旋转餐桌机构设计 ［摘要］根据现有资料,最早的旋转餐桌出现在18世纪的英国,至今有200年的历史,而旋转餐桌被国人普遍接受,则是在20世纪晚期,短短的数年时间,餐桌可以旋转已经被人们认为是饭店餐桌必备的功能。聚餐时,围绕的客人比较多,这就使得方向的不同可能很难夹取自己喜欢的菜,为此旋转餐桌就很好的满足了大众这一方面的需求 本文设计的旋转餐桌由电动机控制转盘正转、反转及停止的旋转餐桌。1400rpm的电机通过减速装置减速及改变传动方向，从而实现转盘低速匀速转动的功能。减速装置主要包括减速器和锥形齿轮的设计。减速器包括轴、箱体和齿轮的设计，轴承、联轴器的选择。 ［关键词］旋转餐桌；机构设计；减速箱 Desig
