Application: used to connect intersecting shafts . Scott Russell mechanism developed by John Scott Russell (1808-1882), although already patented in 1803 by watchmaker William Freemantle, gives a theoretically linear motion by using a linkage form with three portions of the links all equal, and a rolling or sliding connection.

With the industrial robot according to Patent Document 1, both of the arm members are rotated (turned) about the screw shaft. A standard Scott Russell straight- mechanism was invented by a French army officer, line mechanism provides an exact straight-line mo- Charles Nicolas Peaucellier, in 1864. A Scott Russell mechanism device pivotably couples a main arm member and a sub arm member to each other, as well as it pivotably couples a joint unit to a tip end part of the main arm member. A rotation unit having a rotor may be coupled to the pivoting member. ASSIGNMENT OF ASSIGNORS INTEREST (SEE DOCUMENT FOR DETAILS). The Scott Russell mechanism device of, 12. A base end part of the main arm member and a base end part of the sub arm member that is on the opposite side from the coupling side of the sub arm member are positioned on the same virtual straight line, and a first distance from the base end part of the main arm member to a coupling position of the main arm member to the sub arm member, a second distance from the coupling position of the main arm member to a tip end part thereof, and a third distance from the base end part of the sub arm member to the coupling position are equal to each other. The length of the link 2 is equal to the distance between points O2 and O4. A dialindicator is a precision measuring tool that uses a needle or pointer to display a measurement on a dial. In the present invention, the joint unit, the rotation unit, and the pivoting unit are coupled to each other in this order. A Scott Russell mechanism device is formed into a boomerang-like shape such that a main arm member coupled to a sub arm member is curved to detour a coupling position. Therefore, even if the main arm member and the sub arm member are not arranged to offset from each other, interference between the arm members at the coupling position of both of the arm members can be subsided, and compared to the conventional device without an offset arrangement, the tip end part of the main arm member can be drawn close to the sub arm member. With the industrial robot according to Patent Document 1, a main arm member (the first arm 31 in Patent Document 1) and a sub arm member (the second arm 32 in Patent Document 1) have fixed thicknesses to secure a desired rigidity (have fixed width and thickness dimensions in cross-sections orthogonal to longitudinal directions of both of the arm members), and thus, as base end parts of both of the arm members (end parts on the screw shaft 21 side in Patent Document 1) are spaced from each other, the arm members interfere with each other at a coupling position of both of the arm members, and a problem arises that the tip end part of the main arm member (end part on the side where the holder H is provided in Patent Document 1) cannot be moved proximally to the sub arm member (a problem arises that the holder H is hard to be moved close at hand to the screw shaft 21 side). Peaucellier linkage can convert an input circular motion to the exact straight line motion. Therefore, compared to the case of coupling the units in an order different from above, the pivoting unit positioned at the farthest tip end can perform the postural displacement in a different range. Perfect straight lines can also be generated using a linkage mechanism. . A Scott Russell linkage is a linkage which translates linear motion through a right angle. The Scott Russel mechanism converts linear motion in one direction to another direction. With the Scott Russell mechanism device, a moving range of the tip end side of the main arm member can be enlarged. Moreover, in the Scott Russell mechanism device according to the present invention, a joint unit may be pivotably coupled to the tip end part of the main arm member. 9.8. These displacement amplifier mechanisms often have a proper amplification ratio capable of large working strokes; however, their low resonant frequency limits their application in high-performance jet dispensers. Therefore, a plurality of variations can be provided to the method of moving the base end part of both of the arm members, resulting in being able to flexibly perform the moving of the tip end part of the main arm member. A pivoting axis of the pivot of the joint unit may be in parallel to an axis of the pivots of the main arm member and the sub arm member at the coupling position. Therefore, the gripping (chucking) flexibly responding to the orientation of a workpiece as a gripping target can be performed by the rotor of the rotation unit of which the amount of the postural displacement is increased, and the Scott Russell mechanism device according to the present invention can suitably be used for the gripping application. Relative motion angles other than 90 degrees are possible by simply rotating the fixed guide. However, a bridge-type mechanism with an external load always works in an energy-inefcient situation due to the storage of strain energy in the exural hinges, which can be validated by the analytical model established in this paper. Moreover, in the Scott Russell mechanism device according to the present invention, the sub arm member may be linearly formed. (Stuart Jonathan) Instructor's solution manual for artificial intelligence : a modern approach (second edition) / Stuart Russell, Peter Norvig. The Scott Russell mechanism device of, 13. Therefore, the application of the Scott Russell mechanism device according to the present invention expands. Jasen Russell tendre la recherche. 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. Therefore, the posture of the joint unit can be controlled freely, and additionally, since the pivot driving unit is provided from the coupling position toward the tip end side of the main arm member, the distance to the joint unit becomes close, and the drive transmission mechanism can be scaled down. Moreover, by providing a pivot driving unit to the main arm member, as well as providing a fourth motor and a drive transmission mechanism unit to the sub arm member, the Scott Russell mechanism device can switch between pivoting the joint unit associatively a change of a coupling angle of the arm members and and pivoting the joint unit by the drive of the fourth motor. Moreover, in the Scott Russell mechanism device according to the present invention, a joint unit may be pivotably coupled to the tip end part of the main arm member. The first exact straight line generating mechanism was invented by a French army officer Charles Nicolas Peaucellier in 1864. Moreover, Patent Document 3 discloses a Scott Russell mechanism applied to a drive structure of a feed arm. Therefore, since the rotor of the rotation unit can rotate independently of the displacement of the tip end part of the main arm member, the displacement amount of the rotor of the rotation unit coupled to the tip end side of the main arm member can be increased, and the application of the Scott Russell mechanism device according to the present invention further expands.

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). In the present invention, the joint unit pivotably coupled to the tip end part of the main arm member can be pivoted in the total of two kinds of manners including the pivot cooperating with the angle change between both of the arm members at the coupling position and the pivot independent to the angle change. A pivoting axis of the pivot of the joint unit may be in parallel to an axis of the pivots of the main arm member and the sub arm member at the coupling position. [0016]. It converts linear motion, to linear motion in a line roughly perpendicular to the input. wherein an axis of the pivot of the pivoting member is in parallel to the pivoting axis of the joint unit, and.
