多功能跑步机设计(含CAD零件图装配图)(外文翻译,论文说明书13000字,CAD图8张)
摘要
近年，经济发展迅速，科技水平也在不断的提高，人们的生活重心也由吃饱穿暖转变为如何高质量、健康的生活。现在人们的伙食都很好，但是因为日常工作或生活中，活动量不够，绝大多数人们的身体都处于亚健康的状态。所以，越来越多的人们开始追求健康生活，健康生活就要从动起来开始。对于运动，居家运动的最好方式就是跑步机。
跑步机作为当今家庭健身器材中最为常见的一种，已经进入到大多数人们的生活中。且市场上的跑步机现在技术成熟，功能多样化。由于大规模的工业效应，跑步机的价格也在不断的降低。随着国内生活水平的不断提高，跑步机也会进入到越来越多的家庭中。
跑步机主要由机架、滚筒、带传动、轴、电机等主要零部件组成。本文主要对关键零部件进行计算。同时，根据重点零部件的设计情况，出具相对应的CAD图纸。
关键词：跑步机；多功能；设计
Abstract
In recent years, the economy has developed rapidly, and the level of technology has also been continuously improving. The focus of people's lives has shifted from being full and warm to living a high-quality and healthy life. Now people's food is very good, but because of the lack of activities in daily work or life, most people's bodies are in a state of Suboptimal health. So, more and more people are pursuing a healthy life, and a healthy life needs to be driven to start. For sports, the best way to exercise at home is the Treadmill. [版权所有：http://DOC163.com]
As the most common type of home fitness equipment nowadays, the treadmill has entered the lives of most people. And the treadmills on the market are now technologically mature and have diverse functions. Due to the large-scale industrial effect, the price of Treadmill is also decreasing. With the continuous improvement of domestic living standards, treadmills will also enter more and more households.
The treadmill is mainly composed of main components such as frame, drum, belt drive, shaft, motor, etc. This article mainly calculates key components. At the same time, corresponding CAD drawings will be issued based on the design of key components.
Key words: Treadmill; Multi functional; design
