Due to the heavy-duty, high-speed, periodic impact and strong vibration characteristics of the ultrafine mill gear, the gear wear phenomenon often appears in the work. When the wear is serious, the damage of the parts will be caused, and the life of the gear will be expected by the manufacturer. The service life is very large, so this article mainly describes how to prevent the wear of the
ultrafine mill gear to reduce gear wear.
Prevent hollow shaft from leaking
It is well known that the grinding side of the empty shaft of the mill will aggravate the gear wear of the ultra-fine mill. Therefore, for the case of hollow shaft slurry leakage, the direct welding repair method can be adopted. First, the feed bushing is fixed and fixed on the hollow shaft by the connecting bolt, and then 4 points are selected in the matching surface range of the feeding bushing and the other end of the hollow shaft. Fixing and adjusting with inclined iron, so that the feeding bushing is fixed. After fixing, the feeding bushing, the end cover and the inclined iron are welded together. Remember to fill the cavity with filler. Prevent the slurry from wearing the cavity. After welding, it strengthens the firmness, prevents slurry leakage and reduces gear wear.
Improve lubrication
In order to improve the wear phenomenon of the gear and improve the service life of the gear, the technician improves the transmission gear lubrication system of the
T130X Reinforced Ultrafine Mill. With the automatic fuel injection lubrication device, the injection lubrication point is selected at the meshing entry point of the two gears. This improvement only needs to move the automatic nozzle to the point before the gear meshes, fix it on the gear cover, and connect the corresponding oil pipe. The gear lubrication condition is improved, the oil splash is prevented, the gear has good lubrication effect, the gear wear is reduced, the gear running life is effectively extended, and the lubricating oil consumption is saved.
Reinforced sealing element
The semi-open seal type transmitted to the ultra-fine mill gear is changed into a closed type to reduce the amount of dust entering the mating surface of the gear pair, and to reduce the occurrence of worn phenomenon of the surface-grinding surface gear. In addition, the sealing structure of the bolts of the ultra-fine mill liner should be strengthened to prevent dust from entering.
Installation and maintenance should be up to standard
Strictly install and overhaul according to the installation and inspection standards of the superfine mill to ensure the coaxiality between the motor shaft and the pinion axis, the parallelism between the pinion axis and the large gear axis, the side clearance of the meshing gear or The top clearance meets the requirements. At the same time, daily maintenance should be strengthened, especially the parallelism between the pinion axis and the large gear axis. The side clearance or top clearance of the gear should be within the allowable range of the equipment to avoid aggravating the wear of the gear.
