crank link 中文意思是什麼
crank link
解釋
曲柄連桿-
This drilling adopts crank connecting link and walking beam percussion mechanism, which make the drilling possess two percussive functions, normal drilling takes connecting link impact as main mode, when encountering special situation and the connecting link impact can not drill, it can transform into hoisting impact, the stroke length can be modulated, it realizes automatic percussive drilling due to continuous operating of connecting link percussive mechanism, these can enhance drilling efficiency and relieve labor intensity ; it adopts pumping reverse circulation to drain slag, which not only resolves the drilling difficulty in special stratum such as pebble and gravel stratum and hard stratum, but also resolves the problem that the percussive drill ' s efficiency is low ; it adopts spur gear differential mechanism as double cylinders lazy tongs of main hoist, which not only ensures the balance state of drilling tool, but also reduces the mechanical design, and reduces the cost ; the bottom plate traveling motion of this drilling machine adopts walking type ; the drilling tower adopts hydraulic pressure uprising, and reduces the assistant operating time
該鉆機採用曲柄連桿、游梁式沖擊機構，使鉆機具有兩種沖擊功能;正常鉆進以連桿沖擊為主，遇到特殊情況，用連桿沖擊不能鉆進時，可轉為卷揚沖擊，沖程可調，因連桿沖擊機構連續工作，所以實現了自動沖擊鉆進，可提高鉆進效率，減輕勞動強度;採用泵吸反循環的方式排渣，既能有效解決卵礫石地層、堅硬地層等特殊地層鉆進的困難，又很好地解決了沖擊鉆機效率低下的問題;採用直齒圓柱齒輪差速機構作為主卷揚的雙筒同步機構，既保證了鉆具處于平衡狀態，又大大簡化了該機構設計，降低了成本;該鉆機底盤行走移位採用步履式;鉆塔採用液壓起立，減少了輔助作業時間。 -

It is believed, through analyzing, that the ratio radius of the crank to length of the link is importantly influential in the reed motion about 4 - linkage beating - up mechanism, and, that the specific property of slow motion at back center is mainly decided by the second 4 - linkage mechanism on the 6 - linkage beating - up mechanism
對連桿機構運動分析認為：四連桿打緯機構的曲柄半徑與牽手長度之比是影響筘座運動的重要因素，六連桿打緯機構的后心運動緩慢特性主要由第二個四連桿機構決定。 -
The existence of a c - c ( crank - crank ) type of geared five - bar linkages linked with the ground link, the classification and the range of gear ratio and phase angle in the fully rotatability of geared five - bar linkages were mainly studied in this dissertation
本論文主要研究了齒輪?五桿機構中與機架相連的兩連架桿的雙曲柄的存在條件、齒輪?五桿機構的分類以及在每一分類中齒輪?五桿機構能夠整周轉動時其相位角和傳動比的范圍。 -
The main content of this thesis includes the following parts : ( 1 ) in chapter 2, the conditions of link lengths are derived for the side bars to rotate as cranks. two types of cranks are defined and then five - bar linkages are divided into four types, i. e. the full double - crank linkage, the double quasi - crank linkage and the double rocker linkage, and the crank - rocker linkage. the rotational ranges of the two side links for each type of the mechanism are analyzed, and the corresponding numerical algorithm is developed
本文主要做了以下幾方面的工作： （ 1 ）在第二章中，先導出五桿機構兩連架桿可整周轉動的桿長條件，並根據曲柄的存在情況，對五桿機構進行分類，即把五桿機構分成全曲柄機構、雙準曲柄機構、雙搖桿機構和準曲柄-搖桿機構四種類型。 -
Adopt crank shift, link mechanism, and gear drive to improve work efficiency
採用曲柄、連桿機構，齒輪傳動，省力是提高工作效率的利器。 -
The dimensions of this hybrid mechanism is " from the result of the example in chapter 4. a rotary encoder is used to gather the position signal of the crank, according to which micro - computer control the rotation of the setup motor assembled with the other side link in order to adjust the position of this side link. only if we turn arbitrarily the crank connected to the rotary encoder, a given path is generated precisely
根據第四章中優化綜合得出的結果，製作五桿機構模型，採用一角度傳感器測得作主運動的曲柄的位置參數，由單片機根據此參數來控制與另一曲柄相連的步進電機的轉動，使連桿點精確再現給定的軌跡。
