Abstract
The wink robin static balance technology of the present invention, theoretical foundation is enriched reliable, it is easy to operate, supported using existing plant bottom case plus two one steel rails, or support is made using original axis of rolling, machine parts connecting shaft is lifted, using instant rotation method, balanced to machine parts, the correctness of balance can be grasped at any time, test the force of rolling friction that can calculate test specimen rapidly, weighting amount, laid particular stress on position, and provide remaining unbalanced value.
Description
This wink robin static balance technology is the checkout facility to the segregation of machine components quality, and the quality for machine components is entangled
Partially, flight-line maintenance category is belonged to.
The static balance of machine components, method is early rotated freely, method is on special specific supports, rotates freely machinery
In the week of part 2 to 3, after part tapers off rotation, seeing part, which is directed downward, it is assumed which orientation is laid particular stress on.Lay particular stress on more
It is fewDo not know.With regard to examination plus counterweight, then rotate again, then add counterweight.So again and again, very hello is tremnbled, also inaccurate, person
Blind person's climbing method.It is tiring, finally do not know unbalance residual content is how many yet.This balancing method must must have a special branch
Frame, and this no support of many equipment users, therefore this static balance is can not do, thus many abrasions, deformation, the machine of corrosion
Device part, it cannot balance, repair, can only be operating only haltingly, cause the great person, equipment breakdown, the loss of personal property brought
It is very big.
It is an object of the invention to provide a kind of without support, position, weighting amount once are laid particular stress on regard to that can predict, and can know that
Unbalance residual content is how many, allows be the people oneself balanced and know whether and meets design requirement.The technical measures that we take are
Supported using existing plant bottom case plus two one steel rails, or support is made using original axis of rolling, machine parts is connected
Axle lifts, and using instant rotation method, is balanced to machine parts.
Wink robin static balance technology is described further below in conjunction with accompanying drawing, wherein Fig. 1 is test specimen initial graph, and Fig. 2 is extremely
Fig. 5 is respectively the figure of 1~procedure position of procedure position 4：
1 does the quartering on the excircle of test specimen, and indicates 1,2,3,4 on each Along ent successively, then is made on each point
Go out to hang the prominent or recessed object of test mass.As shown in Figure 1.
2 tested parts are given rise on the rail on bearing block, make 2,4 two points on test specimen can not into level, such as test specimen
Come to a complete stop, then the front shift-up iron that need to be rolled in test specimen, make 2,4 two points on test specimen into level.As shown in Fig. 2 (procedure position 1),
Added an examination of on point 2 heavy.It is first big after small, last refinement sand, until test specimen occurs to stop during instantaneous roll.Record test mass ω2Numerical value.
3 do not take test mass ω2, remove buting iron, recover at 2,4 two points into level, as shown in Fig. 3 (procedure position 2), then
Stop when additional examination weight rolls to test specimen on point 4, record test mass ω4Numerical value.
4 90 ° of test specimen rotate counterclockwises, make on test specimen can not be come to a complete stop into level, such as test specimen at 1,3 two point, also need to be in test specimen
The front of rolling adds buting iron, makes 1,3 two point on test specimen into level.It is heavy in the additional examination of point 1 as shown in Fig. 4 (procedure position 3), extremely
Test specimen occurs to stop during instantaneous roll, and records test mass ω1Numerical value.
5 do not take test mass ω1, remove buting iron, recover at 1,3 two point into level, as shown in Fig. 5 (procedure position 4), then
Additional examination weight to test specimen occurs to stop during instantaneous roll on point 3, records test mass ω3Numerical value.
The force of rolling friction of 6 test specimens
Q=(ω1+ω2+ω3+ω4)/4
The weighting value of 7 test specimens
The weighting point of 8 test specimens, between two less examination weights, the examination from minimum aggravates point recently, and this is minimum
Examination aggravates point 3, center of circle O and weighting point W and enclosed in an angle
Sin α=(ωa-QIt is minimum)W
9 plus counterweight be not lay particular stress on point on, but with lay particular stress on point symmetry excircle on.Match somebody with somebody if can not add on excircle
Weight, can add counterweight, but to increase the quantity of counterweight in outer inside circumference.
The 10 test specimen remnants unbalanced values Jing Guo counterweight, if meet design requirement, do not meet such as, it is desirable to above-mentioned
Experiment is done one time again.As remaining unbalanced value is less than design requirement, then static balance terminates.
January nineteen eighty-three, the rolling mill of Tong-Hua Steel Factory factory 650 change gear mesh, and little gear is two sections of shaft gears that flywheel is housed,
Gear wheel weighs 23 tons, the remaining unbalanced value requirement of flywheel is less than 0.5 kilogram, the remaining unbalanced value of gear wheel directly through 3.2 meters
It is required that less than 10 kilograms, be visually inspected that gear wheel is thick on one side, and thin on one side, quality segregation is serious, but can not determine how much, it is necessary to
Being balanced to be used, but factory no one can do this balance at that time, and after repeated discussions, finally this task is pressed to peace
Certain engineer at dress.By the balance at two days two nights of the engineer, a flywheel adds 0.5 kilogram of counterweight, and gear wheel adds counterweight 314
Kilogram, beyond more than 30 times of permissible value.After start, milling train operates steadily, and thick roll-force increases, and it is successful to illustrate balance.Only
Whole year production task is just completed with half a year.Make a profit instead of suffering a loss, get a profit 12,000,000 yuan, later 09 months 3 years profits increase, and fill from this
Divide the power for showing mill balancing.
There are many equipment being operating only haltingly in China, and some have impact on normal production, cause economic loss, and some leads to pernicious
Personal safety accident, reason be no one can this balance, some is without balance bracket, some no one's meetings.Wink robin is quiet flat now
Weighing apparatus technology is made public, gear wheel, the flywheel of rolling mill, the blower fan of agglomerates of sintered pellets, the hydraulic turbine, the boat warship of hydroelectric generation
Ship flywheel, impeller, without balance bracket with regard to that can balance, society, economic implications are very big.
