【正文】 repeat and Criminal law and other laws and regulations repeat。s eighteen years prehensive strictly practice. (a) revised two regulations of the party need of the ICAC guidelines in in 1997 Leaders as members of the Communist Party of China clean politics certain criteria (Trial) based on revised, the promulgation and implementation of January 2021, to strengthen the construction of the contingent of leading cadres play an important role. But with the party to manage the party strictly administering the deepening, has not been able to fully meet the actual needs. Content is too plicated, eight prohibition, 52 are not allowed to hard to remember, and also difficult to put into practice。s leadership, to solve the masses of the people reflect a focus on the problem. The new revision of the code and rule , reflects the party39。 the fourth part on how to grasp the implementation of the two regulations of the party. code and Regulations revised the necessity and revised history of the CPC Central Committee the amendment to the Chinese Communist Party members and leading cadres honest politics several guidelines and Chinese Communist Party discipline and Punishment Regulations column 1 by 2021 to strengthen party laws and regulations focus. Two party regulations revision work lasted a Years, pooling the wisdom of the whole party, ideological consensus, draw historical experience, respect for the wisdom of our predecessors, which reflects the unity of inheritance and innovation。 the second part is the interpretation of the two fundamental principles of the revision of laws and regulations in the party。 (英文版 ) Two regulations promulgated for implementation is in the party in power for a long time and the rule of law conditions, the implementation of prehensive strictly strategic plan, implementation in accordance with the rules and discipline to manage the party, strengthen innerparty supervision of major initiatives. The two regulations supporting each other, the code adhere to a positive advocate, focusing on morality is of Party members and Party leading cadres can see, enough to get a high standard。根據(jù)傳動扭矩、轉(zhuǎn)速 ,選擇具體型號 (尺寸 ) 22. 氈圈密封槽為何做成梯形槽? 答 : 矩形斷面的毛氈圈被安裝在梯形槽內(nèi) ,使毛氈圈對軸產(chǎn)生一定的壓力而起到密封作用 23. 定位銷的作用是什么?其位 置如何確定 ? 答 : 定位銷的作用就是便于箱體和箱蓋連接時定位 , 并可傳遞不大的載荷。 Z2=iZ 1。大的( 2040) 另外,根據(jù)中心距確定齒數(shù)。 閉式軟齒面?zhèn)鲃樱涸诒WC齒面接觸疲勞強度前提下,滿足齒根彎曲疲勞強度;正軟齒面齒輪的熱處理方法 ; 火、調(diào)制、滲氮、滲碳、碳氮共滲 20. 你 所設(shè)計的齒輪減速器的模數(shù) m 和齒數(shù) z 是如何確定的? m—— 首 先,根據(jù)傳動比確定齒數(shù)。閉式齒輪傳動中,通常以保證齒面接觸疲勞強度為主 簡述齒輪零件工作圖的設(shè)計要點 ; . .。應(yīng)靠近輪轂裝入側(cè)軸端端部 , 以利于裝配時輪轂的鍵槽容易對準軸上的鍵槽。 答案;看他安裝零部件的精度要求 ; 16. 軸上鍵槽的位置與長度如何確定?你所設(shè)計的鍵槽是如何加 工的? 答 : 平鍵的剖面尺寸根據(jù)相應(yīng)軸段的直徑確定 , 鍵的長度應(yīng)比軸段長度短。按電機的額定功率計算; 我們按額定的功率計算可以得到他的最大轉(zhuǎn)矩, ……. , 說明軸上零件的定位與固定方法。所以不能太大也不能太小。 22..第一是防塵、第二是預(yù)防油脂外漏 軸的危險截面在哪里? 你所選擇的軸的材料是哪一種?為何這樣選擇?采用哪種熱處理方法?為什么? 設(shè)計軸時,對軸肩(或軸環(huán))的高度及圓角半徑有什么要求。 簡述滾動軸承內(nèi)外圈的配合特點及標注特點?軸承采用脂潤滑時為什么要采用擋油環(huán)? 