装载机车架铰接销受力大、润滑条件差,系易损件。有些生产厂家已改用关节轴承,较好地解决了销套过早磨损的问题。但轴向限位的可靠性却没有保证,为此我们对其进进了改进。 一、轴向限位失效的现象和后果 自1995年5月以来,送我所大修的装载机都出现起步和制动时有明显撞击感的情况,有6台还发生厂如图所示的法兰5上的固定螺钉磨损、垫板10和螺钉11脱落等现象,其中1台在修复后试机的第5天垫板和螺钉就丢失了。
Loader frame hinge pin force, poor lubrication conditions, the Department of wearing parts. Some manufacturers have switched to joint bearings, a better solution to the problem of premature wear pin sets. However, the reliability of the axial limit is not guaranteed, for which we have entered into an improvement. First, the phenomenon of axial limit failure and consequences Since May 1995, sent me to repair the loaders have shown a significant impact when starting and braking, there are 6 sets of plants as shown Flange 5 on the fixed screw wear, plate 10 and screws 11 off phenomenon, including a repair machine after the test plate on the 5th day plate and screws are lost.
