摘要： The pump (10) has a wave spring (52) acting between a pump housing (12) and the axially slidable outer race (42) of one roller bearing (36) for preloading the other bearing (34) with a selected preload force maintained on the other bearing to maximize bearing life and concentric rotation of a shaft (14) over all operating conditions of the pump. The shaft is rotatably supported on an axis (16) extending through the housing. A drive gear (18) is mounted on the shaft adjacent the drive end (20) of the housing. A fluid impeller (22) is provided at the opposite impeller end (24) of the housing. The axially spaced roller bearings (34,36) support the shaft in the housing. Each bearing has an inner race (40,44) fixed on the shaft, and an outer race (38,42) mounted in the housing. The outer race (38) of one bearing (34) is fixed in the housing to transmit major thrust forces from the shaft to the housing. The outer race (42) of the other bearing (36) is axially slidable in the housing to transmit minor thrust forces to the housing.

摘要： Since disruptive forces can be continuously exerted upon a rotor during a pulsatile flow through a pump with a magnetically mounted rotor (permanent magnets and addition control current coils), it is necessary to adjust position i.e. modify axial rotor position very quickly. The control current should only result in small amounts of losses. According to the invention, the current is pulse-width modulated by the control current coils by means of a set value predetermined by a controller which is arranged downstream from a position sensing system. If the set value is high, it is switched to a higher voltage level and the real value of the position sensing system is stored for a defined period of time, respectively beginning with the switching flank of the control current, and the position sensing system is disconnected during said period of time.

摘要： A lubrication system for equipment (e.g. centrifugal pump) employing a rotating shaft and corresponding support bearings is disclosed. The lubrication system includes a lubricant dispenser having a plurality of blades or dispensing members pivotally attached thereto, the dispenser affixed to the shaft for rotation therewith. Centrifugal force created by rotation of the shaft to which the dispensing blades are attached causes the blades to extend radially outward from the shaft center during operation so as to dispense the lubricant throughout a lubricating or misting chamber in order to lubricate the adjacent bearings. The system is also advantageous in that the blades are permitted to pivot or flap downward toward the shaft in either direction so that the dispenser may be more easily inserted into the misting chamber during manufacturing of the device or replacement of the lubricating system. In such a manner, a lubricant dispenser is provided that has an operating outer diameter that slices cleanly through the lubricating fluid to avoid excessive splashing and spraying of the fluid. This also allows the lubricant fluid level in the misting chamber to be lowered if desired so as to reduce heat generation during operation without overly splashing or spraying lubricant.
摘要翻译：公开了一种使用旋转轴和对应的支撑轴承的设备（例如离心泵）的润滑系统。润滑系统包括具有多个叶片或枢转地附接到其上的分配构件的润滑剂分配器，分配器固定到轴上以与其一起旋转。通过旋转分配叶片的轴产生的离心力使得叶片在操作期间从轴心径向向外延伸，以便在整个润滑或雾化室中分配润滑剂以润滑相邻的轴承。该系统的优点还在于允许叶片在任一方向上朝向轴转动或向下转动叶片，使得在制造装置或更换润滑系统期间，分配器可以更容易地插入雾化室中。以这种方式，提供润滑剂分配器，其具有通过润滑流体清洁地切割的操作外径，以避免流体的过度飞溅和喷射。如果需要，也可以使雾化室中的润滑剂液面降低，以减少操作过程中的发热，而不会过度喷溅或喷涂润滑剂。

摘要： A steam turbine rotor is constructed from a first forging of a first alloy, and a second forging of a second alloy different than the first alloy. For example, one of the alloys is suitable for use in a high temperature environment and the other in a low temperature environment. The forging ends are contoured so as to provide central portions, which may be disc-shaped, and the contoured portions may be in the shape of truncated cones. A first weld, such as a root weld formed by inertia, friction, or electroslag welding, joins the central portions, and the contoured portions are joined by a second weld different than the first weld, such as a submerged arc weld. This allows the rotor forgings to be joined in relatively inexpensive horizontal facilities, and reduces the demands on the welding technology required to obtain a sound root weld.
