[0001] " Device for equilibrating rotating masses or masses capable of rotating " DESCRIPTION

[0002] Technical field of the invention

[0003] The present invention refers to the field of technologies, methods, and devices used for equilibrating rotating masses or masses capable of rotating for obtaining the stability both of said masses when rotate about a central axis thereof, such for example, the rims of wheels, and consequently the same wheels, or generally gears rotating about their central rotation axis, and the stability of all those systems in which said masses rotating about their respective central axis, operate: generally vehicles or all those mechanical systems characterized by the presence, due to their operation, of masses rotating about their own central rotation axis.

[0004] Background of the invention and problem to be solved

[0005] In field of the general mechanics, for the purpose of equilibrating rotating masses or masses capable of rotating about their respective central rotation axis, for a long time particular attention has been given to the equilibration of rims of wheels, and therefore of the same wheels, by using initially approximated methodologies, which over the years were refined even though they are still affected by huge problems: both direct problems with reference to the health of the operators of this field and with reference to the processing times, and indirect problems with reference to the disposal and eco-compatibility of the residues and of the processing scraps.

[0006] Particularly, for the purpose of equilibrating the wheel rims, and therefore the wheels themselves, an operator loads the wheel rim on a suitable balancing machine which, by setting it into rotation, about the rim central axis, the whole wheel, shows the operator at the rim edge, in proximity to the tire, or in other points of the perimetral zone of the rim, where already calibrated counterweights having known weights should be positioned.

[0007] Despite the help given to an operator by the balancing machine, there is still a multiplicity of unresolved problems.

[0008] In case of the procedure of equilibrating wheels provided with steel rims, the used counterweights, which also made of steel, are mainly counterweights having a spring calibrated value, to be used both for the static and the dynamic equilibrations, to be positioned only in proximity to the rim edge which laps the tire. When the balancing machine, by a light pointer, shows to position one or more counterweights at points where it is not possible to fasten the former by spring, it is imperative the use of counterweights applicable by an adhesive layer present on the counterweights themselves. This solution is the only one available for rims made of an alloy.

[0009] During the equilibrating procedure, an operator must accurately clean the rim, both the one made of steel and more importantly the one made of alloy, in order to start from a condition suitable for correctly equilibrating the wheel.

[0010] This necessarily implies that, before loading the wheel and its rim on the balancing machine, the rim must be accurately cleaned by using brushes, solvents, and that the already present counterweights mounted by adhesive or spring must be removed, consequently the processing times are lengthened, generating in turn substantial amounts of processing residuals and scrap materials: all the counterweights applied or applicable by adhesive, once removed, are unusable and consequently they are discarded because they cannot be easily recycled or reused. Moreover, the operators of the field are forced to work under conditions of risk for their health because they are required to wear masks for preventing them from inhaling the processing residuals, such as fine dust generated by the use of rotating brushes for removing the adhesive released by a counterweight from the rim, and the solvents used for removing all the impurities present on the rim, in order to enable to adhere new counterweights.

[0011] Therefore, it was strongly felt in the specific field of wheels for vehicles, for the purpose of an optimization of the equilibrating process, to develop new technical solutions capable of overcoming the inconveniences typical of the present equilibrating procedures, which are also as good and effective as the present ones.

[0012] Therefore, the Applicant has noted that there is the possibility to realize, for the purpose of equilibrating the wheels of a vehicle and more, one or more devices, respective accessories / kits, and their uses, that represent a technical solution capable of reducing the processing times, of improving the work conditions of the operators of this field, of reducing or even eliminating the actually present wastes and sources of pollution.

[0013] Objects of the invention

[0014] Therefore, the main object of the present invention consists of overcoming the beforehand described inconveniences of the prior art.

[0015] The Applicant, operating in the technical field of equilibrating vehicle wheels, has developed and realized a substantially effective technical solution which is an alternative to the ones of the prior art. An object of the present invention consists of providing a methodology, and therefore a device, an assembly, or kit, capable of enabling to equilibrate vehicle wheels and more, wherein it is obtained: a reduction of the processing times, by making useless processing steps which are now considered necessary, better conditions of work for the operators of the field by avoiding the use of solvents and the generation of fine dust which are noxious to the airways; a reduction or even an elimination of waste materials: consequently it is obtained a complete reuse in real time of the material to be employed for the equilibration procedure.
