  • Publication number: 20200355176
    Abstract: A linear compressor includes a housing defining a sump for collecting a lubricant and a suction inlet for receiving a flow of refrigerant into the housing. A pump circulates the lubricant within the housing, e.g., for lubricating a piston that is movable along the axial direction to compress the flow of refrigerant. A flex mount is coupled to the piston and defines a channel inlet for receiving the flow of refrigerant. A splash shield is positioned within the housing between the channel inlet and a pump inlet along the vertical direction, e.g., to prevent oil entrainment into the flow of refrigerant.

    Abstract: A tilting pad journal bearing is arranged such that a circumferential relative position of an opening portion of an oil feeding hole to supply lubricant oil to a sliding portion of a bearing pad with respect to the bearing pad differs depending on the position of each bearing pad. For a bearing pad under a rotary shaft which supports the load of the rotary shaft, the circumferential position of an opening portion of an oil feeding hole with respect to the bearing pad is set toward an upstream side of a space between pads in a rotating direction of the rotary shaft. For a bearing pad above the rotary shaft, the circumferential position of an opening portion of an oil feeding hole with respect to the bearing pad is set toward a downstream side of a space between pads in the rotating direction of the rotary shaft.

    Abstract: An improved roller bearing assembly is disclosed. The improved roller bearing assembly incorporates roller elements having an axially connected cage or spacer connection point which allows the use of a flexible corded or connected spacer assembly. This allows the use of less cage or spacer assembly material than traditional bearing cage designs. It also allows for easier assembly and disassembly of the roller bearing assembly and reduces parasitic drag or friction by reducing the size and cross-section of the cage or spacer assembly. Alternate embodiments incorporating magnets for electromagnetic interaction, vanes for fluid interaction, and offset configuration for the cage elements are also disclosed.
