Further, Patent Document 5 discloses a Scott Russell mechanism in a modified example where the coupling between the main arm member and the sub arm member is in a crank shape, the Scott Russell mechanism applied to a transport device. The dynamic equations of a micro-positioning Scott-Russell (SR) mechanism associated with . The first exact straight line generating mechanism was invented by a French army officer Charles Nicolas Peaucellier in 1864. Ce bouton affiche le type de recherche actuellement slectionn. Thus, when the coupling angle is changed so that a base end part of the main arm member and a base end part of the sub arm member are most separated from each other, a tip end part of the main arm member can be moved close to right beside the base end part of the sub arm member. Here is a sampling of five herbs that have demonstrated potential immune support benefits: 1. wherein a pivoting axis of the pivot of the joint unit is in parallel to an axis of the pivots of the main arm member and the sub arm member at the coupling position, and. Furthermore, Patent Document 4 discloses a Scott . A Scott Russell mechanism is a mechanism where a linear main arm member is pivotably coupled to a sub arm member, a distance from a base end part of the main arm member to a coupling position thereof, a distance from the coupling position of the main arm member to a tip end part thereof, and a distance from a coupling position of the sub arm member to a base end part thereof are all equal to each other, and in a case where a coupling angle between both of the arm members is changed, the tip end part of the main arm member linearly moves along a straight line connecting the tip end part of the main arm member and the based end part of the sub arm member. In the present invention, the joint unit, the rotation unit, and the pivoting unit are coupled to each other in this order. A straight-line mechanism causes a point to travel in a straight line, or in a nearly straight line, without being guided by a plane surface. These mechanisms are governed by Kinematics the study of geometry and motion. 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. Relative motion angles other than 90 degrees are possible by simply rotating the fixed guide. The bridge-type mechanism is one of the most widely used displacement ampliers in micro- scale applications. In this mechanism, the slider is replaced by a link traveling . Library of Congress Cataloging-in-Publication Data Russell, Stuart J. A Scott Russell linkage is a linkage which translates linear motion through a right angle. a sub arm member pivotably coupled to the main arm member; and. In each of the applets, drag the sliders to change the shape of the path of the free point to obtain the longest possible straight path. Furthermore, in the Scott Russell mechanism device according to the present invention, the angle changer may also have 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. 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. Highlight matches. This mechanism has eight members and six joints.if(typeof ez_ad_units!='undefined'){ez_ad_units.push([[250,250],'brighthubengineering_com-large-mobile-banner-2','ezslot_15',179,'0','0'])};__ez_fad_position('div-gpt-ad-brighthubengineering_com-large-mobile-banner-2-0'); The complexity of the mechanisms to generate exact straight lines can be reduced by introduction of one or more slider crank linkages. Thus, the tip end part of the main arm member can be drawn more to the base end part of the sub arm member. wherein the main arm member and the sub arm member are pivotable about the virtual straight line as a pivoting axis thereof, the angle changer including: 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, and, wherein either one of the base end part of the main arm member or the base end part of the sub arm member is pivotably coupled to the first linearly-moving unit about the virtual straight line as the pivoting axis thereof, and. wherein 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 present invention is made in view of the above situations, and aims to provide a Scott Russell mechanism device that is capable of drawing close to a tip end part of a main arm member proximally to a sub arm member by forming the main arm member into a boomerang-like shape without arranging both of the arm members offset from each other.
