摘要： A gap setting apparatus incorporates an air gage to measure the pressure drop (and indirectly the flow rate) of air through a gap of a hydrodynamic bearing, while facing sections of the bearing are moved closer together. The measured pressure drop can be correlated to the actual bearing gap and monitored to determine when the proper gap has been achieved. More particularly, the inner and outer elements of the bearing are clamped in separate carriers and are held in place. The carriers are then moved toward one another so that the inner or shaft portion of the bearing slides into the outer or sleeve portion of the bearing. To accurately set the gap between the two, an air hose with an air gage attached to it is attached to one end of the bearing gap; air is pumped through the bearing gap, exiting through the opposite end of the gap, By testing a set of reference motor parts, a high end and a low end of an acceptable bearing gap range can be established, and the corresponding air gage readings obtained. Thus, once the air gage has been calibrated against a minimum and maximum gap, each motor can be assembled with the proper gap by simply adjusting the relative position of the parts until a target air gage reading or a reading between the high and low end of an acceptable range is obtained.
摘要翻译：间隙设定装置包括气量计，以测量空气通过流体动力轴承的间隙的压降（和间接的流速），同时轴承的相对部分移动得更靠近在一起。测量的压降可以与实际轴承间隙相关，并进行监测，以确定何时实现适当的间隙。更具体地，轴承的内部和外部元件被夹紧在分开的载体中并且保持就位。然后，托架彼此移动，使得轴承的内部或轴部分滑入轴承的外部或套筒部分。为了精确地设定两者之间的间隙，连接有气隙的空气软管连接到轴承间隙的一端; 空气被泵送通过轴承间隙，通过间隙的相对端离开。通过测试一组参考电机部件，可以建立可接受的轴承间隙范围的高端和低端，并获得相应的气量计读数。因此，一旦气隙已经根据最小和最大间隙进行校准，每个电动机可以通过简单地调节部件的相对位置来组装适当的间隙，直到目标气表读数或高低端之间的读数获得可接受的范围。

摘要： An apparatus for forming grooves in the surface of an article is disclosed. The apparatus includes a cage which has a circular cage wall with an annular pattern of holes in the wall. The apparatus also includes a plurality of spherical balls, each rotatably disposed in a respective hole of the cage wall and has a diameter greater than the wall thickness. The apparatus further includes a pin located within the cage, the pin has a circumferential groove in a plane coincident with the plurality of spherical balls and holes in the cage wall so that the pin holds the balls in the groove, the balls protruding through the cage wall and engaging the surface of a workpiece to be grooved so that the balls roll in the groove in the pin and, with movement of the workpiece and the apparatus, cause grooves to be formed in the interior surface of the workpiece. Lastly, the apparatus further includes an object at either end of the pin for holding the pin against translational movement relative to the cage with movement of the apparatus and the workpiece so that only a rotational movement is imparted to the pin by rotation of the workpiece.

摘要： An improved hydrodynamic bearing design and method for fabricating a hydrodynamic bearing is disclosed, which incorporates a filling groove so that oil or other lubricating fluid can be efficiently inserted into the bearing gap without risking the loss of fluid during operation; the method provides for fabricating the hydrodynamic bearing and its oil filling groove so that the efficiency of the manufacturing process is not compromised. The same grooving tool which forms the hydrodynamic bearing is scraped across an abutment on the sleeve which supports the counterplate to form a shallow filling groove under the counterplate.

摘要： A hydrodynamic bearing useful as a bearing cartridge or as the cartridge may be incorporated into a spindle motor or the like, where the bearing includes a stationary shaft and two independent bearings, comprising a top cone and a bottom cone separated by a segment of the shaft. The bearing includes a sleeve rotating around and surrounding the shaft, and the top cone and bottom cone and defining a narrow gap between the sleeve and the shaft and cones. Sealing plates are supported on the sleeve to seal off the ends of the bearing and are located along the shaft beyond the cones. A gap also exists between an interior surface portion of each cone and the shaft. Thus, separate flow paths are established, one around the top cone and one around the bottom cone. By providing two independent paths, the flow rates do not have to be the same in each conical flow path for the bearing seals to function properly.
