摘要
如今是体育大时代,对一些人来说体育是一种精神,对另外一些人来说,体育是一种信仰,总而言之,体育已经深深地融入而的生活,成为人们不可缺的娱乐追求。随着姚明、李娜、刘翔等人取得的成绩,已经将体育事业推向了高潮,全民掀起了体育热潮。
排球是世界三大球之一,我国女排曾经取得了辉煌的成绩。一种新型排球发球机的成功设计应用一定程度上可以帮助排球运动员训练。根据市场调研,目前市场上暂时没有排球发球机出售,本机器具有非常好的发展趋势。由此参考我明确了本次设计的主要任务。本次设计任务包括比较本机器与同类产品的差别,介绍排球发球机的基本运行原理,各零部件的选材、安装及操作配合,机器效率及其实用效果的初步确定,提出进一步完善本机器的科学构想。
在本次设计过程中,本人参照以往设计的设计经验,基本完成了预期任务,使得该设备的特点鲜明,排球时速在18-30米每秒之内,发射距离约为20米,并具有上下左右调节装置。结构严谨,造价低廉,移动便利,操作简单。

Volleyball serve machine manufacture process
preliminary design
ABSTRACT
Is now the great age of sports, for some sports is a kind of spirit, for some people, sports is a kind of faith, in a nutshell, sports has been deeply integrated into our life, e a indispensable for our entertainment. With yao, li and liu's achievements, has the undertakings of physical culture and sports to the climax, the raised a hot wave of sports. Volleyball is one of the three big ball, Chinese women's volleyball team has made brilliant achievement. I try to design a new type of volleyball serve machine, used to help the volleyball athletes training.
According to market research, temporarily no volleyball serve machine sold on the market at present, this machine has the very good development trend. The reference I made clear the main task of this design. The design tasks pare the difference of the machine and the same products, introduce the basic operation principle of the volleyball serve machine, material selection, installation and operatio
