The utility model discloses a maintenance free grinding roll assembly device of a pulverizer matched with a pulverizer, which is characterized in that the sealing structure of the roller device is improved to protect the rolling bearing from dust damage. The sealing structure includes between the gland and sleeve skeleton type set from the inside out seals, mechanical seals and self-locking nuts; the mechanical seals respectively and rotating ring and the static ring sleeve is sheathed and friction between the static ring and the circular horn shaped rubber spring is coaxially and fixedly connected with the rotating ring. With the annular rubber pad fixed coaxial connection, mechanical seal is forced self-locking nut, rubber preload spring will always rotating ring and the static ring is pressed, the friction between the rotating ring and the stationary ring of consumption into automatic compensation, effective protection of dust, to maintain the normal working condition of grinding device assembly roller, the utility model has the advantages of low failure rate, maintenance free, service life is at least 5000 hours.

磨粉机免维护磨辊总成装置(一)
本技术涉及磨粉机部件,具体说是磨粉机的一种免维护磨辊总成 装置。(二)
技术介绍
磨粉机是矿粉行业应用最广泛的机器,它是由悬挂的磨辊总成装置在 运行过程中产生的离心力碾压矿物成为所需矿粉,在磨粉机工作过程中, 磨辊总成装置要承受强烈的冲击、震动以及不均匀的压力,这还不是造成 磨辊总成装置出现故障的主要原因,由于磨辊总成装置工作在高浓度、紊 乱动态、微细粉尘的环境中,磨辊总成装置防尘失效才是其主要的故障原 因,因此磨粉机磨辊总成装置防尘密封可靠与否决定了磨粉机故障率的高 低。磨粉机磨辊总成装置的转动方式主要为滚动轴承的结构方式,其结构 大致为磨辊主轴套装在磨辊套内,磨辊套上下轴承位中的轴承与磨辊主 轴的轴颈配合,磨辊主轴向下伸在磨辊套外,磨辊安装在磨辊主轴的下端, 而轴承密封装置则设置在磨辊套下轴承位与磨辊之间。轴承密封装置的常用结构包括压盖、轴套、自锁式紧固螺母和骨架式 密封圈、四氟摩擦片、羊毛毡等;轴套涨紧在轴承内圈与磨辊之间的磨辊 主轴上,压盖套装在轴套外并与磨辊套下轴承位端面固紧安装,压盖的内 凸台阶顶住轴承外圈, ...
【技术保护点】
磨粉机免维护磨辊总成装置,包括对磨辊套(1)下端磨辊主轴(5)上滚动轴承(2)定位的压盖(3)和轴套(4),压盖(3)与磨辊套(1)底部固连,轴套(4)涨紧在磨辊主轴(5)上,压盖(3)和轴套(4)之间设置有对滚动轴承(2)进行保护的密封装置,其特征在于:所述密封装置包括自内而外设置的骨架式密封圈(6)、机械密封件和自锁式逼紧螺母(7)。
