螺旋張緊或液壓張緊皮帶機的打滑 : 使用螺旋張緊或液壓張緊的皮帶運輸機出現(xiàn)打滑時可調(diào)整張緊行程來增大張緊力。跑偏的原因有多種,需根據(jù)不同的原因區(qū)別處理。 ⑵ 安裝調(diào)心托輥組 調(diào)心托輥組有多種類型如中間轉(zhuǎn)軸式、四連桿式、立輥式等其原理是采用阻擋或托輥在水平面內(nèi) 方向轉(zhuǎn)動阻擋或產(chǎn)生橫向推力使皮帶自動向心達到調(diào)整皮帶跑偏的目的。因為一條皮帶輸送機至少有 2到 5個滾筒,所有滾筒的安裝位置必須垂直于皮帶輸送機長度方向的中心線,若偏斜過大必然發(fā)生跑偏。調(diào)整方法。使用螺旋張緊或液壓油缸張緊時,張緊滾筒的兩個軸承座應(yīng)當同時平移,以保證滾筒軸線與皮帶縱向方向垂直。相對高度 越低,物料的水平速度分量越大,對下層皮帶的側(cè)向沖擊也越大,同時物料也很難居中。在受空間限制的移動散料輸送機械的上下漏斗、導(dǎo)料槽等件的形式與尺寸更應(yīng)認真考慮。調(diào)整時要仔細觀察皮帶運動方向與跑偏趨勢的關(guān)系,逐個進行調(diào)整。原動機為 Y112M4三相異步電動機,其額定功率 P=11kW,滿載轉(zhuǎn)速 n1=1460r/min,從動輪 轉(zhuǎn)速 n2=400r/ min,中心距 a≤ 550mm。 第 31 頁 共 53 頁 v 11 2 5 0 1 4 6 0 196 0 1 0 0 0 6 0 1 0 0 0ddnv ? ? ??? ? ???m/s [3](式 43) 式中 : dd1? 小帶輪基準直徑, mm n1 ? 轉(zhuǎn)速, r/min 在 5~ 25m/s范圍內(nèi),帶速合適。 第 34 頁 共 53 頁 0100 1 0 0 1 . 1 1 3 . 2 6812 . 1 0 . 9 4 0 . 9AKPA P K K????? ? ?mm [3](式 47) 式中: KA工作系數(shù); P0基本額定功率, KW; K? 包角修正系數(shù); K? 傳動布置系數(shù); P功率, KW。 主軸和一般磨頭帶輪( n≤ 600010000r/min) 。 第 38 頁 共 53 頁 平帶輪直徑、結(jié)構(gòu)形式和輻板厚度: 注:本表單位是 mm。 2 25 177。 2 40 177。 2 63 177。 3 80 177。 3 100 177。 3 125 177。 4 160 177。 4 200 177。 4 250 177。 通過帶式輸送機傳動裝置的設(shè)計 ,了解了帶式輸送機傳動裝置的原理以及其結(jié)構(gòu)。 第 42 頁 共 53 頁 致謝 在指導(dǎo)老師的帶領(lǐng)下,我比較圓滿的完成了畢業(yè)設(shè)計任務(wù)。 二、 本課題設(shè)計的關(guān)鍵問題及解決問題的思路 《皮帶機概論》需要同過查找資料與理解內(nèi)容 第 46 頁 共 53 頁 三、 本課題設(shè)計綱要(或思路) 從帶式輸送 機傳動裝置的設(shè)計,我學(xué)到了機械設(shè)計的思想 以最少的成本達到最好的目的 ,以最簡單的結(jié)構(gòu)達到所需的功能。t agree with the disciplinary action your employer has taken against you your employer dismisses you and you think that you have been dismissed unfairly.

We try to deflect the hurt and pain by pretending it doesn’t exist, but although we can try this all we want, in the end, we can’t hide from ourselves. We need to learn to open our hearts to the potentials of life and let the world soften us. 生活發(fā)生不幸時,我們常常會關(guān)上心門;世界不僅沒能慰藉我們,反倒使我們更加消沉。 Whenever a painful situation arises in your life, try to embrace it 第 51 頁 共 53 頁 instead of running away or trying to mask the hurt. When the sadness strikes, take a deep breath and lean into it. When we run away from sadness that’s unfolding in our lives, it gets stronger and more real. We take an emotion that’s fleeting and make it a solid event, instead of something that passes through us. 當生活中出現(xiàn)痛苦的事情時,別再逃跑或隱藏痛苦,試著擁抱它吧;當悲傷來襲時,試著深呼吸,然后直面它。其實,我們有能力面對這些痛苦的感受,從中領(lǐng)悟到出路。與 第 52 頁 共 53 頁 其一味顧慮重重,不如從局外人的角度看待決策之事。t.
