Description
Technical field:
The utility model relates to a kind of belt transport unit, band conveyor carrying roller in the industries such as especially a kind of mine, harbour, metallurgy, coal.
Background technology:
At present, industries such as coal, iron and steel, mine, harbour, metallurgy, chemical industry mostly adopt belt to transport continuously in the transport process of large loose unpacked material, the carrying roller that uses on this belt transport unit generally adopts iron and steel material quality system with forming, because steel carrying roller weight greatly, easily get rusty, the corrosion of chemical industry such as not acid and alkali resistance, salt material, the specific wearability height, service life is short, change frequently, the damage of carrying roller has also strengthened the wearing and tearing to belt; The carrying roller that also useful earthenware pipe is made, but because bearing felt is unreliable, it is not firm to fix, makes dust and water electrode easily enter bearing inside, thereby cause bearing loss, influence the mode of operation of belt transport unit, greatly reduce enterprises production efficiency.
The utility model content:
The utility model provides a kind of band conveyor carrying roller, and it is simple in structure, and is wear-resisting, corrosion stability is high, in light weight, bearing felt is solid and reliable, long service life, guarantee the normal operation of belt transport unit, improved the production efficiency of enterprise, solved problems of the prior art.
The utility model is to solve the problems of the technologies described above the technical scheme that is adopted to be: it comprises ceramic roller, is located at the composite plastic bearing seat at ceramic roller two ends, and with the coaxial steel pivot shaft that is installed on the composite plastic bearing seat of ceramic roller; Composite plastic bearing seat inside be equipped with successively from inside to outside inner shield ring, sealed bearings, composite plastic oil box and outside back-up ring, the outside of back-up ring is provided with the composite plastic end cover outside, is provided with the end cover anti-drop device in the outside of composite plastic end cover; Inwall at ceramic roller evenly is laid with at least three grooves, be provided with on the outer wall of composite plastic bearing seat with the ceramic roller inwall on the tongue that is sealed and matched mutually of groove.
Described end cover anti-drop device is a spring card.
Groove on the described ceramic roller inwall is communicated with the ceramic roller two ends.
The tube of described ceramic roller is thick to be 5～40mm; Overall diameter is 80～160mm.
Described composite plastic bearing seat is polyvinylchloride or polyethylene bearing seat.
The utility model is simple in structure, the cylindrical shell sealing, dustproof, antistatic properties is good, wear-resisting, the corrosion stability height, the composite plastic bearing seat is installed in employing at the ceramic roller two ends, on the composite plastic bearing seat outer wall tongue be sealed and matched mutually with groove on the ceramic roller inwall, make ceramic roller and composite plastic bearing seat location more accurate, in composite plastic bearing seat inside inner shield ring is installed at first from inside to outside, inner shield ring and bearing seat compress, form sealing, make the inner hollow structure that forms of carrying roller, this structure can make carrying roller in operational process, produce vibrations at random, make belt be stained with thing and drop voluntarily, the not sticking carrying roller of inhaling, hollow structure has alleviated the carrying roller overall weight simultaneously, alleviated the pressure of carrying roller, prolonged carrying roller service life sealed bearings and bracing frame; By inner shield ring sealed bearings, composite plastic oil box and outer back-up ring outwards are installed successively, this structure makes sealed bearings separate with the generation of ceramic roller in-to-in hollow structure, strengthened bearing seat in-to-in leakproofness, the leakage problem of lubricating grease when having prevented long-time the running on the one hand, prevent foreign matter on the other hand, enter bearing inside as dust, sewage etc., can make the axis of rolling be under the whole sealing status running for a long time, prolong carrying roller service life; At the arranged outside end cover anti-drop device of composite plastic end cover, can prevent to come off when the composite plastic end cover from turning round for a long time, guarantee the safety and the stability of carrying roller operation.
