The present invention relates to a universal coupling (3) for transferring rotary movements between an input shaft (1) and an output shaft (2), wherein each of the shafts are arranged to rotate about a longitudinal axis (L1, L2) of the shaft, the coupling comprising: an input joint member (5) and output joint member (6) movably coupled to each, and the input joint member is fixedly connected to the input shaft and the output joint member is fixedly connected to the output shaft. Each of the input and output joint members comprises at least one annular part (8, 12) having a cross section and defining a central aperture (9,13), the annular part of the input joint member passes through the aperture of the annular part of the output joint member, and the annular part of the output joint member passes through the aperture of the annular part of the input joint member, and the area (A) of each the central apertures is at least three times larger than the cross section area of each of the annular parts and two spaced apart contact points (16,17) are formed between the annular parts of the input and output joint members.

In an aspect, an isolator is provided, comprising a hub, a pulley, an isolation spring and a transition spring. The hub defines an axis and is connectable to a rotatable shaft of a rotary device. The pulley is rotatably mounted to the hub. The isolation spring and transition spring act in series in a torque path between the pulley and the hub. The isolation spring has a first spring rate. The transition spring has a second spring rate that is lower than the first spring rate.

A scissor gear assembly (1) has a main gear (3) and auxiliary gear (5) concentric to the main gear and in axial direction near the main gear. Further the assembly has a planar annular spring (7) being interrupted at one place. At the interruption the spring has two ends (7A) and (7B). The spring is present between both gears and is with one end (7A) connected to the main gear (3) and with the other end (7B) to the auxiliary gear (5), so that both gears are connected to each other in rotation direction via the spring. Each end (7A, 7B) of the spring is provided with an extension (9) forming extra mass. These extensions are each provided with a slot (13). Because of these extra masses the spring torque will vary depending on the rotational speed of the gear assembly.

The present invention relates to a rotational force driving assembly and a process cartridge used for being engaged with a rotational force driving head inside an electrophotographic image forming device so as to transmit rotary driving force, comprising a photosensitive member hub, a rotational force receiving component, a side plate, and an axis offset adjusting mechanism of the rotational force receiving component, wherein the axis offset adjusting mechanism can slide relative to the side plate; the axis offset adjusting mechanism of the rotational force receiving component is connected with the rotational force receiving component; when the rotational force driving assembly is not installed into the electrophotographic image forming device, and thus is not subjected to external force, the axis offset adjusting mechanism enables the axis of the rotational force receiving component to make parallel offset relative to the axis of the photosensitive member hub; and after the electrophotographic image forming device is arranged in the rotational force driving assembly and is installed in place, the axis offset adjusting mechanism is subjected to the external force to move relative to the side plate, so that the axis of the rotational force receiving component is coincident with the axis of the photosensitive member hub, the rotational force receiving component extends out along the axial direction of the photosensitive member hub to be engaged with the rotational force driving head, and the driving assembly does not interfere with the rotational force driving head.

The present invention relates to transferring torque between a first unit, which is typically a mobile machine or a robot, and a second unit, which is typically a fixed or stationary machine. The units are arranged such that a drive coupler of the first unit designed for delivering torque about a drive axis can engage the driven coupler, which belongs to the second unit and has a driven axis, along an engagement direction that is nearly perpendicular to the direction of the driven axis. A lateral displacement mechanism in provided is in the first unit to achieve a first-order coaxial alignment between the drive and driven axes. Additional measures such as compliance mechanisms are provided for improving engagement, coupling and reducing the level of axial misalignment in the apparatus and methods of the invention.

A device for reducing an actuation force spike in an elevator car safety system. The device includes an elevator car mounted overspeed governor, a safety gear, a safety lever, and a force reducing mechanism. The force reducing mechanism is connected in a series relationship with the safety lever between the overspeed governor and the safety gear.
摘要:
Es wird ein Doppelkurbelwellen-Verbrennungsmotor vorgeschlagen mit mindestens einem Zylinder, in dem ein Hubkolben hin- und herbewegbar angeordnet ist. Der Motor hat eine erste und eine zweite Kurbelwelle, wobei die beiden Kurbelwellen zueinander parallel verlaufen und sich gegensinnig synchron drehen. Dem Hubkolben sind ein erstes und ein zweites Pleuel zugeordnet, wobei das erste Pleuel mit seinem ersten Ende in einem ersten Schwenklager um eine erste Pleuelschwenkachse schwenkbar gelagert ist und mit seinem zweiten Ende an einem Kurbelzapfen der ersten Kurbelwelle drehbar gelagert ist. Entsprechendes gilt für das zweite Pleuel. Ferner ist am Hubkolben des Motors ein Lagerelement vorgesehen, das am Hubkolben um eine Lagerschwenkachse schwenkbar gelagert ist, die parallel zu den Pleuelschwenkachsen verläuft. Das erste und zweite Schwenklager sind an dem Lagerelement vorgesehen. Der Motor hat schließlich Mittel zur Phasenverschiebung der beiden Kurbelwellen gegeneinander. Dadurch lässt sich das Verdichtungsverhältnis im laufenden Betrieb variabel einstellen, ohne dass die Alltagstauglichkeit des Motors beeinträchtigt wird. Durch die variable Verdichtung wird eine erhebliche Kraftstoff-Einsparung erreicht.
