Description
Technical field
The utility model relates to a kind of reducing mechanism, in particular a kind of Raymond mill grinding roller.
Background technology
Raymond mill host work process is to drive central shaft through transmission device to rotate, and the upper end of axle is connecting the plum blossom frame, Burnisher apparatus is housed on the frame and forms the swing fulcrum; Grinding roller is in the bull ring revolution; Grinding roller itself is because of the rubbing action rotation, and the material that gets into main frame obtains along with the frictional impact of grinding roller and bull ring pulverizing, and fine grained is crossed analytical engine with the air communication that blower fan produces; Collect with bag hose, coarse granule continues to reach pulverizing.Grinding roller does not receive axial force, and load is more single, use limitation should be only in the wearability of surfacing; But the rotational load of grinding roller mainly relies on lower bearing to support at present, and contact-making surface is little, and bearing wear is very fast; Lithium saponify is added in the lubricated dependence of bearing, but the sealing system leakage of oil easy to wear that axle sleeve and reinforced seal are formed, the positive and negative tooth of spindle nose part and cap portion wearing and tearing are very fast in addition; Can cause grinding roller integral body down to come off; And be difficult in the running finding that when treating shutdown inspection, main shaft is often scrapped.In view of above deficiency, one is safeguarding preferably under the situation, and the duration of runs of grinding roller, at most also only about 500 hours, frequency of maintenance was high, and cost is expensive, and is prone to cause grinding machine that other faults take place.
The utility model content
The purpose of the utility model is to overcome the deficiency of prior art, and a kind of Raymond mill grinding roller is provided, and through transforming the internal structure of grinding roller, the stability when strengthening running significantly improves the life cycle of grinding roller.
Technical scheme: the utility model comprises cover, top cover labyrinth plate, lower seal cover plate, copper sheathing and grinding roller in main shaft, through hole, spindle nose, back shaft, grinding roller cover, the grinding roller; Wherein: through hole runs through and is arranged in the main shaft, and spindle nose is arranged at the top of main shaft, and the grinding roller cover is socketed on the main shaft; The top of grinding roller cover links to each other with spindle nose, and the bottom is socketed in that grinding roller is interior to be overlapped, and back shaft is near the top of main shaft and be fixed on grinding roller and put; Copper sheathing is socketed in the bottom of main shaft; Cover is positioned on the copper sheathing in the grinding roller, and the two ends of cover are sealed on the main shaft through top cover labyrinth plate and lower seal cover plate respectively in copper sheathing and the grinding roller, and grinding roller is fixed in the grinding roller and puts.
Said spindle nose is provided with the spindle nose gland, and the spindle nose gland links to each other with the grinding roller cover.
The bottom of said main shaft is provided with support ring, following support ring, locked spacer and adjustment nut; Wherein, Last support ring, following support ring, locked spacer and adjustment nut are positioned at the lower seal cover plate; Last support ring is connected to the end of interior cover of grinding roller and copper sheathing, and following support ring links to each other with the adjustment nut, and the adjustment nut links to each other with locked spacer; The bottom spiral of adjustment nut and main shaft links to each other, and last support ring links to each other with following support ring.
Beneficial effect: the utility model is compared prior art and is had the following advantages; The utility model is at the centre drill through hole of main shaft, and the top changes positive and negative tooth and cap into the gland form, and through hole is used for refueling; Logical through scurrying of internal oil passages, make all actuated elements all steep in oil; Cancellation metal (upper, load change by the copper sheathing supporting, and the form that terminal location adopts steel, copper sheathing to combine has increased contact area, has solved original bearing wear problem faster; In the terminal form that adopts oil sealing, wool felt and gland to combine of grinding roller cover, well seal up the inner lubricating oil of grinding roller; Because the improvement of internal lubrication and main axle structure, a few element running effect that bears rotational load is guaranteed, and can reach the duration of runs more than 1 year, has greatly reduced maintenance cost, has improved the service efficiency of machine.
