assembly error is one of the most important components influencing assembly quality 摘要機(jī)器人裝配系統(tǒng)中,裝配誤差是影響裝配質(zhì)量的重要因素。
In conclusion, this paper focuses on the modeling technology of assembly in virtual manufacturing environme nts, analyzes the cause of assembly error and gives its revise arithmetic, and solves the problems of low display speed and real time by the entity modeling method 論文重點(diǎn)研究了虛擬制造環(huán)境的裝配建模技術(shù),分析了裝配誤差的產(chǎn)生及校正方法,解決了采用直接實(shí)體造型法顯示速度慢,實(shí)時(shí)性差的問(wèn)題,具有較強(qiáng)的實(shí)用性。
First, the basic theory of static load sharing mechanism has been presented, mainly including manufacturing and assembly error of each gear component's axis and each bearing's axis, gear size ( tooth thickness ) errors, simultaneous error of middle two-tooth . the formula of equivalent mesh error has been deduced, the load sharing coefficient has been computed . second, the influences of each error on the static load sharing coefficient have been discussed 首先,從靜力學(xué)的角度研究了星型齒輪系統(tǒng)均載的基本原理;確定了影響齒輪系統(tǒng)均載特性的制造和安裝誤差,主要包括:各個(gè)齒輪構(gòu)件的中心軸線制造和安裝誤差、軸承中心軸線的制造和安裝誤差、齒厚偏差、雙聯(lián)星輪同時(shí)嚙合線誤差;推導(dǎo)了這些誤差的當(dāng)量嚙合誤差的計(jì)算公式,分析了系統(tǒng)的均載特性。
Nevertheless, the widely existed overconstraints in the mechanisms will make the quality of the mechanisms very sensitive to the inevitable manufacturing, assembly errors ( especially, the errors resulted from the shape and position between kinematic pair elements and their axes ) . at the same time, because the internal and external uncertain factors such as non-plane characteristic of dynamic parameters of links ( such as mass distribution, inertia forces, etc . ), bending and twist of links, and the changes of environment and operating condition are inevitable, they will form the disturbance to planar constraints and make them possess the characteristic of " uncertain " 但是,平面連桿機(jī)構(gòu)中廣泛存在的過(guò)約束,造成機(jī)構(gòu)對(duì)制造、安裝誤差特別是運(yùn)動(dòng)副元素的形位誤差十分敏感;同時(shí),由于不可避免的內(nèi)部和外部不確定因素的影響,常常會(huì)造成機(jī)構(gòu)運(yùn)動(dòng)的“障礙”及系統(tǒng)中某些構(gòu)件的變形和運(yùn)動(dòng)副中的附加動(dòng)載荷,引起機(jī)械的振動(dòng)、沖擊、噪聲等而導(dǎo)致機(jī)械的效率和工作性能的降低。
