Title:
ECCENTRIC ROTATION DRIVE DEVICE
Document Type and Number:
WIPO Patent Application WO/2012/046444
Kind Code:
A1
Abstract:
[Problem] To provide an eccentric rotation drive device that is capable of performing appropriate lubrication and cooling by means of a processing liquid while suppressing damage to members and loss of energy resulting from friction. [Solution] The rotating shaft (13) of the eccentric rotation drive device (100) has therewithin a flow path (131) that causes the flow of a lubricating oil (F). The flow path (131) has: a thrust flow path (131a) that is formed along the axial direction; and a radial flow path (131b) that extends from the thrust flow path (131a) along the direction of the diameter of the rotating shaft (13). The end of the radial flow path (131b) is connected to a bearing (15). By means of this kind of flow path (131) configuration, it is possible to lead the lubricating oil (F) from the end (13b) of the rotating shaft (13) to the bearing (15) using the rotating movement of the rotating shaft (13).
