Abstract
One kind combination regulation bearing pin, including outer shaft, outer shaft outer surface is provided with positioning step, outer shaft and interior between centers pass through conical surface A radial fits, outer shaft is provided with wide 2-4mm groove along longitudinal direction, pull bar is inserted in interior axle and head is at the big end of the conical surface of interior axle, the pull bar other end and nut 8 are screwed, it is close to the conical surface small end end face of outer shaft in the left side of nut, during nut axial tightening, along coordinating, the conical surface is relative to be slided outer shaft with interior axle, and then support swollen outer shaft, outer shaft outer ring is set to swell, meet outer ring and the quality of fit requirement of sector-segment frames and the connecting-rod bearing of bearing pin, to realize functional requirement radially with axially quick precise match;During dismounting, pull bar is unclamped, interior axle is beaten, interior axle is released along the conical surface, outer shaft because interior axle swell active force reduce or disappear and reduced outside diameter, increase outer shaft and coordinate between fit clearance, reduce dismounting hinge pin resistance, be easy to dismounting hinge pin;Present invention reduction repair density, lifting bearing pin installation or removal efficiency, extends bearing pin service life.
Description
Technical field
The present invention relates to metallurgy industry continuous casting technology field, other machinery equipment field is equally applicable to, more particularly to a kind of solution continuous casting segment bearing pin installation adjusts bearing pin with dismantling a kind of combine that be difficult and researching and developing.
Background technology
In the fan-shaped segment structure clamped using pitman pin mode, equipment through running after a while, and dismounting hinge pin is extremely difficult, blows the failure mode processing cut more than user using oxygen rifle, repairs long in time limit, damage of facilities degree is big, is unfavorable for the maintenance and repair of continuous casting installation for casting.The principal element for causing dismounting hinge pin difficult has two, on the one hand because being caused some corrosion phenomenas by high-temperature steam and covering slag, and these rusty stains gather obstruction bearing pin with other dust collection and extracted.On the other hand it is the presence that fan-shaped section clamp system gives clamping force or the lower pressure of upper framework deadweight generation, bearing pin is there is pulling force, the frictional resistance that increase bearing pin is extracted in the dismounting stage.
Therefore exploitation can realize the cooperation requirement of Fast Installation positioning, and the bearing pin of the fast quick-detach of energy, just seem extremely necessary.
The content of the invention
In order to overcome the defect of above-mentioned prior art, it is an object of the invention to provide one kind combination regulation bearing pin, the cooperation requirement of Fast Installation positioning can be realized, and the bearing pin of the fast quick-detach of energy, repair density is reduced, lifting bearing pin installation or removal efficiency extends bearing pin service life.
In order to achieve the above object, the present invention is realized in:
One kind combination regulation bearing pin, including outer shaft 7, the outer surface of outer shaft 7 is provided with positioning step 10, pass through conical surface A radial fits between outer shaft 7 and interior axle 6, outer shaft 7 is provided with wide 2-4mm groove 9 along longitudinal direction, pull bar 5 is inserted in interior axle 6 and head is at the big end of the conical surface of interior axle 6, and the other end of pull bar 5 and nut 8 are screwed, and the conical surface small end end face of outer shaft 7 is close in the left side of nut 8.
Use of the present invention can realize that rapid axial substitutes traditional single bearing pin with the special construction built-up shaft form that radial positioning is installed.Built-up shaft is mainly made up of outer shaft 7, interior axle 6 and the part of pull bar 5 three, and outer shaft 7 is designed with positioning step 10 according to the positioning requirements of axle, realizes accurate axially position;Interior axle is matched somebody with somebody with outer between centers using the conical surface, by interior axle core screw rod axial tightening when, along coordinating, the conical surface is relative to be slided outer shaft with interior axle, and then support distending has the outer shaft of longitudinal notch, outer shaft outer ring is set to swell, the outer ring quality of fit requirement of bearing pin is met, to realize functional requirement radially with axially quick precise match.During dismounting, pull bar is unclamped, interior axle is beaten, interior axle is released along the conical surface, outer shaft because interior axle swell active force reduce or disappear and reduced outside diameter, increase outer shaft and counterpart fit clearance, reduce dismounting hinge pin resistance, be easy to dismounting hinge pin.
Brief description of the drawings
The schematic diagram that Fig. 1 uses cooperatively for the present invention with other equipment.
Fig. 2 is structural representation of the invention.
Embodiment
The invention will now be described in detail with reference to the accompanying drawings.
Reference picture 1, Fig. 2, one kind combination regulation bearing pin, including outer shaft 7, the outer surface of outer shaft 7 is provided with positioning step 10, and outer shaft 7 coordinates according to bearing pin to be needed to be designed with the diameter of axle for coordinating step and different cooperation requirements, passes through conical surface A radial fits between outer shaft 7 and interior axle 6, outer shaft 7 is provided with wide 2-4mm groove 9 along longitudinal direction, pull bar 5 is inserted in interior axle 6 and head is at the big end of the conical surface of interior axle 6, and the other end of pull bar 5 and nut 8 are screwed, and the conical surface small end end face of outer shaft 7 is close in the left side of nut 8.
The present invention operation principle be:
Reference picture 1, combination bearing pin 4, the oscillating bearing on connecting rod 1 and sector-segment frames 2 of the invention cooperate, and are pressed against bearing pin on axial locating surface to the left by axle end baffle plate 3.When tightening nut 8, outer shaft 7 and interior axle 6 will be along conical surface A relative movements be coordinated, and outer shaft 7 is swollen, and stop the rotation nut 8 when reaching radial fit required precision, and the present invention just reaches that wide arc gap is put into pilot hole, and the purpose that tight fit is realized in gap is reduced in adjustment.In dismounting, unclamp nut 8, beat the small cone end of interior axle 6, the present invention is set to be exited to the left along the conical surface, the power elimination that swells inside outer shaft 7, the radial dimension of outer shaft 7 diminishes, and increases outer ring of the present invention and the fit clearance of sector-segment frames 2 and bearing baffle 3, advantage is provided for present invention taking-up, fast quick-detach is realized.Repeatedly dismantled on the surface of outer shaft 7 abrasion diminish or processing error in the case of, made up by the precession number of turns increase of nut 8, extend service life of the present invention, the loss of reduction bearing pin.
