【摘要】：工程實(shí)際中的很多場合,都需要用到往復(fù)轉(zhuǎn)動。隨著現(xiàn)代工業(yè)自動化水平的提高以及產(chǎn)品品種多樣化發(fā)展的趨勢,對實(shí)現(xiàn)往復(fù)運(yùn)動的機(jī)構(gòu)提出了新的要求。首先要求其自動化程度高便于控制,同時(shí)要求往復(fù)運(yùn)動的速度和動程均可控以適應(yīng)產(chǎn)品多樣化的需要。 文章內(nèi)容主要有如下三個(gè)部分： 第一部分,提出了采用雙伺服驅(qū)動差動輪系將單向回轉(zhuǎn)運(yùn)動合成為可控往復(fù)輸出運(yùn)動,文中通過理論推導(dǎo)和運(yùn)動仿真證明了其可行性,并在此基礎(chǔ)上提出三種可實(shí)現(xiàn)方案,對應(yīng)推導(dǎo)出了三種方案的等效轉(zhuǎn)動慣量的計(jì)算式,為在工程實(shí)際中的具體應(yīng)用選擇何種方案提供了參考。 第二部分,對非圓行星輪系和非圓差動輪系將電機(jī)的單向回轉(zhuǎn)輸入轉(zhuǎn)化為往復(fù)轉(zhuǎn)動輸出進(jìn)行了相關(guān)研究,提出了非圓齒輪的節(jié)曲線的設(shè)計(jì)方法并給出了幾個(gè)非圓齒輪節(jié)曲線設(shè)計(jì)的相關(guān)實(shí)例。 第三部分,將具有電子凸輪功能的伺服驅(qū)動輪系應(yīng)用于工程實(shí)際中,同時(shí)為了使其具有更好的動態(tài)性能,對電子凸輪曲線進(jìn)行了優(yōu)化設(shè)計(jì),并進(jìn)一步對差動輪系伺服電機(jī)的驅(qū)動方式進(jìn)行選擇,采用優(yōu)化設(shè)計(jì)的方法得出伺服電機(jī)的輸入曲線,并使其具有較好的動態(tài)性能。
[Abstract]:In engineering practice, many occasions need to use reciprocating rotation. With the improvement of modern industrial automation level and the trend of diversification of product varieties, A new requirement is put forward for the mechanism to realize reciprocating motion. Firstly, it is required that its high degree of automation be easy to control, and at the same time, the speed and range of reciprocating motion can be controlled to meet the needs of diversification of products. The main contents of the article are as follows:. In the first part, the unidirectional rotary motion is synthesized into controllable reciprocating output motion by double servo drive differential gear train. The feasibility is proved by theoretical derivation and motion simulation. On the basis of this, three feasible schemes are put forward. The equivalent moment of inertia of the three schemes is derived, which provides a reference for the practical application of the three schemes. In the second part, the non-circular planetary gear train and the non-circular differential gear train are studied to transform the one-way rotary input of the motor into the reciprocating output. The design method of pitch curve of non-circular gear is put forward and some examples of non-circular gear pitch curve design are given. In the third part, the servo driving gear train with electronic cam function is applied to engineering practice, and in order to make it have better dynamic performance, the curve of electronic cam is optimized. Furthermore, the drive mode of the servo motor of differential gear train is selected, and the input curve of the servo motor is obtained by using the method of optimization design, and the servo motor has better dynamic performance.
