堆焊机减速器设计

摘要

机车轮心，即车轮与车轴的接合部分。车轮中心的内孔通过过盈配合牢固地安装在车轴上，这一过程是通过热膨胀法来实现的。为了满足轮轴的工作要求，必须对车轮中心的内孔表面进行焊接和再加工，以恢复其原有的形状和表面光洁度。为此，本文设计了一款三级圆柱齿轮和一级蜗轮蜗杆减速的堆焊机减速器。本文设计的这款减速器，就是为焊机的动力头部分所定制的。

本文主要聚焦于减速器的传动机构和传动轴来设计。这项设计的首要目标是减速器能满足基础性能标准，其次是在此基础上尽量减少减速器的体积和重量使其结构紧凑、加工制造方便。本文的设计重点着眼于达到特定的速比和强度指标。此外，设计时还充分考虑了装配的便利性、体积的优化以及生产成本的降低。因此，所设计的减速器以生产简单、结构紧凑、高可靠性、强实用性、装拆方便以及低成本为特点。
