And choose a best scheme of the design and calculation. 3, the pression block molding machine drive the main part of the movement design and structure design Drive the main part of the movement design and structure design mainly includes the gear drive, tape drive, shaft, bearing, key, such as casing design. Gear drive and belt drive the main design model and design the way of transmission and relevant selection of design parameters are determined, to determine the optimal way of rotation and the best parameters. Main design its paragraphs diameter size and the shape of the design, the bearing is mainly the design and calculation of the selection of parameters and the key to select the appropriate bearing and key, the design of the box body including the transmission of lubrication and sealing design includes the design of other parameters of the. Finally ,finish the related design paper writing and related engineering drawing of the graph. Key words: technological design。 principle design。 The main transmission part design 桂林電子科技大學(xué)畢業(yè)設(shè)計(jì)報(bào)告紙 I 目 錄 引言 ...................................................... 1 1 沖壓型壓縮營(yíng)養(yǎng)缽成型機(jī)原理設(shè)計(jì) ........................... 3 沖壓型壓縮營(yíng)養(yǎng)缽成型機(jī)工藝分析 ..................................... 3 沖壓型壓縮營(yíng)養(yǎng)缽成型機(jī)原理設(shè)計(jì) ..................................... 3 沖壓型壓縮營(yíng)養(yǎng)缽成型機(jī)工作原理 ................................. 3 沖壓型壓縮營(yíng)養(yǎng)缽成型機(jī)原理圖 ................................... 4 對(duì)原理圖中機(jī)構(gòu)進(jìn)行數(shù)據(jù)分析 ..................................... 5 沖壓型壓縮營(yíng)養(yǎng)缽成型機(jī)主要參數(shù)和主要傳動(dòng)部分的確定 ................. 6 沖壓型壓縮營(yíng)養(yǎng)缽成型機(jī)主要參數(shù)的確定 ............................ 6 沖壓型壓縮營(yíng)養(yǎng)缽成型機(jī)主要傳動(dòng)部分和傳動(dòng)比的確定 ............... 8 2 沖壓型壓縮營(yíng)養(yǎng)缽成型機(jī)帶輪的設(shè)計(jì) ........................ 10 設(shè)計(jì)計(jì)算 .......................................................... 10 1 確定計(jì)算功率 ...................................................... 10 2 選擇 V 帶的帶型 .................................................... 10 3 設(shè)計(jì)帶輪的基準(zhǔn)直徑并驗(yàn)算帶速 ...................................... 11 4 確定 V 的中心距 a 和基準(zhǔn)長(zhǎng)度 L ....................................... 11 5 驗(yàn) 算小帶輪上的最小包角 ............................................ 11 6 計(jì)算帶的根數(shù) ...................................................... 11 7 計(jì)算單根帶的拉力的最小值 .......................................... 12 8 計(jì)算軸壓力 ........................................................ 12 9 帶輪的結(jié)構(gòu)設(shè)計(jì) .................................................... 12 3 一級(jí)減速齒輪設(shè)計(jì) ....................................... 13 一級(jí)圓柱直齒輪減速優(yōu)點(diǎn)和傳動(dòng)功率計(jì)算 ............................... 13 一級(jí)圓柱齒輪減速優(yōu)缺點(diǎn) ........................................ 13 傳動(dòng)功率的計(jì)算 ................................................ 13 漸開(kāi)線圓柱直齒輪材料、精度等級(jí)和齒數(shù)的選取 ........................ 13 漸開(kāi)線圓柱直齒輪材料的選取 .................................... 13 漸開(kāi)線圓柱直齒輪精度等級(jí)的選取 ................................ 14 齒數(shù)的選擇 .................................................... 14 按齒面接觸強(qiáng)度計(jì)算 ................................................ 14 確定公式中各值 .................................................. 14 計(jì)算 .......................................................... 15 按齒根彎曲強(qiáng)度設(shè)計(jì) ............................................ 15 結(jié)構(gòu)和幾何尺寸計(jì)算 ............................................ 16 桂林電子科技大學(xué)畢業(yè)設(shè)計(jì)報(bào)告紙 II 4 換向錐齒輪設(shè)計(jì) ......................................... 17 強(qiáng)度計(jì)算 .......................................................... 17 接觸強(qiáng)度初定主要尺寸 .......................................... 17 接觸疲勞強(qiáng)度校核計(jì)算 .......................................... 17 幾何尺寸和結(jié)構(gòu)設(shè)計(jì) ....................
