摘要： A structure of a rotation locking device that is easily configured and capable of keeping cost down is achieved.
A rotation locking device 4 switches between a first mode where an engaging claw portion 14 engages with an engaging concave portion 9 by an output member 13 rotating an engaging member 8 due to an input member 12 being rotationally driven by an actuator 7, and rotation of a locking gear 5 supported by and fixed to an output shaft 3 of an automatic transmission 2 is restricted, and a second mode where engagement between the engaging claw portion 14 and the engaging concave portion 9 is released and rotation of the locking gear 5 is allowed.-

摘要： A diverter valve includes a diverter valve assembly, a diverter valve transmission assembly, a drive motor and a control device used to control the drive motor. Controlled by the control device, the drive motor drives the diverter valve transmission assembly to perform a transmission action, so as to drive the diverter valve assembly to perform switching actions. The diverter valve transmission assembly is an intermittent gear transmission assembly. Driven by the drive motor, each time the intermittent gear transmission assembly performs the transmission action at least once, the control device controls the drive motor to stop driving. In this way, during the action process, not only the transmission is stable and reliable, the noise is low, but it is also wear-resistant enough under high-frequency use, which can meet the requirements of long-term working consumption of the beverage machine.

摘要： Disclosed herein are multi-turn drive assemblies, systems and methods of use thereof. The multi-turn drive assemblies enable a robot link member to have a maximum rotation of at least 360 degrees about an axis. The multi-turn drive assemblies can be incorporated into a robot arm for enabling 360 degrees rotation of one or more link members about an axis. The robot arm may be located in a transfer chamber of an electronic device processing system. Also disclosed are methods of controlling the multi-turn drive assemblies and related robots.

摘要： A force-shunting device including a tube defining a main axis and an inner wall, a first member sliding within the tube, a primary leg arranged obliquely, attached to the first member and including a primary pad in frictional contact with the inner wall, such that, when an external force is applied in a first direction on the first member, the primary leg rubs, or grips by mechanical camming, against the inner wall, the tube thus reacting all or part of the external force, the device including a second member mounted within the tube, sliding along the main axis and securely provided with a driving element of the primary pad so as to reduce the friction on the inner wall, to unprime the rubbing or mechanical camming.

摘要： A plurality of shape memory alloy tubes (SMTs) of one or more shape memory alloy (SMA) types is configured as an element in a rotary actuator system in a nested manner. In various configurations, the nested SMTs provide one or more modes of multiplication (torque output or angular displacement), rotation reversibility and bias loading. The innovation provides for leveraging the modes for reductions in the rotary actuator system size, weight, or complexity or combinations thereof, or providing improved and more stable actuation capabilities in a given envelope.

摘要： A gear arrangement comprising: a housing having a gear axis and a housing stop, the housing stop having a first abutment and an second abutment spaced apart from one another about the gear axis; a rotatable member mounted on the gear axis, the rotatable member having a first member side having a first member stop and a second member side having a second member stop, the first member side opposite the second member side, such that the first member stop is positioned between the first abutment and the second abutment; and a gear mounted on the gear axis, the gear having a first gear side, and a second gear side having a gear stop, the first gear side opposite the second gear side, such that the gear stop is engageable and disengageable with the second member stop during rotation of the gear about the gear axis, the rotatable member positioned between the housing and the gear; wherein said rotation of the gear is hindered while the gear stop and the second member stop are engaged when the first member stop enters into engagement with either the first abutment or the second abutment.

摘要： An engine variable camshaft timing phaser (10) includes a sprocket (12), three ring gears (26, 28, 30), multiple planet gears (24), and a sun gear (22). The sprocket (12) receives rotational drive input from an engine crankshaft. One or more of the three ring gear(s) (26, 28, 30) receives rotational drive input from the sprocket (12) and rotates with the sprocket (12), and the remaining ring gear(s) (26, 28, 30) transmit rotational drive output to an engine camshaft (62). All three of the ring gears (26, 28, 30) engage with the planet gears (24). And the sun gear (22) also engages with the planet gears (24). In operation, relative rotational speeds between the sprocket (12) and the sun gear (22) causes the engine camshaft (62) to advance or retard engine valve opening and closing.
