摘要： A rotary clutch uses a wrap spring clutch. An actuator generates a drag force to control the wrap spring clutch to engage or disengage the clutch. The actuator includes an electromagnet, a two-component armature and an axial return spring. The two-component armature includes first and second components threadingly connected one another for relative axial translation as they rotate relative to one another, and an angular position biasing member connecting them. The second component translates axially under magnetic force from the electromagnet, and when stopped by the electromagnet the first armature component translates axially due to their threaded connection. Due to the previous axial movement of the floating component the translation of the first armature component occurs in conditions where the air gap and reluctance of a magnetic circuit is reduced compared to the prior art, and thus the overall strength of the applied magnetic field can be comparatively reduced.

摘要： In an aspect, an electromechanical apparatus is provided, comprising an electromagnet, a magnetically permeable rotor, a drive, a current source, a current sensor and processing logic. The electromagnet includes a magnetically permeable housing and a wire coil disposed therein. The rotor spins and is disposed in the path of a magnetic circuit generated by the electromagnet. The drive rotates the rotor relative to the electromagnet housing. The rotor and electromagnet housing vary the reluctance therebetween as the rotor rotates. The current source applies a current to the electromagnet coil, wherein, during rotation of the rotor, fluctuations in the current result in the electromagnet coil due to the aforementioned varying reluctance are superimposed on the applied current. The current sensor senses fluctuations in current in the electromagnet coil. The processing logic reads the sensed current and determines the frequency of the fluctuations, which are correlated to rotor speed.

摘要： A high-load linear actuator includes a driving mechanism, a worm shaft, a worm wheel assembly, a lead screw, a telescopic pipe and an outer pipe. The driving mechanism includes a base and a motor. The base has a supporting portion and an accommodating portion. The motor is fixed to the supporting portion. The worm shaft extends from the motor into the supporting portion. The worm wheel assembly includes a worm wheel and two bearings for supporting the worm wheel in the accommodating portion. The worm wheel is engaged with the worm shaft. The lead screw is disposed through the worm wheel and driven by the motor for rotation. The telescopic pipe slips on the lead screw to be threadedly connected therewith. The outer pipe slips on the telescopic pipe. The rotation of the lead screw drives the telescopic pipe to linearly extend or retract relative to the outer pipe.

摘要： A motor drive unit assembly for a motorized drapery system having a drapery fabric can include a motor having a drive shaft, an output member rotatable about a drive axis, such that rotation of the output member about the drive axis causes the drapery fabric to move, and a clutch member operatively coupled between the drive shaft of the motor and the output member. The clutch member is configured to automatically couple the output member to the drive shaft such that rotation of the motor drive shaft causes the output member to rotate about the drive axis when the motor drives the drive shaft. The clutch member is further configured to automatically decouple the output member from the motor drive shaft so that the output member rotates about the drive axis relative to the motor drive shaft when the output member is manually driven.

摘要： A mechanism for changing the operating condition of a shifting element having two shifting element halves, which can either be functionally connected to connect two components or disengaged to break the connection between the components. The mechanism includes a drive machine and a drive converter unit in the area of which rotary drive motion of the drive machine can be converted into a translational actuation movement of the shifting element. A spring device is associated with the drive converter unit, whose spring force assists with actuating the shifting element in the engaging direction. The spring device includes an approximately circular flat spring element which, in at least one area of the drive converter unit, is in contact with at least one cam, whose stress condition varies as a function of an operating condition of the drive converter unit and is designed to be rotationally fixed.

摘要： A rotary impulse tool has a motor-driven drive shaft and an output shaft. The drive shaft is threadedly coupled to a flywheel sleeve, which is spring-biased forwardly and is splined to a rotatable race structure of a wrap spring clutch assembly, which includes a wrap spring disposed in clearance fit coaxially between cylindrical surfaces of the race structure, the wrap spring having a front end fixed to the output shaft and a rear end coupled to a first conical control member. A second conical control member is axially movable between engaged and disengaged positions relative to the first control member for, respectively, shifting the clutch assembly to an engaged condition for transmitting torque between the drive and output shafts and a disengaged condition for decoupling those shafts. When the clutch assembly is engaged, the drive shaft rotates the output shaft and, as torque builds up on the output shaft, it slows to develop a speed differential between the drive and output shafts, which retracts the flywheel sleeve rearwardly against a compression spring to engage the second control member and move it axially to its disengaged position for disengaging the clutch assembly, whereupon the flywheel sleeve rapidly rotatably and axially returns forwardly, engaging the second control member to move it back to its engaged position and reengage the clutch assembly to transmit the kinetic energy of the flywheel sleeve in an impulse to the output shaft.

摘要： A spring clutch includes a driving-side boss integrally formed with a driving gear and a driven-side boss having a feed roller fixed. The driving-side and driven-side bosses are arranged on a common axis so as to be opposed to each other. A coil spring is wound on the peripheral side of the driving-side boss and driven-side boss. The spring clutch further has a sleeve fitted over the coil spring while a driving-side coil end of the coil spring is engaged with the sleeve. As rotation of the coil spring and the sleeve is restricted by a projection formed on the peripheral surface of the sleeve, the coil spring is idly fitted on the driving-side boss so that the rotation of the driving-side boss is not transmitted to the driven-side boss while the reverse rotation of the driven-side boss is restricted.
