摘要: A foil bearing unit includes: a first foil holder formed of a single component; a radial bearing foil mounted to an inner peripheral surface of the first foil holder; a thrust bearing foil mounted to an end surface of the first foil holder; and an inner member including: a shaft portion; and a flange portion projecting radially outward from the shaft portion. The inner member is supported in a radial direction by a fluid pressure that is generated in a radial bearing gap between a bearing surface of the radial bearing foil and an outer peripheral surface of the shaft portion, and the inner member is further supported in a thrust direction by a fluid pressure that is generated in a thrust bearing gap between a bearing surface of the thrust bearing foil and one end surface of the flange portion.

摘要: A foil bearing includes an outer member (11), and a plurality of foils (13) that are mounted to an inner circumferential surface (11a) of the outer member (11) and directly face the inner circumferential surface (11a) of the outer member (11) in a radial direction without interposition of another member (such as back foils). The foils (13) each include: holding portions (13a, 13b) that are formed at both circumferential ends and held while in contact with the outer member (11); and a body portion (13c) that is formed circumferentially between the holding portions (13a, 13b) and has a bearing surface (A). At least an end portion on one side in a circumferential direction of the body portion (13c) is raised radially inward with respect to the inner circumferential surface (11a) of the outer member (11).

摘要: The present invention aims to shorten a drying time for time for drying a coiled electrode. To this end, a drying device for drying the coiled electrode wound on a winding core includes a heating unit for heating the coiled electrode from a winding core side. Since this enables heat to be transferred from a core part toward a surface of the coiled electrode, tiny spaces can be generated between layers of an electrode and moisture can be evaporated from these spaces. Thus, moisture of the core part side, which has been difficult to evaporate, can be reliably evaporated and a drying time for the coiled electrode can be shortened.
