Definitions
- the invention relates to a frictional drive belt with a base body and a cover layer made of rubber or rubber-like plastic, which has a tension member layer embedded in the rubber or rubber-like plastic.
- V-belts To frictional drive belts or power transmission belts, such as. B. flat belts, V-belts, V-ribbed belts or toothed V-belts with open flanks, which are generally used where large transmission ratios have to be realized, high demands are placed on wear resistance, noise and dynamic resilience. So drive belts are used for. B. for power transmission in areas of application from office machines to the heaviest machine drives. Driving belts are also used in a wide variety of designs in motor vehicles, especially where decoupling of vibrations of the driving unit and the driving unit is important. V-ribbed belts are used, for example, in motor vehicles to drive the alternator. V-ribbed belts offer the advantage that they combine the high flexibility of the flat belt with the efficient power transmission of the V-belt and can also be used in the most complicated drive designs with counter-bending by means of deflection and back tensioning pulleys.
- the outer surfaces of the belts are subjected to a wide variety of weather and operating media influences. Despite these influences, the belts should have a long service life and, at the same time, the running noises should be reduced, particularly in the automotive and home-quality industries.
- Noises occur in drive elements in which belts provide power transmission by means of frictional engagement, often when e.g. B. in damp, cold weather in the friction behavior between the belt surface and drive pulley friction conditions occur, which cause squeaky tones by oscillation or vibration. These noises can be prevented or suppressed by various measures.
- different approaches have already been proposed in order to reduce the noise development with frictional drive belts. If you go z. B. from the manufacturing process for V-ribbed belts, in which two manufacturing processes, the grinding process and the molding process, have prevailed, it is known to reduce the noise of the belt on the
- Pulley to mix fibers into the rubber compound that forms the ribs Pulley to mix fibers into the rubber compound that forms the ribs.
- the grinding process for belts with fiber-containing mixtures is e.g. B. from the
- EP 642 886 A1 known.
- belt blanks are first produced and vulcanized, which have a smooth outer surface. Then the
- the fibers added to the mixture are preferably oriented transversely to the belt circulation direction. In the grinding process, the ribs are then ground out so that fiber tips protrude from the mixture surface.
- the ribs are then ground out so that fiber tips protrude from the mixture surface.
- polyamides such as. As nylon, or aramids can be used.
- the favorable noise behavior of such belts is often not maintained over the entire life of the belt, since the rib surfaces grind smoothly on the pulleys and then no outstanding fibers remain, which bring about the favorable friction conditions and a reduction in noise.
- Belts are therefore currently being produced in which an adhesive layer is applied to the rubber mixture plate for the ribs, to which in turn short fibers are applied in a coating process, as is disclosed, for example, in US Pat. No. 3,190,137. Due to the concentrated application in a thin layer, the fibers effectively reduce noise and at the same time in most cases they improve abrasion. Generally layers of short cotton fibers are used, which show a good compromise between cost and noise reduction. Wool is not suitable for the current thermal stresses. For synthetic fibers such as aliphatic polyester, e.g. B.
- the present invention is based on the object of providing frictional drive belts which prevent or reduce noise development in belt drives.
- This object is achieved according to the invention in that only the surface or a part of the surface of the drive belt, preferably the movement-transmitting part of the surface, is provided with a flocking material made of short aramid fibers, with a part of the aramid fibers, preferably the predominant number of aramid fibers, only with a partial length of each individual fiber is integrated into the surface.
- aramid fibers which are known to be synthetic fibers, are very good at generating noise prevent or cause a very good noise insulation. This positive behavior is apparently particularly pronounced when the aramid fibers are concentrated on the surface of the belt. Because a belt that is manufactured using the grinding process or the surface of which is ground after production using the molding process and that contains aramid fibers incorporated into the rib mixture, showed no better noise behavior than a belt with fibers made of another material. The incorporated aramid fibers only improve the abrasion behavior compared to other incorporated fibers with good abrasion-resistant fiber tips.
- the drive belts according to the invention can be, for. B. flat belts, V-belts, V-ribbed belts or toothed V-belts with open flanks, it being possible for the entire surface of the drive belt to be provided with the flocking material made of short aramid fibers.
- the positive influence of the coating with aramid fibers is particularly noticeable where the belt comes into direct contact with pulleys, rollers or wheels and where oscillation and vibration can occur.
- the belt can, for example, be provided with flocking material made of short aramid fibers on its back, since it often runs past tension or deflection films with the belt back.
- the belt on its movement-transmitting part of the surface is flocked with the aramid fibers, since different friction conditions with resulting noises (squeaking) are particularly noticeable on this part of the surface.
- Under the flocked surface there may be a rubberized reinforcement fabric (sheathing fabric), which additionally protects the belt from abrasion and already has a certain positive influence on friction behavior and noise.
- the drive belts according to the invention can be produced by ecologically and economically favorable molding processes, no material has to be ground off. Since no fibers have to be incorporated into the mixture, a higher overall flexibility of the mixture can be achieved than with mixtures containing fibers.
