Title (EN) INTERNAL-COMBUSTION ENGINE
(FR) MOTEUR À COMBUSTION INTERNE
(JA) 内燃機関
Abstract:
(EN) This internal-combustion engine is provided with: a crank case (33b); a rolling bearing (48) having an outer race (74a) which is inserted into a bearing hole (47) in the crank case (33b); a crankshaft (46) which is fitted into an inner race (74b) of the rolling bearing (48) and which is supported with freedom to rotate in the crank case (33b); a push plug (75) which is guided with freedom to be displaced along a guide path (77a) that is disposed in the crank case (33b) and extends in the axial direction of the crankshaft (46), and which is in contact with the outer race (74a) at a wedge surface (76) which moves away from the outer race (74a) with increasing distance toward a front end; and a holding member (77) which is screwed into the crank case (33) by means of a thread groove (79) coaxial with the guide path (77a) and which holds a resilient body (78) causing a driving force based on an elastic force to acts on the push plug (75) in a forward direction.
(FR) L'invention concerne un moteur à combustion interne pourvu: d'un carter de vilebrequin (33b); d'un palier à roulement (48) ayant une bague extérieure (74a) qui est insérée dans un trou de palier (47) dans le carter de vilebrequin (33b); d'un vilebrequin (46) qui est monté dans une bague intérieure (74b) du palier à roulement (48) et qui est supporté avec une liberté de rotation dans le carter de vilebrequin (33b); d'un poussoir (75) qui est guidé avec une liberté de déplacement le long d'un trajet de guidage (77a) qui est disposé dans le carter de vilebrequin (33b) et qui s'étend dans la direction axiale du vilebrequin (46), et qui est en contact avec la bague extérieure (74a) au niveau d'une surface de coin (76) qui s'éloigne de la bague extérieure (74a) avec une distance croissante vers une extrémité avant; et d'un élément de maintien (77) qui est vissé dans le carter de vilebrequin (33) au moyen d'une rainure de filetage (79) coaxiale au trajet de guidage (77a) et qui maintient un corps élastique (78) provoquant une force d'entraînement sur la base d'une force élastique agissant sur le poussoir (75) en direction avant.
(JA) 内燃機関は、クランクケース(33b)と、アウターレース(74a)でクランクケース(33b)の軸受孔(47)に挿入される転がり軸受(48)と、転がり軸受(48)のインナーレース(74b)に嵌め込まれて、クランクケース(33b)に回転自在に支持されるクランクシャフト(46)と、クランクケース(33b)に配置されてクランクシャフト(46)の軸方向に延びる案内路(77a)に変位自在に案内されて、前端にいくにつれてアウターレース(74a)から遠ざかる楔面(76)でアウターレース(74a)に接触するプッシュプラグ(75)と、クランクケース(33)に案内路(77a)に同軸のねじ溝(79)でねじ込まれ、前進方向にプッシュプラグ(75)に弾性力に基づく駆動力を作用する弾性体(78)を保持する保持部材(77)とを備える。
