文档介绍：车载打桩起重机减速器及卷筒设计
摘要
这篇论文设计的是打桩机起重装置。它集机械设计最新理念、铸造工艺最新技术及CAD、CAM于一身,是将最新设计技术、CAD、CAM应用于实际的一个实例。文中涉及了蜗杆减速器和卷筒装置的设计、计算和校核,以及后期三维建模的相关内容。
将蜗杆减速器应用于起重装置不仅提高了工作的可靠性,也大大提高了工作效率和经济效益。蜗杆减速器以其传动平稳,无噪声,结构紧凑,可以自锁等优点在起重装置及传动装置中得到了广泛的应用。在该系统中,选用的是单级蜗杆减速器。单级蜗杆减速器机构简单,易于设计,设计基础和经验丰富,且可以自锁,与其配套的附件容易买到。
卷筒结构设计的好坏决定着整个系统性能的优劣。该起重装置采用了最新的结构,并在铸造上采用了最新的工艺来提高卷筒的强度、硬度和耐磨性。
该系统能安全可靠地控制钢丝绳的牵引长度、速度,并能够实现作业中的自锁。论文中主要包括了减速器设计及计算和卷筒设计部分,并结合图表作了充分的讲解。

Design of car reducer and drum crane piling
Abstract
It is about the draw equipment of drill-machine in this paper. It concentrates the latest mechanical design concepts, casting techniques and the latest technology of CAD/CAM. The thesis is an example of the application of theory. It concludes the design,calculation and checking out of the worm gears speed reducer and the reel system, as well as the next three-dimensional simulation.
Worm gears speed reducer will not only enhance the work for the reliability, but also greatly enhance the efficiency and cost-effectiveness. The worm gears speed reducer is widely application in drive system and transmission system because of its smoothness, the non-noise, the structure tightly packed and the ability of auto-lock. In addition, the reel system is very important in the draw system, so goodness or badness of the design of it directly have impact on the performance of the whole system. This draw equipment applies the latest structure, and the latest advances in technology to improve reel’s intensity, hardness and abrasion resistance.
In this system, the choice is the single-grade worm gears speed reducer. Single-grade worm gears speed reducer has a simple structure, easy to design, foundation design and experience, and has the ability of auto-lock, and it’s supporting accessories are easy to buy. The system can safely and stably control the length, speed, and to achieve operational auto-locks. The whole paper concludes the design and calculation of the speed
