    • In double tapered rollers of a thrust scroll bearing, a structure free from generation of edge load at both ends of a section straight line on conical or tapered surfaces, and appropriate in contact stress with the bearing race is presented. To be used as a rolling element of thrust bearing interposed between positions making relative scroll motions, it is a conical body having a pair of conical surfaces (Ra, Rb) matched coaxially and coupled at bottoms mutually, and the entire surface of the conical surfaces (Ra, Rb) is processed by crowning. As a result, edge load is not generated at both ends of the section straight line of the conical surfaces (Ra, Rb), and the maximum contact stress at the apex side is held at a low value within an allowable range.
    • 在推力涡旋轴承的双锥形滚子中,提出了一种在锥形或锥形表面上的截面直线两端不产生边缘载荷的结构,并且与轴承座圈接触应力适当。 为了被用作推动轴承的滚动元件插入在进行相对滚动运动的位置之间,它是一个圆锥体,它具有一对锥形表面(Ra,Rb),它们同轴同轴并在底部相互匹配,并且锥形表面的整个表面 (Ra,Rb)通过加冠处理。 结果,在圆锥面(Ra,Rb)的截面直线的两端不产生边缘载荷,并且顶点侧的最大接触应力保持在允许范围内的低值。

    • In a speed transition period from when an internal combustion engine is started to when an engine speed settles down to a certain speed, a compression top dead center of a cylinder first operating is set as a reference crank angle and compression top dead centers of the cylinders arriving successively after said reference crank angle in the speed transition period are set as judgment use crank angles. Reference crank angle advancing times are detected and stored in advance, wherein the reference crank angle advancing times are crank angle advancing times when a reference fuel is used, and the crank angle advancing times are times required for the crank angle to advance from the reference crank angle to the judgment use crank angles. The actual crank angle advancing times are detected. When an actual crank angle advancing time is shorter than the reference crank angle advancing time, the ignition timing is retarded by an amount corresponding to a difference of the actual crank angle advancing time from the reference crank angle advancing time. When the actual crank angle advancing time is longer than the reference crank angle advancing time, the ignition timing is advanced by an amount corresponding to the difference.
    • 在从内燃机起动到发动机转速稳定到一定速度的转速过渡期间,将第一运转的气缸的压缩上止点设定为基准曲柄角,并将气缸的压缩上止点设定 在速度转换期间的所述基准曲柄角之后连续地设定为判定用曲柄角。 参考曲柄角前进时间被预先检测并存储,其中参考曲柄角行进时间是使用参考燃料时的曲柄角行进时间,并且曲轴转角提前时间是曲轴转角从参考曲柄 角度与判断使用曲柄角度。 检测实际的曲柄角行进时间。 当实际的曲柄角行进时间比参考曲柄角前进时间短时,点火正时被延迟与实际曲柄角前进时间与基准曲柄角行进时间的差对应的量。 当实际的曲柄角行进时间比参考曲柄角前进时间长时,点火正时提前一个对应于该差的量。

    • A roller bearing of high precision structure at a far lower cost as compared with the prior art, having double tapered rollers as rolling elements. It comprises a fixed side bearing plate, a swivel side bearing plate, plural double tapered rollers disposed between both bearing plates so as to swivel and roll between them for supporting the axial load from both bearing plates, a holding plate for positioning and holding the double tapered rollers rotatably in a specified configuration, and a revolution arrester for preventing relative rotation of both bearing plates. While preventing relative rotation of the both bearing plates by the revolution arrester, the double tapered rollers are allows to roll and move on the bearing plates, so that relative and smooth swivel of both bearing plates may be assured.
    • 与现有技术相比,具有高精度结构的滚子轴承成本低廉,具有作为滚动元件的双锥形滚子。 它包括固定侧支承板,旋转侧支承板,设置在两个支承板之间的多个双锥形滚子,以便在它们之间旋转和滚动以支撑来自两个支承板的轴向载荷,用于定位和保持双 以特定构造可旋转的圆锥滚子,以及用于防止两个支承板相对旋转的旋转避雷器。 同时通过避雷器防止两个支承板相对旋转,双锥形滚子允许在支承板上滚动和移动,从而可以确保两个支承板的相对平滑的旋转。
