在罗斯托夫车辆段内,作者对KB3—型转向架摩擦减震器在修理周期内其套与销的磨损机理、磨损强度和磨损特点进行过研究。销的磨损是因套沿其表面微动而造成的,这种微动是在减震器运用过程中紧固螺母自紧时产生的。最大磨损值(在走行30万公里后沿直径的平均磨损为2.5毫米以下)是出现在与减震装置纵向中心线平行的平面内,这是因为在车辆加速制动时在摩擦减震器内存在有偏斜的缘故。车辆走行30万公里后套外径的平均磨损,按罗斯托夫车辆段的数据为每侧3.3毫米。在这种情况下,套圈出现椭圈形磨损的特征。套的最大磨损是发生在向车辆纵向中心线回转的平面内。
In Rostov’s car depot, the authors studied the wear mechanism, wear strength, and wear characteristics of the sleeve and pin of the KB3-bogie friction damper during the repair cycle. The wear and tear of the pin is caused by the fretting of the sleeve along its surface, which fretting is caused by the tightness of the tightening nut during the application of the shock absorber. The maximum wear value (average diameter of 2.5 mm below average 300,000 km traveled) appears in a plane parallel to the longitudinal centerline of the shock absorber as the frictional shock absorber memory In the slightest reason. The average wear of the outer diameter of the outer sleeve after traveling 300,000 km of the vehicle was 3.3 mm on each side according to the data of the Rostov car depot. In this case, the collar appears elliptical wear characteristics. The maximum wear of the sleeve occurs in the plane of rotation to the longitudinal centerline of the vehicle.
