FIELD: mechanical engineering. ^ SUBSTANCE: crankcase comprises three crankcase joints. The flange of the first crankcase joint is curved and provided with base bearing surface for bearing units of the driven pinion from the side of the plane cooperating with the crankshaft. The pinions have the second joint plane that is parallel to the first one. From the opposite side, the curved flange is closed and provided with ring port for receiving the driving pinion with bearing units containing the third joint plane. The ring port is overlapped by means of the segment projection provided on the base bearing surface of the bearing unit of the driven pinion. Each joint plane is provided with mutually perpendicular ports for cooperation with the fastening and setting members. The inner surface of the crankcase is provided with means for catching, storing, and supplying oil to the friction surfaces of the bearing units of the driving pinion. The means is made of a rectangular space with rounded corners, and its smaller side is arranged along the width of the crankcase. ^ EFFECT: reduced sizes. ^ 5 dwg |
