Abstract

The invention provides a flexible production process of wheel drive maintenance. The process comprises five procedures of A, B, C, D and E, each process corresponds to maintenance of one type of locomotive wheel drive, a utilization rate of elements such as station equipment, human resources, sites and the like is increased to the maximum extent by searching the same or similar aspects of all locomotive types in a wheel drive maintenance process, sharing the same station or overhauling in the same area, and overhauling sites are saved.

Description

technical field [0001] The invention relates to the technical field of locomotive wheel drive maintenance, in particular to a flexible production process for wheel drive maintenance. Background technique [0002] With the change of locomotive maintenance regulations and the reduction of cost, it is necessary to carry out research on the maintenance process of wheel drive devices in order to ensure that the cost of locomotives in a maintenance cycle is reduced, the quality is improved, the maintenance cycle is shortened, and the production efficiency is improved. During the research process, it is necessary to continuously optimize the process, improve the quality, and achieve the effect of cost reduction and efficiency increase. In the overhaul of HXD1 and HXD3 series locomotive wheel drives, the two series of locomotives are quite different in structure and process, and the existing overhaul production line is not universal and cannot adapt to various specifications of loco...
