A kind of installation method of torsion vibration absorber, including
1) oscillator of predetermined amount is added into each accommodating chamber of inertia rings, end cap lid is then closed into opening in accommodating chamber
Oral area and fixation form vibration absorption unit；
2) vibration absorption unit is put into the ring cavity of shell, then lid closing lid plate and fixation；
3) ring cavity is vacuumized by the through-hole of cover board, silicon is injected into ring cavity by through-hole again after vacuumizing
Oil, finally with blocking the through-hole.
The present invention can be effectively reduced the twisting vibration of engine crankshaft by the design of vibration absorption unit, compact-sized, peace
Dress is convenient, in addition, damper unit can be effectively reduced belt pulley for traditional vibration reducing measure purely using inertia rings
Overall weight, and damper unit also have the characteristics that quickly it is corresponding.
