The utility model has the advantages of oil storage and lubrication, light weight, small running resistance, good tightness, long service life, small maintenance workload, etc. The utility model has an interchanging ability with TD62 type and TD75 type supporting rollers which are generally used at home, and the utility model is suitable for all belt conveyers.
Description
The utility model relates to the basic components of belt conveyer in the Transport Machinery (belt transporter), a kind of compound type heavy wool chamber sealed plastic flute profile carrying roller of more specifically saying so.
Belt conveyer (belt transporter) is the widely used important transportation equipment of department such as modern metallurgy, coal, mine, electric power, chemical industry, building, communications and transportation.Carrying roller is that basic components, the consumption of belt transporter is very big, consumption rate is more.According to the statistics made by the departments concerned, about 5,000,000 of the carrying roller that China consumed in a year is worth more than 300,000,000 yuan, and wherein 2/3rds is flute profile carrying roller (upper supporting roller).
Before the utility model, the belt transporter carrying roller that generally uses all is a steel tubular type carrying roller both at home and abroad.The external representative carrying roller of introducing in " state foreign minister distance belt conveyor " book of publishing as coal industry press: but West Germany be with 6204,6305 profile shafts to hold and oiling labyrinth sealed flute profile carrying roller, the CLH type of Japanese transport machine company, VCH and CMF type carrying roller.Their body of roll generally adopts welded steel pipe, bearing seat by steel plate punch forming hot repressing in the body of roll, adopt labyrinth seal and oil injecting lubricating.Mostly domestic carrying roller that generally uses such as nineteen eighty-three Chemical Industry Press " the Transport Machinery handbook " published is to make the body of roll with the solid drawn pipe car if being introduced, bearing seat has steel plate punching press or castiron, and employing bearing cap shim, seal ring seal or form labyrinth seal with interior exterior seal ring.Representative product is TD62 type and TD75 type.This book also recommends to adopt full reinforced plastics pipe to make the body of roll.But, can't promote the use of because it is not shock-resistant, cost is high again.
The common problem that exists of steel tubular type carrying roller be carrying roller from great, running resistance is big, maintenance workload is big, service life is short, for addressing the above problem, as having introduced " the SL plastic dicycly return idler " of Wuhan Iron and Steel Plant invention in 1985 the 1st phases national science technical study " achievement communique ", reformed steel tubular type snub pulley, but the problem that steel tubular type upper supporting roller (flute profile carrying roller) exists is still unresolved.
The purpose of this utility model be a kind of novel flute profile carrying roller of design overcome that the steel tubular type flute profile carrying roller that generally uses at present both at home and abroad exists from problem great, that running resistance is big, maintenance workload is big, service life is short.
The utility model all improves on material and structure in order to achieve the above object, has designed compound type heavy wool chamber sealed plastic flute profile carrying roller.Promptly by roller carrier shaft 1., roller 2., bearing seat 3., little cover 4., spacing back-up ring 5., seal end plate 6., oil-sealing sleeve 7., jump ring 8., bearing 9., bolt 10., nut (11) and oil cabinet (12) combination and forming has the plastics flute profile carrying roller that the sealing of heavy wool chamber and oil storage are lubricated.As shown in Figure 1, feature of the present utility model is to be cooperated by the bearing seat of the roller of two ends inner wall belt keyway and band key and spacing back-up ring button groove to constitute the carrying roller housing; Cooperate with bearing seat by the little cover that pushes up the roller carrier shaft shaft shoulder and to constitute interior oil cabinet; Cooperate with bearing seat by seal end plate and to constitute outer oil cabinet; The inwall flush fit of the outer ring of bearing and bearing seat, both sides are inside and outside oil cabinet.
Carrying roller of the present utility model is because the combination of above-mentioned member, formed with labyrinth seal, oil injecting lubricating structure different distinctive heavy wool formula structure, make bearing obtain the sealing of three levels, ground floor is the mechanical seal that is made of seal end plate and oil-sealing sleeve, the second layer is the oil packing that is formed by the grease that stores, and the 3rd layer is by the sealing of grease to the slit.Be that the grease of oil cabinet comes up from the slit and is mixed into grease with koniology and forms sealing to the slit.The three-layer sealed the utility model that makes is better than simple mechanical labyrinth seal performance, and good sealing property is one of reason that improves this carrying roller service life.The structure of this heavy wool formula makes making, matching requirements and cost all low than labyrinth type.

Example two: carrying roller of the present utility model has plurality of specifications.Carrying roller installation dimension such as following table according to the tape width design-calculated all size of belt transporter:
| Bandwidth | Axial length L1 | The long L of roller | The roller outer diameter D | Homalocephalus h | Axle system |
| 500 | 210 | 170 | 90 | 14 | 204 |
| 650 | 270 | 210 | 90 | 14 | 204 |
| 800 | 330 | 270 | 110 | 14 | 305 |
| 1000 | 410 | 330 | 110 | 14 | 305 |
| 1200 | 490 | 400 | 130 | 18 | 306 |
| 1400 | 560 | 470 | 130 | 18 | 306 |
The carrying roller oad of all size of the present utility model is that installation dimension and homemade TD75 type and TD62 type carrying roller have interchangeability in the use, is convenient to like this promote the use of rapidly at home.
Example three: the carrying roller weight of each specification of the utility model and the contrast of TD75 type flute profile carrying roller see the following form:
| Bandwidth | TD75 type (kg/) | The utility model (kg/) | ||
| Full weight | Rotating part weight | Full weight | Rotating part weight | |
| B=500 | 5.6 | 5 | 1.41 | 0.814 |
| B=650 | 6.6 | 5.8 | 1.72 | 0.924 |
| B=800 | 8 | 6.4 | 3.54 | 1.93 |
| B=1000 | 13.6 | 11.6 | 4.18 | 2.18 |
| B=1200 | 17 | 13.9 | 6.06 | 2.96 |
| B=1400 | 20.3 | 16.8 | 6.8 | 3.3 |
Domestic TD62 and external steel carrying roller are all heavy than TD75 type carrying roller, so need not to list one by one comparison.
Carrying roller deadweight of the present utility model is little, running resistance is little, energy-saving effect is obvious. Be steel owing to the carrying roller rotating part only has bearing and bolt nut on the one hand, all the other are the engineering plastic materials and parts, so the weight of its rotating part only is 1/3～1/5 of steel tubular type carrying roller weight. Its formula W=ω (q of carrying roller running resistance1＋q
2＋q
3）L
TIn the formula: W is that running resistance, ω are resistance coefficient, q1Rotating part weight, q for carrying roller2For cargo is heavy, q3For adhesive tape is heavy, LTUnit length for belt. Can find out q by formula1And the proportional relation between the W, namely more little its running resistance of the weight of carrying roller rotating part is also just more little, and running resistance is littler, and superiority energy-conservation in long-distance transportation is just very outstanding. MC nylon has self lubricity, coefficient of friction is littler than steel because the carrying roller roller adopts on the other hand, and resistance coefficients is also little, and also can save a large amount of adhesive tapes every year.
Carrying roller of the present utility model is convenient to carrying and installation because deadweight is little, alleviates aborning labor strength, improves workman's working condition. Steel tubular type carrying roller weight is big, and special bandwidth is safeguarded carrying and installation and brought difficulty also easily to go out security incident at the heavy 17-30kg of each trough idler of the big belt feeder more than 1.2 meters, and especially high-altitude climbing belt feeder more very.
Trough idler of the present utility model is adapted at using on the standby class belt conveyers of departments' use such as metallurgy, coal, mine, electric power, chemical industry, building and communications and transportation, can obtain higher economic benefit.
