摘 要
本次设计的题目是3吨调度绞车的设计。调度绞车由于结构简单、重量不大、移动方便,而被广泛应用于矿山地面、冶金矿场或建筑工地等进行调度和其它运输工作。
绞车的主要特点为:结构尺寸和重量较小、钢丝绳速度不高,安装及撤除操作方便、启动平衡(稳)、故障率低、常见故障易处理、维护方便。
我国许多调度绞车的设计是引进前苏联的技术,并在其基础上作了一些改进,本设计方案的主要特点: 该型绞车采用两级内啮合传动和一级行星轮传动。Z1/Z2和Z3/Z4为两级内啮合传动,Z5、Z6、Z7组成行星传动机构。在电动机轴头上安装着加长套的齿轮Z1,通过内齿轮Z2、齿轮Z3和内齿轮Z4,把运动传到齿轮Z5上,齿轮Z5是行星轮系的中央轮(或称太阳轮),再带动两个行星齿轮Z6和大内齿轮Z7。行星齿轮自由地装在2根与带动固定连接的轴上,大内齿轮Z7齿圈外部装有工作闸,用于控制绞车滚筒运转。
为了达到良好的均载效果,在设计的均载机构中采取无多余约束的浮动方式。另外,变位齿轮的使用也可以获得准确的传动比,提高啮合传动质量和承载能力。
本次设计主要对两级内啮合传动和一级行星轮传动、滚筒结构、制动器等进行了详细的设计。

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.
