2K-H行星減速箱設計
摘要：在給定傳動比、扭矩、模數及行星輪個數的條件下進行了行星減速器的總體方案設計、常規設計計算、輸出軸的工藝流程設計及繪制總裝圖和部分零件圖。
 行星減速器的總體方案設計選用太陽輪浮動的均載機構，太陽輪通過單齒聯軸器與高速軸聯接實現浮動，這種浮動方法浮動靈敏，結構簡單，易于制造，便于安裝。太陽輪與齒輪聯軸器的外齒半聯軸套做成一體，內齒輪設計成內齒圈的結構，行星架選用剛性較好的雙側板整體式結構，與輸出軸法蘭式聯接，行星架與輸出軸通過兩個對稱布置得定位銷保證同軸度。齒輪聯軸器選用鼓形齒齒輪聯軸器，鼓形齒齒輪聯軸器允許兩軸線有較大角位移，相對承載能力較強，并且易于安裝調整。減速器齒輪采用油池潤滑，軸承采用飛濺潤滑。
 根據總體設計方案和常規設計計算繪制總裝配圖以及太陽輪、行星架、輸入軸、輸出軸的零件圖。
 輸入軸的工藝流程設計對輸入軸進行工藝分析，繪制零件圖；確定毛坯的制造形式；制定零件的機械加工工藝路線并填寫工藝過程卡和工序卡。

2K-H planetary gear box design
Abstract：In a given gear ratio, torque, modulus, and the number of planets round under the conditions of the planetary reducer for the overall program design, conventional design, the output shaft of the process design and draw parts assembly diagram and Fig.
 Planetary reducer selection of the overall design of the sun round the floating bodies are set, the sun wheel gear coupling with a single high-speed shaft connected to the realization of floating, the floating floating method is sensitive, simple structure, easy to manufacture, easy to install. Round the sun gear coupling with the second half of the outer sleeve teeth into one, with gear designed with the structure of ring gear, planetary rigid frame a better selection of both the overall board structure, with the output shaft flange-type connection, planetary output shaft through the frame with two pins in a symmetrical arrangement to ensure coaxiality. Selection of drum gear coupling tooth gear coupling, gear coupling crown gear axis to allow the two larger angular displacement, load-bearing capacity is relatively strong, and easy to install and adjust. Used oil tank gear reducer lubrication, bearing lubrication using splash.
 According to the overall design of conventional design and calculation programs and the general assembly drawing, as well as round the sun, planetary plane, input shaft, output shaft of the parts diagram.
 Input shaft of the process design of the input shaft to process analysis, mapping parts diagram; to determine the manufacture of blank forms; the development of parts of the machining process and complete the process route and process Card card.
