20090008190 | Lubrication Structure of Cranking Rotational Force Transmission Mechanism for Internal Combustion Engine - The lubricant-return holes ( | 01-08-2009 |
20090165593 | Starter for Internal Combustion Engine - A starter for an internal combustion engine includes a power transmission mechanism. The power transmission mechanism has an outer race plate fastened to a crankshaft, and a ring gear coupled to a rotational shaft of an electric motor for starting the engine. The power transmission mechanism further has a one-way clutch for permitting torque transmission only from the ring gear to the outer race plate, and two sealing members. Lubricant is supplied from the cylinder block to the interior of the power transmission mechanism for lubricating the power transmission mechanism. The outer race plate has a groove on its contact surface of a contact portion between the crankshaft and the outer race plate. The groove extends in the entire circumferential direction of the crankshaft. This maintains the coupling strength between the outer race plate and the crankshaft, while enhancing the sealing performance of the power transmission mechanism. | 07-02-2009 |
20090288295 | Ring Gear, Internal Combustion Engine-Starting Torque-Transmission Mechanism, and Method of Manufacturing Ring Gear - A ring gear is formed by joining a race side-region formed body, a gear side-region formed body and an intermediate region formed body. Accordingly, it is possible to perform processing of an inner race portion of the race side-region formed body with none of the gear side-region formed body and the intermediate region formed body present. By causing the gear side-region formed body and the intermediate region formed body to absorb changes in design depending on the type of internal combustion engine, it is possible to standardize the size and the shape of the race side-region formed body for various engine types. Because the inner race portion, as well as a disposition surface and a contact surface for the seal rings are formed on the same race side-region formed body, it is possible to finish the surfaces with precise positional relationship. | 11-26-2009 |
20120325177 | LUBRICATION STRUCTURE OF CRANKING ROTATIONAL FORCE TRANSMISSION MECHANISM FOR INTERNAL COMBUSTION ENGINE - The lubricant-return holes are provided in the intermediate portion of the ring gear. Thus, the lubricant stagnating above the first oil sealing member can be easily discharged to the oil pan side via the lubricant-return holes even when the ring gear has stopped rotating in response to the starter motor being turned off after completion of the start of the internal combustion engine. As such, the level of the surface of lubricant stagnating between the ring gear and the outer race member does not rise, and therefore the lubricant surface virtually does not reach the outer race and the one-way clutch that are rotating while the internal combustion engine is running. Thus, bubbling of lubricant and production of sludge, which may otherwise be caused by agitation of the lubricant surface, can be prevented. | 12-27-2012 |
