Two ends of the upper and lower cutter shafts are respectively hinged on a rack gearbox through a float-end bearing seat and a fixed-end bearing seat, wherein a first cylindrical-hole cylindrical roller bearing and a conical-hole cylindrical roller bearing are arranged in the float-end bearing seat; the first cylindrical-hole cylindrical roller bearing is positioned on the inner side of the float-end bearing seat while the conical-hole cylindrical roller bearing is positioned on the outer side of the float-end bearing seat; inner and outer rings of the two bearings are separated through a first spacer sleeve and a second spacer sleeve in the middle; the inner ring of the conical-hole cylindrical roller bearing is expanded with the upper and lower cutter shafts through a first bearing sleeve; the outer rings of the first cylindrical-hole cylindrical roller bearing and the conical-hole cylindrical roller bearing are compressed and fixed through a first bearing gland bush; the float-end bearing seat and the upper and lower cutter shafts are sealed through a first oil seal and a second oil seal; and lubricating grease is injected into a sealed space. The spiral transverse cutting machine using the structure has good supporting rigidity of the cutter shaft structure and low deflection, enhances the running accuracy of the cutter shaft and enables the cutter shaft structure to become more compact.
Description
Technical field:
The present invention relates to the packaging paper product field of mechanical technique, refer in particular to a kind of cutter shaft structure for spiral transverse cutting machine.
Background technology:
Transverse cutting unit is an extremely important unit on the corrugated paper board production line, and at present, known Rolling Cut Machine cutter shaft structure is to be made up of last cutter shaft, following cutter shaft, bearing block, bearing, bearing gland etc.The supporting form of cutter shaft axle head has very big influence to rigidity, the circular runout of cutter shaft, the too small too early wearing and tearing that then can cause blade in upper and lower edge of a knife gap, and excesssive gap then can't cut paper.Because the spiral transverse cutting machine cutter shaft is to receive the symphyogenetic major axis of radial and axial load.So generally should not adopt the supporting structure that two ends are fixed or move about in two ends.Two ends are fixing then can not to compensate the length variations that causes because of thermal deformation, and moving about then in two ends can not axial location, accurately tool setting of the helix of the cutter edge of a knife up and down.In addition, an end is the other end structure of moving about fixedly, and the stiff end of upper and lower cutter shaft also should not cause cutter edge of a knife helix reversal deformation up and down not in the same side during because of variations in temperature, causes up and down cutter edge of a knife gap to be strengthened and can't cut paper or interfere because of the edge of a knife and bump cutter.
Summary of the invention:
The objective of the invention is to overcome the deficiency of prior art, provide a kind of supporting rigidity good, amount of deflection is little, and the cutter shaft running accuracy is high, cutter shaft few cutter shaft structure for spiral transverse cutting machine of beating.
Be to realize above-mentioned purpose, technical scheme provided by the present invention is: a kind of cutter shaft structure for spiral transverse cutting machine, it includes upper and lower cutter shaft, the end bearing seat that moves about, stiff end bearing block.Upper and lower cutter shaft two ends are hinged on the frame gear-box through move about end bearing seat and stiff end bearing block respectively, and upper and lower cutter shaft all adopts the fixedly other end structure of moving about of an end, and stiff end is at homonymy.Move about and be provided with the first cylindrical hole cylinder roller bearing and conical bore cylinder roller bearing in the end bearing seat; It is inboard that the first cylindrical hole cylinder roller bearing is positioned at the end bearing seat that moves about; The conical bore cylinder roller bearing is positioned at the end bearing seat outside of moving about; The middle inside and outside circle of separating two bearings through first spacer and second spacer; Overlap swelling through clutch shaft bearing between the inner ring of conical bore cylinder roller bearing and the upper and lower cutter shaft, and through first stop washer and the locking of first round nut, the outer ring of the first cylindrical hole cylinder roller bearing and conical bore cylinder roller bearing is fixed through the clutch shaft bearing gland; Move about and pass through first oil sealing and second oil sealing sealing between end bearing seat and the upper and lower cutter shaft, inject lubricating grease in the space after sealing;
Be provided with the second cylindrical hole cylinder roller bearing and conical bore self-aligning roller bearing in the described stiff end bearing block; It is inboard that the second cylindrical hole cylinder roller bearing is positioned at the stiff end bearing block; The Internal and external cycle of the second cylindrical hole cylinder roller bearing is respectively through first back-up ring and second back-up ring location; The conical bore self-aligning roller bearing is positioned at the fixed bearing block outside; The conical bore self-aligning roller bearing keeps at a certain distance away through the step of stiff end bearing block and the step and the second cylindrical hole cylinder roller bearing of upper and lower cutter shaft; Pass through the second bearing holder (housing, cover) swelling between the inner ring of conical bore self-aligning roller bearing and the upper and lower cutter shaft, and through second stop washer and the locking of second round nut, the outer ring of conical bore self-aligning roller bearing is fixed through second bearing gland; Through the 3rd oil sealing and the 4th oil sealing sealing, inject lubricating grease in the space after sealing between stiff end bearing block and the upper and lower cutter shaft.
On described move about end bearing seat and the stiff end bearing block joint and oil pipe are installed all.Wherein, oil pipe one end is connected on the joint, and the other end is connected on the outer lubricating cup of gear housing.
The described clutch shaft bearing cover and second bearing holder (housing, cover) can be bearing removal cover or bearing adapter sleeve.
The present invention is after having adopted said structure; Because upper and lower cutter shaft two same side have all been used the bearing block of same structure, can make expanding with heat and contract with cold of upper and lower cutter shaft to the flexible same size of same axial direction, because bearing holder (housing, cover) has all been used at two ends; The end-play that can adjust upper and lower cutter shaft bearing easily is to desired value; The circular runout of cutter shaft is reduced greatly, supporting rigidity is good, amount of deflection is little, improved the running accuracy of cutter shaft, makes cutter shaft structure compact more, thereby the service life that has prolonged the transverse cutting unit blade with make the cardboard otch neatly bright and clean; After having used the grease lubrication bearing, prevented the leakage of gear lubricant.
