摘要： An electric motor-brake assembly includes a housing within which a rotor assembly, a stator assembly, and a brake assembly are disposed. The brake assembly is operable between an engaged state and a disengaged state. The rotor assembly is axially movable within the housing and is supported by bearings supporting both radial and axial loads. When the motor stator is de-energized, the brake assembly is in the engaged state to prevent the rotor assembly from rotating in at least one rotational direction. When the motor stator is energized, the brake assembly is in the disengaged state such that the rotor assembly is free to rotate. The brake assembly can include a friction pack that is engaged and disengaged by axial displacement of the rotor assembly.

摘要： A lift drive system for an energy storage and delivery system includes an electric motor that rotates a driven shaft, a brake assembly for selectively braking the rotation of the driven shaft, and optionally includes a clutch selectively operable to decouple the electric motor from the driven shaft. A steel ribbon is disposed at least partially about and in contact with the driven shaft, where rotation of the driven shaft by the electric motor causes linear movement of the steel ribbon. The steel ribbon can connect at one end to an elevator cage assembly and at an opposite end to a counterweight.

摘要： A one-way clutch structure includes: a pair of clutch members disposed between an output shaft and a drive shaft so as to oppose each other in an axial direction; and an engagement element interposed between these clutch members. When a rotation speed of the output shaft exceeds a rotation speed of the drive shaft, the engagement element engages with the clutch portion to connect the output shaft and the drive shaft so as to be integrally rotatable. When the rotation speed of the output shaft becomes lower than the rotation speed of the drive shaft, the engagement of the engagement elements is released to cut off connection between the output shaft and the drive shaft.

摘要： A reduction gearset for use on an electric vehicle having a motor. The reduction gearset has an input shaft, a reduction mechanism equipped with an input pinion, and a selector device for connecting the input shaft to, or disconnecting the input shaft from, the input pinion. The motor power is transmitted to the input shaft. The input pinion is rotatable relative to the input shaft. The selector device consists of a sleeve spline fit to both input shaft and input pinion. The sleeve can slide axially of the input shaft. A slidable shift shaft is mounted parallel to the input shaft. A shift fork is fixedly mounted to the shift shaft. The sleeve is made to engage the shift fork. The sleeve is moved forward or rearward by moving the shift shaft forward or rearward. Thus, the input pinion is coupled to, or uncoupled from, the input shaft.

摘要： An electromotive variable-speed and control drive particularly for use in industrial sewing machines and comprising a coupling coil casing radially surrounding a coupling-brake disk and a brake coil casing radially relocated towards the center. Both are positioned in the brake end shield. In order to avoid a sticking of the coupling-brake disk with high alternations and a delay of the break-down and build-up of the magnetic fields, a brake coil casing has been relocated radially so near to the center that it is situated within the brake pad in front of the armature ring. On the other hand, there is an undercut and a recess at the coupling coil casing and a recess at the disk flywheel which assures that no axial forces can occur at the radial gaps.
