摘     要

        JDM-30型無極繩絞車是一種新型的礦山輔助運輸設(shè)備。其主要適用于煤礦井下長運距，多起伏的運輸巷道，特別適用于大型綜采設(shè)備的運輸牽引和長運距礦車及材料的運輸。能大大提高運輸效率和運輸安全可靠性，防止放打滑現(xiàn)象。該絞車的設(shè)計對于完善無極繩絞車起著重要的基礎(chǔ)作用。
JDM—30型無極繩絞車主要由電動機、聯(lián)軸器、減速器、卷筒和制動閘等組成。本畢業(yè)設(shè)計的重點是減速器的設(shè)計，該傳動系統(tǒng)采用了五級傳動，第一級為直齒圓錐齒輪傳動，其余為圓柱直齒輪傳動，采用了兩個雙聯(lián)齒輪，最后一級的小齒輪和大齒輪靠過橋齒輪連接，形成封閉的傳動路線。傳動原理簡單、可靠、高效。
JDM—30型無極繩絞車具有良好的防爆性能和制動性能，容繩量大、適用條件強、使用壽命長、傳動效率高等特點。該絞車結(jié)構(gòu)緊湊，外形尺寸小，能夠整機下井；結(jié)構(gòu)為近似對稱布置，外形美觀，成長條形，底座呈雪橇狀；絞車重心低，底座剛性好，可安裝地錨，運轉(zhuǎn)平穩(wěn)，安全可靠，維護方便。

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 mainly composed of the motor, coupling, reducer, brake drum gates, and other components. 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 gear.It 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 has compact 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.
