Novel thrust bearing structure for ship

Abstract

The invention belongs to the field of thrust bearings, and particularly relates to a novel marine thrust bearing structure which comprises an upper mounting shell, a lower mounting shell is arranged below the upper mounting shell, thrust shafts are arranged on the inner side of the upper mounting shell and the inner side of the lower mounting shell, and the outer walls of the thrust shafts are fixedly sleeved with thrust rings. A supporting pad is arranged on the outer side of the thrust ring, and a thrust block is arranged on the outer side of the supporting pad. According to the novel thrust bearing structure for the ship, through the arrangement of the thrust ring and the thrust block on the outer side of the thrust ring, when the thrust ring is subjected to the thrust action of a propeller, pressure can be applied to the thrust block, so that the contact center of the thrust ring and the supporting block deviates from the integrated weight of the thrust ring, and then a wedge-shaped oil film can be formed between the thrust ring and the thrust block; the effect that the thrust rings and the thrust blocks do not make contact with each other is achieved, liquid friction is achieved, the friction force generated when the bearing rotates is reduced to a certain degree, and the problem that the friction force on the inner side of an existing device is large due to the fact that the lubricating effect is poor when the existing device rotates is solved.

Description

technical field [0001] The invention relates to the field of thrust bearings, in particular to a novel thrust bearing structure for ships. Background technique [0002] The main function of the marine water-lubricated thrust bearing is to bear the axial thrust or pull generated by the propeller and transmit it to the hull, thereby pushing the submarine forward or backward. The traditional marine water-lubricated thrust bearing is installed in the cabin, composed of upper and lower shells , Thrust shaft (including thrust plate), thrust pad, support bearing and other components. [0003] Due to the complex structure of existing marine thrust bearings, the installation cost is high and time-consuming. At the same time, the lubrication effect of the bearing is also poor, and it is easy to have high temperature after long-term work and high friction, which leads to compression resistance. low performance and low service life. [0004] In order to solve the above problems, this ...
