ride-on vehicle, such as for a child, includes a vehicle body and one or more wheels that support the vehicle body relative to a surface. At least one of the wheels includes a hub motor arrangement that provides a drive torque for propelling the vehicle. The hub motor arrangement includes a housing defining an interior space. An axle or other mounting element(s) define an axis of rotation of the housing. Preferably, the axle or other mounting element(s) do not pass completely through the housing. A motor drives the housing through a transmission. Preferably, the motor is a standard, compact motor that is positioned on the axis of rotation and can be laterally offset from a central plane of the housing. In some embodiments, a traction element is carried directly by the housing.
