Description
Technical field
The present invention relates to a kind of manufacturing technology and hermetically-sealed construction of rotating mechanism, particularly a kind of axial laminated contact/noncontact combined sealing tape type conveyer plastic carrier roller.
Technical background
The harsh environment that carrying roller is widely used in the open, dust is large, corrosive property is strong, such as chemical industry, metallurgy industry, cement industry, mining industry, coking industry, harbour handling industry etc., and its roll body of existing carrier roller of belt conveyer is generally metal or plastic tube body, and two ends prevent the erosion of the objectionable impuritiess such as booty, dust, water by maze-type structure.But which kind of maze-type structure all can not effectively stop slag, dust and muddy water etc. to enter carrying roller inside, thereby affect the normal operation of carrying roller, cause carrying roller early failure (life-span of carrying roller only has 2 ~ 30,000 hours) and bring a series of baneful influences such as driving power rises, the adhesive tape wearing and tearing increase the weight of, must overhaul continually for this reason, change the inefficacy carrying roller, both cause the great wasting of resources, also reduced the on-road efficiency of belt conveyer.
Traditional labyrinth-type excluder, be the sealing effectiveness that improves, common measure is to dwindle the labyrinth sealed seal clearance as far as possible and prolong sealed pathway, and the dense pack grease is to realize effective sealing, yet this measure must increase the rotational resistance of carrying roller, and brings the drawback that driving power rises, energy consumption increases of belt conveyer.
The plastic conveyer roller that tradition adopts the plastic pipe of extrusion molding to make, for concentricity and the carrying roller cylindrical run-out error that guarantees the rear bearings at both ends of carrying roller assembling satisfies code requirement, all need to form stepped hole by machine up at the carrying roller two ends, and form by interference fit.Although this method can meet the demands to a certain extent by specialized equipment and frock, production process increases, and the problem that the risk of productive costs rising and qualitative control increases need to overcome.
Although injection molding plastic tube body can satisfy the requirement of bearings at both ends concentricity and cylindrical radial runout, but production efficiency is starkly lower than extrusion molding, and the injection moulding body is subject to the impact of the factors such as forming process, ambient temperature, rate of cooling, workman's technical merit, yielding behind the mould, its unrelieved stress also will have a negative impact in the whole use procedure of product.
