Description

Technical Field

[0001] The utility model relates to the technical field of bearing seats, and more specifically, to a drum bearing seat with high protection performance. Background Art

[0002] Stacker reclaimers and reclaimers are used in large ports, power plants, coal mines, etc. During the reclaiming process of the stacker reclaimer, the drum located at the head of the equipment's hanging belt is very close to the coal pile, resulting in a large amount of coal powder filling the area near the drum bearing seat. The traditional drum bearing seat has poor sealing and is difficult to effectively block the infiltration of coal dust, resulting in the contamination of lubricating grease and greatly shortening the bearing life.

[0003] After retrieval, the prior art CN201746066U discloses a conveyor drum applied to departments such as coal mines, ports, mines, cement, chemical industry, and thermal power generation, including a cylinder body, a drum shaft, and bearing seats on both sides of the drum shaft. The bearing seat is composed of a seat body, a right end cover, and a left through cover. A shaft sleeve is provided between the left through cover and the drum shaft, and a labyrinth seal ring and a metal skeleton seal ring are used for sealing between the left through cover and the shaft sleeve. To prevent the sealing metal skeleton from wearing the shaft, a shaft sleeve is installed between the sealing metal skeleton and the shaft. Through the combined sealing of the labyrinth-shaped sealing ring and the sealing metal skeleton, the entry of pollutants is effectively prevented, the sealing is more reliable, and the service life of the drum shaft is increased. The combined sealing metal skeleton has the sealing lip facing the bearing side to prevent the loss of lubricant and reduce the use cost. After installing the shaft sleeve, only the shaft sleeve needs to be replaced during maintenance, greatly reducing the maintenance cost.

[0004] In the solution provided by the above prior art, through the setting of a single-layer seal, the protection effect on the bearing is not good, and at the same time, the bearings inside the bearing seat will be blocked for a long time. It is not only difficult to find the accurate position when manually adding lubricant to the bearing, but also there will be a waste phenomenon of lubricant. A drum bearing seat with high protection performance is needed to solve this problem. Summary of the Utility Model
