Abstract
The utility model discloses a double-layer reinforced carrier roller body for a conveyer. The double-layer reinforced carrier roller body comprises an outer-layer roller body, wherein an inner-layer roller body is further arranged in the outer-layer roller body, and the inner-layer roller body is connected with the outer-layer roller body via a plurality of reinforcing ribs; and bearing positions used for accommodating bearings are further arranged at the both ends of the inner-layer roller body. By adopting the structure and shape aforementioned, and combining with materials in the prior art, the double-layer reinforced carrier roller body disclosed by the utility model has the beneficial effects of being high in dimensional accuracy, good in bending strength, simple in production process, smooth in surface, low in friction coefficient, capable of protecting a belt, anti-corrosive, rustproof, long in service life, maintenance-free, good in water resistance, and capable of being used in damp conditions or outdoors for a long time; and bearing seats are cancelled, thus further simplifying the production process.
Description
Technical field
The utility model relates to a kind of conveyer carrying roller, particularly a kind of double-deck reinforcement conveyer carrying roller cylindrical shell, especially a kind of polypropylene, polyethylene or ultra high molecular polyethylene carrying roller that is used for substituting the steel carrying roller.
Background technology
Traditional conveyer carrying roller tube adopts steel pipe and polyethylene pipe to make usually, and the shortcoming of existing steel idler pulley tube and polyethylene pipe is as follows:
1, energy consumption is big in process of production, operation is many, the cycle is long for the conventional steel roller supporting tube, most critical be not withstanding corrosion of cylindrical shell, can't guarantee ordinary production for chemical enterprises and colliery.
2, as shown in Figure 3, though but the idler structure withstanding corrosion flexural strength that polyethylene pipe is made is not enough, the roller supporting tube of making of polyethylene pipe will be placed in bucket and strengthen upholder, for example band iron support, and production process is loaded down with trivial details and can not fundamentally solve the counter-bending problem of roller supporting tube.So just, caused the service life of carrying roller short, the maintenance cost height of enterprise's facility.
3, existing roller and bearing seat are independent element, and procedure of processing is many, and trouble is installed.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of double-deck reinforcement conveyer carrying roller cylindrical shell, can prolong the service life of carrying roller, and load-bearing flexural strength height, and the built-in bearing position, and it is comparatively convenient to install; Further, the material of employing can be according to adopt corresponding size production with demand.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of double-deck reinforcement conveyer carrying roller cylindrical shell, comprise outer outer layer barrel, in outer layer barrel, also be provided with internal layer cylinder, be connected by many reinforced ribs between internal layer cylinder and the outer layer barrel.
Described internal layer cylinder two ends also are provided with the bearing position that is used to hold bearing.
Described reinforced rib is the 4-8 root, is uniformly distributed along the circumference.
Described outer layer barrel, internal layer cylinder and reinforced rib adopt PP, PE or UHMWPE material.
PP is a polypropylene, and PE is a polyethylene, and UHMWPE (ultra-high molecular weight polyethylene) is a ultra high molecular polyethylene, and mol wt reaches more than 1,000,000, reaches the polyethylene kind more than 1,500,000 usually.Have good Dent resistance and self lubricity.
A kind of double-deck reinforcement conveyer carrying roller cylindrical shell that the utility model provides by adopting above-mentioned structure and shape, and combines with material of the prior art, has following beneficial effect:
1, the combination of shape of the present utility model and material is convenient to adopt extrusion moulding of extruding machine, dimensional accuracy height.
2, the combination flexural strength of shape of the present utility model and material is good, manufacture craft is simple and direct.
3, the smooth friction coefficient of material surface of the utility model selection is little, as the conveyer carrying roller cylindrical shell, helps protecting belt, has prolonged the service life of balata belt.
4, the material selected of the utility model has corrosion prevention, non-corrosive, long service life, advantage such as non-maintaining.
5, the material water-tolerant of the utility model selection can be for a long time in moist or outdoor use.
6, the bearing position by being provided with in post-production, substituted bearing seat, further simplified manufacture craft, also be convenient to the installation in later stage, and because carrying roller cylinder of the present utility model prolongs service life, reduced and changed the probability of bearing seat, thereby also prolonged the non-failure operation time of integral device.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples:
Fig. 1 is a cross sectional representation of the present utility model.
Fig. 2 looks scheme drawing for master of the present utility model.
Fig. 3 is the lateral plan of prior art middle cylinder body installation shaft bearing.
Among the figure: outer layer barrel 1, reinforced rib 2, internal layer cylinder 3, bolster 4, bearing 5, bearing position 6.
The specific embodiment
In Fig. 1,2, a kind of double-deck reinforcement conveyer carrying roller cylindrical shell comprises outer outer layer barrel 1, also is provided with internal layer cylinder 3 in outer layer barrel 1, is connected by many reinforced ribs 2 between internal layer cylinder 3 and the outer layer barrel 3.Optimize, described reinforced rib 2 is the 4-8 root, is uniformly distributed along the circumference, and adopts 4 reinforced ribs in this example.Adopt the structure of double-layer barrel, strengthened the flexural strength of cylindrical shell, cancelled the reinforced structure in the cylindrical shell, for example band iron supports, because can lower wall thickness accordingly, therefore the material of required increase is few.
Described internal layer cylinder 3 two ends also are provided with the bearing position 6 that is used to hold bearing 5.Structure has been omitted bearing seat thus, has simplified manufacture craft, has reduced tooling cost, also is convenient to the installation in later stage.
Described outer layer barrel 1, internal layer cylinder 3 and reinforced rib 2 adopt PE or UHMWPE material.Material is selected thus, especially adopts the UHMWPE material, and the utility model friction coefficient is little, has prolonged the service life of belt, and whole withstanding corrosion, water-tolerant, and impact resistance is strong.
