国产1米~3机械式单斗挖掘机的锥形离合器摩擦块原是通过两片压板用12个稳钉固定的。装配费力,工作中常出现抱死现象。改装的办法是:先将原压板稳钉用气焊割掉磨平,再将特制的小挡板(长70毫米,一端宽20毫米,另一端宽25毫米,厚5毫米)按摩擦块长度分别焊好、安装。经300小时运转,未出现过热、打滑、抱死等现象。 The cone clutch friction block of a domestic 1 m~3 mechanical single-bucket excavator was originally fixed with 12 studs via two platens. Assembling is laborious and lockup often occurs in the work. The modification method is: First, the original pressure plate is fixed by gas welding to cut off and flatten, and then a special small baffle (70 mm in length, one end is 20 mm wide, the other end is 25 mm wide, and the thickness is 5 mm) is divided according to the length of the friction block. Welded and installed. After 300 hours of operation, no overheating, slipping, locking or other phenomena have occurred.
