Description

DESCRIZIONE dell’invenzione avente per TITOLO: “Cremagliera a segmenti modulari in materiale plastico” DESCRIPTION of the invention with TITLE: "Rack with modular segments in plastic material"

La presente invenzione riguarda una cremagliera dentata di uso meccanico, realizzata interamente in materiale polimerico, in particolare una mescola di nylon, fibra di vetro ed elastomero. The present invention relates to a toothed rack for mechanical use, made entirely of polymeric material, in particular a mixture of nylon, glass fiber and elastomer.

Attualmente le cremagliere sono realizzate completamente o in parte con materiali metallici al fine di assicurare la giusta resistenza, quando sottoposta a lavoro meccanico. Currently the racks are made entirely or in part with metallic materials in order to ensure the right resistance, when subjected to mechanical work.

L’utilizzo di materiali metallici comporta una serie di problemi legati all’ ossidabilità, la necessità di lubrificazione e l’isolamento elettrico. The use of metallic materials involves a number of problems related to oxidation, the need for lubrication and electrical insulation.

Uno dei problemi più comuni delle cremagliere dentate è la perdita dei denti, in particolare quelli che subiscono il lavoro con l’avvio del motore. One of the most common problems of toothed racks is the loss of teeth, especially those that undergo work when the engine is started.

_ Sulla necessità di ovviare a questa serie di problematiche, si è sviluppata una cremagliera interamente di materiale plastico. _ Based on the need to overcome this series of problems, a rack made entirely of plastic material has been developed.

Con la presente invenzione si è sviluppato il progetto di una cremagliera dentata di materiale composito, With the present invention, the design of a toothed rack made of composite material has been developed,

che sottoposto a particolari processi di lavorazione rende il materiale resistente ed elastico quando sottoposto a lavoro meccanico. _ which subjected to particular manufacturing processes makes the material resistant and elastic when subjected to mechanical work. _

La suddeta mescola viene utilizzata per produrre moduli stampati di cremagliera. I singoli moduli di 50 cm sono assemblati atraverso un semplice meccanismo ad incastro maschio - femmina per otenere le diverse lunghezze a seconda degli usi. The above compound is used to produce molded rack modules. The single modules of 50 cm are assembled through a simple male - female interlocking mechanism to obtain the different lengths according to the uses.

L’uso di questo prodoto trova larga applicazione negli ambienti definiti critici come quelli marini o con temperature estreme. The use of this product is widely used in environments defined as critical such as marine ones or with extreme temperatures.

I vantaggi apportati dalla realizzazione della seguente invenzione sono: La cremagliera cosi prodotta non può subire fenomeni di ossidazione; inoltre è completamente isolata dal punto di vista eletrico. The advantages brought about by the realization of the following invention are: The rack thus produced cannot undergo oxidation phenomena; moreover it is completely isolated from the electrical point of view.

Struturalmente è molto resistente ma risulta elastica e flessibile da ammortizzare il lavoro meccanico, questo si traduce in una notevole resistenza dei denti. Structurally it is very resistant but it is elastic and flexible to amortize the mechanical work, this translates into a considerable resistance of the teeth.

Non avendo parti metalliche conserva dimensioni stabili se sottoposta a drastiche variazioni di temperatura, è molto leggera e non necessita di lubrificazione. Having no metal parts, it retains stable dimensions when subjected to drastic changes in temperature, it is very light and does not require lubrication.

L’utilizzo di materiale plastico garantisce silenziosità nell’accoppiamento pignone-cremagliera. The use of plastic material guarantees silence in the rack-pinion coupling.

In particolare ogni modulo della cremagliera dentata viene prodota per stampaggio, e le singole parti del modulo, barra retangolare, denti e boccole distanziali sono concepite e prodote come corpo unico, quindi, non sono sottoposti a processi di assemblaggio. In particular, each module of the toothed rack is produced by molding, and the individual parts of the module, rectangular bar, teeth and spacer bushings are designed and produced as a single body, therefore, they are not subjected to assembly processes.

Il processo di lavorazione ato a produrre l’oggeto in questione consta di due fasi principali. The manufacturing process used to produce the object in question consists of two main phases.

La prima punta all’organizzazione strutturale interna del modulo, in particolare, sviluppa un architetura ordinata e omogenea delle fibre in tutto il volume, evitando cosi punti di fragilità. Questa è garantita dalla modalità di iniezione nello stampo, effetuata in modo da imporre direzionalità alle fibre di vetro. The first focuses on the internal structural organization of the module, in particular, develops an orderly and homogeneous architecture of the fibers throughout the volume, thus avoiding points of fragility. This is guaranteed by the injection method in the mold, carried out in such a way as to impose directionality on the glass fibers.

La seconda fase invece è finalizzata a rendere il materiale resistente e flessibile tale da sopportare il lavoro meccanico. -Come è riportato in figura 1, la strutura dei moduli è stata ulteriormente rinforzata dalle nervature riportate su entrambi i lati, che in particolar modo ammortizzano il carico in trazione e compressione. The second phase, on the other hand, is aimed at making the material resistant and flexible to withstand mechanical work. -As shown in figure 1, the structure of the modules has been further reinforced by the ribs on both sides, which in particular cushion the load in traction and compression.

In fig. 2 è messo in evidenza il meccanismo di incastro maschio- femmina utilizzato per assemblare la cremagliera. In fig. 2 highlights the male-female interlocking mechanism used to assemble the rack.
