Title:
SEALING STRUCTURE AND CONVEYANCE ROBOT PROVIDED WITH SAME
Document Type and Number:
WIPO Patent Application WO/2014/102887
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a sealing structure for a rotating section, the structure using a magnetic fluid seal. With the sealing structure, stable sealing performance is obtained even if a deformation such as bending of a supporting shaft occurs in the rotating section. A sealing structure (30) for sealing the connection (20) between a first arm (11) and a second arm (12) that is connected to the first arm (11) via a rotation shaft (23), wherein the sealing structure (30) comprises a magnetic sealing section (50) that uses a magnetic fluid and a bellows sealing section (40) configured from a bellows (41). With said sealing structure (30), because the sealing structure (30) for the connection (20) between the two rotatably connected members (11, 12) is configured using a magnetic sealing section (50) and a bellows (41), bending of the rotation shaft (23) of the connection (20) can be absorbed by the bellows (41) while rotatability is maintained, and a stable sealed state is secured.
