Abstract
The utility model relates to a carrier roller, in particular to an ultra high molecular weight polyethylene carrier roller. The ultra high molecular weight polyethylene carrier roller solves the problems that an existing carrier roller is high in self weight, large in rotating resistance, poor in abrasive resistance and corrosion resistance and short in service life. The ultra high molecular weight polyethylene carrier roller comprises a pipe body, a roller shaft, two sets of supporting devices and two sets of sealing devices, wherein an inner cavity of the pipe body is sleeved with the roller shaft, the two sets of the supporting devices are symmetrically arranged between the inner side faces of the two ends of the pipe body and the outer sides of the two ends of the roller shaft in a sleeved mode, and the two sets of the sealing devices are symmetrically arranged between the outer sides of the two ends of the roller shaft and the supporting devices in a sleeved mode. Each set of supporting device comprises a bearing pedestal and a bearing, the pipe body is made of ultra high molecular weight polyethylene, and the bearing pedestal is made of modified nylon. The ultra high molecular weight polyethylene carrier roller is applied to an underground coal mine ribbon conveyer.
Description
Technical field
The utility model relates to carrying roller, specifically a kind of superhigh molecular weight polyethylene idler.
Background technology
Carrying roller is the important spare part of Belt Conveyors Underground Coal Mine, and its performance quality directly affects the operation conditions of belt conveyer.Existing carrying roller is the steel carrying roller, and its body and bearing seat are all adopted and be made of a steel.Practice shows, owing to being subject to the material properties restriction of steel, steel carrying roller ubiquity is large from great, rotational resistance, wear no resistance, corrosion-resistant, service life short problem, cause thus the operation conditions of belt conveyer not good (as the running resistance that causes belt conveyer is large, load-transfer device service life is short, big energy-consuming, range of use are little etc.).Based on this, be necessary to invent a kind of brand-new carrying roller, the problems referred to above that exist to solve existing carrying roller.
Summary of the invention
The utility model for solve existing carrying roller from great, rotational resistance large, wear no resistance, corrosion-resistant, service life short problem, a kind of superhigh molecular weight polyethylene idler is provided.
The utility model is to adopt following technical scheme to realize: superhigh molecular weight polyethylene idler, roll shaft, the symmetry that comprise body, is sheathed on tube cavity are sheathed on two groups of bracing or strutting arrangements between body two ends medial surface and the roll shaft two ends lateral surface and symmetry and are sheathed on two groups of sealing arrangements between roll shaft two ends lateral surface and the two groups of bracing or strutting arrangements; Every group of bracing or strutting arrangement includes a bearing seat and a bearing; Bearing sleeve is located between body medial surface and the outside race; Be surrounded with the first annular boss on the bearing seat lateral surface; Be surrounded with the first annular recess on the body medial surface; The first annular boss and the first annular recess cooperatively interact; Bearing seat lateral surface and the mutual interference fit of body medial surface; Bearing inner ring is sheathed on the roll shaft lateral surface; Every group of sealing arrangement includes a seal disc, one group of labyrinth type sealing ring, a back-up ring and a jump ring; Every group of labyrinth type sealing ring includes an inner seal ring and an exterior seal ring; Be surrounded with the second annular boss on the exterior seal ring lateral surface; Be surrounded with the second annular recess on the bearing seat medial surface; The second annular boss and the second annular recess cooperatively interact; Seal disc, inner seal ring, exterior seal ring, back-up ring, jump ring all are sheathed between roll shaft lateral surface and the bearing seat medial surface; Seal disc is installed on the bearing inboard; Inner seal ring, exterior seal ring, back-up ring, jump ring are installed on the bearing outside along axially being arranged in order from inside to outside of roll shaft; The body of body for adopting ultrahigh molecular weight polyethylene to become; The bearing seat of bearing seat for adopting modification of nylon to make.
During work, it is static that roll shaft keeps.Under the supporting role of bearing, body and bearing seat are rotated around roll shaft.In this process, seal disc, labyrinth type sealing ring, back-up ring, jump ring jointly play and prevent that coal dust and water from entering the effect of bearing, realized the sealing of bearing.Based on said process, compare with the steel carrying roller, superhigh molecular weight polyethylene idler described in the utility model has following advantage: one, compare with steel, the quality of ultra-high molecular weight polyethylene is lighter, thereby the deadweight of superhigh molecular weight polyethylene idler described in the utility model is less, can effectively reduce the running resistance of belt conveyer, and effectively reduces the power consumption of belt conveyer.Its two, compare with steel, ultra-high molecular weight polyethylene has superpower anti-adhesion ability, thereby the rotational resistance of superhigh molecular weight polyethylene idler described in the utility model is less, can effectively prolong the load-transfer device service life of belt conveyer.Its three, compare with steel, the resistance to abrasion of ultra-high molecular weight polyethylene is 8 times of resistance to abrasion of steel (they being 3 times of resistance to abrasion of nylon), thereby the resistance to abrasion of superhigh molecular weight polyethylene idler described in the utility model is better, can effectively prolong self service life.Its four, compare with steel, the corrosion stability of ultra-high molecular weight polyethylene is better, thereby the corrosion stability of superhigh molecular weight polyethylene idler described in the utility model is better, can effectively enlarge the range of use of belt conveyer.In sum, superhigh molecular weight polyethylene idler described in the utility model is by adopting ultra-high molecular weight polyethylene to replace steel as the material of body, and by adopting modification of nylon to replace steel as the material of bearing seat, efficiently solve existing carrying roller from great, rotational resistance large, wear no resistance, corrosion-resistant, service life short problem, thereby effectively improved the operation conditions of belt conveyer.
The utility model efficiently solve existing carrying roller from great, rotational resistance large, wear no resistance, corrosion-resistant, service life short problem, be applicable to Belt Conveyors Underground Coal Mine.
