文档介绍：摘要
JDM-30型无极绳绞车是一种新型的矿山辅助运输设备。其主要适用于煤矿井下长运距,多起伏的运输巷道,特别适用于大型综采设备的运输牵引和长运距矿车及材料的运输。能大大提高运输效率和运输安全可靠性,防止放打滑现象。该绞车的设计对于完善无极绳绞车起着重要的基础作用。
JDM—30型无极绳绞车主要由电动机、联轴器、减速器、卷筒和制动闸等组成。本毕业设计的重点是减速器的设计,该传动系统采用了五级传动,第一级为直齿圆锥齿轮传动,其余为圆柱直齿轮传动,采用了两个双联齿轮,最后一级的小齿轮和大齿轮靠过桥齿轮连接,形成封闭的传动路线。传动原理简单、可靠、高效。
JDM—30型无极绳绞车具有良好的防爆性能和制动性能,容绳量大、适用条件强、使用寿命长、传动效率高等特点。该绞车结构紧凑,外形尺寸小,能够整机下井;结构为近似对称布置,外形美观,成长条形,底座呈雪橇状;绞车重心低,底座刚性好,可安装地锚,运转平稳,安全可靠,维护方便。

ABSTRACT
JDM-30-Promise rope winch is a new type of mine-assisted transport equipment. The main application is long distance in the coal mine, more ups and downs of the roadway, especially for large transport fully mechanized coal mining equipment traction and long distance transport cars and materials. It can greatly improve transport efficiency and transport safety and reliability and prevent-skid phenomenon. The winch design plays an important basic role in improving the Promise of the rope winch.
JDM-30-Promise rope winch is posed of the motor, coupling, reducer, brake drum gates, and ponents. The graduation project focused on the design of the reducer, the drive system uses five transmission, the first class uses straight bevel gear, the rest is straight cylindrical gear transmission, it uses two pairs of gears, and the small gear and the big gear of the last one are c onnected by the bridge formed a closed transmission line. Transmission principle is simple, reliable and efficient.
JDM-30-Promise rope winch has a good explosion-proof performance and braking performance, large capacity to justice, conditions of application strong, long-life, high efficiency drive. The winch pact structure, small shape size, can go down with overall unit; structure is similar to symmetrical layout, aesthetic appearance, growth strip, a sled-shaped base; the gravity centerof the winch is low, rigid base, and can be installed to anchor, a smooth operation, safe and reliable , easy maintenance.
