Title:
ROLLING DEVICE AND METHOD FOR MANUFACTURING ROLLING DEVICE
Document Type and Number:
WIPO Patent Application WO/2015/186336
Kind Code:
A1
Abstract:
A rolling device is provided with: an inner member having a raceway surface on an outer surface; an outer member which has a raceway surface opposed to the raceway surface of the inner member and which is disposed outside the inner member; and a rolling element disposed so as to be capable of rolling between both the raceway surfaces, wherein at least one of the inner member and the outer member has a space therein. A method for manufacturing a rolling device comprises manufacturing, using a 3D printer, a rolling device provided with: an inner member having a raceway surface on an outer surface; an outer member which has a raceway surface opposed to the raceway surface of the inner member and which is disposed outside the inner member; a rolling element disposed so as to be capable of rolling between both the raceway surfaces; and a space formed in at least one of the inner member and the outer member. This makes it possible to provide a conventionally unavailable rolling device having a structure enabling a significant weight reduction, and a method for manufacturing the rolling device.
