摘要 针对煤矿机械常处于粉尘颗粒多、工况复杂的环境中导致的设备过快磨损、铰接点锈蚀抱死和机构失效的问题,介绍了镶嵌式固体自润滑轴承和粉末冶金烧结型自润滑轴承2种固体自润滑轴承的特点和主要技术指标,阐述了固体自润滑轴承在掘锚机铰接耳、改向链轮和锚杆机钻架上的应用,为煤矿机械不良润滑部位提供了有效的解决方案。 Aiming at the problems of excessive wear of equipment, corrosion of hinge points and mechanism failure caused by coal mine machine in the environment with many dust particles and complex working conditions, introduced the characteristics and main technical indicators of two solid self-lubricating bearings, such as inlaid solid self-lubricating bearings and powder metallurgy sintered self-lubricating bearings. The application of solid self-lubricating bearings in the articulated ears of bolter miner, redirection sprocket and bolter drill frame was expounded, which provides effective solutions for poorly lubricated parts of coal mine machine.
