Abstract

The invention disclose a manufacturing method of a bearing bush of a sliding bearing. According to the manufacturing method, the thixotropic characteristic that Babbitt metal semi-solid slurry flows during extrusion and keeps a solid state during standing is utilized, the Babbitt metal semi-solid slurry has the heap plasticity in the deposition process, a Babbitt metal layer structure with the high deposition thickness can be achieved, the Babbitt metal semi-solid slurry has the high liquid phase fraction, metallurgical bonding is adopted between plastic stacking layers, multi-layer deposition can be carried out according to the thickness of the needed babbitt metal layer structure, the production efficiency is far higher than that of an electric arc additive manufacturing method and a casting technology, and meanwhile, the tool cost and the machining allowance needed by a traditional casting technology are greatly reduced. Ultrasonic vibration is adopted to act on a semi-solid deposition layer in the plastic stacking process, distribution of alloy components and hard spot phases is homogenized, the internal quality and interlayer bonding quality of the Babbitt metal layer structure are improved, and therefore, the bearing bush production is achieved with high quality and high efficiency.

Description

technical field [0001] The invention relates to the technical field of mechanical manufacturing, in particular to a method for manufacturing a bearing shell of a sliding bearing. Background technique [0002] With the rapid development of my country's transportation manufacturing industry, mining industrial machinery equipment, metallurgical equipment and energy power units and other machinery manufacturing industries and the rapid improvement of the national defense industry's technological level, the requirements for high precision and long-term efficient operation of mechanical transmission structures are getting higher and higher. , the sliding bearing is a key component supporting the operation, because of its high load capacity, high precision and good retention during high-speed operation, superior shock absorption performance, low operating noise, smooth operation and long-term effective life, it is widely used in the above mechanical equipment . Tin-based Babbitt all...
