Description
Technical field
The present invention relates to restorative procedure, relate in particular to the method for the online gearbox shaft bearing bore of a kind of quick reparation, belong to machinery maintenance technical field.
Background technology
At present, skid in the outer ring in running of the bearing in the online gear-box of steel rolling mill, the phenomenon of race circle occurs frequent, causes dead eye surface appearance wearing and tearing in various degree, must carry out reparation and could continue to use.A kind of processing method gear housing is transported to producer again process reparation, and this kind of method reliability is higher, but required time is long and costly; Another method is that traditionally experience increases pad below abration position, this kind of method risk is larger, if the blocked up meeting of pad causes bearing clearance to reduce burn bearing event occurs, if cross thin words not have due effect, dead eye can be caused on the contrary to wear and tear aggravate, threaten equipment security of operation.In addition, for the dismountable bearing block of part, if directly changed after the wearing and tearing of its dead eye, unnecessary waste can be caused.Particularly under steel industry production capacity surplus, overall stagnant situation, more to carry out joint Zhi Jiangben work.Therefore, for problems of the prior art, a kind of new technical scheme of exigence solves above-mentioned technical problem.
Summary of the invention
The present invention is just for the technical problem existed in prior art; there is provided the method for the online gearbox shaft bearing bore of a kind of quick reparation, the method is simple to operation, can repair the dead eye that gear-box weares and teares fast, power generating ratio loses; shorten the repair time, save maintenance cost.
In order to solve above-mentioned Problems existing, technical scheme disclosed by the invention is as follows: the method for the online gearbox shaft bearing bore of a kind of quick reparation, is characterized in that, said method comprising the steps of: step (1) checks wearing and tearing, confirms benchmark; Step (2) bearing cleaning hole processes; The process of step (3) dead eye matte finish; Step (4) secondary cleaning dead eye; Metal repairing agent is fully mixed well according to consumption by step (5) in proportion; Step (6) dead eye surface smear metal repairing agent also strikes off; Step (7) metal repairing agent solidifies; Step (8) dead eye diameter measurement reconditioning; Step (9) dead eye bearing edge guard is measured and reconditioning; Step (10) dead eye surface engagement accuracy checking reconditioning.
As a modification of the present invention, the specific practice of described step (1) checks that the diametric wearing depth of dead eye is not more than 1.0mm, and the aperture size benchmark of adjacent non-position of bearings is intact, without noticeable wear; The specific practice of described step (2) is the greasy dirt using acetone bearing cleaning hole surface, exposes metal true qualities.
As a modification of the present invention, the specific practice of described step (3) be use sanding machine progressively polish dead eye abration position and make polishing vestige undulate, the difference of height of grinding depth is not more than 0.30mm.The main purpose of this step increases adhesive force, guarantees that follow-up metal repairing agent can be combined with dead eye mother metal and firmly do not come off.
As a modification of the present invention, the specific practice of described step (4) removes the iron filings left over polishing rear surface, and again that surface clean is clean with acetone.
As a modification of the present invention, the specific practice of described step (5) selects metal to repair healant 1111, and its base-material is fully mixed with the ratio of curing agent according to volume ratio 3:1, spiral head used during mixing or putty knife stir must be guaranteed without greasy dirt and other pollutants.
As a modification of the present invention, the specific practice of described step (6) is: 61) with putty knife, the healant of mixing is spread upon dead eye abration position, smears evenly; 62) use glacing flatness and the good lining bar of surface smoothness, as slide measure, with the non-wear surface of dead eye for benchmark, both hands compress the two ends of lining bar and make its true edge be adjacent to datum hole simultaneously; 63) both hands along the circumferential direction move and strike off the healant of dead eye excess surface, and check whether surface has pit, if any, then must supplement healant at corresponding position; 64) the 62nd is repeated)-63) step, until abration position surface is basically identical with the size of datum hole.When environment temperature higher than the work of smearing when 25 DEG C should in 15 minutes end of operation, otherwise should smear within 30 minutes, preventing healant from solidifying affects repairing quality.
As a modification of the present invention; the specific practice of described step (7) is that the film that dead eye surface is clean is protected and is at room temperature cured; can solidify in 1 hour when environment temperature is more than 25 DEG C and put in place, be about 2-3 hour lower than hardening time when 25 DEG C.If the detachable and small volume of the bearing block of casing, when temperature is lower than 5 DEG C, bearing block can be put into baking oven 30 DEG C of solidifications; If when dead eye is larger, allow its spontaneous curing, also can toast around it with sunlamp, accelerate curing rate.
As a modification of the present invention, the specific practice of described step (8) is by after smooth for dead eye surface finish with 2000 order sand paper, inside diameter caliper is used to measure the aperture of dead eye, measure every 22.5 ° and record reading value, contrast with drawing standard size, if need the size of the position of reconditioning respective point again until basically identical when size is greater than standard value.
As a modification of the present invention, the specific practice of described step (9) measures with micrometric depth gauge every 22.5 ° and record the depth value of dead eye rib, contrast with drawing standard size, if need the size of the position of reconditioning respective point again until basically identical when size is greater than standard value.
As a modification of the present invention, the specific practice of described step (10) is: 11) use new bearing outer ring and smear 1 place's red lead powder at its outer surface every 120 °; 12) bearing outer ring is put in dead eye; 13) by bearing outer ring rotating 360 degrees; 14) take out bearing outer ring, and check the contact situation of dead eye and red lead powder, answer reconditioning contact zone higher point when red lead powder skewness; 15) the 11st is repeated)-14) step is until red lead powder is evenly distributed on dead eye.
Relative to prior art, advantage of the present invention is as follows, 1) this technical scheme is simple to operate, easily controls; 2) method of the online gearbox shaft bearing bore of a kind of quick reparation described in this invention, the shutdown loss that line gear case occurs because of dead eye wearing and tearing can be reduced in greatest extent, avoid gear-box to remove and be transported to producer and repair, easy to operate, the dead eye position of wearing and tearing can be repaired fast, shorten the repair time; The compression strength of the dead eye after using this technology to repair, thermal deformation coefficient, impact strength and corrosion resistance all can reach the requirement that gear-box uses online, under normal circumstances, repair position and can use more than 3 years; To repair the dead eye that aperture is 200mm, gross weight is example at the gear-box of about 10 tons, online gear-box is removed the words sending processing factory to repair, complete and resume production and at least want more than 48 hours to reparation from shutdown, if and use this method, carry out repairing, whole process is estimated can complete between 8-10 hour, resumes production; 3) this technical scheme reduces and can utilize the replacing of bearing block, saves maintenance cost, feasibility and replicability stronger.
