摘要： A bearing for supporting a rotating shaft receiving a transverse load, wherein the bearing supports the shaft along a load line and wherein the bearing is closest to the rotating shaft at a running line. The bearing includes a circumferential inner surface, and a lubricant bay defined in the inner surface. The lubricant bay is axially and circumferentially offset from the load line such that a resulting pressure pad of lubricant within the bay provides a hydrostatic force that forces the running line to a location substantially perpendicular to the load line. Load capabilities of a bearing according to the present disclosure, therefore, are substantially insensitive to shaft bending and do not deteriorate in response to the shaft bending.

摘要： The invention relates to a method for providing a roll (1) for a paper machine with sliding bearings, the roll comprising a stationary roll axle (3) and a tubular roll mantle (2) arranged to revolve around it. In the method, the roll mantle (2) is supported on the roll axle (3) by means of hydraulic sliding bearing members (4a, 4b, 5a, 5b; 25, 28; 40a, 40b) which are arranged to accomplish radial fitting with bearings of the roll mantle in the loading direction and in the lateral direction with respect to it, and the axial fitting with bearings of the roll mantle. The sliding bearing members are loaded by means of a hydraulic medium, the feed of which to the sliding bearing members is controlled by means of control valves (6; 30; 40). In the method relating to the invention, when loading (F) is applied to the sliding bearing member (4a, 4b) effective in the loading direction, the loading force applied to the sliding bearing member (4a, 4b) subject to an external load due to the loading is compensated for automatically, essentially immediately, without an external control instruction, by means of the movement of the control valve (6) stem (60) of the sliding bearing member (4a, 4b) subject to loading, the said control valve (6) bringing about a rapid increase in the pressure of the hydraulic medium in the sliding bearing member (4a, 4b) subject to the external load, at the same time as the pressure of the medium supplied to the sliding bearing member (5a, 5b) located radially on the opposite side of the roll axle (3) in the loading direction is adjusted to a certain minimum value, whereby the bearings of the roll mantle are rendered so as to be essentially without stroke. The invention also relates to a roll for a paper machine which is provided with sliding bearings.

摘要： Fluid thrust bearing containing moving magnet indicating instrument (10) includes a bobbin (12) and transparent lens (14) through which pointer (16) and dial (18) can be viewed. Pointer (16) is mounted to end of shaft (20) having axis of revolution (28) and attached to rotor (30) in bore (34). The rotor (30) is disposed in close-fitting walled cavity (26) so as to define a small substantially air excluded damping fluid filled gap (32) therebetween. Shown near detail arrows (1A) are excess fluid containing reservoir (33) formed by raised torroidal ridges (36, 38). Indicator (10) contains two pairs of field coils (22.1, 22.2, 24.1, 24.2). Adhesion and cohesion help maintain the rotor (30) in cavity (26). The substantial air exclusion helps prevent rotor (30) from moving axially out of cavity (26). A method of assembling to create such conditions therein is also set forth.

摘要： The invention relates to a regulator for adjusting the medium flow from a medium supply to at least one hydrostatic or aerostatic pocket of a bearing arrangement, a threaded spindle nut or a guide. Said regulator comprises a housing and pressure chambers which are separated by a control element that can be displaced by the force of a spring element. A first pressure chamber is subjected to a first pressure level (p1) and is directly connected to the medium supply. A second pressure chamber is subjected to a second, lower pressure level (p2) and is connected to the medium supply via a first medium resistance element. A third pressure chamber is subjected to a third pressure level (p3) which corresponds to the hydrostatic or aerostatic pocket, said third chamber being connected to the hydrostatic or aerostatic pocket. The regulator (1) is characterized in that the housing (7) has a support surface (19) comprising a passage orifice (30; 46) for the medium flow. When the regulator (1) is mounted, it rests on a counter surface (23; 23') located on the bearing arrangement, the threaded spindle nut or the guide so that a direct medium communication (3; 3') between the regulator (1) and the pocket and/or the medium supply is achieved.

摘要： A damping arrangement for axial vibrations in a turbomachine shaft (10) comprises at least one circumferentially extending annular damping chambers (34 and 35) open towards a shaft thrust face (19A and 19B) of radially extending collar (20) and to which gas is supplied alternately by gas flow controllers (42A and 42B). Each controller contains fluidic devices switched by sensing pressures in radially displaced pressure sensing chambers (51, 53), or even the same chambers, as such pressures are modulated by the variations in shaft and collar position, to divert the gas from source (40). The diversion of gas flow is arranged to cause pressure fluctuations, which exert axial thrust on the thrust faces, advanced in phase to approach of the shaft so as to damp the vibration. The fluidic devices may be implemented by flow amplifiers (47A, 47B) or fluid logic flip flop (61) (Figure 2) and may be multistage devices to increase gain, all of which may be formed without moving parts and embedded in the housing. Flow diversion may be effected by other forms of sensing, such as leakage from a nozzle facing the shaft. The arrangement may be combined with, or serve as, a gas seal or be part of a bearing arrangement.

摘要： A hollow poriton is defined in the axis of an inner shaft (2) to form a center oil feed passage (3), and a plurality of oil feed ports (4) penetrating through an outer peripheral surface of the inner shaft (2) from this center oil feed passage (3) are aligned radially within the range (L) of a bearing surface of the inner shaft (2). An oil groove (5) in an axial direction, inclusive of an opening (4a) of each oil feed hole (4) on the inner shaft surface side, is disposed on the inner shaft outer peripheral surface. In this way, a reversing bearing device for double reversing propeller for driving the inner shaft (2) and the outer shaft (2) in mutually opposite directions is constituted. A plurality of concavoconvex portions are formed on the inner peripheral surface of the reversing bearing in place of the oil groove in the axial direction of the bearing, and complete circle portions are disposed at both end portions of the concavoconvex portions in the axial direction so as to constitute a reversing bearing device for double reversing propeller. In these bearing devices, a sufficient oil film is formed on the bearing face of the reversing bearing in the rotation range where the inner shaft and the outer shaft rotate in mutually opposite directions at a substantially equal speed, and a satisfactory bearing function can be obtained.
