Title:
A GEAR HOUSING FOR A PLANETARY GEAR DEVICE THAT STRUCTURALLY ISOLATES AN INNER GEAR
Document Type and Number:
WIPO Patent Application WO/2021/024954
Kind Code:
A1
Abstract:
[Technical Problem] To provide separate structural units for an inner gear and a housing, that suppress transmission of vibration from a planetary gear mechanism and suppress noise produced by a planetary gear device. [Solution to Problem] Separate structural units for an inner gear and a housing comprise: an inner gear where first raised portions that extends from one side to the other side in the axial direction is formed on the outer peripheral surface; and a housing where a second raised portion that extends from one side to the other side in the axial direction is formed on the inner peripheral surface, and which contains an inner gear in a state wherein there is a gap from the inner peripheral surface. The movement of the inner gear within the interior of the housing is limited through linear contact of the first raised portion and the second raised portion.
