RADIAL ROLLER BEARING, ROTARY MACHINE INCLUDING RADIAL ROLLER BEARING, AND METHOD FOR DESIGNING RADIAL ROLLER BEARING |
摘要 |
The properties of a lubricating oil are utilized to avoid excessive quality in terms of the circularity of roller members while reducing the noise from a radial roller bearing alone during rotation and thereby reducing the noise from a rotary machine. A radial roller bearing includes an outer ring member (30A), a plurality of roller members (30B), and a retainer, and a lubricating oil (0) is supplied between the outer ring member (30A) or a rotating shaft and the roller members (30B). The circularity (ΔR) of the roller members (30B) in a cross section perpendicular to a centerline (CL) thereof is set to be lower than or equal to the minimum oil film thickness (hmin) of an oil film formed by the lubricating oil (O). |

1. A radial roller bearing comprising:
an outer ring member; a plurality of roller members that roll on an inner surface of the outer ring member; and a retainer, a lubricating oil being supplied between the outer ring member or a rotating shaft and the roller members, wherein the circularity of the roller members in a cross section perpendicular to a centerline thereof is set to be lower than or equal to the minimum oil film thickness of an oil film formed by the lubricating oil. |
