矿山工业中,破碎各类矿石使用各类大、中、小型旋回破碎机。大型初碎和二次破碎旋回破碎机轴套上的巴氏合金采用浇铸法上挂。由于作用在轴承上大的静载荷和这种破碎机设计时考虑的较大的强度安全系数,需选用含锡量高的巴氏合金ъ83浇铸偏心轴承。最初,巴氏合金层是在专用机床上用堆焊的办法上挂在偏心轴套的光滑表面上。根据使用堆焊巴氏合金的偏心轴套的经验,可以看出,由于分层、龟裂和剥落,轴承会很快脱层。为了提高巴氏合金与偏心轴套金属表面的
In the mining industry, various types of ore are crushed and used in various large, medium and small gyratory crushers. Large pre-crushing and crushing gyratory crusher on the bushes of pasteurized alloy casting method. Due to the large static load acting on the bearings and the greater strength and safety factor considered in the design of this type of crusher, a high-content pasteurized eccentric bearing should be used. Initially, the Babbitt layer was mounted on a smooth surface of an eccentric sleeve by means of surfacing on a dedicated machine. Based on the experience of using overlay Babbitt’s eccentric bushings, it can be seen that the bearings delaminate very quickly due to delamination, cracking and spalling. In order to improve the surface of the metal with the eccentricity of the babbitt
