摘要

我国煤炭资源比较丰富，煤矿开采存在着许多技术问题，跟国外发达国家比仍然存在很大的差距，特别是一些传统煤矿开采技术上仍然驻足不前，特别是提升机的安全保障很难达到要求。本次设计主要是大型矿用提升机动力部分及传动装置的设计计算及其强度校核，该提升机是多绳摩擦式，适用于大中型煤矿的提升运输。
本论文针对矿山机械的特殊要求，重点设计动力部分及传动部分，两个部分是提升机的关键部分，动力部分如果不选择合适的电机，将会造成动力不足或者浪费能量；提升机的传动部分为减速器，在设计时需要考虑轴承受的弯扭力矩，齿轮是否满足强度要求，轴的工艺要求等.多绳摩擦式矿用提升机，各零件均按标准设计，安全可靠性高，适用于大中型矿井的提升运输。

ABSTRACT
China's rich coal resources, coal mining, there are many technical issues, with developed countries than there are still big gaps, especially some of the traditional small and medium-sized coal mining technology still does not stop the former, in particular to enhance the safety and security of a machine Difficult to meet the requirement of this design is mine hoist drum and a fixed spindle device design and strength check calculation, the hoist is a two-reel structure, applicable to the large and medium-sized coal mines Upgrading transportation.
    This paper for the special requirements of mining machinery, spare parts and focus on design reel main components, the two parts is a key part of hoist, roll strength enough lead to a direct consequence of the cartridge case is the collapse pressure, weld cracks, and so is the spindle Transfer power plant, to be considered in the design of its affordable bending and torsion torque, the key strength of the spindle assembly and the weakening of the problem, the axis of requirements . according to various parts of standard design, Security high reliability, application and upgrade the transport of large and medium-sized mines.
