Segmented Rubber Tilting Pad Thrust Bearings

Abstract

The invention provides a sectional rubber tilting-pad thrust bearing which comprises a thrusting plate and a support ring, wherein the support ring is coaxially arranged under the thrusting plate; the thrusting plate is coaxially and fixedly connected with a rotating shaft through an end plate; the sectional rubber tilting-pad thrust bearing further comprises a plurality of sectional rubber tilting-pad components which are uniformly fixed on the upper surface of the support ring at intervals; each of the sectional rubber tilting-pad components comprises a pad surface, a substrate and a sectional rubber cushion which are sequentially connected tightly from top to bottom; a gap is formed between the upper surface of the pad surface and the lower surface of the thrusting plate; the upper surface of the sectional rubber cushion is fixedly connected with the substrate through a vulcanization technique; the lower surface of the sectional rubber cushion is fixedly connected with the support ring through the vulcanization technique; the sectional rubber cushion comprises a first rubber cushion and a second rubber cushion which are distributed along a rotating direction of the thrusting plate; the thickness of the first rubber cushion is as same as the thickness of the second rubber cushion; and the hardness of the first rubber cushion is less than the hardness of the second rubber cushion. According to the invention, water can be taken as a lubricating agent and the vibration attenuation effect is excellent.

Description

technical field [0001] The invention belongs to the technical field of underwater thrust bearings, in particular to a segmented rubber tilting pad thrust bearing. Background technique [0002] Thrust sliding bearings are widely used in various types of rotating machinery such as water pumps, steam turbines, and ship propellers. They mainly rely on hydrodynamic lubrication to bear axial loads, and are key components for the stable and reliable operation of rotating machinery. With the rapid development of science and technology, people have higher and higher requirements on the vibration and noise performance of equipment. How to reduce the vibration and noise of thrust sliding bearings on the basis of ensuring effective operation is an important issue that we need to solve urgently. Ships, especially ships, have higher requirements on the vibration and noise reduction performance of thrust bearings in order to achieve the concealment effect. [0003] In addition, the leakag...

Problems solved by technology

[0003] In addition, the leakage of lubricating oil in ship oil-lubricated thrust bearings will cause serious water pollution. With the enhancement of people's awareness of environmental protection, the demand for the development of new resource-saving and environment-friendly water-lubricated bearings is becoming more and more intense.
