一、启动时有强烈打齿声。主要有以下原因造成的: 1.开关接通过早。齿轮尚未与飞轮齿圈啮合,主电路就已接通,齿轮在高速旋转的情况下与齿圈接合,造成两齿轮强烈撞击而发出很响的打齿声。 2、单向离合器压力弹簧不足。该弹簧弹力不足时,即使开关接通时间正常,也会发生强烈打齿声。 3.飞轮齿圈或驱动轮齿损坏导致啮合困难。 First, there is a strong tooth when starting. Mainly due to the following reasons: 1. Switch connected too early. The gear has not yet engaged with the flywheel ring gear, the main circuit has been connected, the gear engaged with the ring gear in the case of high speed rotation, resulting in a strong collision of the two gears and a very loud beating sound. 2, one-way clutch pressure spring is not enough. When the spring is not strong, even if the switch on time is normal, there will be a strong tooth hit. 3. Flywheel ring gear or drive gear tooth damage resulting in difficult to engage.
