Description
Technical field
The utility model relates to a kind of mixing roll device that the slag Vertical Mill rolls use that is used for, and belongs to the cement manufacture plant technical field.
Background technology
The slag Vertical Mill is a widely used equipment in the manufacture of cement; Present most slag Vertical Mill adopts four mixing roll devices; Be that grind grinding roller front end stone rear end, the mixing roll device quantity of this structure is more, has not only improved the purchase cost of equipment; Also time-consuming when changing simultaneously and keeping in repair, effort have increased maintenance cost.In view of this, it is very necessary designing and develop the new mixing roll that uses on the slag Vertical Mill that is applicable to.
The utility model content
The utility model technical problem to be solved provide a kind of simple in structure, durable, compact conformation, running stable, make and install and the special-purpose mixing roll device of slag Vertical Mill easy to maintenance, that cost performance is high and efficient is high.
The technical scheme that solves the problems of the technologies described above is:
A kind of mixing roll device that is used for the slag Vertical Mill; It is made up of roll shaft, wheel hub, roller shell, rolling bearing; Wheel hub is sleeved on the roll shaft through rolling bearing, and the periphery rear end of wheel hub is the protruding conical surface, and the roller shell rear inner wall has the male cone (strobilus masculinus) of the conical surface and wheel hub to be complementary; The inner conical surface of roller shell is pressed on the wheel hub male cone (strobilus masculinus) through bolt, nut, hold-down ring, and a tightening lid is arranged at the two ends of roll shaft.
The above-mentioned mixing roll device that is used for the slag Vertical Mill; Said rolling bearing is double-row conical bearing and cylinder roller bearing; They lay respectively at the front-end and back-end of wheel hub, and by bearing outer ring spacer sleeve and inner ring spacer sleeve location, wheel hub end housing and sealing shroud are with bearing fixing between two bearings.
The above-mentioned mixing roll device that is used for the slag Vertical Mill, the outside end face of said wheel hub has removable wheel hub protective sleeve.
The above-mentioned mixing roll device that is used for the slag Vertical Mill, said roll shaft has a centre bore and grinding machine exterior, and centre bore is equipped with the oil immersion air filter.
The above-mentioned mixing roll device that is used for the slag Vertical Mill, said hub end is stamped seal with O ring, is sealed into 3 road lip-type seals on the grinding roller between the sound part, is dust seal together, and twice are anti-oil seals.
The utility model is applicable to floating roller stone; Slag Vertical Mill with the mixing roll grinding; Have that rolling effect is good, durable, simple in structure, running is stable, make install and easy to maintenance, cost performance is high and characteristics such as efficient height, is the ideal equipment that the slag Vertical Mill rolls.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Mark is following among the figure: axle tightening lid 1, roll shaft 2, main grinding roller rotation monitoring 3, wheel hub protective sleeve 4, wheel hub 5, roller shell 6, hold-down ring 7, end cap 8, axle tightening lid 9, double-row conical bearing 10, outer ring spacer sleeve 11, inner ring spacer sleeve 12, cylinder roller bearing 13, bearing seal 14, wear ring 15.
The specific embodiment
The utility model partly is made up of roll shaft 2, wheel hub 5, roller shell 6, double-row conical bearing 10, cylinder roller bearing 13 etc.
Show among the figure; Wheel hub 5 is sleeved on the roll shaft 2 through double-row conical bearing 10, cylinder roller bearing 13; The periphery rear end of wheel hub 5 is the protruding conical surface; Roller shell 6 rear inner wall have the male cone (strobilus masculinus) of the conical surface and wheel hub 5 to be complementary, and the inner conical surface of roller shell 6 is pressed on wheel hub 5 male cone (strobilus masculinus)s through bolt, nut, hold-down ring 7.End face is provided with removable wheel hub protective sleeve 4 in the outside of wheel hub 5, is not worn with protection wheel hub 5.The roll shaft periphery has also been installed main grinding roller rotation monitoring 3.
Show among the figure; Double-row conical bearing 10 is located roll shaft 2 with cylinder roller bearing 13; Double-row conical bearing 10 not only receives radial load but also bear axial force, and cylinder roller bearing 13 bearing radial force only, the generation of axial force is because roll shaft 2 is in tilted layout with mill.Lean on bearing outer ring spacer sleeve 11 and inner ring spacer sleeve 12 location between two bearings, fix by wheel hub end housing 8 and sealing shroud.
The double-row conical bearing 10 of the utility model does not design the preceding play of dress, guarantees assembling back play by packaging technology, has eliminated the influence of accumulated error to bearing clearance, has improved bearing life greatly.
Roll shaft 2 has a centre bore and grinding machine exterior, so identical with atmospheric pressure with pressure in the bearing chamber, this centre bore is equipped with the oil immersion air filter.Because the mixing roll internal gas pressure is greater than the Vertical Mill internal pressure; So dust can not get into bearing; For preventing that gas with dust from getting into, mixing roll has been taked a seal with O ring wheel hub end housing 8, and 3 road lip-type seals are adopted in the sealing on the grinding roller between the sound part; Be dust seal together, twice are anti-oil seals.
Roller shell 6 has a convexity in the big end of mixing roll, and this convexity can play the intensity that improves the roller shell body, and makes things convenient for the build-up wear-resistant alloy-layer, under the situation that does not influence result of use, has reduced the thickness of wear-resistant alloy layer, has reduced cost.
