Abstract
The utility model discloses a flexible bearing roller who uses on belt conveyor. Flexible bearing roller comprises cylindrical hollow tube body, antifriction bearing and dabber, and the barrel is hollow compound packing element, and antifriction bearing and minor axis are equipped with to compound packing element both ends. The utility model discloses the operation angle is the change according to material weight on the belt on the belt feeder, and produces that different flexural bucklings change, but the automatically regulated amount of deflection, specially adapted discharge opening below and big impact load section. The utility model discloses a high abrasion, by force corrosion -resistant, low temperature resistant (46-52 degrees) combined material make, life is 2-2.5 times higher than current bearing roller, reduces the power consumption of motor. The utility model discloses a seamless steel pipe, steel axle, antifriction bearing and attached fitting can be saved in a large number in the use, and same a set of bearing roller matched stack spare expense can be saved more than 12.
Description
One, technical field
The utility model relates to the carrying roller that a kind of belt transporter uses.
Two, background technology
The formations such as the in-built steel axle of the cylindrical shell that the carrying roller that present belt feeder uses is solid drawn pipe, antifriction-bearing box, bearing chamber, door and seal ring.Its weak point: a large amount of solid drawn pipe, rod iron material and antifriction-bearing box, sealing member 1, need be consumed, and the inclination angle on belt be fixing 25 degree ~ 35 degree non-adjustable, the belt (especially steel rope core belt) throughout the year run on steel carrying roller easily produces longitudinal jackknifing along belt working direction, seriously reduces the service life of belt.2, noise is large, is up to 80 decibels, very large on working environment impact.3, solid drawn pipe, antifriction-bearing box, sealing part abrasion serious, within 1 year, a whole set of idler assembly must be changed, fittings cost is high.
Three, summary of the invention
The purpose of this utility model is to provide a kind of flexible idler; it can produce flexural buckling change in various degree according to the change of weight of material on belt; can restore to the original state rapidly during load removal, thus himself and belt are protected, and save great deal of steel and accessory.
The technical solution adopted in the utility model is: flexible idler is made up of cylinder type hollow cylindrical shell, antifriction-bearing box and mandrel, and its cylindrical shell is Hollow Compound packing element, and antifriction-bearing box and minor axis are equipped with in compound packing element two ends.The angle of flexible idler on belt transporter is change according to weight of material on belt and produces different flexural buckling changes.When belt transporter being loaded with material, transversal surface sees that belt is cabochon shape, when material on belt can regulate amount of deflection automatically by during feeding end discharging, be specially adapted to below discharge port and heavy shock loads section, the utility model adopts high abrasion, strong corrosion resistant, the composite material at temperature of the long-term resistance to end (-48 ~ 52 degree) to make.Service life improves 2 ~ 2.5 times than existing carrying roller.Reduce motor power (output) consumption.Use of the present utility model can save a large amount of solid drawn pipe, rod iron material, antifriction-bearing box and accessory, and same group of idler machining (contrasting used 31 groups or 5-linked one group of steel carrying roller) fittings cost can save more than 1/2nd.
Four, accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the making schematic diagram of the utility model combined barrel.
Five, detailed description of the invention
Flexible idler is made up of cylinder type hollow cylindrical shell, antifriction-bearing box and mandrel, and its cylindrical shell is Hollow Compound packing element 11, and antifriction-bearing box 5 and minor axis 1 are equipped with in compound packing element 11 two ends.Compound packing element 11 hollow in have coil spring 6, coil spring 6 supports on compound packing element 11 inwall, and helical spring pitch is 100 ~ 120mm.The flow ring 10 of multiple even projection is had at compound packing element 11 outside face.Bearing chamber 9 is had at compound packing element 11 two ends, antifriction-bearing box 5 is housed in bearing chamber, locating bush 4 is had in antifriction-bearing box 5 periphery, inside antifriction-bearing box 5, there is bearing inner shield ring 12, there is bearing door 3 in outside, outer gland sealing ring cowling 7 is had outside bearing door 3, outer gland sealing ring cowling 7 is fixed by holding screw 8, outside flexible back-up ring 2 outside sealing ring cap 7.The making of the utility model compound packing element 11: first the multiple flow rings 10 made in advance are placed in the groove of the steel mold 19 made, left inside mould steel cylinder 15 and right inside mould steel cylinder 16 are enclosed within a long tightening screw rod 24 from two ends, left and right, then interior catch 14 is respectively charged at long tightening screw rod 24 two ends, location cone 20, pressure pad 21, terminal block dish 22 and long bolt plain cushion 13, then respectively nut 23 is fixed on the two ends screw thread of long tightening screw rod 24, again this assembly is loaded location between mould bottom plate 17 and mould mounting plate 18, finally cast glue sulfuration.Take out after cooling, after unloading the nut 23 on long bolt 24, plain cushion 13, terminal block dish 22, pressure pad 21, location taper shank 2; Namely the cylinder assembly of flexible idler is become.In the cone 20 of cylinder assembly location, running in bearings room 9 parts such as grade make flexible idler.
The assembling of flexible idler: first bearing inner shield ring 12 is loaded bearing chamber 9, antifriction-bearing box 5(is added moderate lubrication fat) load in bearing chamber 9, bearing door 3 is installed on minor axis 1, first-class for outer gland sealing ring cowling 7, circlip 2 is brought, again fastening for the holding screw 8 at two ends good, circlip 2 is installed in the groove on minor axis 1, completes the assembling of bearing chamber parts.The locating bush 4 of the bearing chamber parts assembled with the overall compound packing element 11 vulcanizated is installed, and then bearing chamber 9 and locating bush 4 are loaded locates cone 20; Impose uniform spot welding by bearing chamber 9, locating bush 4 with locate cone 20 solder together in locating bush 4 and the outer perimeter of location cone 20 behind location, the left and right assembling of cylindrical shell is identical.Require that minor axis concentric, whole roller turn in two ends is flexibly without jam phenomenon.
