Book excerpt: Il presente volume è frutto di un ampliamento degli argomenti trattati nella prima edizione. In questa sede sono stati aggiunti tre nuovi temi: la stozzatura, il taglio delle ruote dentate ed il controllo numerico. L’introduzione della stozzatura permette di ampliare le operazioni di taglio con moto alternato rettilineo intermittente, consentendo di mettere in luce le modalità di asportazione di truciolo necessarie alla realizzazione di scanalature, cave, e forme poligonali già viste nella brocciatura, ma estese al caso di fori ciechi o di presenza di spallamenti. La fabbricazione di ruote dentate è descritto dapprima riportando le diverse tecnologie, i relativi utensili e le macchine oggi a disposizione per la fabbricazione di ingranaggi. Successivamente le differenti soluzioni vengono confrontate in maniera critica, analizzandone i pro ed i contro, sia sotto il punto di vista della sgrossatura che della finitura. Infine le differenti combinazioni vengono analizzate anche in funzione delle tipologie di acciai utilizzati per la fabbricazione degli ingranaggi e dei trattamenti termici finali che gli ingranaggi prodotti devono subire. L’ultimo argomento aggiunto affronta il tema del controllo numerico, che è di estrema importanza nella formazione dei giovani ingegneri meccanici che entreranno nel mondo di lavoro. Quest’ultimo viene affrontato dapprima analizzando le soluzioni meccaniche che tale tecnologia introduce nelle architetture delle macchine utensili a controllo numerico; successivamente ne vengono spiegate la logica di funzionamento e le possibilità di controllo e correzione delle traiettorie ottenibili dai sistemi ad assi controllati. Infine viene affrontato il passaggio fondamentale tra il comando di una traiettoria e le prestazioni ottenibili dall’asse in relazione alla sua massa e rigidezza. Non da ultimo gli autori sono lieti di ringraziare Samputensili, un’azienda leader nella fabbricazione di centri di lavoro per la rettificatura di ruote dentate, e l’Ing. Giacomo Guerrini per il prezioso contributo nella stesura della parte del taglio degli ingranaggi.

Book excerpt: The book explores the geometric and kinematic design of the various types of gears most commonly used in practical applications, also considering the problems concerning their cutting processes. The cylindrical spur and helical gears are first considered, determining their main geometric quantities in the light of interference and undercut problems, as well as the related kinematic parameters. Particular attention is paid to the profile shift of these types of gears either generated by rack-type cutter or by pinion-rack cutter. Among other things, profile-shifted toothing allows to obtain teeth shapes capable of greater strength and more balanced specific sliding, as well as to reduce the number of teeth below the minimum one to avoid the operating interference or undercut. These very important aspects of geometric-kinematic design of cylindrical spur and helical gears are then generalized and extended to the other examined types of gears most commonly used in practical applications, such as: straight bevel gears; crossed helical gears; worm gears; spiral bevel and hypoid gears. Finally, ordinary gear trains, planetary gear trains and face gear drives are discussed. Includes fully-developed exercises to draw the reader's attention to the problems that are of interest to the designer, as well as to clarify the calculation procedure Topics are addressed from a theoretical standpoint, but in such a way as not to lose sight of the physical phenomena that characterize the various types of gears which are examined The analytical and numerical solutions are formulated so as to be of interest not only to academics, but also to designers who deal with actual engineering problems concerning the gears
