摘要： Bearing structural member, a support, a joint assembly and a tube section assembly, wherein the maximum counter force provided by the bearing structural member under an external load is an own designed threshold value, namely when the external load is greater than the designed threshold value of the bearing structural member, the bearing structural member deforms, and provides a counter force equal to the designed threshold value; the support includes at least one bearing structural member; and the joint assembly and the tube section assembly are both equipped with the support. When the external load is not high and is less than the designed threshold value, the bearing structural member may effectively suppress the deformation just like a rigid structural member; when the external load exceeds the designed threshold value, the bearing structural member may deform, and provide a stable counter supporting force less than the external load. The bearing structural member may be applied to the support, the joint assembly and the tube section assembly, plays a role in protecting the structures or key structural components, and may be widely applied to the fields of design of bridges, design of building structures, design of tunnels and the like.

摘要： There is provided an axial bearing load distribution system (20) for a gas turbine engine of the type having a low pressure rotor (21) supported by axial bearings (22,24). The system comprises a line (30) having an inlet end positioned in a highpressure compressor gas path downstream of any compressor stage provided with a variable geometry. The line (30) is adapted to sense static pressure in the highpressure compressor gas path. The line (30) has an outlet end producing the static pressure. An air-tight pressure actuator (26) is operatively connected to the outlet end and to one of the axial bearings (24) to exert a force on the axial bearing (24) proportionally to a pressure of the outlet end.

摘要： Construction of a rotation support device for a pinion shaft is achieved that, together with being able to sufficiently maintain axial rigidity of a rolling bearing on the side opposite from the pinion gear side, it is able to sufficiently reduce the dynamic torque during operation and the starting torque at the start of operation. Together with using a single-row angular contact ball bearing 14a as the rolling bearing on the side opposite from the pinion gear side, the ratio of the radius of curvature Ro of the outer raceway 22a and the diameter Bd of the balls 25a (Ro/Bd) is regulated within the range 0.52

摘要： A tilting pad thrust bearing (10) and a tilting pad thrust bearing assembly are provided. The tilting pad thrust bearing is configured such that when a load is concentrated on only a portion of a thrust bearing because of eccentricity or inclination of a rotating shaft, associated tilting pads are tilted so that the load can be dispersed to the other tilting pads to which comparatively small load is applied, whereby the tilting pads to which the concentrated load is applied can be prevented from being damaged. Furthermore, the tilting pads can be fixed by oil supply nozzles without using a separate fastening member, whereby the size of the tilting pad thrust bearing can be markedly reduced. The tilting pads and a plate have improved structures so that the time and cost required to manufacture the tilting pad thrust bearing or tilting pad thrust bearing assembly can be reduced.
摘要翻译：提供倾斜垫推力轴承（10）和倾斜垫推力轴承组件。倾斜垫推力轴承构造成使得当负载集中在推力轴承的一部分上时，由于旋转轴的偏心或倾斜，相关联的倾斜垫片被倾斜，使得负载能够分散到另一个倾斜垫片施加相对较小的载荷，由此可以防止施加集中载荷的倾斜垫被损坏。此外，倾斜垫可以通过供油喷嘴固定而不使用单独的紧固构件，由此可以显着地减小倾斜垫推力轴承的尺寸。倾斜垫片和板材具有改进的结构，从而可以减少制造倾斜垫推力轴承或倾斜垫推力轴承组件所需的时间和成本。

摘要： In order to accommodate loading in a number of situations such as with regard to thrusts in a gas turbine engine it is known to provide thrust bearings. These thrust bearings can be large and may be difficult to accommodate. By providing a duplex or multiplex thrust bearing which may be of increased axial length but reduced radial width easier accommodation may be achieved. By providing a thrust element 27 which compromises a balance beam from which extend elastic hinges to a mounting to a fixed bearing frame and ends of bearing races 21, 22 an appropriate thrust response can be achieved dependent upon bearing loads presented through bearing elements 23, 24. By rotation of the balance beam and flexing of the elastic hinges 30, 31, 32 an appropriate bearing load share is achieved.

摘要： Das Axialgleitlager (1) umfaßt mehrere Lagerbuchsen (2-4) und Stützbuchsen (5-7) mit axialen Distanzstutzen (8-10, 14-16) und Radialbunden (11-13, 18-20). In Belastungsrichtung (F) sind jeweils hintereinander angeordnete und mit Öl beaufschlagbare Druckflächenpaare (25-27) vorgesehen, die jeweils zwei sich frontal gegenüberliegende Druckflächen (23, 24) aufweisen. Die Dicke der Radialbunde (11-13) der Lagerbuchsen (2-4) ist kleiner als die Dicke der Radialbunde (18-20) der Stützbuchsen (5-7) bemessen. Die Wanddicke der Distanzstutzen (8-10) der Lagerbuchsen (2-4) nimmt von Lagerbuchse (2) zu Lagerbuchse (4) zu. Die Wanddicke der Distanzstutzen (14-16) der Stützbuchsen (5-7) nimmt in derselben Richtung von Stützbuchse (5) zu Stützbuchse (7) ab. Ölführungsbohrungen (34) in den Radialbunden (18-20) der Stützbuchsen (5-7) sichern ein übereinstimmendes Temperaturniveau der Lagerbuchsen (2-4) und der Stützbuchsen (5-7).
