1.換車庫門彈簧

以前寫的一篇沒了,隻好再寫一篇,因為又有一個車庫門彈簧斷了。以前換的那個,車庫天花板很低,開門器是我把天花板割開一呎寬數呎長埋進去裝的。結果換彈簧時上麵winding bar頂到天花板,下麵的被門的strut擋住插不進去,把車庫門最上麵那片拆了才換好;現在看來拆strut興許也行。如何測量:http://ddmgaragedoors.com/diy-instructions/how-to-measure-torsion-springs.php  需要在非張緊態下量鋼絲直徑(=長度/圈數),彈簧內徑,長度和左右方向。方向可用左右手判斷如下圖為右向,其中大拇指埋入代替軸。有的還需注意特殊尾端形狀。

正常情況下,在車庫外麵向車庫時,左右側彈簧是left/right wind,且右側漆紅。測得Fremont為常態左右繞向,右側斷了為共120圈,內徑1-3/4吋,長約28-3/4吋,張緊後長31-1/8吋;左側沒斷張緊後有142圈長34-3/4吋。由28.75/120~=0.24吋鋼絲,張緊伸長對7呎高門為(絲徑*8)+1/4=2-1/4吋,28.75+2.25=31與量得31-1/8相近。若換兩根可取平均長度(31+34.75)/2-2.25~=31吋,也可取標準32吋。

網購:https://www.365garagedoorparts.net Amazon國產品價低,實際買的這個帶winding bar,質量與美公司網上賣的一樣。

如何換: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、夾鉗各2個,扳手等。斷電、鬆開電動機構(有拉繩)並用夾鉗在門側軌上防止門上移超過4吋;卸裝彈簧都需winding bar交替抵在門上每次鬆開1/4圈;亦須卸掉兩側滑輪,注意先標記帶輪軸向位置、鋼繩是垂於輪子外側還是內測;兩彈簧中間是黑膠或滾珠軸承可考慮換;裝上彈簧和滑輪鋼絲後,滑輪和彈簧螺栓都是手緊再1/2~3/4圈,先按標記固定滑輪螺栓;再將彈簧用winding bar每次1/4圈張緊,7呎門彈簧張緊31次(https://www.youtube.com/watch?v=KTpNET1VbJE ),以門不上移且兩側接地為度,之前可噴白漆以便計數;鬆開門側夾鉗,手動開關門,開門少許或全開都能自停。最後加電測試。

實踐小結:先鬆沒斷的彈簧,用winding bar下置擋在車門上。發現所有的固定螺栓都把主軸管壓變形了,要榔頭把彈簧/帶輪敲下來,然後敲擊軸管兩螺絲壓痕的中間讓管子複原一些,不然彈簧通不過去。我噴的漆由於事後噴WD40使軸管潤滑都看不見了,帶輪按原有螺絲壓痕固定。繞好鋼絲,用卡鉗固定軸管使得張緊彈簧時軸管不轉,不然鋼絲會鬆。沒有預鬆電動機構,彈簧預緊31次,是手往上舉winding bar。結果鬆開電動機構後門大力上開!因此用卡夾限定上移幾寸很有必要,鬆開卡鉗時注意上彈。

把每側彈簧都鬆2次(總29*1/4圈)後正常,門可手動停在任何位置。原中置軸承沒裝對,沒卡在中置bracket的大孔中,這次糾正了。因此,先鬆開電動機構卡子,用夾鉗在4吋上限位是正解,預緊時門上移可及時發現。

2. Hinge

垂直分為四片的鐵門由上至下的Hinge號碼分別是#3/#2/#1,因滑道不是垂直的。斷裂的Hinge直接擰螺絲更換。租客換的似乎不對,門變形手動很難開關電動更沒戲。找人裝2個struts價格350: https://www.youtube.com/watch?v=R1BBNQufXCw。注意:加厚更重彈簧要重調上緊。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 兩根50刀。需7/16" SelfTapping screws. Hinge至少要14gauge的1.98mm,#11的更好3.175mm。

這就是以前換的那個,車庫天花板很低,開門器是我把天花板割開14.5吋寬8呎多長埋進去裝的。沒有鋸2x4因此裝的偏了幾吋,門被拉變形了。現在看來拉力臂還是要裝在正中,正中的ceiling joist 2x4鋸斷後,少了一根而且兩側加固較麻煩,因為要20呎的料還要人爬進去裝。不如把鋸斷的2x4橫搭在開口處與原有間隔16吋的2x4的正交固定,還可以在兩側ceiling joist上加木板固定在roof rafter上。通常,開門機軌道端頭裝在彈簧上方可以高些,然後開門在門上墊2x4放置電機軌道,如此有1.5吋間隙。光電頭居地不超過6吋,對準時接收端綠燈會亮,黃燈是發送端電源。
