Robot includes an assembled component having a fixed member and a moving member. The moving member includes a multi-hole bar member and a multi-hole circular plate. The multi-hole bar member has a width four times longer than its thickness. The multi-hole bar member includes a set of connecting holes running through the multi-hole bar member along a thickness direction of the multi-hole bar member. The multi-hole circular plate has a central hole and fixed holes distributed around the central hole and arranged circumferentially. The fixed member includes a multi-hole plate and a multi-hole bent plate. The thickness of the multi-hole plate is the same as the thickness of the multi-hole bar member. A bent portion is formed by bending at least one end of the multi-hole bent plate. The fixed holes are arranged in a matrix on the multi-hole plate and distributed on the multi-hole bent plate in a matrix.

A device for power transmission includes a drive plate, a support plate, an output plate, a first main slide rail, a first drive train element, a first counterforce element, a first power transmission element, and a first output element, wherein the drive plate, support plate, and output plate are disposed above one another. The counterforce element generates a counterforce such that the total force from the driving force and the counterforce acting on the first main slide rail leads to a rotational movement of the support plate. The first power transmission element causes a rotational power transmission during rotational movement of the support plate and the first output element is connected to the output plate such that during the rotational movement of the support plate, an output power transmission connection exists from the moving part of the first main slide rail to the first output element.

A mixing apparatus is disclosed. The mixing apparatus includes a cradle assembly disposed within an enclosure wherein the cradle assembly is configured to receive a container for mixing. A crank is coupled to the enclosure is configured to rotate the cradle assembly by a rotational mechanism. The rotational mechanism may include a yoke coupled to a bottom portion of the cradle assemble and further coupled to the enclosure. The rotational mechanism may include a drive gear assembly for reducing force required on the crank.

A mechanism is introduced that allows transfer of mechanical rotational-energy generated in a liquid environment to a gas environment but does not allow the liquid to penetrate into the gas environment.

The invention relates to an articulated apparatus for guiding a relative movement of components into a target position, which may be the operating position of a micromanipulator arrangement. The articulated apparatus has multiple parts, which are movable with respect to each other. Two stop devices are used which, in combination, imitate the latching-in of a conventional latching device, but offer a considerably greater level of precision. A combined stop position is settable as said target position in which the first stop position and the second stop position are both present. The invention uses two stop devices in order to imitate the leaving of the latched target position in two directions as in the case of latching. Such articulated apparatus may be typically used with a micromanipulator arrangement of a cytobiological or microbiological workstation.

A rotary actuation mechanism comprising an actuator having a body, and a slider movable on a linear path relative to the body. A first linkage can be pivotally coupled to the body at a first pivot having a first axis. A second linkage can be pivotally coupled to the slider at a second pivot having a second axis, and pivotally coupled to the first linkage at a third pivot. A length of the first linkage between the first pivot and the third pivot can be equal to a length of the second linkage between the second pivot and the third pivot. The slider can be movable to position the second axis in a collinear relationship with the first axis. The rotary actuation mechanism can include an anti-singularity device to constrain movement of the body when the first axis and the second axis are in the collinear relationship.

An oscillatory drive is specified, having a housing in which there are accommodated a drive motor for driving a motor shaft in rotation and a tool spindle, and a first coupling drive mechanism which is coupled to the motor shaft and to the tool spindle for the purpose of driving the tool spindle in oscillatory fashion about its longitudinal axis, wherein a second coupling drive mechanism is coupled to the tool spindle such that the tool spindle performs a superposed movement composed of a rotary oscillating movement and a movement directed perpendicular to its longitudinal axis.

A method and system for imparting a linear motion to a flexible shaft is disclosed. The system includes a bellcrank having a first arm, a second arm, and a first pivot pin therebetween. The system further includes an actuating device coupled to the first arm and configured to apply a force to cause the bellcrank to rotate about the first pivot pin. Still further, the system includes a second pivot pin coupled to a rod-end of the flexible shaft and further coupled to a slotted hole on the second arm. Yet still further, the system includes a follower surface on the rod-end of the flexible shaft and configured to slide on a cam surface machined on the second arm. Upon application of the force to the first arm, the flexible shaft moves in a substantially linear motion.

A gearbox includes at least two engaged gears, with at least one of the two gears provided with a shroud positioned radially outwardly of the one gear. The shroud extends between circumferential ends which do not fully surround the one gear. An extension extends from the shroud to a component to be lubricated. A shroud is also disclosed.

A reciprocating drive mechanism for a power tool includes a rotatably mounted transmission shaft that has a first central axis, a spindle with a spindle body, and a counterweight for linearly reciprocating motion under the guide of at least one guiding rod. A wobble plate is mounted on the transmission shaft and includes a first arm and second arms extending in opposite directions. The first arm and second arms are configured to cooperate with the spindle and the counterweight respectively so that, upon rotation of the transmission shaft, the first and second arms of the wobble plate drive the spindle and the counterweight to reciprocate in opposite directions parallel to the second central axis. An angle is formed between the extending direction of the first arm and the second arm and a plane defined by the first central axis and the second central axis.
