A ship water-lubricated stern bearing with automatic equalizing function

Abstract

The invention discloses a water-lubricated ship stern bearing capable of realizing automatic load balancing. The stern bearing comprises an inner rubber layer, a first metal shaft sleeve layer, a second metal shaft sleeve layer, a self-adaptive material layer and a third metal shaft sleeve layer from inside to outside in sequence, wherein the self-adaptive material layer is distributed between the second and third metal shaft sleeve layers; the thickness of the self-adaptive material layer changes in a gradient manner along the axial direction of the stern bearing; the stern bearing is adaptively cured and formed with the oblique degree of a ship stern shaft. The invention further discloses the materials and embodiments of work specifications of the self-adaptive material layer, the metal shaft sleeve layers and the inner rubber layer. According to the water-lubricated ship stern bearing capable of realizing automatic load balancing, the rubber layer at the inner side of the water-lubricated stern bearing is uniformly stressed; the bearing has the characteristics of compact structure, operation convenience and automatic load balancing; the control difficulty of abnormal abrasion noise of an existing ship stern bearing is effectively solved.

Description

technical field [0001] The invention belongs to the technical field of ship vibration reduction and noise reduction, and more specifically relates to a ship water-lubricated stern bearing with an automatic load balancing function. Background technique [0002] For ships, the problem of abnormal stern noise will appear to varying degrees under low-speed operating conditions, which will affect the physical and mental health of the crew, and may also adversely affect their sailing performance. The research results show that the abnormal noise at the stern of the ship is not only related to the water lubricating material, but also closely related to the structure of the stern bearing itself. [0003] The water-lubricated stern bearings of ships in the prior art usually use water-lubricated rubber bearings with rubber inside and metal structure outside, specifically as figure 1 As shown in , the design of the inner rubber structure of the stern bearing is mainly based on the ave...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the above defects or improvement needs of the prior art, the present invention provides a ship water-lubricated stern bearing with automatic load equalization function, in which the key components, structures, setting methods and working specifications of the stern bearing are adjusted according to the application characteristics of the stern bearing. The improvement can make the rubber layer on the inner side of the water-lubricated stern bearing more uniform in force. At the same time, it has the characteristics of compact structure, easy handling and automatic load balancing, which can effectively solve the problem of controlling abnormal friction and noise of the existing ship stern bearing.
