機械式機構(gòu)大約到19世紀末達到成熟，現(xiàn)在幾乎所有使用的機構(gòu)（自動裝）在其歷史上都能見到。
In addition, the
mechanical institutions reached maturity by the end of nineteenth
Century. Now almost all the institutions (automatic devices) can be seen
in its history. （2）力作用線 (2) force action line
為了只觀地表示力在機械機構(gòu)中怎樣傳遞下去的狀態(tài)，將力看作猶如在構(gòu)件中留動的樣子，描繪在草案圖的機械中。表示這個力“流動”的線，在設(shè)計考察中起著重要作用。例如：產(chǎn)生某種動作的機械，如果處于靜態(tài)平衡，難么力作用線在整體系統(tǒng)中封閉。如果力線不封閉，或者該機械正題開始加速運動或者在空間分解。轉(zhuǎn)動力矩的作用現(xiàn)也同樣。
In order to see only the state of the transmission of the surface force
in the mechanical mechanism, the force is regarded as if it is left in
the component, depicted in the machinery of the draft map. The line that
indicates the force "flow" plays an important role in design
investigation. For example, a machine that produces certain action, if
it's in a static equilibrium, the hard force line will be closed in the
whole system. If the force line is not closed, or the mechanical topic
begins to accelerate motion or decompose in space. The effect of the
moment of rotation is the same. （3）平衡 (3) balance
僅對于由重力產(chǎn)生的力，其力線不封閉。這里，重力所產(chǎn)生的逆轉(zhuǎn)力矩成為額外難題。機械處于靜態(tài)時出現(xiàn)逆轉(zhuǎn)的部位是機械型線 流水槽模具 景觀石 檢查井鋼模具 保定通風(fēng)管道 隔離墩模具 保定保潔公司的根本缺陷之處。不要制作頭重腳輕或左右重力不能保持平衡的物體。這是應(yīng)為這樣的物體受到一點水平向外就會翻轉(zhuǎn)的緣故。此外，把握機械的大致重量，穩(wěn)心的位置也是非常重要的。特別是，如果重心水平方向位于安裝地腳之外，則會失去自身平衡，是機器出現(xiàn)非正常狀態(tài)，這一點要給以注意。
The force line is not closed only for the force generated by gravity.
Here, the reverse torque generated by gravity becomes an additional
problem. When machinery is in static state, the reverse part is the
fundamental defect of machinery. Don't make top-heavy or gravity balance
objects. This is the reason why such an object will be turned outward
at a certain level. In addition, it is very important to grasp the
approximate weight of machine and the location of the center of
stability. In particular, if the horizontal direction of gravity is
located outside the installation ground, it will lose its balance, which
is the abnormal state of the machine
