1.换车库门弹簧

以前写的一篇没了,只好再写一篇,因为又有一个车库门弹簧断了。以前换的那个,车库天花板很低,开门器是我把天花板割开一呎宽数呎长埋进去装的。结果换弹簧时上面winding bar顶到天花板,下面的被门的strut挡住插不进去,把车库门最上面那片拆了才换好;现在看来拆strut兴许也行。如何测量:http://ddmgaragedoors.com/diy-instructions/how-to-measure-torsion-springs.php  需要在非张紧态下量钢丝直径(=长度/圈数),弹簧内径,长度和左右方向。方向可用左右手判断如下图为右向,其中大拇指埋入代替轴。有的还需注意特殊尾端形状。

正常情况下,在车库外面向车库时,左右侧弹簧是left/right wind,且右侧漆红。测得Fremont为常态左右绕向,右侧断了为共120圈,内径1-3/4吋,长约28-3/4吋,张紧后长31-1/8吋;左侧没断张紧后有142圈长34-3/4吋。由28.75/120~=0.24吋钢丝,张紧伸长对7呎高门为(丝径*8)+1/4=2-1/4吋,28.75+2.25=31与量得31-1/8相近。若换两根可取平均长度(31+34.75)/2-2.25~=31吋,也可取标准32吋。

网购:https://www.365garagedoorparts.net Amazon国产品价低,实际买的这个带winding bar,质量与美公司网上卖的一样。

如何换:http://www.mitbbs.com/article_t/Texas/31507023.html  油管搜garage door torsion spring replacement。工具包括1/2" winding bar、夹钳各2个,扳手等。断电、松开电动机构(有拉绳)并用夹钳在门侧轨上防止门上移超过4吋;卸装弹簧都需winding bar交替抵在门上每次松开1/4圈;亦须卸掉两侧滑轮,注意先标记带轮轴向位置、钢绳是垂于轮子外侧还是内测;两弹簧中间是黑胶或滚珠轴承可考虑换;装上弹簧和滑轮钢丝后,滑轮和弹簧螺栓都是手紧再1/2~3/4圈,先按标记固定滑轮螺栓;再将弹簧用winding bar每次1/4圈张紧,7呎门弹簧张紧31次(https://www.youtube.com/watch?v=KTpNET1VbJE ),以门不上移且两侧接地为度,之前可喷白漆以便计数;松开门侧夹钳,手动开关门,开门少许或全开都能自停。最后加电测试。

实践小结:先松没断的弹簧,用winding bar下置挡在车门上。发现所有的固定螺栓都把主轴管压变形了,要榔头把弹簧/带轮敲下来,然后敲击轴管两螺丝压痕的中间让管子复原一些,不然弹簧通不过去。我喷的漆由于事后喷WD40使轴管润滑都看不见了,带轮按原有螺丝压痕固定。绕好钢丝,用卡钳固定轴管使得张紧弹簧时轴管不转,不然钢丝会松。没有预松电动机构,弹簧预紧31次,是手往上举winding bar。结果松开电动机构后门大力上开!因此用卡夹限定上移几寸很有必要,松开卡钳时注意上弹。

把每侧弹簧都松2次(总29*1/4圈)后正常,门可手动停在任何位置。原中置轴承没装对,没卡在中置bracket的大孔中,这次纠正了。因此,先松开电动机构卡子,用夹钳在4吋上限位是正解,预紧时门上移可及时发现。

2. Hinge

垂直分为四片的铁门由上至下的Hinge号码分别是#3/#2/#1,因滑道不是垂直的。断裂的Hinge直接拧螺丝更换。租客换的似乎不对,门变形手动很难开关电动更没戏。找人装2个struts价格350: https://www.youtube.com/watch?v=R1BBNQufXCw。注意:加厚更重弹簧要重调上紧。https://www.menards.com/main/doors-windows-millwork/garage-doors-garage-door-openers/garage-door-parts-accessories/ideal-door-reg-2-x-16-ft-steel-horizontal-garage-door-support-strut/p-1444433865176.htm 本地店找到了:(408) 676-9201
750 Camden Ave., Unit-C, Campbell, CA 95008 两根50刀。需7/16" SelfTapping screws. Hinge至少要14gauge的1.98mm,#11的更好3.175mm。

这就是以前换的那个,车库天花板很低,开门器是我把天花板割开14.5吋宽8呎多长埋进去装的。没有锯2x4因此装的偏了几吋,门被拉变形了。现在看来拉力臂还是要装在正中,正中的ceiling joist 2x4锯断后,少了一根而且两侧加固较麻烦,因为要20呎的料还要人爬进去装。不如把锯断的2x4横搭在开口处与原有间隔16吋的2x4的正交固定,还可以在两侧ceiling joist上加木板固定在roof rafter上。通常,开门机轨道端头装在弹簧上方可以高些,然后开门在门上垫2x4放置电机轨道,如此有1.5吋间隙。光电头居地不超过6吋,对准时接收端绿灯会亮,黄灯是发送端电源。
