摘要： A screw compressor utilizing radial and axial or thrust bearings to maintain the position of the rotors radially and axially and utilizing a damping fluid to dampen rotor vibrations. The damping fluid may conveniently be provided in the form of lubricant that is already used in the compressor to seal the clearances between the rotors and between the rotors and the cylinder during compression. The damping fluid is included in a squeeze film damper, arranged in a parallel arrangement with the radial or thrust bearings, which provides viscous damping to the rotor. The introduction of additional viscous damping such as may be provided by squeeze film dampers may result in significant reduction of compressor vibration regardless of the source of vibration.
摘要翻译：螺旋压缩机利用径向和轴向或推力轴承来径向和轴向保持转子的位置，并利用阻尼流体来抑制转子振动。阻尼流体可方便地以已经用于压缩机中的润滑剂的形式提供，以在压缩期间密封转子之间以及转子与气缸之间的间隙。阻尼流体包含在挤压膜阻尼器中，与径向或推力轴承平行排列，为转子提供粘性阻尼。附加的粘滞阻尼的引入可以由挤压膜阻尼器提供，无论振动源如何，都可以导致压缩机振动的显着减小。

摘要： The invention relates to a method for monitoring the operation of a plain bearing, whereby a lubricant channel (15), for a bearing segment (11), which is provided for provision of, for example, lifting oil, is used during hydrodynamic operation of the plain bearing for the taking of a sample for a temperature monitoring. A switching device (19) opens a flow path from the lubricant channel (15) into a drain channel (23) to initiate the measuring operation, such that lubricant from the lubricating film (13) flows through the lubricant channel, the temperature of which is determined by a temperature probe (16, 18).

摘要： The invention concerns a bearing control system for a roll with hydrostatic bearings, which roll is mounted from its axle (3) on a bearing block or on an equivalent frame member by means of a number of hydraulically loaded hydrostatic bearing elements (10, 20, 30). At least one bearing element is a so-called principal bearing element (10), which acts in the principal loading direction, and one bearing element is a so-called backup bearing element (20), which acts in the direction opposite to the principal loading direction. The bearing elements are provided with bearing shoes positioned freely around the neck of the roll axle (3) in order to support said axle (3) and, thus, the roll revolvingly in relation to the frame member, such as a bearing block. The control system has been arranged preferably to feed the pressures of the hydraulic pressure medium passing to the hydrostatic bearing elements (10, 20, 30) so that the roll can be displaced in the principal loading direction (A-A), for example in the direction of the nip plane, by displacing the axle (3) by means of said bearing elements (10, 20, 30).

摘要： A novel means for the design of the pockets of a hydrostatic spindle and the flow supply, collection, and pocket (15B) injection means to allow for very high speed rotation with a minimum of heat generation, and maximum load capacity; furthermore the concept of self-compensation is used to make the design insensitive to contaminants and thereby allow for the use of water based hydrostatic fluids, whereas the design of the compensator region is also advanced to facilitate high speed use. Accordingly, the present invention allows designers to increase the allowable speed and accuracy of rotary motion hydrostatic bearings. Design methodologies are presented for designing self-compensating hydrostatic bearing spindle pockets and compensators to minimize the effects variation in stiffness with angular position, cavitation in bearing pockets, and turbulent shear power generation. Although it may seem that these are unrelated effects, the design solutions required substantially overlap and are thus presented together here. The primary issue in all of the design advancements is that the flow must be kept from separating, which will induce cavitation. This will result in wear and erosion of the bearing surfaces which will lead to bearing failure. Cavitation is prevented by the use of gently changing shapes, and the introduction of pressure at locations in the bearing where left to itself, the flow would separate and create a low pressure and create a low pressure cavitating region.

摘要： @ A hydrostatic journal bearing with two opposed bearing pads in which the typical tendency of the bearing clearance to change due to variation in the viscosity of the operating fluid, brought about by temperature change, is counteracted by causing the sum of the pressures (p 1 , P2 ) existing at the two pads (22, 23) to be held to a constant value. Typically this value is equal to that of the pressure (p 2 ) of the supply (27). The supply may be connected to the two pads by way of separate adding valves (40, 29) which may be arranged in parallel with restrictors (41, 28) which are themselves in series with the pressure source (27). Such restrictors may be fixed but may also with advantage be controlled by reference to the pressure existing at their respective pads (22. 23), provided they respond symmetrically to variations of fluid temperature and so give rise to no change in the relative position of the bearing members in response to such variations. Alternatively only a single adding valve may be used, which advantageously may provide a third, reference output pressure (p o ) supplied to the pads (22, 23) in parallel with their respective basic pressure supplies (p 1 , p 2 ).
摘要翻译：具有两个相对轴承垫的静压轴颈轴承，其中由于温度变化而导致的轴承间隙由于工作流体的粘度变化而发生变化的典型趋势通过使压力（p1，p2）的总和）存在于两个焊盘（22,23）处以保持恒定值。通常该值等于电源（27）的压力（p2）值。可以通过单独的添加阀（40,29）将供应源连接到两个焊盘，所述阀可以与本体与压力源（27）串联的限位器（41,42）平行布置。这样的限制器可以是固定的，但是也可以通过参考在它们各自的垫（22,23）处存在的压力来控制，只要它们对称地响应于流体温度的变化，并且因此不会改变相对位置响应于这种变化。或者，可以仅使用单个添加阀，其有利地可以提供与它们各自的基本压力供应（p1，p2）并联的衬垫（22,23）的第三参考输出压力（p0）。
