Abstract
The utility model relates to a carrier roller sealing device, a set of end face sealing device is respectively and sequentially arranged at two ends of a carrier roller barrel body, and the set of the end face sealing device is composed of a bearing, a bearing base, a lower sealing piece, an upper sealing piece, a sealing top cover and a shaft clamp. An upper end face of a cylinder protruding in the middle of the upper sealing piece is provided with a plurality of ring grooves, the cross sections of the ring grooves are tooth-shaped, the ring grooves are matched with the sealing top cover in tiny gap mode, and accordingly a first maze sealing is formed. A plurality of annular concave-convex grooves are arranged between the upper sealing piece and the lower sealing piece and between the lower sealing piece and the bearing ring, the upper sealing piece and the lower sealing piece are matched to form a second maze sealing, and the lower sealing piece and the bearing ring are matched to formed a third maze sealing. The first maze sealing transforms and dissipates flow kinetic energy through kinetic energy, the second maze sealing and the third maze sealing mainly adopt a method of increasing number of bending to consume the flow kinetic energy through friction drag effect of mazes, and finally achieving the aim of blocking the flow from further flowing to a next maze, thereby effectively protecting the bearing in a carrier roller and facilitating prolonging of service lives of the carrier roller and the belt conveyor. The carrier roller of the carrier roller sealing device can be widely applied to mines, docks, enterprises and the like and used as bulk material transportation devices.
Description
Affiliated technical field
The utility model relates to a kind of sealing arrangement of belt roller end face.Especially a kind of carrying roller sealing arrangement of establishing labyrinth packing at the carrying roller two ends.
Background technology
At present, coal, iron and steel, industries such as chemical industry mostly adopt belt roller to transport continuously in the transport process of large bulk material, this belt transport unit generally is made up of roller shell and bearing that is placed in one and the minor axis that passes their centers that metal or rubber are made, because these belt transport units generally all are to place open-air use, expose to the sun and rain for a long time, the roller shell of being made by metallic material or rubber is corrosion or aging easily, its working environment very severe of while, if roller bearing end cap only adopts simple the covering, dust and water are easy to invade the lubricating system of Idler bearing, thereby cause bearing loss, influence whole belt transport unit mode of operation.In a word, existing these belt roller face seals simplicity of design, poor reliability, easily aging and corrosion, leak tightness is poor, influences transmission efficiency and the work life and the safe in operation under special particular surroundings of whole belt roller and conveyer.
Summary of the invention
In order to overcome the defective of existing belt roller face seals, the utility model provides a kind of and is made by composite material, and processing is simple, the special labyrinth shape carrying roller sealing arrangement of structure, and it can improve the service life of carrying roller and band conveyor effectively.
The technical scheme that its technical matters that solves the utility model adopts is: each adorns a cover in order by bearing at the two ends of carrying roller cylinder, bearing seat, lower seal, back seal spare, the face seals that top pressure closure and axle card are formed, top pressure closure in this face seals, lower seal and axle interference fit, constitute the static seal body by the axle card with the bearing inner ring axial restraint, keep transfixion in the work, back seal spare, bearing seat and cylindrical shell are fixed by interference fit and are constituted the dynamic seal body together, work natural axis bearing outer-ring rotates together, back seal spare outside face is made the circular conical surface groove of indent, when carrying roller cylinder rotates, the centnifugal force that rotation produces throws away sticking to water on the carrying roller end face or the dust conical suface along back seal spare, the cylinder upper surface design of back seal spare intermediate projections is several profiles of tooth cross section annulus groove and cooperates the formation first road labyrinth packing with the top pressure closure minim gap, when the fluid of certain ambient pressure or certain speed is invaded, because the tolerance clearance of back seal spare and top pressure closure is very little, add the big wedge angle tooth in the labyrinth, first road, small volume of fluid enters the crown gap by compression, speed increases, and then enter profile of tooth cross section annulus groove cavity, volume increases suddenly, speed moment decline, by thermomechanical effect, kinetic energy is converted into thermal dissipation, back seal spare and lower seal, lower seal and bearing seat cooperate formation second road and the 3rd road labyrinth packing by several annular concavo-convex groove of design, because it is very little to enter the fluid velocity of the second road labyrinth packing, so second road, the 3rd road labyrinth packing mainly adopts the way that increases number of bends to utilize the frictional resistance effect of labyrinth packing to consume its fluid dynamic energy, deepen the crooked degree of depth in first road simultaneously, and the design of its inside face is the conelet degree face of cylinder, when the dynamic seal body is subjected to external load, labyrinth clearance low-angle off-centre, fluid during rotation in this gap of periodic extruding, reach the obstruction fluid and further flow into the purpose in Xia Dao labyrinth, thereby effectively the carrying roller end face is sealed.
The beneficial effects of the utility model are: owing to adopted three road labyrinth packings; the possibility that makes fluid on the carrying roller end face enter in the bearing in the carrying roller reduces greatly; thereby improved protection, helped improving the service life of carrying roller and band conveyor bearing.