- the use of aramid fibers offers the advantage over the use of cotton fibers that aramid fibers do not absorb water, i.e. they do not swell. The friction behavior of a belt provided with aramid fibers is therefore much more independent of the moisture content in the environment.
- the aramid fibers advantageously have a length of 0.1 to 6 mm and a diameter of 5 to 25 ⁇ m.
- fibers are longer and thinner, processing problems arise since the fibers clump together in a cotton-like form and cannot be dosed evenly for flocking. If the length of the fibers in the case of a V-ribbed belt exceeds approximately three to four times the spacing between the ribs, this can lead to shaping problems in rib production. In addition, fiber lengths in the specified range have proven to be optimal for anchoring. Shorter fibers do not penetrate sufficiently into the adhesive layer and lie more or less like a powder on the surface to be flocked. Too long fibers penetrate enough, but due to the unfavorable ratio of the integrated to the non-integrated fiber length, they can be easily held or pinched and are easier to pull out or tear when the belt is in operation.
- the belt surface of the unvulcanized belt is prepared by swelling with a solvent or by previously applying an adhesive or an adhesive solution so that the fibers can adhere to the surface.
- the fibers are then mechanically sprinkled, blown or shaken, or with the help of an electric field or through
- aramids for the flocking fibers both copolymers of essentially terephthalic acid and p-phenylenediamine (para-aramids), e.g. B. Kevlar ® or Twaron ® , as well as copolymers of essentially m-phenylenediamine and isophthalic acid (meta-aramids), for. B. Nomex ® can be used.
- para-aramids e.g. B. Kevlar ® or Twaron ®
- metal-aramids e.g. B. Nomex ®
- other monomers can also be copolymerized into the copolymers. So can too
- Terpolymers of terephthalic acid, p-phenylenediamine and other monomers such as. B. Technora ® can be applied. Copolymers of terephthalic acid and p-phenylenediamine such as Kevlar ® or Twaron ® offer good stiffness of the fibers and thus good noise insulation. However, these materials are not as dynamic dynamically as they can break under extreme dynamic loads. Meta-aramids such as Nomex are much more durable and dynamically stable, but form less noise insulation due to their greater flexibility; they also offer the advantage of being dyeable and avoiding the rather unsightly yellow color that straps based on Kevlar ® , Twaron ® or Technora ® have. Terpolymers of terephthalic acid, p-phenylenediamine and other monomers such as Technora ® are in the two
- the drive belt or parts of the drive belt have a polymer-containing outer coating which is firmly connected and / or cross-linked by a vulcanization process with the rubber or rubber-like plastic of the base body and / or the cover layer, and a part
- the aramid fibers are only included in this coating with a partial length of each individual fiber.
- the polymer-containing outer coating acts as an adhesive for the fibers and additionally offers the advantage that, due to the intimate connection with the rubber or rubber-like plastic of the belt, it connects the fibers extremely firmly to the belt surface.
- This polymer-containing coating can be, for example, rubber solutions, urethane systems or systems based on cyanoacrylate in organic solvents.
- These polymer-containing coating solutions are those that contain suitable polymers either alone or with fillers and vulcanization systems.
- suitable polymers either alone or with fillers and vulcanization systems.
- preference is given to choosing those which give good binding to the rubber mixture to be coated.
- Adhesive systems are often added to such solutions, which also ensure the adhesion between the coating solution and the mixture underneath to the fibers.
- Adhesive systems are preferred modified phenolic resins or resorcinol resins, which contain formaldehyde donor systems such as hexamethoxymethylmelamines or urotropins as hardeners.
- Adhesive solutions for such uses are preferably provided with vulcanization systems based on sulfur or peroxide.
- Sulfur systems then contain accelerators based on sulfenamide, dithiocarbamate, guanidine or thiuram or other systems
- peroxide systems can contain salts or esters of polymerized unsaturated organic acids such as acrylic acid or methacrylic acid
- the polymer-containing coating can be such that the belt is thereby improved with regard to further relevant properties.
- the abrasion and thus the service life, the friction behavior and also the noise behavior can be additionally influenced.
- This can e.g. B. happen that the polymer-containing outer coating has fluoropolymers.
- the fluoropolymers can particularly influence the sliding behavior of surfaces and are extremely inert and non-fogging.
- polytetrafluoroethylene (PTFE) is used as the fluoropolymer.
- copolymers or terpolymers such as, for example, ethylene-tetrafluoroethylene copolymers or tetrafluoroethylene-hexafluoropropylene-vinylidene fluoride terpolymers.
- Such polymers are e.g. B. available under the trade name Dyneon THV ® from Dyneon GmbH.
- the drive belt is a V-ribbed member, the rib surface of which is provided with the flocking material made of short aramid fibers.
- the positive influence of the coating with short aramid fibers on the noise development in belt drives was particularly great
- the drive belts according to the invention can be produced by methods known to those skilled in the art.
