Title:
MANUFACTURING METHOD OF STATIC PRESSURE GAS JOURNAL POROUS BEARING AND STATIC PRESSURE GAS JOURNAL POROUS BEARING
Document Type and Number:
Japanese Patent JP2023047636
Kind Code:
A
Abstract:
To provide a manufacturing method of a static pressure gas journal porous bearing which can fixedly position a porous member relative to a housing member, seal a gap between the housing member and the porous member, and secure a supply amount of a gas to a bearing gap formed between the porous member and a shaft with a simple structure, and to provide the static pressure gas journal porous bearing.SOLUTION: A bearing 100 includes: a cylindrical porous member 110; and a housing member 120 having a cylindrical part 121, into which the porous member 110 is inserted, and supports a radius load of a shaft S with a gas jetted from the porous member 110. A manufacturing method of the bearing 100 includes: a press-fitting step where a front end 113 of the porous member 110 is press-fitted into a front end insertion portion 121A of the cylindrical part 121; and a sealing step where a rear end insertion portion 121C of the cylindrical part 121, in which a rear end 114 of the porous member 110 is loosely fitted, is plastically deformed to form a protruding area 121C1 and deform the rear end 114 of the porous member 110.SELECTED DRAWING: Figure 2
