Intercommunication tuning vibration damping support type high speed gearbox

Abstract

The invention discloses a communicated tuned damping support type high-speed gear case, aiming at providing a high-speed gear case which can not only attenuate vibrations of a low frequency zone of the high-speed gear case, but also can effectively increase the attenuation and isolation effects of vibrations in the medium and high frequency zones of the gear case. The communicated tuned damping support type high-speed gear case comprises a gear case housing, an input shaft hole and an output shaft hole arranged in the gear case housing. Damping sleeves are respectively arranged inside the input shaft hole and the output shaft hole. A damping seat is further arranged at the bottom of the gear case housing. The damping seat comprises an underframe, a mounting frame and a top frame that are sequentially distributed from top to bottom. The top frame comprises a first top plate and a second top plate, and the first top plate and the second top plate are located on two opposite sides of the mounting frame. The first top plate and the second top plate are respectively connected with the underframe through vertical connecting plates. A plurality of lower damping elements is arranged between the underframe and the mounting frame; and a plurality of upper damping elements is arranged among the first top plate, the second top plate and the mounting frame.

Description

technical field [0001] The invention relates to a gear box, in particular to an intercommunication tuning vibration reduction support type high-speed gear box. Background technique [0002] The vibration and noise of high-speed gearboxes are mainly caused by the friction, vibration and collision of transmission gears. How to effectively reduce the vibration and noise of gearboxes and make them more in line with environmental protection requirements is a key research topic at home and abroad. The vibration damping element used in the traditional technology to support the gearbox at high speed is generally a vibration damping element with rubber as the main body, which attenuates the vibration energy through the elasticity of the rubber body and its own hysteresis loss. At present, with the advancement of technology, various damping components are used to support high-speed gearboxes to achieve better vibration damping and vibration isolation effects; among them, hydraulic mou...

Problems solved by technology

The hydraulic mount produces a large energy loss along the way when the liquid flows between different chambers, so that the vibration energy can be dissipated as soon as possible to achieve the purpose of damping vibration; but the current structure of the hydraulic mount is not suitable for the low frequency region Vibration can effectively reduce vibration and shock isolation, but for the vibration in the medium and high frequency region, due to the large inertia of the liquid in the flow channel between the chambers, the liquid hardly has time to flow, and it cannot be effectively used by the liquid flow. Vibration energy consumption, so it is not good for vibration isolation in the middle and high frequency areas
