By comparing,3(II)Planetary gear reducer is selected . The design of the main elements to be completed: 1. Determine the transmission scheme Transmission scheme for the transmission ratio, including the identification and determination of transmission type. 2. Design calculations Transmission structure of each level of design and calculation, generally include: transmission ratio of the distribution, kinematics and dynamics calculation of transmission, transmission parts of the design, calculation and check of the design axis, the axis of the selection and calculation, and calculation of key connectivity options , cabinet design, lubrication and sealing selection and transmission of attachment descriptions. 3. Assembly drawing and the design of the part drawing. Through this design, known planetary gear reducer has a compact, small, compact and feature transmission efficiency, but because of planetary gear reducer transmission ratio, torque to gear structure than other small, self-locking planetary gear reducer Great angle and poor only retreat is not suitable for starting. 朗讀 顯示對應的拉丁字符的拼音 ? 字典 Keywords: Planetary Gear Reducer Design calculations Transmission scheme Signature of Supervisor: 目錄 摘要………………………………………………………………………………………I ABSTRACT………………………………………………………………………………II 1 緒論 1.1 課題研究的背景和意義……………………………………………………………1 1.2 行星齒輪減速器研究現(xiàn)狀及發(fā)展動態(tài)……………………………………………1 1.3 本文研究的主要內容………………………………………………………………4 2 3Z（II）型行星齒輪減速器裝置設計 2.1 已知條件……………………………………………………………………………5 2.2 設計計算……………………………………………………………………………5 2.2.1選取行星齒輪傳動的傳動類型和傳動簡圖……………………………………5 2.2.2 配齒計算…………………………………………………………………………5 2.2.3 初步計算齒輪的主要參數(shù)………………………………………………………6 2.2.4 嚙合參數(shù)的計算…………………………………………………………………7 2.2.5 幾何尺寸計算……………………………………………………………………9 2.2.6 裝配條件的驗算…………………………………………………………………12 2.2.7 傳動效率的計算…………………………………………………………………13 2.2.8 結構設計…………………………………………………………………………14 2.2.9 齒輪強度驗算……………………………………………………………………22 3 總結………………………………………………………………………………… 29 參考文獻………………………………………………………………………………30 致謝………………………………………………………………………………………31 附錄………………………………………………………………………………………32
