Embodiment Construction

[0024] The present invention will be described in detail below in conjunction with the accompanying drawings, as shown in the figure: the tilting pad type water-lubricated rubber alloy bearing of this embodiment includes a shaft housing 1, bearing pads 2 uniformly distributed in the shaft housing 1 along the circumferential direction and fixed The rubber alloy lining 3 bonded to the inner side of the bearing bush 2 generally has more than 3 bearing bushes. This embodiment adopts 5 bearing bushes, and the inner wall of the axle housing 1 is fixed with supports arranged axially and uniformly distributed along the circumferential direction. Bar 4, the support bar 4 corresponds to the bearing bush 2 one by one, the top cross section of the support bar 4 is circular, the outer side of the bearing bush 2 is provided with an axial groove 2a with a circular cross section, and the top gap of the support bar 4 Cooperate with the embedded groove 2a to form a tiltable structure in which th...

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,...
