At present, most small ball mills appear in market are equipped with medium diameter roller bearing. These kind bearing bases mostly adopt dry oil lubrication. But in recent years, because the operator and oilman cannot observe the oil level and complement oil in a timely manner, resulting in lubricating greases in bearings mounted in the box cannot be clearly reflected and leads a shortage of oil. This will not only cause a shortened service life of bearings, but also can cause damage to bearing. It will bring bearing manufacturers a lot of inconvenience and economic loss. In order to solve this problem, Hongxing Mining machinery has recently developed thin oil rolling bearings lubrication. This new form of hollow shaft with rolling bearing installation method is a progress and improvement on the basis of the original installation method. This new thin oil lubrication bearing seat is essential to ensure good lubrication of the bearing.
1. Feeding part: This part consists of end cap with hollow shaft neck, united feeder, sector lining plate and axis neck inner housing. The hollow shaft neck can protect the axis neck inner surface from wearing by feeding. The inner surface of the inner housing is equipped with screw which contributes to feeding. The feeder is fixed at the end of the inner housing by bolt. Generally, the united feeder is the first choice, followed by the drum feeder and the snail feeder.
2. Discharge part: This part consists of end cap of hollow shaft, grid lining plate, wedge, centre lining plate, and axis neck inner housing. There are eight actinoid fillets, acting as the isolation board. There is grid lining plate between the fillets which is fixed by wedge. The wedge is fixed onto the end cap by screw passing through the fillet on the wall. The front edge of the lining plate holds up all grid lining plates in the central part. The inner housing of the hollow shaft neck is made into the broadening formation blade on one end of the discharge grid to lead the pulp washed by isolation board to flow out with the blades. All the discharge part and the feed part are fastened on the cylinder flange.
3. Transmission part: This part consists of gearwheel, pinion, drive shaft, and elastic coupling. The grinding mill cylinder is driven by gear assembly, electric motor and coupling. The gear assembly consists of gear ring on the discharge end of the cylinder and drive gear. The drive gear is equipped on the drive shaft which rest on the two double-row ball self-aligning bearing in the bearing block. The gears are covered by the dust cap totally.
