ength verification. Due to the number of motordriven and the number of degrees of freedom of arms are closely linked, thus reducing the number of motor not only reduce the weight of the arm, but also it will simplify the analysis of the whole system dynamics and kinematics. The transmission of the design has used the flexible shaft, bellows couplings, wrist and two pairs of gear drive. In the choice of material, in order to make the robot weight lighter and the wrist can movements Agile. so selection of light materials, I have designed materials of robot is aluminumcopper alloy of cast aluminum alloy . This robot’s arm has superity of good rigidity, precise transmission and weight lighter. So the design mostly used the standard parts and mon parts, reduced the cost of the design and the production. Key words: Vertical multijoint robot; servo motor ; transmission of gears ; arm 畢業(yè)設(shè)計(jì)(論文)原創(chuàng)性聲明和使用授權(quán)說(shuō)明 原創(chuàng)性聲明 本人鄭重承諾:所呈交的畢業(yè)設(shè)計(jì)(論文),是我個(gè)人在指導(dǎo)教師的指導(dǎo)下進(jìn)行的研究工作及取得的成果。傳 動(dòng)中采用了軟軸、波紋管聯(lián)軸器、傳動(dòng)軸和兩對(duì)齒輪傳動(dòng)。 垂直多關(guān)節(jié)機(jī)器人臂部和手部設(shè)計(jì) 摘要 :由于 關(guān)節(jié)型機(jī)器人具有傳動(dòng)原理簡(jiǎn)單 、 結(jié)構(gòu)湊緊 、 所占空間體積小 、 相對(duì)的工作空間大,還能繞過(guò)基座周?chē)囊恍┱系K物等特點(diǎn)。 由于驅(qū)動(dòng)電機(jī)的個(gè)數(shù)與手臂自由度的個(gè)數(shù)是緊密聯(lián)系的 ,因此減少電機(jī)的數(shù)量不但能減小機(jī)械手臂的重量,而且還會(huì)簡(jiǎn)化整個(gè)系統(tǒng)的動(dòng)力學(xué)與運(yùn)動(dòng)學(xué)的分析。 設(shè)計(jì)中大多采用了標(biāo)準(zhǔn)件和常用件,降低了設(shè)計(jì)和制造的成本。 作 者 簽 名: 日 期: 指導(dǎo)教師簽名: 日 期:
