Abstract

The invention relates to the technical field of engine manufacturing and machining, in particular to a milling method for a floating disc end face oil wedge. A rough turning process is carried out on a part for two times, large allowance is removed, an inner hole, an outer circle and end faces are respectively turned, a finish turning process is carried out on the part for two times, the inner hole, the outer circle, the end faces and process steps are respectively turned, grinding and lapping procedures are used, the end faces and the inner hole are machined, the ground inner hole serves as the standard, the outer circle is subjected to finish turning, oil grooves, chip grooves, wear termination lines and 20-degree process U-shaped positioning grooves of the two end faces are milled, the milled oil wedge face is polished to Ra0.4, the outer circle is subjected to the finish turning process, vapor deposition is carried out on the part, and the size of the part is rechecked. Through the above steps, the machining quality stability and machining quality of the floating disc end face oil wedge face are improved.

Description

technical field [0001] The invention relates to the technical field of engine manufacturing and processing, in particular to a method for milling an oil wedge on the end face of a floating disk. Background technique [0002] In order to ensure compliance with the emission requirements of the International Maritime Organization, various OEMs have embarked on the development of dual-fuel engines. Because liquefied natural gas has the advantages of good economy and low emissions, it has become the focus of research. In recent years, a new generation of dual-fuel engine technology is expanding from medium-high speed engines to low-speed engines. For this two-stroke dual-fuel engine, it is necessary to break through the design of high-flow and high-pressure ratio high-efficiency compressors, high-expansion ratio and high-efficiency turbine design, etc. Technology, thus the processing difficulty of the product has invisibly increased. [0003] At present, the processing method of...
