JZM750锥形反转出料砼搅拌机，其托轮总成减速器与托轮轴原结构联接方式如图1所示。由于内花键套和托轮轴是一个整体，不仅给加工制作带来了困难，更主要的是装配时同轴度难以保证，拌筒在搅拌工作中径向跳动较大，四只托轮时有个别悬空不接触拌筒轨道，导致噪声大、工作平稳性 JZM750 cone reversal discharge rake mixer, the supporting wheel assembly reducer and the original structure of the wheel shaft connection shown in Figure 1. Since the inner splined sleeve and the supporting shaft are a whole, it not only brings difficulties to the processing, but more importantly, it is difficult to guarantee the coaxiality during assembly, and the radial runout of the mixing tube in the mixing work is relatively large. When four supporting wheels are used, Some individuals do not touch the mixing drum track, resulting in large noise and smooth operation
