The invention discloses a kind of repair method of flywheel crackle, it is related to machinery manufacturing technology field；Comprise the following steps：V-shape groove is polished along crack orientation, in the beginning and end position holes drilled through of crackle, some grooves are outputed on the both sides of crackle, groove length exceedes the half of crack depth across crackle, its depth；Bore the blind hole of even number respectively in the groove of crackle both sides, blind hole is using crackle as line of symmetry；The spur of some inverted u-shapeds is made, the distance of two nail pins of spur is equal with the pitch-row of blind hole；The spur is loaded in the blind hole；Weldering is filled to V-shape groove, groove, through hole respectively with welding rod, until filling up；All weld seams of cracks polish to smooth.The present invention can be solved the problems, such as after flywheel current weld line using crackle still occurs after a period of time.
Description
Technical field
The present invention relates to machinery manufacturing technology field, especially a kind of repair method of flywheel crackle.
Background technology
Flywheel be mounted in bent axle one end have compared with large rotating inertia part, be the common part of machinery industry it
One, the main function of flywheel is to store the energy and inertia outside engine expansion stroke, therefore, the working environment of flywheel be all
In high rotating speed and the frequent switching of the slow-speed of revolution；Again because flywheel is manufactured by the relatively low cast iron of the trade mark, so, longevity of service
Afterwards, flywheel is easily because fatigue damage goes out crackle, if cracked flywheel can be broken, scrap without repairing quickly；Mesh
Before, the method for repairing and mending of cast iron flywheel crackle in the art is usually：Cracks are first polished into groove, groove position carried out pre-
Heat, then cylinder iron welding rod is filled weldering to groove, finally by weld grinding；The repair method of this crackle can only prolong
The long flywheel life-span still new crackle can occur in the beginning or end of crackle for a period of time, after flywheel work a period of time, it is necessary to
Repair again；So for several times after, flywheel will be unable to be repaired again, can only scrap.
The content of the invention
It is an object of the invention to provide a kind of repair method of flywheel crackle, after it can solve flywheel current weld line
The problem of using crackle still occurs after a period of time.
In order to solve the above problems, the technical solution adopted by the present invention is：The repair method of this flywheel crackle, including with
Lower step：
A, V-shape groove is polished along crack orientation, the angle of V-shape groove section is 55 ° ~ 65 °, and groove depth exceedes crackle
Depth；
B, in the beginning and end position holes drilled through of crackle, the through-hole diameter is 10 ~ 15mm；
C, some grooves are outputed on the both sides of crackle, the groove length exceedes the one of crack depth across crackle, its depth
Half；
D, the blind hole of even number is bored respectively in the groove of crackle both sides, the blind hole is using crackle as line of symmetry；
E, the spur of some inverted u-shapeds is made, the distance of two nail pins of the spur is equal with the pitch-row of the blind hole；
F, the spur is loaded in the blind hole；
G, weldering is filled to V-shape groove, groove, through hole respectively with welding rod, until filling up；
H, all weld seams of cracks are polished to smooth.
In above technical scheme, further scheme can be：The welding rod is EZCQ electrode for cast irons.
By adopting the above-described technical solution, the present invention has the advantages that compared with prior art：
1st, the present invention slots on crackle both sides and punched, and is put into inverted u-shaped spur in hole, holds crackle, then carry out repair welding；
2nd, this repair method of the present invention can improve the intensity of mend, greatly prolong flywheel service life.
