Abstract
Guide roller supporting bearing block.Relate to the supporting shaft holder being applied in and supporting deflector roll in weaving, dyeing.Be arranged on deflector roll two ends, at least the bearing support of one end is slip shaft bearing.The present invention adopts interference fit to locate due to deflector roll spindle nose and bearing inner race, and slippage is just carried out between bearing support outer ring and slippage slot, so can not there is the wear phenomenon of spindle nose and bearing inner race in deflector roll work operation process.And further, the bearing block of Zhong You one end, deflector roll two ends is completely fixed, heat stretch slippage only bearing support at one end carry out; And the outer ring of slip shaft bearing and slippage slot are without relative rotary motion, more loose fit tolerance can be adopted, so the release movement of the heat amount of stretching is more reliable, and be more conducive to control operation, structure is simple, convenient and practical.
Description
Technical field
The present invention relates to a kind of guide roller supporting bearing block, particularly relate to the supporting shaft holder being applied in and supporting deflector roll in weaving, dyeing.
Background technique
In weaving, dyeing industry, be all transport fabric with metal deflector roll, for hot blast drying class and other high-temperature heating devices, deflector roll roll body is all run under the hot environment in drying room, and the bearing support supporting deflector roll is then arranged on outside drying room.For baker, every meter of elongation is at 1 ~ 1.2mm/m when being heated to 210 DEG C for metal deflector roll, then the baker deflector roll of 2000mm fabric width is subject to thermal expansion length at about 2.5mm.If the bearing support at deflector roll two ends does not have corresponding elongation to discharge measure, the bearing deflector roll that will be stuck can not operate, and even deflector roll is supportted curved and damages.This deflector roll by phenomenon ubiquity in hot blast drying class and other high-temperature heating devices of thermal stretching, so the high-temperature hot with elongation release function stretches deflector roll positioning bearing seat very important effect and general use meaning.
The method of present more use is connected and fixed by the bearing support at deflector roll two ends, and coordinate being processed into more loose (gap) with the deflector roll spindle nose of bearing fit, when deflector roll is by thermal stretching, deflector roll spindle nose and brearing bore produce the slippage that rubs, and what discharge deflector roll is subject to thermal expansion length.According to mechanical matching standard, the spindle nose of rotary guide and the endoporus of the bearing be arranged in bearing support should adopt comparatively tight (interference) to coordinate, and guarantee bearing inner race and deflector roll spindle nose, with entering to rotate, meet the normal operation of deflector roll.
Adopt said method release deflector roll by thermal expansion length, deflector roll spindle nose and bearing inner race wear and tear because the slippage that rubs produces, after equipment use a period of time, deflector roll spindle nose and bearing inner race all may because of serious wear cisco unity malfunction.And the more difficult grasp of fit tolerance value of the method deflector roll spindle nose and brearing bore, if coordinated pine, then may because of the rotational slide of spindle nose and bearing inner race when deflector roll work rotates, the wearing and tearing of acceleration spindle nose and bearing inner race; If cooperation tension, then when deflector roll by deflector roll spindle nose after thermal stretching and bearing inner race insensitive owing to sliding, elongation can not effectively be discharged, and still can produce bearing and to be stuck or deflector roll roll body is supportted curved and damages.
Summary of the invention
The present invention is directed to above-mentioned defect, after object is to provide one that deflector roll can be made to be heated, elongation is effectively discharged, and ensures the deflector roll floating support bearing support that deflector roll runs well for a long time.
Technological scheme of the present invention is: the present invention is arranged on deflector roll two ends, and at least the bearing support of one end is slip shaft bearing.
Described slip shaft bearing comprises bearings mounted slippage bearing seat and fixed bearing, the cylindrical of slippage bearing seat offers the slippage slot with supporting axle parallel to an axis, bearing is installed with and extends in slippage slot and and the fastening piece that is slidably matched of slippage slot.
Further, deflector roll one end of the present invention is slip shaft bearing, the other end is fixed bearing block, fixed bearing block comprises bearings mounted rigid bearing pedestal and fixed bearing, the cylindrical of rigid bearing pedestal offers the locking groove axially vertical with supporting axle, bearing is installed with and extends in locking groove and and the close-fitting fastening piece of locking groove.
The present invention adopts interference fit to locate due to deflector roll spindle nose and bearing inner race, and slippage is just carried out between bearing support outer ring and slippage slot, so can not there is the wear phenomenon of spindle nose and bearing inner race in deflector roll work operation process.And further, the bearing block of Zhong You one end, deflector roll two ends is completely fixed, heat stretch slippage only bearing support at one end carry out; And the outer ring of slip shaft bearing and slippage slot are without relative rotary motion, more loose fit tolerance can be adopted, so the release movement of the heat amount of stretching is more reliable, and be more conducive to control operation, structure is simple, convenient and practical.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention
Fig. 2 is the structural representation of fixed bearing block of the present invention
Fig. 3 is the structural representation of slip shaft bearing of the present invention
In figure, 1 be fixed bearing block, 2 are slip shaft bearings, 3 are side covers, 4 are shaft block rings, 5 are bearings, 6 are bearings, 7 are fastening screw nuts, 8 are cylinder end clamping fixed screws, 9 is that heat stretches deflector roll.
Embodiment
Below in conjunction with accompanying drawing, the present invention will be further described in detail:
As shown in Figure 1, bearing 5 is loaded fixed bearing block 1, then one end spindle nose heat being stretched deflector roll 9 loads in the inner ring hole of bearing 5, axle head shaft block ring 4 is spacing fixing, loads onto side cover 3.Again fixed bearing block 1 is loaded in the bearing saddle bore of bearing 6, the cylindrical end being connected the cylinder end clamping fixed screw 8 of locating with bearing 6 stretches on fixed bearing block 1 cylindrical to be fixed with the locking groove internal locking of central axis upright, and with fastening screw nut 7, cylinder end clamping fixed screw 8 and the flat grip of bearing 6 are prevented screw loosening, complete the installation location of fixed end bearing support.
Repeat said process, stretch on slip shaft bearing 2 cylindrical with in the slippage of centerline axis parallel with the cylindrical end of cylinder end clamping fixed screw 8, Cock screw cylindrical end and groove bottom are not locked, ensure that slip shaft bearing 2 can axial slip in the slippage slot of bearing 6, with fastening screw nut 7, cylinder end clamping fixed screw 8 and the flat grip of bearing 6 are prevented screw loosening again, complete the installation location of sliding-end bearing support.
When deflector roll is by thermal stretching, due to the bearing of fixed end and bearing support all limited, deflector roll elongation all stretches to slip shaft bearing 2 end.Bearing 5 in slip shaft bearing 2 and between bearing support and guide shaft and bearing inner race be all fixed, relative movement is not had between them, and owing to only limit the motion of circumferencial direction between slip shaft bearing 2 outer ring and slippage slot, axially can free-extension.So bearing support outer ring, under deflector roll extends the promotion of axial force, is outwards located slippage, made the elongation of deflector roll be released, ensure the normal operation under deflector roll heating status.
When deflector roll is not heated, roll body can shrink again, and equally, bearing support outer ring is under deflector roll shrinks the pulling of axial force, and inside slippage, bearing support is reset to previous condition.
