DESCRIZIONE DESCRIPTION
L'invenzione riguarda un corpo portante, secondo il preambolo della rivendicazione principale . The invention relates to a load-bearing body, according to the preamble of the main claim.
Dal· DE 40 15 028 è già noto un dispositivo automatico tenditore, il quale presenta un corpo portante con un manicotto cilindrico sotto forma di supporto scorrevole. Questo viene fissato ad esempio ad un blocco motore per mezzo di un perno il quale si impegna attraverso un foro passante. Sul manicotto a forma di supporto scorrevole è alloggiato un elemento orientabile il quale porta un rullo di bloccaggio in posizione eccentrica. From DE 40 15 028 an automatic tensioning device is already known, which has a supporting body with a cylindrical sleeve in the form of a sliding support. This is fixed, for example, to an engine block by means of a pin which engages through a through hole. An adjustable element is housed on the sleeve in the form of a sliding support which brings a locking roller into an eccentric position.
Il corpo portante è provvisto di una piastra di fondo che presenta dispositivi per il fissaggio della estremità di una molla. Anche se non si possono opporre critiche al funzionamento di questo noto dispositivo, sono però auspicabili interventi per semplificarne la produzione. The supporting body is provided with a bottom plate which has devices for fixing the end of a spring. Even if there is no criticism of the operation of this known device, interventions to simplify its production are however desirable.
Lo scopo della invenzione è quello di realizzate il corpo portante del dispositivo tenditore noto in modo più economico, a parità di funzionamento e di affidabilità. The object of the invention is to produce the supporting body of the known tensioning device in a more economical way, with the same operation and reliability.
Il problema viene risolto per il fatto che il corpo portante è formato in materia plastica e nella miscela del materiale vengono aggiunte particelle di scorrimento. The problem is solved by the fact that the supporting body is formed of plastic and sliding particles are added to the mixture of the material.
Grazie alla esecuzione in materia plastica, la piastra di fondo e il corpo portante possono essere prodotti in un solo pezzo e quindi in modo più economico. Con l’aggiunta alla miscela di particelle di scorrimento, la superficie cilindrica del perno si può impiegare direttamente come superficie di supporto scorrevole. Può quindi venire a mancare il manicotto scorrevole altrimenti necessario. Rispetto alla esecuzione nota, è quindi necessario soltanto un singolo componente al posto di tre. Ciò comporta anche un montaggio più economico. Thanks to the plastic design, the base plate and the carrier body can be produced in one piece and therefore more economically. With the addition of sliding particles to the mixture, the cylindrical surface of the pin can be used directly as a sliding support surface. The otherwise necessary sliding sleeve may therefore be missing. Compared to the known version, only a single component is therefore required instead of three. This also results in cheaper assembly.
Quale materiale plastico viene di preferenza impiegato il Duroplast o la poliammide. e viene aggiunta alla miscela come mezzo di scorrimento una aggiunta fino al 20% di PTFE, M0S2 oppure grafite. Duroplast or polyamide is preferably used as the plastic material. and an addition of up to 20% of PTFE, M0S2 or graphite is added to the mixture as flow medium.
Queste e altre caratteristiche verranno descritte nel seguito in base all’esempio illustrato nel disegno. La figura unica mostra la sezione longitudinale di un dispositivo tenditore per cinghie di trascinamento. Esso è formato essenzialmente da un corpo cavo 1. da un elemento orientabile 2 alloggiata su di esso, con un rullo di tensione 3 alloggiato con possibilità di rotazione per mezzo,di un cuscinetto a sfere. Tra il corpo portante 1 e l'elemento orientabile 2 viene impiegata una molla di torsione 4 " per produrre il precarico riguardo alla cinghia di trascinamento non illustrata. These and other features will be described below based on the example shown in the drawing. The single figure shows the longitudinal section of a tensioning device for driving belts. It is essentially formed by a hollow body 1 by an orientable element 2 housed thereon, with a tension roller 3 housed with the possibility of rotation by means of a ball bearing. A torsion spring 4 "is used between the supporting body 1 and the orientable element 2 to produce the preload with respect to the drive belt not shown.
Il corpo portante 1 è provvisto di un perno cilindrico 5 nel cui foro è inserito un manicotto distanziale 6. ricavato mediante l’arrotolamento di una striscia di lamiera di acciaio. Esso alloggia un perno eccentrico 7 con una flangia la quale serve per regolare il dispositivo tenditore ed è provvisto di un foro 8 per un bullone di fissaggio. The bearing body 1 is provided with a cylindrical pin 5 in whose hole a spacer sleeve 6 is inserted. Obtained by rolling up a strip of steel sheet. It houses an eccentric pin 7 with a flange which serves to adjust the tensioning device and is provided with a hole 8 for a fixing bolt.
L'intero corpo portante 1 viene prodotto in materia plastica con un procedimento di stampaggio a iniezione, da Duroplast rinforzato con fibre di vetro con una aggiunta di un 10% di materiale di scorrimento in PTFE. In questo modo, la superficie esterna del perno cilindrico può venire utilizzata direttamente come superficie 9 di un supporto di scorrimento. La superficie del foro dell’elemento orientabile 2 è adattata in corrispondente, per cui si ricava senz’altro un supporto orientabile. The entire bearing body 1 is produced in plastic material with an injection molding process, from Duroplast reinforced with glass fibers with an addition of 10% of PTFE sliding material. In this way, the outer surface of the cylindrical pin can be used directly as a surface 9 of a sliding support. The surface of the hole of the orientable element 2 is adapted in correspondence, so that an orientable support is certainly obtained.
Il corpo portante 1 è inoltre provvisto di elementi 10 ricavati di formatura per un fissaggio senza possibilità di rotazione, per l'alloggiamento della estremità 11 della molla, per il sostegno assiale 12 dell’elemento orientabile 2, per la copertura 13 del vano occupato dalla molla ecc. The bearing body 1 is also provided with forming elements 10 for fastening without the possibility of rotation, for housing the end 11 of the spring, for the axial support 12 of the orientable element 2, for the covering 13 of the compartment occupied by the spring etc.
