为使发动机性能最大化,检查传动皮带是否磨损和断裂。 检查皮带张紧力。 调整传动皮带的张紧度以便使皮带打滑最低化。 皮带打滑将降低传动皮带的使用寿命。
关于皮带的正确张紧度,请参阅规格, "皮带张紧度图表"。
调整
- 拆下皮带盖。
- 松开安装螺栓 (1) 和调整螺栓 (2) 。
- 把交流发电机往能达到正确张紧度的方向移动。
- 拧紧调整螺栓 (2) 。 拧紧安装螺栓 (1) 。 关于正确的扭矩,参见技术规格, SENR3130, "扭矩规格"。
- 把皮带盖装回去。
如果安装新皮带,应在发动机以额定转速运行30分钟后再次检查皮带张紧度。
更换多皮带传动装置的皮带
对于需要多根传动皮带的应用,要更换相配的整组传动皮带。 由于旧皮带已被拉伸,只更换一组中的一条皮带会使新皮带承受更多的负载。 额外负荷就会加到新皮带上,从而造成皮带断裂。
