摘要气动绞车广泛应用于矿山、水利、码头、建筑等行业,在对提升,牵引等工作上发挥极其重要的作用。气动绞车较之其他类型绞车更加环保,因其动力来源为空气,正因如此,其更能适应一些特殊场合。本次设计充分利用了气动马达的优势,初步对气动绞车的应用进行了研究并设计了一套气动绞车的方案。针对过去气动绞车牵引速度慢、绞车实际运行质量较差,效率偏低、以及适应工作环境等要求。本课题为解决以上问题,采取了使用大功率马达,二级齿轮—行星轮减速器,卧式结构及手动外抱式刹车装置来对绞车进行设计,以期达到所需要求,寻求所期望的最佳方案,并初步探求其在真正生产实践中所能发挥的效果。52527

Abstract The air winch widely used in mining, water conservancy, port, construction and other industries, play an extremely important role to enhance traction work. Pneumatic winch is more environmentally friendly than other types of winches, because of its power source to the air, which is why it can adapt some special occasions. The design takes advantage of the advantages of pneumatic motor, the initial application of pneumatic winch research and design of a pneumatic winch program. Requirements for pneumatic traction winch speed is slow, poor quality of the actual operation of the winch, low efficiency, and to adapt to the work environment. The subject to solve the above problem, the use of high-power motor, two gears - planetary gear, horizontal structure and manual taken hold brakes winch design to meet the required specifications, to seek the desired good program, and initially to explore the effect that can be played in real production practice.
