粘着(胶合、咬焊)磨损是两个相互作用的表面接触压力过大,润滑不良,使润滑油膜无法形成或形成的油膜被挤破,致使摩擦热急增,温度急剧上升,在高温高压下,摩擦表面的接触点发生粘连而被撕裂,被撕裂的粘连点在分子引力和摩擦阻力作用下发生位移粘附到其它接触表面,由此引起的破坏现象,称为粘着磨损。东方红—54/75拖拉机曲轴因烧瓦而发生的抱轴现象就是一种典型的粘着磨损。(一) 一些统计数字近几年来,东方红—54/75拖拉机曲轴的粘着磨损比较常见。使轴瓦早期损坏;主轴瓦座磨损,严重者则使整个汽缸体报废;轴颈表面硬度降低,耐磨性变差;曲轴发生变
Adhesion (bonding, bite welding) wear is the interaction of the two surfaces of the contact pressure is too large, poor lubrication, the film can not be formed or formed oil film is squeezed, resulting in rapid increase in friction heat, the temperature rose sharply under high temperature and pressure , The friction surface of the contact point of adhesion and was torn, tear adhesion point in the molecular gravitation and friction resistance displacement adhesion to other contact surfaces, the resulting damage, known as adhesive wear. Dongfanghong -54 / 75 tractor crankshaft occurred due to the phenomenon of burning axle is a typical adhesive wear. (A) some statistics In recent years, Dongfanghong -54 / 75 tractor crankshaft adhesion wear is more common. So early damage to the bearing; spindle bearing wear, in severe cases, the entire cylinder scrapped; journal surface hardness decreased, poor wear resistance; crankshaft change