6405 間是配合和過癮配合 基孔制配合 根據(jù)所設(shè)計的軸的軸徑的大小 , 并查表進行初選 , 最后在初步設(shè)計完成后對軸進行彎扭合成強度校核時看軸的強度是否滿足需要 , 并確定軸承的型號 。 應(yīng)標注的尺寸有: 寸 裝配圖的作用是 :制定裝配工藝規(guī)程 進行裝配、檢驗、安裝及維修的技術(shù)要求 。內(nèi)任意的平面 。 你所設(shè)計的依據(jù)是什么???、 為了提高生產(chǎn)效率 ..減輕企業(yè)的資金問題,減輕工人的勞動強度等等 你設(shè)計的 設(shè)備的工作原理和用途 。 通過 操作 控制面板 輸 到 I/O 接口在到 控制器在轉(zhuǎn)送到伺服單元找到伺服電機,電機帶動絲桿轉(zhuǎn)動 …完成需要的動作 …. 將普通立式銑床改造成經(jīng)濟型數(shù)控銑床,用于加工中小型零件的平面、成型表面(如任意圓弧、凸輪的曲面)及 45176。 裝配圖上應(yīng)標注哪幾類尺寸?就你所繪的圖紙進行說明。 3. 說明你選擇的軸承類型、型號和選擇依據(jù)。 若不能滿足 , 則可選用相同內(nèi)徑的圓錐滾子軸承 答案; 防止箱體內(nèi)飛濺的油 進入軸承破壞它的脂潤滑 , 是 防止軸承轉(zhuǎn)動溫度升高,潤滑脂融化流失 。 答案;是最小的軸那一節(jié) ; 45 號鋼; 硫磷含量低 力學性能優(yōu)于碳素結(jié)構(gòu)鋼 ; 有較好的機械性能 ,加工性能和熱處理性能 ,且價格比較便宜 .( ) ; 軸壞; 圓角半徑有 .不能太大也不能太小 正火并回火 … .軸肩圓角半徑過小則不能充 分發(fā)揮設(shè)置圓弧減少應(yīng)力集中的目的;軸肩圓角半徑過大則可能影響在此安裝的零件的裝配位置,使其不能緊靠軸肩。 ; 就圖紙上某一公差配合代號說明其含義并查表求出具體數(shù)值? ; 7. 潤滑 和 密封問題; 滋潤滑, ……….. 8. 電路圖原理的 問題; ; 齒輪 .軸 45 號鋼 .其他的用 HT150 ; , 電動機的額定功率 與輸出功率有何不同?傳動件按哪個功率設(shè)計?為什么? 答案:根據(jù)電機的轉(zhuǎn)矩 ,一個是電機的最大功率,一個是電機的實際輸出功率。 軸上零件的定位與固定方法 ; 鍵(平鍵、花鍵、月牙鍵也叫半圓鍵)、銷 . 利用軸肩 軸套 平鍵 花鍵 卡簧等 ;; 移動零件的限位問題 ; 。鍵槽不要太靠近軸肩處 , 以避免由于鍵槽加重過度圓角處的應(yīng)力集中。采用盤銑刀加工 答案;根據(jù)機械設(shè)計手冊,長度是根據(jù) 鍵 的標準選型表 ?為何這樣選擇? 采用哪種熱處理方法 ?為什么? 采用哪種熱處理方法 ;;; 正火或正火并回火 , ? 簡述齒輪零件工作圖的設(shè)計要點? 答案; 齒輪傳動中輪齒的失效形式 有輪齒折斷、齒面磨損、齒面點蝕、和齒面膠合四種 設(shè)計準則 ;;; 通常只按保證齒根彎曲疲勞強度及保證齒面接觸疲勞強度兩準則進行計算。 4 形位公差的標注 5 技術(shù)要求 6 標題欄 . 19. 試述獲得軟齒面齒輪的熱處理方法及軟齒面閉式齒輪傳動的設(shè)計準則。小齒輪齒數(shù)應(yīng)該大于最小齒數(shù) 17(1720)齒。綜合考慮上述兩項內(nèi)容,最終確定齒輪的齒數(shù)。 21. 你是根據(jù)什么選擇聯(lián)軸器的 ? 根據(jù)傳動的平穩(wěn)性、對中性要求 ,選擇聯(lián)軸器的種類。 一般在箱體的斜對角位置 , 不能設(shè)計成對稱位置。 rule around the party discipline, disciplinary ruler requirements, listed as negative list, focusing on vertical gauge, draw the party anizations and Party members do not touch the bottom line . Here, the main from four square face two party rules of interpretation: the first part introduces two party Revised regulations the necessity and the revision process。 the third part introduces two party regulations modified the main changes and needs to grasp several key problems。 follow the correct direction, grasp the limited goals, adhere to the party39。s 18 and the eighth session of the third, the spirit of the fourth plenary session, reflecting the experience of studying and implementing the General Secretary Xi Jinping series of important speech, reflects the party39。 the second is concisely positive advocated by the lack of prohibited provisions excessive, no autonomy requirements。 the fourth is to clean the theme is not prominent, not for the existing problems, and is narrow, only needle of countylevel leading cadres above. rule is in 1997 Chinese Communist Party disciplinary cases (Trial) based on revision, in December 2021 the promulgation and implementation, to strengthen the construction of the party play very important role. Along with the development of the situation, which many provisions have been unable to fully meet the prehensive strictly administering the practice needs. One is Ji law, more than half of the provisions and crim
