摘要： A circumferential seal assembly capable of separating a gas into two separate flow paths before communication onto a pair of seal rings is presented. The seal assembly includes an annular seal housing, a pair of annular seal rings, a rotatable runner, and a plurality of groove structures. The seal housing is interposed between a pair of low pressure compartments. The seal rings are separately disposed within the seal housing and separately disposed around the rotatable runner. The groove structures are disposed along an outer circumferential surface of the rotatable runner. The gas is communicable onto the groove structures. Each groove structure bifurcates the gas before communication onto the seal rings. Flow within each groove structure may be further separable before the gas is communicated onto the seal rings. The gas forms a thin-film layer between the rotatable runner and each seal ring.
摘要翻译：提出了一种圆周密封组件，其能够在连接到一对密封环上之前将气体分离成两个单独的流动路径。密封组件包括环形密封壳体，一对环形密封环，可旋转流道和多个凹槽结构。密封壳体介于一对低压室之间。密封环分别设置在密封壳体内并且分开设置在可旋转的流道的周围。槽结构沿着可旋转的流道的外圆周表面设置。气体可以连通到凹槽结构上。每个沟槽结构在通气之前将气体分叉到密封环上。在气体连通到密封环之前，每个凹槽结构内的流动可以进一步分离。气体在可旋转的流道和每个密封环之间形成薄膜层。

摘要： A foil bearing includes an outer member (11), and a plurality of foils (13) that are mounted to an inner circumferential surface (11a) of the outer member (11) and directly face the inner circumferential surface (11a) of the outer member (11) in a radial direction without interposition of another member (such as back foils). The foils (13) each include: holding portions (13a, 13b) that are formed at both circumferential ends and held while in contact with the outer member (11) ; and a body portion (13c) that is formed circumferentially between the holding portions (13a, 13b) and has a bearing surface (A). At least an end portion on one side in a circumferential direction of the body portion (13c) is raised radially inward with respect to the inner circumferential surface (11a) of the outer member (11).

摘要： A method of and a device for protecting an electric motor (4) in a pod unit (1) for propulsion of marine vessels against shaft bending shocks when the blades (2) of the pod propeller hit ice blocks or other hard objects, said motor (4) having a drive shaft (3), a rotor (41) and a stator (42), said shocks tending to momentarily bend the drive shaft (3) to such an extent that the rotor (41) will come into contact with the stator (42). In accordance with the present invention, the rotor (41) is prevented from coming in detrimental contact with the stator (42) by providing at least two members (61, 62), which together form a radial plain bearing (6) having mating arcuate bearing surfaces (611 and 621, respectively), which during normal operation of the motor (4) are spaced from one another by a gap and come in contact with one another only at extreme loads with short durations. One of the members (61, 62) is an inner member (61) having a circular circumference that constitutes one (611) of the bearing surfaces (611, 621). The arcuate bearing surface (611) of the inner member (61) is coaxial with the rotor (41) and rotary therewith, and at least one of the other members is an outer member (62), which fixed in relation to the stator (42) and has its arcuate bearing surface (621) coaxial there with.

The seal housing is interposed between a pair of compartments. The seal rings are separately disposed within the seal housing and separately disposed around the rotatable runner. The groove structures are disposed along an outer annular surface of the rotatable runner. A gas is communicable onto the groove structures. Each groove structure includes at least two hydrodynamic grooves that separate and communicate the gas onto the seal rings. Each groove includes steps whereby the depth of at least one adjoining step decreases in the direction opposite to rotation with or without the depth of another adjoining steps increasing in the direction opposite to rotation. Each groove is also tapered widthwise.

摘要： An air bearing for calibrating a force measurement device comprises an inner wall, an outer wall, an upper wall, a lower wall, an internal chamber, an object retention opening, and a plurality of air outlets. The inner wall and outer wall each have a cylindrical shape with the outer wall being concentric with the inner wall. The upper wall and lower wall each have an annular shape and are attached to the inner wall and the outer wall. The internal chamber is formed by inner surfaces of the four walls, and is configured to retain compressed air. The object retention opening is formed by an outer surface of the inner wall and is configured to receive and retain an object. The air outlets are positioned along the inner wall and are configured to allow compressed air to flow from the internal chamber to the object retention opening.
