谢谢stevenw。你的一句话使我下决心拆开机器盒子。发现是因为常年磨损,电机边的朔料齿轮磨小了(边上有一大堆白花花的朔料渣),电机正常转动时,电机头上的齿轮挨不着带动链条的白色齿轮,带动不起来车库门(图中白色的朔料齿轮)。见下面照片。有一种可能,电机边上的齿轮齿打坏了,在机器盒子里面。
这一般是你多年不给轨道喷油造成的。
You can get new gears by online shopping. It will be more cheaper.
My garage door has the same issue last year. My husband got 3 pieces of gear from a US website. It costs only several bucks. Of course, my hubby is very handy. He is enjoying to fix some mechanical issue. It is one of reasons I married with him![]()
建议找人调一下车库门的弹簧。如果车库门loading不平衡,会overload openner。塑料齿轮用不了多久又会坏。
检查车库门loading是否合适可以把链条取下来,手动开关车库门,开关都应该不费力
应该是黑心的设计。如果opener能够用100年,生产厂家早就倒闭了。
