Abstract
The utility model relates to a carrier roller, in particular to an inflaming retarding antistatic polyurethane carrier roller. The inflaming retarding antistatic polyurethane carrier roller solves the problems that an existing carrier roller is large in dead load, large in rotation resistance, poor in abrasive resistance and corrosion resistance and short in service life. The inflaming retarding antistatic polyurethane carrier roller comprises a pipe body, a roller shaft arranged in an inner cavity of the pipe body in a sleeved mode, two sets of supporting devices symmetrically arranged between the inner side faces of the two ends of the pipe body and the outer side faces of the two ends of the roller shaft in a sleeved mode and two sets of sealing devices symmetrically arranged between the outer side faces of the two ends of the roller shaft and the two sets of supporting devices in a sleeved mode. Each set of supporting device comprises a bearing seat and a bearing. The pipe body is made of polyurethane and each bearing seat is made of polyurethane. The inflaming retarding antistatic polyurethane carrier roller is suitable for an underground coal mine belt type conveyor.
Description
Technical field
The utility model relates to carrying roller, specifically is a kind of flame-retardant and anti-static polyurethane carrying roller.
Background technology
Carrying roller is the important spare part of belt conveyer under the 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 all adopt steel to make.Practice shows, owing to be subjected to the material properties restriction of steel, steel carrying roller ubiquity is big from great, rotational resistance, wear no resistance, corrosion-resistant, service life short problem, cause the operation conditions of belt conveyer not good thus (as the running resistance that causes belt conveyer is big, load-transfer device weak point in service life, big energy-consuming, range of use are little etc.).Based on this, be necessary to invent a kind of brand-new carrying roller, to solve the problems referred to above that existing carrying roller exists.
Summary of the invention
The utility model for solve existing carrying roller from great, rotational resistance big, wear no resistance, corrosion-resistant, service life short problem, a kind of flame-retardant and anti-static polyurethane carrying roller is provided.
The utility model is to adopt following technical scheme to realize: flame-retardant and anti-static polyurethane carrying roller, roll shaft, the symmetry that comprise body, is sheathed on tube cavity are sheathed on two groups of bracing or strutting arrangements and the symmetrical two groups of sealing arrangements that are sheathed between roll shaft two ends lateral surface and the two groups of bracing or strutting arrangements between body two ends medial surface and the roll shaft two ends lateral surface; 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 first annular boss on the bearing seat lateral surface; Be surrounded with first annular recess on the body medial surface; First annular boss and 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 seal circle, a back-up ring and a jump ring; Every group of labyrinth seal circle includes an inner seal ring and an exterior seal ring; Be surrounded with second annular boss on the exterior seal ring lateral surface; Be surrounded with second annular recess on the bearing seat medial surface; Second annular boss and 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 polyurethane to make; The bearing seat of bearing seat for adopting polyurethane 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 seal circle, back-up ring, jump ring play jointly 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, flame-retardant and anti-static polyurethane carrying roller described in the utility model has following advantage: one, compare with steel, the quality of polyurethane is lighter, thereby the deadweight of flame-retardant and anti-static polyurethane carrying roller described in the utility model is littler, can effectively reduce the running resistance of belt conveyer, and effectively reduces the power consumption of belt conveyer.Its two, compare with steel, polyurethane has superpower anti-adhesion ability, thereby the rotational resistance of flame-retardant and anti-static polyurethane carrying roller described in the utility model is littler, can effectively prolong the load-transfer device service life of belt conveyer.Its three, compare with steel, the resistance to abrasion of polyurethane be steel resistance to abrasion 3-5 doubly, thereby the resistance to abrasion of flame-retardant and anti-static polyurethane carrying roller described in the utility model is better, can effectively prolong self service life.Its four, compare with steel, the corrosion stability of polyurethane is better, thereby the corrosion stability of flame-retardant and anti-static polyurethane carrying roller described in the utility model is better, can effectively enlarge the range of use of belt conveyer.In sum, flame-retardant and anti-static polyurethane carrying roller described in the utility model is replaced steel as the material of body and bearing seat by adopting polyurethane, efficiently solve existing carrying roller from great, rotational resistance big, 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 big, wear no resistance, corrosion-resistant, service life short problem, be applicable to belt conveyer under the coal mine.
