一、概况我段配属的菲得型机车,担当杭州至金华间的货运交路,已经过二十多年。该区段的线路情况是弯道多和曲线半径小,在180多公里中共有弯道144个,曲线半径在400米以下的弯道有25个,其中最小的曲线半径为249米。在这样的线路上,原用KD_7型机车,没有产生过导轮轴箱面衬磨损的问题,在应用菲得型机车后,经常产生机车导轮轴箱面衬磨损,并成为惯性现象。导轮轴箱面衬的磨损,主要表现为左、右导轮轴箱面衬同时磨耗,有时还被挤压破损。机车在厂修或架修后第一次洗修时,由于轴箱面衬磨耗,导轮
First, an overview of my paragraph is attached to the Philippine locomotive, to play the freight transport between Hangzhou and Jinhua, has been more than two decades. The section of the line situation is more curves and small radius of the curve, more than 180 km in a total of 144 curves, the curve radius of 400 meters below the curve of 25, of which the smallest curve radius of 249 meters. In such a line, the original KD_7 locomotive did not produce the problem of wear of the lining of the guide axle box. After the application of the Fiord locomotive, the locomotive wear of the lining of the locomotive guide axle box often occurs and becomes an inertial phenomenon. The wear of the guide axle box lining is mainly manifested as that the left and right guide axle box linings wear at the same time and are sometimes crushed and damaged. Locomotive repair or repair in the first repair after the repair, due to wear bearing box lining, guide wheel
