2、求调速性能好,特别要空钩能快速下降。对安装就位或敏感的物料,要能 以微动速度下降卷扬机包括快速卷扬机和慢速卷扬机,仅能在地上使用,它以电动 机为动力,经弹性联轴节,三级封闭式齿轮减速器,牙嵌式联轴节驱动卷筒,采用 电磁制动。该产品通用性高、结构紧凑、体积小、重量轻、起重大、使用转移方便, 被广泛应用于建筑、水利工程、林业、矿山、码头等的物料升降或平拖,还可作现 代化电控自动作业线的配套设备。尽管其应用非常广泛,但在实际应用过程中目前仍 存在着许多急待解决的问题,普遍存在的不足是:体积大、过载能力差、噪音大、 效率低、使用寿命短、工作不够安全可靠等,有些产品还已列入国家淘汰产品,开 展卷扬机机设
3、计、性能分析及应用研究, 具有较大的实用价值和重要的现实意义, 本次通过对漫步卷扬机传动系统的设计,希望能找出现阶段所存在的问题,并提出 解决方案,以此试图对我国卷扬机的开发和改进祈祷借鉴作用。 关键词关键词:卷扬机 ; 设计; 性能分析; 通用性 II Abstract The widely applied in construction, water conservancy, metallurgy, lifting operation. Hoist and winch, is an important part of lifting, vertical transport machiner
4、y, with the derrick, maist is composed of motor, coupling, brake, gear box and reels, mounted on the frame. Electric hoist is also known as electric hoist. For lifting height and loading amount is large, busy with work, request good speed performance, especially to the empty hook to the rapid declin
5、e in. The installation or sensitive material, to be able to decrease the speed of fast hoist winch fretting and slow winch, can only be used on the ground, it takes the motor as power, through an elastic coupling, three closed type gear reducer, tooth type coupling drive drum, using electromagnetic
6、brake. This product is high universality, compact structure, small volume, light weight, big, use convenient, it is widely used in construction, water conservancy, forestry, mining, port materials such as lifting or flat mop, ancillary equipment can be automatic line for modern electronic. Despite its very wide application, but in the actual application process still exist many urgent problem
