Squeeze oil film damper with double layers of oil films and double supports

Abstract

The invention discloses a squeeze oil film damper with double layers of oil films and double supports. The squeeze oil film damper comprises supporting covers, a floating ring, an asynchronous motor and three oil sealing packing rings; the floating ring comprises a cylindrical ring body, a support part extending outward from one end of the ring body and a retracing part which extends backward fromthe top end of the support part in a retracing mode; and the retracing part is in a cylindrical shape as well, and the retracing part forms an elastic structure relative to the ring body through thesupport part. The floating ring is provided with a retracing type elastic supporting structure which is installed on an oil film outer ring. The far end of the installing side uses one oil sealing packing ring, the oil films at the near end of the installing side are separated into two layers, and the internal oil film and the external oil film are separated by one packing rings correspondingly. According to the squeeze oil film damper with the double layers of the oil films and the double supports, the ring body, the support part and the retracing part form a retracing type elastic support which can improve the damping property of the squeeze oil film damper, the problem that an oil film inner ring and an oil film outer ring of a traditional squeeze oil film damper impact and rub and loseefficacy is solved, verification and correction of a simulation model are facilitated, and testing data support is provided for the engineering application of the squeeze oil film damper.

Description

technical field [0001] The patent of the present invention relates to an extruded oil film damper for an aero-engine damping component. Background technique [0002] Squeeze oil film dampers are widely used in the rotor parts of aero-engines for vibration reduction of rotor parts. With the development of the aviation industry, the structure of aero-engines is becoming more and more complex, and the vibration problems of rotor parts are becoming more and more prominent. Traditional Squeeze oil film dampers are difficult to meet the requirements of vibration reduction. Traditional squeeze oil film dampers are prone to failure in practical applications, and the inner and outer rings are prone to rubbing. [0003] Therefore, a new technical solution is needed to solve the above problems. Contents of the invention [0004] The purpose of the invention is to solve the problem that the pressure of the inner layer oil film is difficult to measure in the test research of the float...
