Abstract
The present invention provides a super-hybrid composite machine roller sleeve which adopts a layer composite structure. The present invention is composed of a functional layer (1) and a structure layer (2). The material used for the present invention comprises glass fibers, steel fibers, carbon fibers, synthetic fibers and reinforced polymer base composite mixed fabrics. The present invention has the advantages of light weight, high strength, high rigidity, corrosion resistance, wear resistance, good antistatic performance, flame resistance, safe use, electricity saving, etc.
Description
The present invention relates to a kind of machine rolle rsleeve made from superhybrid composite.Be applicable to all kinds of band conveyors, can satisfy the technical requirements of different purposes.
Band conveyor is that departments such as coal, mine, saltern, steel plant, cement mill extensively adopt a kind of continuous Transport Machinery, both can be used for the level transportation, can be used for tilting transportation again, fed distance is generally 300-3000 rice, and its running resistance is little, and traffic capacity is big, consumption of current is economized, and safe and reliable.Carrying roller, drive roll, reversing roller are its main parts.Wherein the carrying roller of consumption maximum can be divided into flute profile upper supporting roller, parallel snub pulley, aligning carrier roller, impact idler by purposes.Above-mentioned various roller assembles by parts such as sleeve, center shaft, ball (post) bearings.Therefore, sleeve is one of vital parts of conveyer, and the used sleeve of existing band conveyor generally processes with solid drawn pipe, and its weight is big, starting difficulty, to drag consumption of current big; Easy-to-rust, service life is short; Big, the mobile difficulty of its weight.
The objective of the invention is to: at the existing deficiency of iron and steel sleeve, according to composite property can appropriate design principle, different purposes, different technologies requirement by sleeve, select for use assorted fibre to strengthen polymer matrix composite, adopt corresponding forming process, make the composite material sleeve now have abrasion performance, intensity height, in light weight, good rigidity, performance such as antistatic concurrently.
The present invention is achieved in that the structure of superhybrid composite sleeve holds the thick cyclinder in (seat) hole for the two ends tape spool.Sleeve adopts layer composite structure (seeing accompanying drawing 1).The skin of barrel is functional layer (1), with wear-resisting, the withstanding corrosion that guarantees sleeve, technical performance such as antistatic.The barrel functional layer is Structural layer (2) with in, to guarantee sleeve enough intensity, rigidity is arranged, and can satisfy the load bearing requirements of each roller effectively.Bearing (seat) hole (3) is established at two ends, so that bearing is installed.The structure of the lightweight roll sleeve that load-bearing is little is seen Fig. 2: Q-1, Q-2.
The used superhybrid composite (surperhybrid composite) of the present invention is through rationally designing, allocate, combining by reinforcing material, basis material, this three classes material of functional material.Its reinforcing material is glass fibre, steel fiber, carbon fiber, syntheticfibres and respective fabric thereof etc.; Basis material is a thermosetting resin; Functional material has high-abrasive material, antifriction material, toughening material, conductive material and antistatic additive, fire proofing etc.
Functional layer of the present invention (1) but prescription in need to add wear-resisting accordingly, antifriction, toughness reinforcing, conductive material antistatic additive, both made it improve resistance to abrasion, reduce friction coefficient, can have antistatic property concurrently again; To specific (special) requirements person is arranged, this layer can adopt electrodeposition of metals, carbon fiber winding layer, the carbon fiber winding layer, make sleeve antistatic, fire-retardant, wear-resisting, increase four kinds of rigidity or two or more fortifying fibre and mix and strengthen thermoset or thermoplastic resin matrix.Still needing in this prescription adds fire proofing, high-abrasive material, to improve resistance to abrasion, the flame resistance of sleeve long-term use.
Above-mentioned said thermosetting resin matrix material can be that a kind of or several resins in epoxy resin, unsaturated polyester resin, phenolic aldehyde, the furane resin is shared, or with the thermosetting resin of thermoplastic base resin, modified rubber.
Above-mentioned high-abrasive material can be powdery inorganic minerals such as carborundum powder, alumina powder, cast stone material; Antifriction material can be that in the inorganic antifriction materials such as stone is black, molybdenum disulphide one or more are shared.
Above-mentioned conductive material, antistatic additive can be metal powders such as silver powder, copper powder, zinc powder, iron powder, and one or more in graphite powder, carbon black and the artificial antistatic material are shared.
Above-mentioned fire proofing, fire retardant can be inorganic material such as hydrated alumina, borate, phosphate, antimony oxide; Organic fire-retardant such as chlorinated paraffin, hexabromo phenylate, triphenyl phosphoric acid fat and halogen-containing, phosphorous cmpd and artificial synthetic fire-retardant, do not fire a kind of or several the common synergistics in the resin.
Manufacture method of the present invention has two kinds: (1) adopts cold pressing forming process to see accompanying drawing 3; (2) resin transfer molding (RTM) process (RTM) is seen accompanying drawing 4.With the thermosetting resin is basis material.Its mold design all designs bright mould according to external diameter, the length dimension of sleeve; According to internal diameter, bearing (seat) hole, length dimension design core rod (formpiston); Formed space, bright formpiston assembling back is the actual materials volume of sleeve.Treat to extract core rod (formpiston) out behind the resin solidification, dismantle former and just make this superhybrid composite sleeve.
The accompanying drawing master is bright:
