    • PROBLEM TO BE SOLVED: To provide a highly reliable gear device in which in the case a backlash is allowed to be relatively large, a tooth contact impact when a tooth surface contacts is buffered, and further a coaxiality accuracy is kept between a gear and a gear shaft, tooth contact noise of the gear and engaging noise are decreased, thereby a tooth surface damage due to a biased contact etc. is not caused, and the gear does not fall off by variable load in a shaft direction, regarding a device in which an amplitude of a vibrational torque transmitted by a gear is higher than a static torque.SOLUTION: There is provided an engine balancer comprised of a drive gear 3, a drive shaft 1 and a driven gear 4 and comprised of a gear pair having the drive gear 3 and the driven gear 4 engaged to each other in which the drive gear 3 is fitted to the drive shaft 1 and there is provided a fixture for elastically fixing the drive gear 3 and the drive shaft 1 to each other.
    • 要解决的问题:为了提供一种高度可靠的齿轮装置,其中在使齿隙相对较大的情况下,当齿面接触缓冲时的齿接触冲击,并且进一步保持齿轮与齿轮之间的同轴度精度 齿轮轴,齿轮的齿接触噪声和接合噪声降低,从而不会引起由于偏置接触等引起的齿面损伤,并且齿轮在轴向方向上不会由于可变负载而脱落, 由齿轮传递的振动扭矩的振幅高于静态扭矩。解决方案:提供了一种由驱动齿轮3,驱动轴1和从动齿轮4组成的发动机平衡器,包括具有 驱动齿轮3和从动齿轮4彼此接合,其中驱动齿轮3与驱动轴1配合,并且设置有用于将驱动齿轮3和驱动轴1彼此弹性固定的固定装置。
