食品皮带提升机设计 Desig
n of Food Belt hoist 摘要 食品皮带提升机是为了使食品得到更快运输的一种机械。它是非常重要的运输设备之一，它广泛被用于矿山运输，码头装货，化工运输等重要行业，但对与各种不同情况下的机械设备有一样的设计选材和计算要求。 本文设计了食品加工业中必不可少的食品皮带提升机。食品皮带提升机是运用了皮带提升机的原理开发设计的。食品皮带提升机大致与传统皮带提升机相同，他们都是由皮带，钢带，钢纤维带，塑料带，化纤带作为起重材料和拉拔工件的运输机械。其特征在于用于提升材料的提升装置和用于提高动力的牵引构件，这与其他提升机器明显不同。本文设计的食品皮带提升机是一种小型运输机械，需要的要求是承载能力要求低，运输速度可变，与其他皮带提升机相比之下，他成本更低，设计更加紧凑实用。 从整体结构开始，对整个机器装置的驱动部分和驱动部分进行设计和计算。在驱动装置的设计计算中，该设计使用电动机减速装置作为驱动装置;在传动部件的设计中，定时滑轮与传动装置连接以传递动力。另外，选择和设计了装置的换向辊，压力辊和框架部件，并对其他必要的辅助设备计算与选择。 这次主要设计减速器的结构，确定并选择清扫装置和轴的主要参数，改变方向滚筒的设计，还有制动装置的选择，并且详细分析其工作原理。 关键词减速器；换向滚筒；压轮；托辊 Abstract Food belt hoist is a ki
