Technique for manufacturing high-carbon steel thrust sliding bearing of high-power low speed diesel engine

Abstract

The invention relates to a manufacturing craft of high carbon steel thrust sliding bearing for high power low speed diesel engines, belonging to a field of thrust sliding bearing manufacturing craft for large mechanical equipment. The process steps are as follows: roughcast manufacturing: roughcast pouring surface processing (decarburization processing, shot peening and rinsing): hot dip coating tin; pouring babbit alloy; machining and censoring. The manufacturing craft of high carbon steel thrust sliding bearing for high power low speed diesel engines has the advantages of simple technique, convenient operation, low production cost, good production safety, high degree of bonding for alloy layer of the finished products, less babbit alloy consumption, satisfied working requirement of the high carbon steel thrust sliding bearing for high power low speed diesel engine, wide application range in large mechanical equipment, in particular to oil tanker, large freighter and other high powerlow speed diesel engines with high load.

Description

technical field [0001] The invention belongs to the technical field of manufacturing thrust sliding bearings of large mechanical equipment, in particular to a manufacturing process of thrust sliding bearings for high-power low-speed diesel engines. Background technique [0002] Thrust sliding bearings are mechanical components used to axially locate and support shaft parts, and make relative sliding between bearing surfaces and bear axial loads to prevent axial movement of shaft parts. As a key basic component, it is widely used in large mechanical equipment such as electric motors, generators, internal combustion engines, gas turbines, and mining machinery. High-power low-speed diesel engines are widely used in the field of ships, especially high-load ships such as oil tankers and large cargo ships, due to their high load capacity, low fuel consumption, low pollution, and compact structure. The performance of the thrust sliding bearing has a direct impact on the performanc...

Problems solved by technology

However, due to the high carbon content of gray cast iron, it is difficult to enamel and cast Babbitt alloy on gray cast iron by using the traditional process of casting Babbitt alloy on low carbon steel. Therefore, the domestically produced gray cast iron thrust sliding bearings have Low bond strength, prone to problems such as shelling, loose defects, edge defects, fatigue fracture, and low life
