摘要： The method includes sliding a first shim onto the support shaft until it abuts a shoulder. The first shim has a predetermined thickness. A bearing is then slid onto the tapered surface and a lock nut is tightened onto the threaded portion of the shaft. As the lock nut contacts the inner race of the bearing it causes the inner race to contact the first shim and also to radially expand outwardly, thereby preloading the bearing. The outer race of the bearing is then connected to a motor and the motor is operated at a predetermined, constant speed. The torque required to rotate the outer race of the bearing is measured and compared to a predetermine torque range to determine if the bearing is precisely preloaded.
摘要翻译：该方法包括将第一垫片滑动到支撑轴上，直到其抵靠肩部。第一垫片具有预定的厚度。然后将轴承滑动到锥形表面上，并且将锁定螺母紧固到轴的螺纹部分上。当锁紧螺母接触轴承的内圈时，它使得内座圈接触第一垫片并且还向外径向膨胀，从而预先加载轴承。然后将轴承的外圈连接到电动机，并且电机以预定的恒定速度运行。测量旋转轴承外圈所需的扭矩，并将其与预定扭矩范围进行比较，以确定轴承是否精确预加载。

摘要： A non-rotating and axially secured connection between an inner joint part of a constant velocity joint and a driveshaft has an inner joint part at its outer circumference with tracks for receiving torque-transmitting balls or tripod arms for sliding on rollers, as well as a central bore with inner teeth. The driveshaft is inserted into the bore and is provided with corresponding outer teeth. At the end of the inner joint part facing the shaft end, the bore, with its inner teeth, changes into a through-hole with a smaller diameter. At the end of the driveshaft in front of the outer teeth, a cylindrical portion is provided carrying an axial securing mechanism.

摘要： A method for producing flanged bearings is described in which the blank (10) is punched out, forming at least two extension and holding portions (9, 9′), by means of which the blank (10) remains connected with the strip or the neighbouring blank during shaping. The flanged bearing is separated from the extension and holding portions (9, 9′) once shaping is complete. A device for shaping blanks is also described, which comprises a die and a die barrel, as well as on each side a slide displaceable for the purpose of forming the flange.

摘要： A machine tool comprising a base, with a guide surface, a workpiece holder on the base, a movable tool carriage, and a motor for advancing the carriage along the guide surfaces toward the workpiece. Hydrostatic bearings are situated in the carriage for discharging fluid, such as oil, into the narrow gap defined between the carriage and the guide surface. A pre-load rail is secured to the movable carriage, and a plurality of pockets are defined in the pre-load rail. A hydrostatic pre-load piston, with an enlarged head and a depending base, is located in each pocket. A shallow depression is formed in the face of each piston, and an annular wall surrounds the depression, so that the piston restores itself to an equilibrium condition. The pre-load pistons are located in opposition to the hydrostatic bearings. An O-ring encircles the base of the piston, and allows floating, and tilting, movement of the piston within the pocket, while serving as a seal for the pocket. The individual pre-load pistons float and tilt to accommodate diverse localized distortions, anomalies, imperfections, and machining errors in the carriage and in the guide surface.

摘要： The preload of the double row rolling bearing unit after completion is kept at a proper value regardless of the elastic deformation of the shaft caused when pushing the inner race in the axial direction wherein the balls are first installed in the bearing at the first pitch P1 of the ball rows which is larger than the pitch p1 in the state where the preload is proper and then preloaded to a pitch slightly smaller than the second pitch p1, so that the ball rows have the second pitch p1 after the shaft is elastically restored.

摘要： A caulked portion is formed by plastic deformation of a cylindrical portion which is formed at the inner end of a shaft member and is reduced in thickness toward the leading end in a diametrical outward direction. The force required to form the caulked portion is reduced, and the caulked portion is less susceptible to damage. Further, the force of the caulked portion for supporting the inner ring is ensured.

摘要： A method for setting one or more hydrodynamic bearing gaps in a disc drive spindle motor is provided. In one embodiment, a method setting one or more hydrodynamic bearing gaps in a disc drive spindle motor includes disposing a rotary member against one or more working surfaces such that substantially no gap exists therebetween and inducing creep between the rotary member and the working surfaces. The creep creates a bearing gap therebetween the rotary member and at least one of the working surfaces. The creep may be induced by thermally cycling the motor components or applying a force to a tool coupled to a member having at least one of the working surfaces disposed thereon.

摘要： A ball screw device utilizes spacers having concave ball-contacting surfaces with distributed protrusions or dimples. Balls having needle-like recesses may also be used. The spacers are provided in two thicknesses, and the relative numbers of the thinner and thicker spacers are selected in order to ensure retention of the spacers in their proper positions, while providing a small clearance between the balls and spacers to avoid fluctuations or sharp increases in dynamic torque.

摘要： A hub (2) includes a spindle (14) which projects through a housing (4) and rotates relative to the housing (4) on a bearing (6) that is located between the spindle (14) and the housing (4). The bearing (6) has two sets of raceways (28,40) that are oblique to the axis x, and in addition rolling elements (36) arranged in two rows between the sets of raceways (28,40). The inner raceways (28) that fit around the spindle (14) and have back faces (32), with the back face (32) for one of the races (26) being against a shoulder (18) from which the spindle (14) projects. Initially, the end of the spindle (14) projects straight beyond the back face (32) of the outer race—indeed, so that the races (26) can be installed over the spindle (14). But once the housing (4) and races (26) are in a position around the spindle (14), the projecting end portion of the spindle (14) is deformed radially and axially in a rotary forming operation such that it transforms into a formed end (20) that lies behind back face (32) of the race (26). With the two races (26) between the formed end (20) and the shoulder (18). During the rotary forming operation the hub (26) rotates, and the end of its spindle (14) is forced against a rotating forming tool and the force is monitored. The housing (4) is restrained and the torque transferred from the rotating hub (2) to the housing (4) is monitored.
