The invention discloses a traction machine vibration isolation system. The system comprises a lower bearing structure, a composite vibration isolation table, a height adjusting component and an uppercoupling structure, wherein the lower bearing structure, the composite vibration isolation table, the height adjusting component and the upper connecting structure are sequentially connected from bottom to top and are separately distributed on the two sides of a traction machine base; the upper coupling structure comprises steel profiles on the front and rear vertical surfaces of the traction machine base and force bearing components on the left side and the right side of the traction machine base, and connecting profiles provided with round holes are arranged at the end parts of the steel profiles and the force bearing components; and a bottom nut of the height adjusting component is welded to the composite vibration isolation table, a screw rod on the bottom nut passes through a circularhole in a connecting component, a lower self-locking nut is arranged on the lower portion of the round hole, an upper self-locking nut is arranged on the upper portion of the round hole, and the self-locking nut is rotated to jack up the traction machine base. The load of the traction machine base can be independently borne by a machine room floor, or jointly borne by additional steel cross beamsand traction machine bearing steel beams, or independently borne by the traction machine bearing steel beams. According to the three structural forms, the vibration isolation and noise reduction transformation project of the elevator traction machine can be completed without disassembling the traction machine.
