3Z型行星齒輪減速器設計
摘要：這次畢業設計的內容是根據課題做一個行星齒輪減速器。通過比較，選用3Z(II)型行星齒輪減速器。
 本次設計要完成的主要內容：
確定傳動方案  傳動方案的確定包括傳動比的確定和傳動類型的確定。
設計計算  每級傳動結構的設計計算，大致包括：傳動比的分配、傳動系統運動學和動力學計算、傳動零件的設計、軸的設計計算與校核、軸的選擇與計算、鍵連接的選擇與計算、箱體的設計、潤滑與密封的選擇和傳動裝置的附件說明等。
裝配圖以及各零件圖的設計。
 通過本次設計，可知行星齒輪減速器有著體積小、質量小、結構緊湊和傳動效率高等特點，但由于行星齒輪減速器傳動比大，力矩就比其它減速器結構小，行星齒輪減速器自鎖角大止退性差而不適合啟動用。

 The design of 3Z planetary gear reducer
Abstract: The content is based on graduate design to be a subject of planetary gear reducer. 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.
