检查

检查交流发电机皮带和风扇传动皮带是否磨损和有裂纹。 如果皮带不是在良好状态,要更换皮带。

依据维修手册, "技术规格",检查皮带张紧度。

皮带松造成的滑动会降低被驱动部件的效率。 皮带松引起的振动可能造成下列部件的不必要磨损:

  • 皮带

  • 皮带轮

  • 轴承

如果皮带太紧,对部件会造成不必要的应力。 不必要的应力会缩短部件的使用寿命。

注: 务必确保更换散热器上的风扇罩,以使风扇周围的间距均匀。 确保启动时,风扇不与风扇罩接触。

更换

对于需要多根驱动皮带的应用,应成套更换驱动皮带。 只更换成套皮带中的一根驱动皮带会因为旧驱动皮带已拉长而使新驱动皮带承受更多的负载。 新驱动皮带的额外负载会造成新驱动皮带损坏。

风扇传动皮带的调整

  1. 拆下传动皮带护罩。

  1. 松开皮带轮的固定螺栓。

  1. 松开皮带轮的调整螺母。

  1. 移动皮带轮以调整皮带张紧度。

  1. 拧紧调整螺母。

  1. 拧紧固定螺栓。

  1. 重新安装传动皮带护罩。

    如果安装新传动皮带,应在发动机以额定转速运转 30 分钟后再次检查皮带张紧度。
