摘要： Electric actuators having internal load apparatus are described herein. An example electric actuator having an internal load apparatus described herein includes a housing defining a cavity to receive a drive system and a drive shaft operatively coupled to the drive system. Rotation of the drive system in a first rotational direction causes the drive shaft to move in a first rectilinear direction and rotation of the drive system in a second rotational direction causes the drive shaft to move in a second rectilinear direction opposite the first rectilinear direction. A biasing element is operatively coupled to the drive system such that least a portion of the drive system moves axially toward the biasing element to deflect the biasing element when the drive shaft reaches an end of stroke position to provide a load to the drive shaft when electric power to the electric actuator is removed.

摘要： Coupling apparatus for use with electric actuators are described herein. An example coupling apparatus described herein includes a coupling assembly to operatively couple a fluid flow control member of a fluid valve and a drive system of the electric actuator. Rotation of the drive system in a first rotational direction causes the coupling assembly to move in a first rectilinear direction and rotation of the drive system in a second rotational direction causes the coupling assembly to move in a second rectilinear direction opposite the first direction. The coupling assembly includes a biasing element that is to be deflected to provide a seat load to the fluid flow control member when the fluid flow control member is in sealing engagement with a valve seat of the fluid valve and electric power to the electric actuator is removed.

摘要： A spindle shaft is flexurally elastic at its shank part mounted in a bearing sleeve. The spindle shaft carries a belt-engaging wharve which is arranged underneath the neck bearing and to which a drive belt engages to rotate the spindle shaft. The bearing sleeve is arranged to have radial play within a spindle housing 10. The bearing sleeve is fastened at its lower end via a flexurally elastic tilting joint 40 to the spindle housing 10 connected rigidly to the spindle rail. The pulling force of the drive belt engaged to the wharve during operation deflects the bearing sleeve radially by tilting it about the tilting joint. Such deflection brings about, on the other hand, a pivoting of the bobbin-carrying upper part of the spindle shaft about the neck bearing in the opposite direction as a result of the bending moment occurring on the shank part, an inclination of the spindle shaft with its upper part is thus avoided.

摘要： This invention relates to apparatus and methods for z-axis control and collision detection and recovery for waterjet and abrasive-jet cutting systems. In one embodiment, an apparatus includes a linear rail, a slide member coupleable to a cutting head and slideably coupled to the linear rail, at least one actuator having a first end coupled to the slide member and a second end fixed with respect to the linear rail, a position sensor, and a controller. The actuator provides an adjustable support force that supports the weight of the cutting head, allowing the cutting head to be controllably positioned at a desired height above the workpiece. The actuator may include a pneumatic cylinder, or alternately, a linear motor. In another aspect, an apparatus includes a first mount member coupleable to a controllably positionable mounting surface of the waterjet cutting system, a second mount member coupleable to the cutting head and disengageably coupled to the first mount member, and a sensing circuit having a plurality of first conductive elements disposed on the first mount member and a plurality of second conductive elements disposed on the second mount member. In the event of a collision between the cutting head and an obstruction, the second mount member disengages from the first mount member to prevent breakage of the cutting head. Following the collision, the second mount member is quickly and easily re-engaged with the first mount member without time-consuming re-calibration. In one embodiment, re-engagement of the second end first mount members is automatically performed by a biasing member.

摘要： In the case of weapon barrels which are only secured at one of their ends at the weapon housing during firing of the weapon there occurs, particularly during series firing, bending vibrations or oscillations which impair the hit probability of the fired projectiles. In order to preclude or at least dampen such bending vibrations of the weapon barrel the invention contemplates securing a vibration damping device or damper at the muzzle of the weapon barrel. This vibration damper comprises an inertia body which is resiliently connected with the weapon barrel muzzle. Also provided is a brake device which dampens the movement of the inertia body relative to the weapon barrel. The inertia body preferably comprises two ring members which are pressed by springs against two disc members which are rigidly attached to the weapon barrel muzzle. Between the weapon barrel and the ring members of the inertia body there are arranged resilient elements, such as blade or leaf springs.

摘要： An apparatus for generating and manipulating a high-pressure fluid jet includes an assembly coupled to a motion assembly that imparts motion to the assembly along one or more axes. The motion assembly includes two motors coupled together to form a gimbal wrist, each motor having an axis of rotation. The two axes of rotation of the two motors can be perpendicular to each other, but are not necessarily aligned with the manipulator's axes of motion. The high-pressure fluid assembly incorporates a swivel that can rotate about two axes which may be parallel to the two motors' axes of rotation, allowing the high-pressure tubing contained therein to follow the motion imparted by the gimbal wrist of the motion assembly.
