一种铁水车转向架的复合固体润滑轴承

Composite solid lubrication bearing of bogie of hot metal car

Abstract

本实用新型公开了一种铁水车转向架的复合固体润滑轴承,包括轴承外圈、轴承内圈以及设置在轴承外圈和轴承内圈之间的滚珠;铁水车的轴承通过轴承外圈固定在轴承座上,轴承座固定在转向架横梁上;轴承外圈上开设有若干用于嵌入复合固体润滑剂的孔。本实用新型通过滚珠的运动将复合固体润滑剂带到内外圈之间起到润滑作用。这种经过特殊处理的轴承使用寿命提高3倍;润滑材料节省6倍以上;机械维修次数减少3倍;使轴承箱的漏油状况自动治理;运行温度比原来降低5-17度。可让免除转向架轴承的定期加油润滑维护的工作环节,降低了使用维护成本。
The utility model discloses a composite solid lubrication bearing of a bogie of a hot metal car. The composite solid lubrication bearing comprises a bearing outer ring, a bearing inner ring, and balls which are arranged between the bearing outer ring and the bearing inner ring; a bearing body of the hot metal car is fixed on a bearing pedestal through the bearing outer ring; the bearing pedestal is fixed on a bogie cross beam; a plurality of holes which are used for embedding a composite solid lubricant are formed in the bearing outer ring. According to the composite solid lubrication bearing, the a composite solid lubricant is put between the inner ring and the outer ring for lubrication through the movement of the balls. Through the special treatment, the service life of the bearing is prolonged by three times, a lubrication material is saved by more than 6 times, the mechanical maintenance frequency is decreased by three times, the oil leakage of a bearing box can be automatically treated, and the running temperature is reduced by 5-17 DEG. According to the composite solid lubrication bearing, the regular lubrication maintenance link of the bogie bearing can be saved, so that the use cost and the maintenance cost are reduced.
