A machine tool assembly includes a high speed rotating spindle for forming extremely precise surface contours on a work piece. The spindle is supported on a spherical air bearing about its center of gravity. The spindle can be rotated through an air turbine drive system incorporated into the spherical air bearing to eliminate any undesirable moments about an axis perpendicular to the long spindle axis. The spindle is adjustable in pitch and yaw directions through the influence of X-Y actuators. The X-Y actuation system is preferably electromagnetic and provides a non-contact method of displacing the spindle shaft in a controlled manner at any speed.

In a wheel support bearing assembly having rows of rolling elements (3) interposed between an outer member (1) and an inner member (2), spacers (27) are interposed between vehicle body fitting holes (9) in the outer member (1), which is a stationary member, and a knuckle (25). A sensor unit (16) including a sensor mounting member (17) and a strain sensor (18) is fitted to the outer member (1). The sensor mounting member (17) has at least two contact fixing portions (17a, 17b) fixed to the outer member (1) and, also, has at least one recess (17c) between the neighboring contact fixing portions (17a, 17b), the strain sensor (18) being disposed in this recess (17c).

A ball and socket joint for a motor vehicle is provided with a joint housing (2), with a ball pivot (3), which is mounted rotatably and pivotably in same and which is in contact with the joint housing (2) or with a ball shell (7) arranged between this and the ball pivot (5). The ball and socket joint has an angle measuring device (20, 21), by which the angle of the ball pivot (5) relative to the joint housing (2) can be detected. At least two temperature sensors (15, 16) are arranged at spaced locations from one another in or on the joint housing (2).

A bump stop device comprises a bearing 20 provided with two bottom 22 and top 24 metal washers between which rolling bodies 26 are arranged. A friction ring 34 is fixed to the first of the bottom and top metal washers and rubs against the other metal washer in order to create a static frictional torque that is greater than that of the rolling bodies and, in practice, greater than 1 Nm. The friction ring 34 makes it possible to generate a controlled resisting torque that limits the transmission to the steering column of the torque generated when driving the vehicle on a convex road.

A slider device includes a base (200), a running head (300) slidably provided on the base (200), a main guide mechanism (410) for guiding in a first direction in which the running head (300) runs, and sub-guide mechanism (450) allowing displacement to a second direction different from the first direction. The main guide mechanism (410) includes two main rails (421, 422) provided on the base (200) substantially parallel to each other along the first direction, and main sliders (431, 433) sliding on the main rails (421, 422). The sub-guide mechanism (450) includes a sub-rail (461) provided on the main slider (431) along the second direction, and a sub-slider (471) sliding on the sub-rail (461).

A linear roller bearing is provided having a guide carriage (1) which can be mounted on a guide rail (2) in a rolling manner via roller bodies (4). The guide carriage is provided with at least one continuous roller body channel (3) for the roller bodies (4). The roller body channel (3) includes a support channel (5) for supporting the roller bodies (4), a return channel (11) for returning the roller bodies (4), and deflecting channels (10) which connect the support channel (5) to the return channel (11). The deflecting channels (10) are provided in end elements (9) of the guide carriage (1), and the roller bodies (4) in the roller body channel (3) are subject to displacement resistance in the direction of rotation. The end elements (9) are respectively provided with a sensor (12), whereby a preferably electric sensor signal therefrom is dependent on the displacement resistance.
摘要:
A contact assembly of an alternator including an interior chamber, which houses a first end of a rotor shaft having an axis of rotation, first and second bearing assemblies coaxially aligned with the rotor shaft and electrically isolated from one another; and at least one spring member coaxially positioned with respect to the rotor shaft within the chamber. The spring member(s) exerts resistive forces into at least one of the first and second bearing assemblies and support structures within the interior chamber in order to compressively sandwich the first and second bearing assemblies within the interior chamber. The contact assembly may also include capacitors electrically connected to the bearing assemblies.

摘要:
In order to achieve direct digital data recording and reliable and space saving and cost saving recording of the status of an antifriction bearing, in particular a wheel bearing for motor vehicles, sensors record the rotational speed and acceleration of the wheels and driving and/or braking forces. The sensors are microsensors in the form of microswitch arrays, at least one of which is attached to the rotating ring of the bearing, and the generated signals are compared with stored basic patterns or with the signals of an identical or similar microsensor arranged on the stationary ring of the bearing and/or are evaluated.
