摘要： In accordance with an example embodiment, a mower-conditioner may include first and second conditioning rolls, at least one eccentric, and a linkage having a lever. The first and second conditioning rolls are spaced apart a distance. The at least one eccentric is coupled to the mower-conditioner. The lever is coupled between the eccentric assembly and the first conditioning roll. The rotation of the at least one eccentric about a pivot axis causes the first conditioning roll to move via the lever, which adjusts the distance between the first and second conditioning rolls.

摘要： A head mechanism includes a base connectable to a body of a robot, a mounting member arranged above the base, a connecting member rotatably connected to the base and the mounting member. The connecting member, together with the mounting member, is rotatable relative to the base about a first axis, and the mounting member is rotatable relative to the connecting member about a second axis. The first axis and the second axis extend in different directions. The head mechanism further includes two first actuating mechanisms fixed to the base, and the two first actuating mechanisms are configured to drive the mounting member to rotate with respect to the base.

摘要： An apparatus for unlocking an actuator comprises a first member mounted in a housing for longitudinal movement along an axis. A recess is formed in a surface of the first member. The apparatus further comprises a second member for operative connection to a lock release element of an actuator for movement in a direction generally transverse to the axis of movement of the first member. The second member has a follower element resiliently biased into contact with the surface of the first member. The apparatus further comprises an unlocking actuator for moving the first member along the axis between a first, locking position in which the follower element engages the surface and a second, unlocking position in which the follower element is at least partially received within the recess.

摘要： A linear delta system includes a support frame, rails mounted to the support frame, linear actuators, each linear actuator configured to translate along a longitudinal length of a respective rail, pairs of parallel rods each coupled to the linear actuators, a platform coupled to a longitudinal end of each of the pairs of parallel rods opposite the respective linear actuator, and an object coupled to the platform. Longitudinal axes of the rails are oriented parallel to each other and lie within a common plane or an uncommon plane. A method of forming a linear delta system includes mounting rails to a support frame, the rails having longitudinal axes that are parallel to each other and lying within a common plane, coupling a linear actuator to each of the rails, coupling a pair of parallel rods to each linear actuator, and coupling a platform to the pairs of parallel rods.

摘要： A driving apparatus according to an embodiment includes an arm, an operation target, and a brake unit. The arm has one end supported by a support mechanism, and includes an electric driving source. The operation target is attached to the other end of the arm, the other end being an end on the opposite side of the one end, and is enabled to be pivoted by the driving source about one rotational axis intersecting with a direction from the one end to the other end. The brake unit secures immobility of a target gear that is a gear disposed in the arm, and that is a gear being rotated as the operation target is pivoted, when the power supply to the driving source stops.

摘要： This invention is related to a mechanical force generator (MFG) (11), the cost, the maintenance costs and the energy consumption of which have been minimized, as much as possible, since the reaction forces, the reaction moments and the frictional forces at the joints that connect the mechanism to the ground have been minimized as much as possible; which does not possess any actuators; and which can generate any desired force variation. MFG (11) may be obtained by using 3 novel kinematic chains. By using these kinematic chains, it is also possible to obtain general purpose mechanisms, which have advantages similar to the MFG (11); which may include an actuator; which may generate relative translational motion at a joint as any desired function of relative translational motion at another joint; which may be used in many different fields such as hydraulic and pneumatic machines, internal combustion engines and compressors.

摘要： A working device (1) using a parallel link mechanism includes: a parallel link mechanism (10) by which end effectors (4, 5) are supported so as to be changeable in posture; and posture-controlling actuators (11) which actuate the parallel link mechanism (10). In the parallel link mechanism (10), a distal-end-side link hub (13) is connected to a proximal-end-side link hub (12) via three or more link mechanisms (14) so as to be changeable in posture of the distal-end-side link hub (13) relative to the proximal-end-side link hub (12). The end effectors (4, 5) are mounted to the distal-end-side link hub (12), and includes one main end effector (4) which performs a main work on a workpiece (3) and one or multiple sub end effectors (5) which perform an auxiliary work on the workpiece (3).
