Abstract

PURPOSE: To reduce noise of a rotor by mounting a runner on shaft end of the rotor at the driven side and disposing this runner in oil.
CONSTITUTION: A runner 9 is mounted on a shaft end 8 of a rotor 3 at the driven side and disposed in an oil chamber 10 formed by a casing 1 and cover 5. Thus, the movement of the runner 9 is slowed down by the viscous resistance of oil so that it can not follow up to about 60W300Hz frequency of vibration. Hence, the fluctuation of rotation in the rotor caused by the fluctuation of torque of a screw rotor can be absorbed to reduce the noise of the rotor.
