Description
Technical field
The present invention relates to cold rolling mill mechanical equipment service technique, the online replacing bearing construction method of particularly a kind of cold rolling electroplating or continuous annealing set sinking roller.
Background technology
Rise the nineties in 20th century, China gone into operation successively many cold rolled continuous annealing units, zinc-plated unit, bethanizing unit and zinc-plated unit, each unit all has tens sinking rollers, bearing is equipped with at the roller two ends, bearing is positioned at bearing seat, in mechanical seal cover and the dynamic and static ring of mechanical seal are housed, and with the holding-down bolt support fixation in basic ground.Because unit band steel maximum operational speed reaches more than the 400m/min, the roller rotating speed is high, so wear-out of a bearing is very fast, needs often to change.At present, all be to shut down the back the roller overall pulling down, off-line is changed bearing, and labour intensity is big; The dismounting time is long, causes compressor emergency shutdown for up to more than 5 hours, and production is long non-cutting time, influences unit production efficiency.
Summary of the invention
The technical problem to be solved in the present invention is that existing bearing replacing construction method labour intensity is big, and floor time is long, provides a kind of cold rolling electroplating or continuous annealing set sinking roller online replacing bearing construction method.The online replacing bearing of the present invention's energy reduces labour intensity, shortens floor time, enhances productivity.
The present invention realizes according to following step: a kind of cold rolling, plating or the online replacing bearing construction method of continuous annealing set sinking roller, described replacing bearing construction method comprises the steps:
A, the coating bath of unit or the mechanical seal outer cover on the tank can prevent that liquid is excessive in a large number in the groove, and micro-seepage solution is concentrated discharging by pipeline.After removing the mechanical seal outer cover, throw off mechanical sealing linkage ring and stationary ring;
B hangs over bottle gouard moved by hands on the steel structure that cell body is installed or cell body welds one group of suspension centre, hitches rod, opens bearing gland, removes circular nut and circular nut stop washer;
C, the holding-down bolt of the bearing seat of dismounting sinking roller uses and draws sign indicating number that bearing seat and bearing integral are left behind;
D, bearing seat disintegrates, bearing cleaning seat and submerged roller shaft head;
E is pack into bearing seat and bearing seat is in place of new bearing;
F refuels to bearing, returns dress circular nut stop washer, circular nut and bearing gland;
G after removing bottle gouard moved by hands, hangs steel wire according to the sectional center target, and the verification steel wire, and rocking arm is installed on the roller head, uses rocking arm to measure and adjusts sinking roller squareness;
H, mechanical sealing static ring and roller gap keep evenly, with rotating ring and stationary ring friction face applying and fastening, return the dress outer cover and connect the pipeline that catchments.
If when need changing the transmission side bearing, described step a after He before the step b, need to remove the versatile spindle Safety hood, take over tie bolt, with drawing the catcher of yard leaving behind; Need back the attaching hand after the step h, connect the versatile spindle catcher, return the dress Safety hood.
When described step c removes holding-down bolt, only unclamp the jackscrew of bearing seat one side, after replacing bearing, time dress bearing seat are finished, can adjust the roller squareness by the jackscrew of fine setting bearing seat both sides, and need not adjust the concentricity of roller and motor.
Not impaired because of hitting for the protection bearing, to bearing seat, bearing uses electric induction heater to heat to described step e in advance with new bearing installation, can only hit bearing inner sleeve during construction and makes new bearing in place.
Described step e bearing seat returns dress must be rapidly, within promptly 1 minute, otherwise do not utilize bearing installation in place.
The center target of described step g is arranged on fore side, and according to different units, the squareness of sinking roller is 0.05mm/m～0.10mm/m.
The present invention utilizes bottle gouard moved by hands to hang the sinking roller, does not need sinking roller integral body is pulled down, and simplifies step, and has reduced labour intensity.When removing holding-down bolt, only unclamp the jackscrew of bearing one side, changing bearing, behind time dress bearing seat, adjust the roller squareness, need not adjust the concentricity of roller and motor, reduced work capacity, shortened the engineering time by fine setting bearing seat both sides jackscrew.So the present invention can shorten 2～3 hours repair times, shortens the compressor emergency shutdown time greatly, reduce and produce non-cutting time, improved the production efficiency of unit.
The specific embodiment
Further provide the specific embodiment of the present invention below: a kind of cold rolling, plating or the online replacing bearing construction method of continuous annealing set sinking roller, described replacing bearing technology comprises the steps:
A removes the coating bath of unit or the mechanical seal outer cover on the tank, throws off mechanical sealing linkage ring and stationary ring;
B hangs over bottle gouard moved by hands on the steel structure that cell body is installed or cell body welds one group of suspension centre, hitches rod, opens bearing gland, removes circular nut and circular nut stop washer, roller integral body need not be pulled down, and has saved the time of reinstalling;
C, the holding-down bolt of the bearing seat of dismounting sinking roller uses and draws sign indicating number that bearing seat and bearing integral are left behind;
D, bearing seat disintegrates, bearing cleaning seat and submerged roller shaft head;
E, bearing need use electric induction heater heating in advance, can only hit bearing inner sleeve during construction and make the new bearing bearing seat of packing into, and bearing seat is in place;
F refuels to bearing, returns dress circular nut stop washer, circular nut and bearing gland;
G after removing bottle gouard moved by hands, hangs steel wire according to the sectional center target, and the verification steel wire, and rocking arm is installed on the roller head, uses rocking arm to measure and adjusts sinking roller squareness;
H, mechanical sealing static ring and roller gap keep evenly, with rotating ring and stationary ring friction face applying and fastening, return the dress outer cover and connect the pipeline that catchments.
Regulate the time that squareness, concentricity spent in order to save, when described step c removes holding-down bolt, only unclamp the jackscrew of bearing seat one side, after replacing bearing, time dress bearing seat are finished, can adjust the roller squareness by the jackscrew of fine setting bearing seat both sides, and need not adjust the concentricity of roller and motor, can save time 1～2 hour.
Described step h bearing seat returns dress must be rapidly, and within promptly 1 minute, otherwise the bearing cooling does not utilize bearing installation in place.
The center steel plate of described step g is arranged on fore side, and according to the different unit of being changed, the squareness of sinking roller is 0.05mm/m～0.10mm/m.
If need to change the transmission side bearing, described step a after He before the step b, need to remove the versatile spindle Safety hood, take over tie bolt, with drawing the catcher of yard leaving behind; Need back the attaching hand after the step h, connect the versatile spindle catcher, return the dress Safety hood.
