When a connection is desired which can be disassembled without destructing the parts assembled and which is strong enough to resist both external tensile load and shear load, or a bination of these, then the simple bolted joint using hardened washers is a good solution. 當(dāng)想要一個(gè)可以被拆開又不破壞被聯(lián)接零件的聯(lián)接時(shí)，而且這個(gè)聯(lián)接又要有足夠的強(qiáng)度以承受外拉力和剪力或這兩種力的結(jié)合，使用淬火墊圈的簡(jiǎn)單螺栓聯(lián)結(jié)是一個(gè)很好的方法。如果 構(gòu)件中的某一構(gòu)件仍保持固定而使任一運(yùn)動(dòng)到達(dá)一新的位置而不會(huì)使其他各個(gè)構(gòu)件運(yùn)動(dòng)到一個(gè)確定的預(yù)期的位置上的話，則該系統(tǒng)裝置是一個(gè)非約束運(yùn)動(dòng)鏈。 it implies smooth operation, in which a maximum force ponent is available to produce a force or torque in an output member. Although the resulting output force or torque is not only a function of the geometry of the linkage, but is generally the result of dynamic or inertia force, which are often several times as large as the static force. For the analysis of lowspeed operations or for an easily obtainable index of how any mechanism might run, the concept of the transmission angle is extremely useful. During the motion of a mechanism, the transmission angle changes in value. A transmission angle of 0 degree may occur at a specific position, on which the output link will not move regardless of how large a force is applied to the input link. In fact, due to friction in the joints, the general rule of thumb, is to design mechanisms with transmission angle of larger than a specified value. Matrixbased definitions have been developed which measure the ability of a linkage to transmit motion. The value of a determinant (which contains derivatives of output motion variables with respect to an input motion variable for a given linkage geometry[2] ) is a measure of the movability of the linkage in a particular position. （ 除了具備關(guān)于構(gòu)件回轉(zhuǎn)范圍的知識(shí)之外，還要具備如何使機(jī)構(gòu)在制造之前就能 “ 運(yùn)轉(zhuǎn) ”的良好措施，那將是很有用的。 ） 6. A kinematician defined kinematics as the study of the motion of mechanisms and methods of creating them. The first part of this definition deals with kinematic analysis. Given a certain mechanism, the motion characteristics of its ponents will be determined by kinematic analysis. The statement of the tasks of analysis contains all principal dimensions of the mechanism, the interconnections of its links, and the specification of the input motion or method of actuation. The objective is to find the displacements, velocities, accelerations, shock or jerk (second acceleration), and perhaps higher accelerations of the various members, as well as the paths described and motions performed by certain elements. In short, in kinematic analysis we det
