一台S195柴油机,连续烧损起动轴衬套,修理费花了100多元。第一次,由于新更换的机体后衬套安装孔上方的集油凹槽内塞满了型砂,也堵住了通向后衬套油孔上边的来油孔,不但把后衬套烧损,同时还使后衬套在安装孔内转动。第二次,虽然换了新后衬套,清理了后衬套安装孔上方集油凹槽内的型砂,油路畅通了,但由于上次后衬套外径在安装孔内转动,把安装孔径磨大,垂直方向磨大0.06毫米,水平方向磨大0.04毫米,新换上的后衬套也转动,使后衬套油孔离开安装孔油孔,因润滑油流不过来而烧损。解决办法;测量安装孔的尺寸,按新尺寸绘制一张后衬套零件图,按尺寸加工一个后衬套。安装时把
A S195 diesel engine, continuous burn-start shaft bushing, repair costs spent more than 100 yuan. For the first time, due to the new replacement body bushing mounting hole above the oil collection groove filled with sand, but also blocked the hole leading to the rear bushing oil hole, not only the rear bushing burning , While also allowing the bushing to rotate within the mounting hole. The second time, although for the new liner, clean up the rear bushing mounting hole oil collection groove above the sand, the oil flow, but because the last time the outer diameter of the bushing in the mounting hole rotation, the installation Aperture grinding large vertical grinding 0.06 mm, 0.04 mm horizontal mill, the new replacement of the bushing is also rotated, so that the rear bushing oil hole hole away from the installation hole, due to the flow of oil and the loss of burning. Solution; Measure the size of the mounting hole, according to a new size of the drawing after a bushing parts map, according to the size of a rear bushing. Put it when installing
