Operational maintenance safeguard, bearing and roll shaft are difficult to dismounting, change relatively difficult.
At present, the bearing of the embedded roller of bearing and the dismounting of roll shaft have two kinds of forms, and the first is artificial by external force pair
Bearing and roll shaft are dismantled, and this method is usually to hang oneself one to swing at sky coupler head and hammers into shape and clash into by manpower, passes through
External force is removed roll shaft from roller shell, owing to the shock dynamics of long-drawn-out hammer is bigger, it is easy to the end mushrooming deformation of roll shaft, make roller
Axle and the more difficult dismounting of bearing, the most also can cause the damage of roll shaft and bearing, add the work of maintenance cost and workman
Intensity, brings unnecessary loss to enterprise；Another kind is made by special extracting tool and dismantles, and existing roller is dismantled
Device, is mainly made up of securing plate, bearing plate and three pull bars, and securing plate and bearing plate are fixed together by three pull bars,
Bearing plate has jack, by the pressure of jack, roll shaft and bearing removal is got off, the scope of application of this provision for disengagement
Less, it is impossible to the roller of various length, diameter is carried out dismantlement work, and its structure arranges unreasonable, the fixing comparison of roller is stranded
Difficulty, can only be fixed up roller by the chucking power between two securing plates, even if fixed, the center of roll shaft is the most very
Difficulty is alignd with jack, and top rod coordinates with roll shaft, it is difficult to ensure that it is on the same center of circle, makes the discontinuity of roll shaft, leads
Cause roll shaft and bearing is difficult to dismounting.
Utility model content
