Title (EN) GEAR MECHANISM OF POWER TRANSMITTING SYSTEM
(FR) MECANISME D'ENGRENAGES DE SYSTEME DE TRANSMISSION DE PUISSANCE
Abstract:
(EN) The present invention provides a gear mechanism of a power transmitting system, which includes a crank gear operatively coupled with a crankshaft, and a first driven gear (31) that is coupled with a first balance shaft (30) via a damping mechanism (54) that allows relative rotation between the driven gear and the balance shaft. The damping mechanism includes a friction damper (54a, 54b) that generates frictional force when the first driven gear and a counter gear fixed to the first balance shaft rotate relative to each other within a predetermined rotational phase range or angle, and a stopper rubber or rubbers (55a, 55b) that elastically deforms to generate elastic force when the first driven gear and the first balance shaft rotate relative to each other beyond the predetermined rotational angle.
(FR) La présente invention concerne un mécanisme d'engrenages d'un système de transmission de puissance, comprenant un engrenage à vilebrequin, couplé de façon fonctionnelle à un arbre à vilebrequin, et un premier engrenage mené, couplé à un premier arbre d'équilibrage, par l'intermédiaire d'un mécanisme d'amortissement qui permet la rotation relative entre l'engrenage mené et l'arbre d'équilibrage. Ce mécanisme d'amortissement comprend un amortisseur de friction, qui produit une force de friction, lorsque le premier engrenage mené et un engrenage de renvoi, fixé au premier arbre d'équilibrage, tournent l'un par rapport à l'autre, dans un domaine ou un angle de phase de rotation prédéfini, ainsi qu'un/des bouchon(s) en caoutchouc qui se déforme(nt) élastiquement, afin de produire une force élastique, lorsque le premier engrenage mené et le premier arbre d'équilibrage tournent l'un par rapport à l'autre au-delà de l'angle de rotation prédéfini.
