摘要： A one-way clutch and a bearing are both grease-filled so even if an oil seal member prevents engine oil from flowing thereto, it will cause no problems in terms of lubrication of the one-way clutch and the bearing. Therefore, the oil seal member 18 need only seal between a main body side of an internal combustion engine and a crankshaft and so does not need to have a large diameter. As a result, even when the crankshaft rotates while the internal combustion engine is operating, the small diameter oil seal member will not slide at a high rate of speed against an outer peripheral surface of the crankshaft and so will not degrade quickly.
摘要翻译：单向离合器和轴承都是润滑脂，因此即使油封构件防止发动机油流动，也不会在单向离合器和轴承的润滑方面产生问题。因此，油封构件18仅需要在内燃机的主体侧和曲轴之间进行密封，因此不需要具有大的直径。结果，即使在内燃机运转时曲轴旋转的情况下，小直径油封构件也不会以相对于曲轴的外周面的高速度滑动，因此不会迅速劣化。

摘要： The lubricant-return holes (12d) are provided in the intermediate portion (12c) of the ring gear (12), Thus, the lubricant stagnating above the first oil sealing member (32) can be easily discharged to the oil pan (36) side via the lubricant-return holes (12d) even when the ring gear (12) 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 (12) and the outer race member (14) does not rise, and therefore the lubricant surface virtually does not reach the outer race (30) and the one-way clutch (20) 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.

摘要： A starter for an internal combustion engine includes a power transmission mechanism (60). The power transmission mechanism (60) has an outer race plate (20) fastened to a crankshaft (11), and a ring gear (30) coupled to a rotational shaft of an electric motor for starting the engine. The power transmission mechanism (60) further has a one-way clutch (50) for permitting torque transmission only from the ring gear (30) to the outer race plate (20), and two sealing members (61, 62). Lubricant is supplied from the cylinder block (12) to the interior of the power transmission mechanism (60) for lubricating the power transmission mechanism (60). The outer race plate (20) has a groove (22) on its contact surface (20a) of a contact portion between the crankshaft (11) and the outer race plate (20). The groove (22) extends in the entire circumferential direction of the crankshaft (11). This maintains the coupling strength between the outer race plate (20) and the crankshaft (11), while enhancing the sealing performance of the power transmission mechanism.

摘要： A construction width region (Aowc) of a one-way clutch (14) overlaps with a mesh width region (Agg) where torque is transferred from a pinion (20) to a ring gear (12) at the time of startup of the engine, so that the center positions of the two regions in the direction of the rotation axis coincide with each other. Due to this overlap, the reaction force that occurs on a one-way clutch (14) when torque is transferred from the pinion (20) to the ring gear (12) can be sufficiently restrained from becoming, together with the torque, a force that inclines the rotation axis of the ring gear (12). Therefore, it is possible to restrain the direction of engagement force from lilting from a noπnal position relative to a sprag or the like of the one-way clutch (14), and to sufficiently prevent occurrence of bad engagement. Furthermore, damages, such as impressions inside a bearing (18) and the like, and deformations of oil seal portions (24, 26) can be prevented.
摘要翻译：单向离合器（14）的结构宽度区域（Aowc）与转矩从小齿轮（20）传递到齿圈（12）的网孔宽度区域（Agg）重叠，在发动机起动时，两个区域的旋转轴方向的中心位置一致。由于这种重叠，当转矩从小齿轮（20）传递到齿圈（12）时，在单向离合器（14）上产生的反作用力能够被充分地抑制成不与转矩一起产生力使齿圈（12）的旋转轴线倾斜。因此，可以抑制啮合力的方向相对于单向离合器14的楔块等从极端位置倾斜，并且充分防止发生啮合不良。此外，可以防止诸如轴承（18）等内部的压痕以及油封部分（24,26）的变形的损坏。

摘要： A ring gear is formed by joining a race side-region formed body (26), a gear side-region formed body (28) and an intermediate region formed body (30). Accordingly, it is possible to perform processing of an inner race portion (2b) of the race side-region formed body (26) with none of the gear side-region formed body (28) and the intermediate region formed body (30) present. By causing the gear side-region formed body (28) and the intermediate region formed body (30) 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 (26) for various engine types. Because the inner race portion (2b), as well as a disposition surface (2d) and a contact surface (2e) for the seal rings are formed on the same race side-region formed body (26), it is possible to finish the surfaces with precise positional relationship.

摘要： An outer race support plate to which torque of a pinion gear (20) is transmitted from a ring gear (12) via a one-way clutch (14) and thus rotates a crankshaft is provided separately from a flywheel (8) and is mounted to the crankshaft not via the flywheel. As a result, impact noise produced when the one-way clutch engages is not directly transmitted to the flywheel. Accordingly, noise radiation from the flywheel can be suppressed, thereby enabling noise to be reduced.

摘要： Engine starting apparatus comprising a one way clutch. A first oil seal is located on the outer side of a second oil seal in the radial direction of a ring gear. Upon starting of an engine, the time that the first oil seal is slid on the ring gear is short, and after the start of the engine, the first oil seal is not slid on the ring gear. The second oil seal is located on the inner side of the first oil seal in the radial direction of the ring gear. Therefore, the second oil seal hardly deteriorates even if slid on a flywheel at high speed after the start of the engine. By locating the first and second oil seals at different positions in the radial direction of the ring gear, it is possible to improve the startability and the lifetime of a starting apparatus. At least one oil seal has a taper shape in order to generate a thrust sorce which forces the ring gear away from the flywheel.
摘要翻译：发动机起动装置，包括单向离合器。第一油封位于第二油封的外侧沿齿圈的径向方向。发动机起动时，第一油封在齿圈上滑动的时间短，在发动机起动之后，第一油封不会在齿圈上滑动。第二油封沿着齿圈的径向位于第一油封的内侧。因此，即使在发动机起动之后高速地在飞轮上滑动，第二油封也几乎不劣化。通过将第一和第二油封定位在环形齿轮的径向上的不同位置，可以提高起动装置的起动性和使用寿命。至少一个油封具有锥形形状，以便产生迫使齿圈远离飞轮的推力。
