Abstract
The utility model relates to a drive belt utilized in belt wheel drive, particularly an elastic drive belt. The elastic drive belt of the utility model, wherein the underlayer of the cross-section is a rubber drive layer, is characterized in that a thermoplastic elastomer layer is adhered on the rubber drive layer. The utility model has the beneficial effects of high elasticity, high tenacity, convenient installation and disassembly, uniform power transmission, small noise and long life, and the utility model can do two-way transmission, and can be applied widely to the power transmission and light-duty materials transportation of textile machinery, print machinery, packing machinery and the like, particularly all kinds of mechanical power transmission and materials transportation without distance adjusting device.
Description
(1) technical field under
The utility model relates to the driving belt that uses in the belt wheel transmission, particularly a kind of elastic driving band.
(2) background technique
At present, its skeleton of the driving belt that uses in industrial production is nylon base or canvas of chemical fibre, though higher strength is arranged, elasticity is relatively poor, pulls elongation percentage less than 30%, and the machine of going up can't stretch; Though and the elongation at break of General Purpose Rubber can reach more than 350%, tensile strength only is about 15MPa, can't satisfy the requirement of transferring power behind the last machine.
(3) summary of the invention
The utility model is in order to remedy the deficiencies in the prior art, provide a kind of high elasticity, high strength, easy installation and removal, transferring power evenly, the elastic driving band of long service life.
The utility model is achieved by the following technical solution:
Elastic driving band of the present utility model comprises that rubber drives layer, and its special way is: also comprise being bonded in the thermoplastic elastomer that rubber drives layer top.
Elastic driving band of the present utility model also comprises the rubber cover that is bonded in the thermoplastic elastomer top.
Elastic driving band of the present utility model, the binding between thermoplastic elastomer and the remainder layer are hot melt film.
The beneficial effects of the utility model are, high elasticity, high strength, easy installation and removal, transferring power evenly, can two-way transmission, little, the long service life of noise, the power transmission and the light-duty mass transport that can be widely used in textile manufacturing machine, printing machinery, package packing machine etc. are specially adapted to not have all kinds of machine power transmissions and the mass transport of roll-setting gear.
(4) description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Accompanying drawing is the structural representation of the utility model cross section.
Among the figure, 1 rubber cover, 2 thermoplastic elastomers, 3 rubber drive layer.
(5) embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.
Elastic driving band of the present utility model; its cross section lower floor is that rubber drives layer 3; rubber drives layer top and is bonded with thermoplastic elastomer 2, and the top of thermoplastic elastomer is bonded with rubber cover 1, and the binding between thermoplastic elastomer and the remainder layer is a hot melt film.
Elastic driving band of the present utility model, thermoplastic elastomer 2 have high elasticity, high strength as skeleton, and transferring power is even, and is easy for installation.Extraordinary thermoplastic elastomer (TPE) is a linear structure, molecular chain is longer relatively, soft segment links to each other by chemical covalent bond tail-tail with rigid chain segment, its special high polarity makes intermolecular interaction form crystalline region, and its outstanding feature is at room temperature to have the good high elasticity of rubber, and the processing of plastic flowability is at high temperature arranged, can carry out extrusion molding, injection moulding, blowing and thermal weld processing as plastics, simultaneously pollution-free, no waste material is a kind of environment-friendly materials.And extraordinary thermoplastic elastomer (TPE) has higher tensile strength than General Purpose Rubber, brute force after it is pulled apart can reach more than the 25MPa, be more than 1.6 times of General Purpose Rubber 15MPa, elongation at break still can reach greater than 350%, therefore can be used as the framework material of elastic driving band, satisfy the stretch needs of the machine of going up of whole band, and even transferring power.
Elastic driving band of the present utility model, last coverage rate is a rubber cover 1, is that one deck is wear-resisting, the high polymer material of oil resistant.
Elastic driving band of the present utility model, adopt special hot melt film to be as the reason of bonding layer, rubber drives layer 3 material of main part and adopts specific rubber, and there is not good interior poly-Adhesion force between thermoplastic elastomer 2 skeletons, if brushing adhesive specially, technology is bad first carries out the harmful gas of the environment that second will exert an influence.The main body composition of hot melt film is the extraordinary thermoplastic elastomer (TPE) identical with framework material, is mixed with a spot of driving layer main body material simultaneously, and adhesive-bonded form is a chemical adhesive, make bonding strength by original driving belt 〉=1.5N/mm brings up to 〉=2.5N/mm.
Rubber drives that layer is wear-resisting for one deck, oil resistant, the high polymer material of fine antistatic behaviour is arranged, and surface be coarse cloth line or smooth surface, and its material of main part adopts specific rubber, and reinforcement system adopts also usefulness of nano-powder conductive black and nano-calcium carbonate; Protection system adopts ketoamine class, p-phenylenediamine (PPD) class, phenols and physics class and uses.Can play " synergistic effect " like this, the wearing valve that makes driving belt is reduced to≤120mg by≤200mg, and wear resistance improves more than 40%, dynamically antistaticly is reduced to≤120V/cm static static value≤10 by former≤200V/cm
8Ω has satisfied the specific (special) requirements of spinnery to static.Driving layer material also can be NBR, PU, PVC, Si etc.
Claims (3)
1. an elastic driving band comprises that rubber drives layer (3), is characterized in that: also comprise being bonded in the thermoplastic elastomer (2) that rubber drives layer top.
2. elastic driving band according to claim 1 is characterized in that: also comprise the rubber cover (1) that is bonded in thermoplastic elastomer (2) top.
3. elastic driving band according to claim 2 is characterized in that: the binding between thermoplastic elastomer (2) and the remainder layer is a hot melt film.
