Modelling and Simulation of a Straight Line Motion Mechanism for US20140026705A1 - Scott russell mechanism device - Google This paper describes the design of an exact straight line motion mechanism, commonly known as a Scott-Russell mechanism (SRM), for industrial application. In certain design requirements such as design of production machinery it is desirable to have more accurate straight line paths or sometimes it becomes inevitable to have exact straight line trajectories of mechanisms. As point A moves vertically, point B moves horizontally. The Scott-Russell mechanism gives a theoretically linear motion by using a linkage form with three portions of the links all equal, and a rolling or sliding connection. for multi-joint type robot, Gravitation balancing device, articulated robot, and wrist device for robot, Manipulator with flat or three-dimensional trajectory suitable for high operating rate, Mechanical arm with a 2 freedom-degree wrist attitude regulation mechanism, Exhaust gas purification catalyst and method for producing the same, Motor-driven device for moving workpieces, Pick and place device having two parallel axes, Scara type robot with counterbalanced arms, Manipulator, manufacturing machine and production line using the same. Therefore, the rotation unit can perform the postural displacement in a different range from the case of coupling in an order different from the above, and the application of the Scott Russell mechanism device according to the present invention further expands. The application of the Scott Russell mechanism device according to the present invention expands by attaching various kinds of units corresponding to various applications to its rotor. Furthermore, in the Scott Russell mechanism device according to the present invention, a rotation unit having a rotor may be coupled to the joint unit. an angle changer for changing a coupling angle between the main arm member and the sub arm member. One link is double the size of the other, and is connected to the smaller link by its midpoint. wherein the device comprises a pivoting drive source for driving the pivots of the main arm member and the sub arm member centering on the pivoting axis. The First World War brought about much destruction and horror to extents that the world had never before seen. Moreover, in the present invention, the base end part of either one of the sub arm member or the main arm member is linearly movable by the second ball screw. The first exact straight line generating mechanism was invented by a French army officer Charles Nicolas Peaucellier in 1864. Therefore, compared to the conventional device, a drive torque caused by the turning can be reduced, and both of the arm members can be turned smoothly. Jasen Russell tendre la recherche. Moreover, in the present invention, pivoting member is pivotably coupled to the joint unit and the rotation unit having the rotor is coupled to the pivoting member. The angle changer may have a first ball screw arranged in parallel to the virtual straight line, and a first linearly-moving unit for being linearly moved by a rotation of the first ball screw. With the suffering came a wave of change that saw millions after their opinions towards not only war, but life itself. The movement of a body, or link, is studied using geometry so the link is considered to be rigid.

The Scott Russell mechanism device of, 18. This mechanism is called as Peaucellier Exact Straight Line Mechanism and commonly more as Peaucelliers linkage. Debates (Hansard) No. Moreover, in the Scott Russell mechanism device according to the present invention, a pivoting member may be pivotably coupled to the joint unit. a second ball screw arranged in parallel to the first ball screw; and, a second linearly-moving unit for being linearly moved by a rotation of the second ball screw, and, wherein either one of the base end part of the sub arm member or the base end part of the main arm member is pivotably coupled to the second linearly-moving unit about the virtual straight line as the pivoting axis thereof. Therefore, the rotation unit attached to the joint unit via the pivoting member can displace its rotor independently of the amount of the displacement of the tip end part of the main arm member, and the postural displacement of the rotor positioned at the farthest tip end increases much more. Owner name: The mechanism with bridge-type flexure hinges is developed and optimized to amplify the displacement of a multilayer piezostack by Kim et al. Therefore, the gripping unit can be pivoted proximally to the workpiece which is the gripping target, and the Scott Russell mechanism device including a gripping function suitable for such a gripping application can be provided. Explanation: Scott Russell's mechanism is an exact straight line mechanism, however this mechanism is not so useful for practical purposes as friction and wear of sliding pair is more than that of turning pair. In this mechanism, the slider is replaced by a link traveling . The bridge-type mechanism is one of the most widely used displacement ampliers in micro- scale applications. Therefore, a plurality of variations can be provided to the method of moving the base end part of both of the arm members, and the tip end part of the main arm member can move flexibly.

Therefore, a plurality of variations can be provided to the method of moving the base end part of both of the arm members, and the tip end part of the main arm member can move flexibly. Application: used to connect intersecting shafts . Note that, the substantially parallel angle means that it does not require an accurate parallelism with respect to the sub arm member but includes a slight angle variation, and in the present invention, the substantially parallel angle can be said to be parallel as long as it is within a range of 10 with respect to the axis of the sub arm member in the longitude direction (also in other parts of description a variation range of 10 with respect to the accurate parallelism is included in the meaning of the phrase substantially parallel). This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO). 9.8. It is a four bar mechanism and all the pairs are turning pairs as shown in Fig. The Evans 'grasshopper' linkage is a variant of a Scott Russell linkage which uses a long link to create a large enough arc to approximate a line. In the present invention, the gripping unit is attached to the tip end side of the pivoting unit. wherein either one of the base end part of the sub arm member or the base end part of the main arm member is pivotably coupled to the second linearly-moving unit about the virtual straight line as the pivoting axis thereof. demonstrated by a study of mechanisms already in existence, such as the linkage of a retractable landing gear, computing mechanisms, mechanisms used in an automobile, and the like.
