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).

摘要： An electric compressor includes a motor, a scroll compression mechanism, a housing, a circuit unit, a circuit housing housing the circuit unit and integrated with the housing. The electric compressor includes a heat sink provided on a circuit unit side of a partition wall so as to project to be brought into contact with a semiconductor element of a power substrate, facing the partition wall that erects along a vertical direction to separate the inside of the housing from the circuit housing. The heat sink has a lower surface and an upper surface formed into a cylindrical shape so that width of an upper end portion and a lower end portion of the heat sink gradually decreases to reach a tip portion.
