Rubber strip of bearing of tail shaft of submarine

Abstract

A rubber strip of a bearing of a tail shaft of a submarine is provided with a metal strip framework. A rubber layer wraps the outer side of the metal strip framework and comprises, by weight, 60 parts of Number 40 butadiene-acrylonitrile rubber, 40 parts of Number 26 butadiene-acrylonitrile rubber, 5 parts of zinc oxide, 2 parts of stearic acid, 1.5 parts of age resistors A, 2 parts of age resistors D, 10 parts of M550 carbon black, 10 parts of mixed gas carbon black, 2 parts of coumarone, 2 parts of DCP (dicumyl peroxide) cross-linking agents, 1 part of KH-570 coupling agents, 5 parts of SP antistatic agents, 10 parts of dibutyl ester, 10 parts of paraffin oil, 6 parts of graphite powder, 8 parts of carbon fibers, 5 parts of bronze powder, 5 parts of silver powder and 5 parts of molybdenum disulfide powder. The rubber layer comprises components capable of reducing the coefficient of friction, so that the coefficient of friction between the rubber layer and the steel tail shaft of the submarine is low. During usage, noise is low when the tail shaft of the submarine rotates in the insertion strip type rubber bearing. The rubber strip has the advantages that the underwater concealment of the submarine is good owing to the insertion strip type rubber bearing comprising the rubber strip, and the rubber components of the rubber strip are reasonable in composition.

Description

technical field [0001] The invention relates to a rubber slat for a fillet type rubber bearing of a submarine stern shaft, in particular to a compound composition of the rubber slat for a fillet type rubber bearing of a submarine stern shaft. Background technique [0002] The shaft is a rotating transmission part in mechanical equipment, and the bearing is a component that fixes the position of the shaft in the equipment, supports the load of the shaft and reduces the friction between the shaft and the body. Bearings include roller bearings and bushings. [0003] The submarine stern shaft is the stern shaft of the submarine. The submarine stern shaft stretches out from the rear of the submarine. The rear end of the stern shaft outside the submarine is connected to the propeller. The size of the stern shaft is large and the load is also large. The stern shaft is installed on two bearings, one is the rear bearing, the rear bearing is on the part of the hull in contact with t...

AI Technical Summary

Problems solved by technology

[0007] In the prior art, the rubber composition of the rubber slats in the strip-type rubber bearing of the submarine stern shaft is not very reasonable, and the rubber slats made of this rubber compound and the steel submarine stern shaft The coefficient of friction is not very low. During use, when the submarine stern shaft rotates in the embedded rubber bearing, the noise caused by friction is not small enough. The embedded rubber bearing of the submarine stern shaft made of this rubber strip will affect the Submarine Concealment Underwater
