Method and structure for preventing heat from being transmitted to damper

The invention discloses a method and structure for preventing heat from being transmitted to a damper. A final stage of output shaft connected with the damper is provided with a heat insulation assembly composed of a pressing ring and a heat insulation ring; and heat transfer is blocked by the heat insulation assembly, so that the temperature of the damper is kept within the normal working range.A high-intensity material with the heat conduction coefficient being 0.3 W/m.DEG C and the heat resisting temperature being 450 DEG C is made into the heat insulation ring, and a high-intensity titanium alloy material with the low heat conduction coefficient is made into the pressing ring. Under the condition that it is ensured that the temperature of the damper is kept within the normal work range, the heat insulation ring and the pressing ring have good intensity and machinable performance, and precision matching between the heat insulation assembly and the damper can be ensured; and extra materials are prevented fr
