【正文】 一、課題名稱： 盤磨機(jī)齒輪減速器的設(shè)計(jì) 二、主要技術(shù)指標(biāo)（或基本要求）： 該盤磨機(jī)的主軸轉(zhuǎn)速 n=50r/min，圓錐齒輪傳動(dòng)比 i=4，電動(dòng)機(jī)功率 P=，電動(dòng)機(jī)轉(zhuǎn)速 n1=1500 r/min，每日工作八小時(shí)，傳動(dòng)工作年限為八年，盤磨機(jī)傳動(dòng)不逆轉(zhuǎn)，工作時(shí)有輕微的振動(dòng)，起動(dòng)載荷為名義載荷的 倍，主軸轉(zhuǎn)速允許誤差為177。 三、主要工作內(nèi)容： 這是一個(gè)展開式二級(jí)斜齒圓柱齒輪減速器。在設(shè)計(jì)過程中，要求通過對(duì)兩對(duì)圓柱齒輪傳動(dòng)比的適當(dāng)分配，使該減速器的外形尺寸盡量減小，并通過對(duì)圓柱齒輪的位置設(shè)計(jì)，使各軸的受力情況達(dá)到最合理的狀態(tài)。因此，齒輪及其傳動(dòng)裝置是機(jī)械工業(yè)中一大類重要的基礎(chǔ)件。 然而齒輪傳動(dòng)在使用上也受某些條件的限制：如成本較高（特別是高精度齒輪），使用和維護(hù)的要求高等。 一、 課題研究的主要內(nèi)容： 通過強(qiáng)度計(jì)算和結(jié)構(gòu)設(shè)計(jì)，完成該減速器的總體和傳動(dòng)件的設(shè)計(jì)，并繪制該減速器的總裝圖和零件工作圖。 二、 主要研究（設(shè)計(jì)）方法論述： 在該圓柱齒輪減速器的設(shè)計(jì)中，主要運(yùn)用了類比法、數(shù)據(jù)分析法、設(shè)計(jì)計(jì)算法與圖形相結(jié)合的方法，分析了各齒輪的強(qiáng)度，與總傳動(dòng)比 26 四、設(shè)計(jì)（論文）進(jìn)度安排： 時(shí)間（迄止日期） 工 作 內(nèi) 容 選題 完成畢業(yè)設(shè)計(jì)任務(wù)書、畢業(yè)設(shè)計(jì)開題報(bào)告 收集資料 寫稿：主要設(shè)計(jì)計(jì)算、畫各部件圖及裝配圖 完成初稿 檢查設(shè)計(jì)并請(qǐng)教老師，修改不合理處 定稿、打印 畢業(yè)答辯 五、指導(dǎo)教師意見： 指導(dǎo)教師簽名： 年 月 日 六、系部意見： 系主任簽名： 年 月 日 ag an employment tribunal clai Emloyment tribunals sort out disagreements between employers and employees. You may need to make a claim to an employment tribunal if: you don39。t appealed against the disciplinary action your employer has taken against you. However, if you win your case, the tribunal may reduce any pensation awarded to you as a result of your failure to appeal. Remember that in most cases you must make an application to an employment tribunal within three months of the date when the event you are plaining about happened. If your application is received after this time limit, the tribunal will not usually accept i. If you are worried about how the time limits apply to you If you are being represented by a solicitor at the tribunal, they may ask you to sign an agreement where you pay their fee out of your pensation if you win the case. This is known as a damagesbased agreement. In England and Wales, your solicitor can39。re clear about the terms of the agreement. It might be best to get advice from an experienced adviser, for example, at a Citizens Advice Bureau. To find your nearest CAB, including those that give advice by , click on nearest CAB.

Starting at the ground, conditions have to be very calm winds less than 2 mph, with no precipitation or humidity and limited cloud cover. The balloon, with capsule attached, will move through the lower level of the atmosphere (the troposphere) where our daytoday weather lives. It will climb higher than the tip of Mount Everest ( miles/ kilometers), drifting even higher than the cruising altitude of mercial airliners ( miles/ kilometers) and into the stratosphere. As he crosses the boundary layer (called the tropopause),e can expect a lot of turbulence. We often close ourselves off when traumatic events happen in our lives。我們假裝一切仿佛都不曾發(fā)生，以此試圖忘卻傷痛，可就算隱藏得再好，最終也還是騙不了自己。下面六個(gè)方法有助于你更完滿透徹地敞開心扉。如果我們一味逃避生活中的悲傷，悲傷只會(huì)變得更強(qiáng)烈更真實(shí) —— 悲傷原本只是稍縱即逝的情緒，我們卻固執(zhí)地耿耿于懷 By utilizing our breath we soften our experiences. If we dam them up, our lives will stagnate, but when we keep them flowing, we allow more newness and greater experiences to 。 2. Embrace the unfortable We all know what that twinge of anxiety feels like. We know how fear feels in our bodies: the tension in our necks, the tightness in our stomachs, etc. We can practice leaning into these feelings of disfort and let them show us where we need to ，也都感受過恐懼造成的生理反應(yīng)：脖子僵硬、胃酸翻騰。 The initial impulse is to run away — to try and suppress these feelings by not acknowledging them. When we do this, we close ourselves off to the parts of our lives that we need to experience most. The next time you have this feeling of being truly unfortable, do yourself a favor and lean into the feeling. Act in spite of the fear. 我們的第一反應(yīng)總是逃避 —— 以為否認(rèn)不安情緒的存在就能萬事大吉，可這也恰好妨礙了我們經(jīng)歷最需要的生活體驗(yàn)。 3. Ask your heart what it wants 傾聽內(nèi)心 We’re often confused at the next step to take, making pros and cons lists until our eyes bleed and our brains are sore.
