Title:
LINK-ACTUATING DEVICE
Document Type and Number:
WIPO Patent Application WO/2004/073935
Kind Code:
A1
Abstract:
In a link-actuating device, the outline of a link hub is expanded without expanding the outline of the entire device, and a drive mechanism, such as an actuator, is compactly provided. In a link-actuating device, end portion link members are rotatably connected to each of link hubs respectively arranged at the input side and the output side, the device has three sets of link mechanisms where the input side and output side end portion link members are rotatably connected to central link members, and the input side and output side link mechanisms are geometrically the same with respect to a cross section at the center portion of each link mechanism. Bearing outer rings are enclosed in each link hub and bearing inner rings are connected to the end portion link members, and as a result, bearing structures are installed in the link hubs.
