Tilting-pad water-lubricated rubber alloy bearing

Abstract

The invention discloses a tilting-pad water-lubricated rubber alloy bearing, wherein a bearing pad adopts a tilting type, and the structure allows the water-lubricated rubber alloy bearing to form a more stable wedge-shaped pressure water film; during operation, the tilting pad can adjust a rotor center automatically with the differences of rotating speed, load, and bearing water film thickness; a plurality of water wedges are formed around a shaft journal; the suspension operation of the shaft is realized by the wedge-shaped pressure water film; the force condition of the shaft is improved; the bearing is not easy to wear; and the energy consumption is reduced; when the shaft is affected by external disturbance, the tilting pad can swing around a fulcrum with the disturbance of the shaft; new balance is reached rapidly, and stable operation of the shaft is recovered rapidly; the operation stability of the bearing is effectively improved; therefore, the invention can effectively prolong the service life of the water-lubricated rubber alloy bearing, reduce the vibration and noise of bearing operation, and save using cost.

Description

technical field [0001] The invention relates to a bearing, in particular to a water-lubricated rubber alloy bearing. Background technique [0002] Mechanical transmission devices, especially various friction pairs in ship propulsion systems, are often composed of metal components and mineral oil is used as a lubricating medium. It consumes a lot of strategic resources such as mineral oil and precious metals. In order to prevent oil leakage, it needs to be sealed, making its structure quite complicated, and it is difficult to reduce or reduce the inevitable friction, wear, vibration, impact, noise, noise, etc. Function consumption. In the transmission system, there are still problems such as poor reliability and short life, especially the increasingly serious situation that the environment of rivers, lakes and seawater is polluted by oil leakage from the seal. [0003] In the shipping industry, according to statistics from relevant departments of the Ship Inspection Bureau,...

Problems solved by technology

[0004] In the prior art, the bearing shell of the water-lubricated rubber alloy bearing is made integrally with the shaft shell and fixed. During operation, due to the unbalanced force and torque, the shaft center is whirling at a certain frequency, resulting in a large friction, wear, vibration and noise
