摘要： The present invention provides a composite static rotary table and a method for protecting a composite static rotary table. The composite static rotary table comprises: a housing body provided with a mounting space; a rotary table body driven by a connecting mandrel to rotate; a base, the connecting mandrel being arranged through the base; an air stopping film arranged between the rotary table body and the base; and an auxiliary supporting assembly fixedly arranged in the mounting space and configured for assisting the rotary table body to be levitated relative to the base. The present invention is intended to solve the problem of ensuring the stable non-contact rotation of the rotary body of the rotary table relative to the base, while improving the bearing capacity of the rotary table.

摘要： A rotating assembly adapted for use in turbines and pumps is provided. The rotating assembly includes a shroud that rotates around a central axis and a disk seated in a recess in the shroud so that the disk rotates with the shroud, the disk being oriented perpendicular to the central axis. The rotating assembly also includes a stationary element in which at least one surface of the disk contacts a fluid so that when the fluid flows under pressure, the surface of the disk resists the generation of drag between the surface and the stationary element of the rotating assembly. A shroud is provided that includes a circular recess with a cavity on an outer perimeter extending away from the fixed assembly. A method of manufacturing a rotating assembly is provided.

摘要： A turbine-generator device for use in electricity generation using heat from industrial processes, renewable energy sources and other sources. The generator may be cooled by introducing into the gap between the rotor and stator liquid that is vaporized or atomized prior to introduction, which liquid is condensed from gases exhausted from the turbine. The turbine has a universal design and so may be relatively easily modified for use in connection with generators having a rated power output in the range of 50 KW to 5 MW. Such modifications are achieved, in part, through use of a modular turbine cartridge built up of discrete rotor and stator plates sized for the desired application with turbine brush seals chosen to accommodate radial rotor movements from the supported generator. The cartridge may be installed and removed from the turbine relatively easily for maintenance or rebuilding. The rotor housing is designed to be relatively easily machined to dimensions that meet desired operating parameters.

摘要： Thus, if a shock or other disturbance to a disc stack spindle bearing assembly occurs that tilts the bearing assembly, the resulting motion is both a tilting, and a motion which is axial. If a shock axially moves the hub assembly, only an axial motion occurs. Thus the system has a non-linear behavior. Pursuant to this invention, when a tilting disturbance occurs, and some of it is dissipated in a net axial movement at a different frequency, energy is subtracted out of the system with motion that is not linearly related to the disturbance that created it.
摘要翻译：因此，如果发生对盘式主轴轴承组件的冲击或其它干扰，从而使轴承组件倾斜，则所产生的运动既是倾斜又是轴向的运动。如果冲击轴向移动轮毂组件，则仅发生轴向运动。因此，系统具有非线性行为。根据本发明，当发生倾斜扰动并且其中一些在不同频率的净轴向运动中消散时，能量与系统中的运动无关，该运动与产生它的扰动不成线性关系。
