    摘要： A food cutter assembly can include a spindle body defining an interior passage for receiving a food product. The food cutter assembly can also include a thrust disc connected to the spindle body. The thrust disc can include opposing surfaces extending radially from the rotational axis of the spindle body and a circumferential surface between the opposing surfaces. A cutting tool can be connected to an end of the spindle body for cutting the food product. The food cutter assembly can also include a housing for rotationally mounting the spindle body, where the housing includes a radial bearing to be positioned proximate to the thrust disc. The spindle body and the housing can define fluid passages extending from a port in the housing through the radial bearing to the spindle body and across the opposing surfaces and the circumferential surface to the spindle body.

    摘要： A fluid bearing for use in turbomachinery including at least one bearing pad configured to be arranged about a rotating member of the turbomachinery. Each bearing pad includes an internal cooling opening defined in the bearing pad and an internal channel network defined in the bearing pad with at least one channel node in fluid communication with the internal cooling opening and at least two passageways in fluid communication with and extending from the channel node through the bearing pad. At least one of the passageways extends to an exterior surface of the bearing pad to define at least one cooling discharge opening.

    摘要： A micro-machine powered by an electric motor and/or a gas turbine drive and capable of rotation speeds to 1,500,000 rpm is disclosed. The micro-machine may include a rotating spindle which is constructed, balanced and arranged to provide a tool holder function and may incorporate a portion of the drive system. The other portion of the drive system is incorporated in a machine housing. The housing locates and supports at least one foil thrust bearing and at least one foil journal bearing to support the spindle. The housing and the bearings may be split into at least two parts and reassembled and the housing incorporates a gas reservoir and gas distribution channels for forced gas cooling of the bearings. In one embodiment of a foil journal bearing, a plurality of overlapping top foil segments supported by individual bump foil segments consisting of generally uniformly-spaced ridges and flats are secured within a housing. The bearing may be split and the bump foil stiffness may be adjusted by modifying the geometry, number and/or arrangement of the bump foils. In one embodiment of a foil thrust bearing a plurality of top foil segments are supported by coextensive individual bump foil segments including ridges and flats and secured on a thrust plate. The bearing may be split. The bump foil may be divided into a series of tabs separated by slits, each of the tabs having a number of ridges separated by flats. The ridges and flats on adjacent tabs may be arranged to reduce bearing heating. Provision may be made for cooling of the bearing by forced radial gas inflow.
