【技术实现步骤摘要】
本技术涉及一种车床高速主轴,尤其是设计一种通过电磁绕组传动主轴,达到高速稳定切屑的目的的电主轴。
技术介绍
现有机床一般都通过系统操作,由主电机通过皮带与主轴传递,达到驱动效果。该技术方案受到结构限制,仅适用与小规格的稀有金属加工,如果遇到大规格的稀有金属,主轴的转速及驱动力远远大不到切屑要求,无法实现大规格稀有金属的切屑目的。
技术实现思路
为解决现有技术存在的不足,本技术的目的是提出一种电主轴,其在其它部件不变的情况下,通过改变主轴箱体结构,实现最大回转直径在400mm以内稀有金属高速切削的目的。本技术的技术方案是:一种电主轴,包括主轴箱,其特征在于:所述主轴箱上设有供冷却水进入的冷却水进孔以及供冷却水流出的冷却水出孔,所述主轴箱内设置有与冷却水进孔以及冷却水出孔联通的冷却水循环通道,所述主轴箱内安装有定子和转子,一根主轴从主轴箱中间穿过,所述转子安装在定子内侧,转子与主轴之间设有衬套,所述主轴箱的前、后端分别由前、后轴承座密封,所述前轴承座和后轴承座采用螺栓紧固安装在主轴箱的前、后端,所述主轴的前端设有前轴承 ...
