Abstract
The utility model relates to a conveyor roller used in the departments of coal mines, ports, ore mines, cement, chemical engineering, thermal power generation, etc, namely a combination seal transmission turnabout drum. The turnabout drum comprises a barrel, a drum shaft and bearing pedestals at the two sides of the drum shaft. The bearing pedestals consist of pedestal bodies, right plugs and left transparent covers. Shaft sleeves are arranged between the left transparent covers and the drum shaft, and the left transparent covers are sealed with the shaft sleeves by labyrinth seal rings and metal frame seal rings. The shaft sleeves are arranged between the seal metal frames and the shaft in order to prevent the shaft from being damaged by the seal metal frames. The combination seal of the labyrinth type seal retainer rings and the seal metal frames effectively prevents pollutants from entering, makes seal more reliable and extends the service life of the drum shaft. The seal lips of the combination seal metal frames are directed at the side of the bearing, so lubricant losses are avoided, and the use cost is reduced. After the shaft sleeves are arranged, only the shaft sleeves need to be exchanged during maintenance, and the maintenance cost is largely reduced.
Description
Technical field
The utility model relates to a kind of converyor roller that is applied to departments such as colliery, harbour, mine, cement, chemical industry, thermal electric generation, i.e. the transmission of combination sealing, changed course cylinder.
Background technology
In the prior art, converyor roller comprises the bearing seat of cylindrical shell, drum shaft, drum shaft both sides, and bearing seat is made up of seat body, right close lid, the saturating lid in a left side, and a left side is lid and drum shaft sealing employing labyrinth packing or metallic framework sealing usually thoroughly.Labyrinth packing is to form with the Sealing shield ring that is arranged into the labyrinth form, reaches sealing effectiveness by long and crooked Sealing shield ring labyrinth; The metallic framework sealing is to reach sealing with sealing metal skeleton and axle direct connection.Its shortcoming is labyrinth packing, poor effect; Metallic framework sealing and axle direct contact have produced destruction to axle, cause lubricant to run off, and be bad because of bearing felt, causes under the operating mode condition of severe, and roller bearings often damages, and has increased maintenance capacity, has influenced production, has brought the certain economic loss.
The utility model content
The purpose of this utility model is that a kind of bearing seal structure more reasonably transmission, the changed course cylinder of combination sealing are provided at above-mentioned deficiency.
Technical solution of the present utility model is: the transmission of combination sealing, changed course cylinder, comprise the bearing seat of cylindrical shell, drum shaft, drum shaft both sides, and bearing seat is formed by sitting body, right close lid, the saturating lid in a left side.Be provided with axle sleeve between saturating lid in a left side and the drum shaft, labyrinth seal and metallic framework seal ring are adopted in sealing between saturating lid in a left side and the axle sleeve.In order to prevent of the wearing and tearing of sealing metal skeleton, be equipped with axle sleeve between sealing metal skeleton and the axle to axle.
The utility model has the advantages that: 1, the Sealing shield ring by the labyrinth form and the combination sealing of sealing metal skeleton, effectively prevented entering of pollutants, seal more reliably, increased life-span of drum shaft.2, combination sealing metallic framework seal lip has prevented bleeding of lubricant towards bearing one side, has reduced use cost.3, behind the installation axle sleeve, when maintenance, only need rebush, reduce the cost of maintenance greatly.
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Description of drawings
Fig. 1 is the utility model structure diagram.
Fig. 2 is a B place structure for amplifying sketch among Fig. 1.
The specific embodiment
Referring to Fig. 1,2, the transmission of combination sealing, changed course cylinder comprise the bearing seat of cylindrical shell 1, drum shaft 5, drum shaft 5 both sides, and bearing seat is made up of seat body 3, right close lid 4, the saturating lid 2 in a left side.Be provided with axle sleeve 9 between saturating lid 2 in a left side and the drum shaft 5, prevent of the wearing and tearing of the metallic framework of metallic framework seal ring 8 drum shaft 5.Labyrinth seal 7 and metallic framework seal ring 8 are adopted in sealing between saturating lid 2 in a left side and the axle sleeve 9, are combination sealing.Lubricant is a not end of annotating labyrinth dust trend, uncleanly lubricant can be cleaned out from inside to outside.Metallic framework seals 8 lips towards bearing one side, can prevent that lubricant runs off, and the lubricated of bearing place is independently, so the lubricant at bearing place cleans all the time, and does not run off.After the improvement, spatially, on the interchangeability, can both meet the demands on other operational factor.
