摘要： A bearing structure of a crankshaft in an internal combustion engine supports a crankshaft on a crankcase with rolling bearings includes a play absorbing device for absorbing the play in the radial direction generated between an outer race of the rolling bearing and a bearing hole of the crankcase. The play absorbing device includes a push plug which pushes an outer race of the ball bearing in the direction perpendicular to an axis of the crankshaft. The push plug is arranged in parallel to the crankshaft between the cylinder and the crankshaft. The outer race of the ball bearing is resiliently biased toward a side of the bearing hole of the crankcase which receives an explosion pressure. As a result, the generation of a hitting sound which is attributed to the above-mentioned “play” can be largely reduced even with respect to an internal combustion engine with a high explosion pressure.

摘要： An internal combustion engine includes a split crankcase with spaced-apart journal walls. Each journal wall has a bearing hole formed therein. The engine also includes rotary bearings for supporting rotary movement of a crankshaft. A backlash-absorbing mechanism is situated proximate a first one of the rotary bearings, for cushioning radial movement of an outer bearing race. Axial movement-restraining structure is also provided adjacent the outer race, for limiting axial movement thereof. The axial movement-restraining structure may include an engaging groove provided in an inner circumferential surface of the outer race, and a restraining clamp member operatively attached to a surface of the crankcase. The restraining clamp member may include a hook portion which engages with the engaging groove of the outer race. The axial movement-restraining structure allows at least one of the crankshshaft support bearings to be a roller bearing or a needle bearing, instead of a ball bearing.

摘要： A connection structure between a plastic gear and a shaft permits easy phase matching relative to a device mounted on the shaft, and easy meshing of a gear provided on the shaft with another gear. The connection structure includes a plastic gear, a shaft, and a set plate. The plastic gear has a geometric recess which receives the correspondingly-shaped set plate therein. The set plate includes a central shaped opening. The shaft is provided with a mating extension extending from a first end, and which fits within the shaped opening. The mating extension is formed such that the plastic gear may be mounted thereon in a first position wherein the plastic gear is not positioned to interact with a mating gear, and the plastic gear can be slidably moved thereon to a second position such that the plastic gear is positioned to interact with the mating gear.

摘要： A first aspect of an oil distributing structure for an internal combustion engine includes a bearing support wall including a plurality of guide ribs which are radially mounted on a surface thereof. The guide ribs may be integrally formed, and extend around an upper half of the bearing, for collecting oil which is splashed onto, and flows down the wall surface. In a second aspect of an oil distributing structure for an internal combustion engine, a slanted edge portion, descending toward the bearing, is formed on the bearing support wall, and is disposed laterally of a lower portion of the bearing. The described structure is useful for collecting oil splashed onto a wall surface of a crankcase, and for supplying the collected oil to a bearing in an internal combustion engine of the type in which a crankshaft bearing is supplied with oil splashed from nearby gears.
