PC1616锤式破碎机是矿山主要机械设备,用于石炭石二次破碎。该设备自1981年投产以来,曾多次发生轴承内圈转动、轴颈磨损和咬伤,至使主轴失效报废。从1983年到1987年,由于轴承和主轴发生故障,一对轴承使用寿命最长为一年,最短为51天。更换一次轴承和主轴少则停产4天,多则7天,影响正常生产。为此,改进了配合公差,提高了轴承和主轴的使用 PC1616 hammer crusher is the main machinery and equipment for the second crushing of carbon stone. The device has been put into operation since 1981, there have been many bearing inner ring rotation, journal wear and bite, so that the spindle failure retirement. From 1983 to 1987, due to bearing and spindle failure, the longest bearing life of a year, a minimum of 51 days. Replace the bearing and spindle at least discontinued for 4 days, as many as 7 days, affecting the normal production. To this end, improved tolerances and increased use of bearings and spindles
