Title:
ECCENTRIC ROTATION DRIVE DEVICE
Document Type and Number:
WIPO Patent Application WO/2012/046405
Kind Code:
A1
Abstract:
[Problem] To provide an eccentric rotation drive device that can avoid enlargement of the eccentric rotation drive device and that is capable of suppressing power consumption. [Solution] The eccentric rotation drive device (100) is provided with: a canned motor (5) having a rotating shaft (13); and a lubricating oil (F) can be housed in a casing (10) using a can (16); thus, it is possible to supply the lubricating oil (F) to each member within the casing (10). As a result, there is no need to provide a separate lubricating liquid supply device and it is possible to perform lubrication and cooling of a rotation bearing (15) and the like, and so it is possible to avoid the eccentric rotation drive device (100) being enlarged. Also, as a suitable quantity of lubricating oil (F) that does not fill the casing (10) is housed, resistance to the rotation of a rotor (11) does not become large, and so it is possible to suppress power consumption.
