设计简介
摘要
我设计的是一台水果糖糖料拉白机。型号为TMJ200型。该拉白机对熬出的糖料进行拉伸，让糖料成为白色，使其光泽光亮，常用于酥芯糖糖衣的生产。该机的工作效率为25kg/次，次/8~10分钟。该机是一个传动机构，我对其传动机构进行设计。该机的工作状况是，通过电动机传到减速器，再通过减速器的变速运动，经过轴带动两曲柄的运动，两曲柄是进行相向运动，进行糖料的拉伸，达到工作的目的。在这次设计中我主要是对该拉白机的结构进行设计的。其主要步骤是，先选择其电动机的型号，根据其工作效率和要求来选择其型号的。然后再对其传动机构进行设计的，在这一部分我设计
了主轴和齿轮，还计算了其传动比。其机的主要部分就是曲柄和杠杆。
