重型车床主传动系统的性能,直接关系到机床的刚度和精度以及机床的使用性能和效率。为了缩短传动链,简化机械结构,提高主传动的刚度和精度,合理安排主传动系统的结构是很重要的。卧式车床主传动有交流传动和直流传动两种形式,重型车床的调速范围,一般要求在100~250。采用交流拖动时,为了达到要求的调速范围,就要配一个16~24级的多级机械变速箱。这样就会使变速机构复杂变速箱的外廓尺寸就会庞大,而且
Heavy-duty lathe main drive system performance, is directly related to the rigidity and accuracy of machine tools and machine tool performance and efficiency. In order to shorten the transmission chain, simplify the mechanical structure and improve the rigidity and accuracy of the main drive, it is very important to arrange the structure of the main drive system reasonably. The main drive horizontal lathe AC drive and DC drive in two forms, heavy duty lathe speed range, the general requirements of 100 ~ 250. Using AC drag, in order to achieve the required speed range, it is necessary with a 16 to 24 multi-stage mechanical transmission. This will make the gearbox complex gearbox outline size will be huge, but also
