摘   要

     本次設計的題目是3噸調度絞車的設計。調度絞車由于結構簡單、重量不大、移動方便，而被廣泛應用于礦山地面、冶金礦場或建筑工地等進行調度和其它運輸工作。
絞車的主要特點為：結構尺寸和重量較小、鋼絲繩速度不高，安裝及撤除操作方便、啟動平衡（穩）、故障率低、常見故障易處理、維護方便。
我國許多調度絞車的設計是引進前蘇聯的技術，并在其基礎上作了一些改進，本設計方案的主要特點：該型絞車采用兩級內嚙合傳動和一級行星輪傳動。Z1/Z2和Z3/Z4為兩級內嚙合傳動，Z5、Z6、Z7組成行星傳動機構。在電動機軸頭上安裝著加長套的齒輪Z1，通過內齒輪Z2、齒輪Z3和內齒輪Z4，把運動傳到齒輪Z5上，齒輪Z5是行星輪系的中央輪（或稱太陽輪），再帶動兩個行星齒輪Z6和大內齒輪Z7。行星齒輪自由地裝在2根與帶動固定連接的軸上，大內齒輪Z7齒圈外部裝有工作閘，用于控制絞車滾筒運轉。
為了達到良好的均載效果，在設計的均載機構中采取無多余約束的浮動方式。另外，變位齒輪的使用也可以獲得準確的傳動比，提高嚙合傳動質量和承載能力。
本次設計主要對兩級內嚙合傳動和一級行星輪傳動、滾筒結構、制動器等進行了詳細的設計。

關鍵詞： 調度絞車；行星齒輪；行星傳動；內嚙合傳動

Abstract

       The design is the subject of three tons scheduling winch design. Scheduling winch as simple structure, less weight, mobile convenience, and the ground was widely used in mining, metallurgical mines or construction sites, such as dispatching and other transportation work.
  Winch the main features are: small size and weight of the structure, the rope speed is not high, installation and removal easy to operate, start balance (stability), the failure rate is low and easy to deal with common fault, and easy maintenance. Many of our scheduling winches are designed to introduce the former Soviet Union, and on the basis of their made some improvements, the design of the main features: the use of two-winch internal drive and a planetary gear transmission. Z1/Z2 and Z3/Z4 for two Internal Drive, Z5, Z6, Z7 composition of planetary transmission mechanism. Installation of the motor shaft head of the extended sets of gear Z1, through the gears Z2, with gear Z3 and Z4, the movement spread to gear Z5, the Z5 is the planetary gear wheel of a central round (or round the sun), Further promote the two planetary gear Z6, and the gear Z7. Planetary gear freely installed in the two driven and connected to a fixed axis, the largest in the gear Z7 Gear work with the external gateway, used to control winch drum operation.
  In order to achieve good results, are contained in the design of the bodies contained no extra bound to take the floating manner. In addition, the use of variable gear can also get accurate than the drive to improve the quality and meshing transmission capacity.
 The design of the two main transmissions and meshing with a planetary gear transmission, the drum structure, such as brake carried out a detailed design.

Key words: scheduling winch; planetary gear; planetary transmission; Internal Drive
