Description
Technical Field
The utility model belongs to the technical field of the axle sleeve, concretely relates to self-lubricating excavator axle sleeve.
Background
The rotating arm and the supporting shaft of the excavator are often assembled by adopting a shaft sleeve. The excavator is usually used for excavating work, lubricating grease can slowly run off in the using process, the conditions that the rotation is inflexible, the rotation resistance moment is large and even the rotation cannot be carried out often occur between the shaft sleeve and the supporting shaft, the lubricating grease needs to be replaced in time, and if the lubricating grease is not replaced in time and corresponding measures are taken, the gap between the bearing and the shaft is continuously enlarged until the condition of abrasion occurs; however, the grease in the conventional sleeve is oxidized and deteriorated, and therefore, the grease cannot be mixed with new grease because the grease contains a large amount of organic acids and impurities. Therefore, when the lubricating grease is replaced, the old lubricating grease on the parts is cleaned, and then new lubricating grease can be added again.
An effective solution to the problems in the related art has not been proposed yet.
