扭力扳手的用處也是特別多的，包括現(xiàn)在的汽車維修方面也會用到扭力扳手，車上每顆螺絲都有標準扭矩，拆卸安裝螺絲標準的操作應(yīng)該使用扭矩扳手，輪胎螺絲也有標準扭矩，這兩處是整個車拆裝比較頻繁的螺絲，但是維修技師一般都會用普通的扳手去緊固，時間長了油底殼螺絲就壞了，這不是因為拆卸次數(shù)多造成的，是因為緊固時沒有用扭矩扳手，導(dǎo)致螺絲的過擰而造成的。所以在維修的時候可以選用扭力扳手，小編給大家總結(jié)了一些扭力扳手的好處，大家可以看一下
Torque wrenches are also very useful. Torque wrenches are also used in current automobile maintenance. Each screw on the car has a standard torque. Torque wrenches should be used for standard operation of removing and installing screws. Tire screws also have a standard torque. These two screws are frequently disassembled and disassembled in the whole car, but maintenance technicians usually use ordinary wrenches to tighten them, The oil pan screws broke after a long time. This is not caused by too many disassembly times, but because the screws were over tightened without a torque wrench. Therefore, torque wrench can be selected during maintenance. Xiaobian summarized some benefits of torque wrench for you to have a look
為什么有些維修技師不太愛用扭矩扳手？有三方面原因，一是經(jīng)驗豐富，對力矩的把握比較準確，也知道緊固這個螺絲需要用多大的力，緊固完后與標準扭矩相差無幾。二是偷懶的做法，用扭矩扳手緊固比較麻煩，每次緊固螺絲都要去調(diào)整。三是大部分螺絲就算沒有達到標準扭矩，影響也不大，不會影響車的使用。
Why do some maintenance technicians not like to use torque wrench? There are three reasons. First, he has rich experience and has a relatively accurate grasp of the torque. He also knows how much force it takes to tighten the screw. After tightening, it is almost the same as the standard torque. Second, it is lazy. It is troublesome to tighten with a torque wrench. The screws must be adjusted every time. Third, even if most screws do not reach the standard torque, the impact is not great and will not affect the use of the car.
如果每次都不按標準扭矩來，時間久了有什么危害呢？我們就拿油底殼螺絲來說，如果扭矩太小，會有滲油現(xiàn)象。扭矩太大，螺絲會被拉長，久而久之也會滲油，甚螺絲還會斷裂。更嚴重的還會把絲圈損壞，不只是要更換螺絲，還要對油底殼重新套絲，工程量比較大。實際上緊固油底殼螺絲，絕大部分人都會超過標準扭矩，也就是緊固的太緊了，甚下次拆卸都不容易拆。有的拆下來直接就拆壞了，這就是上次緊固太緊造成的。油底殼螺絲大約也就二三十牛米的力矩，用很小的力緊一下就可以。輪胎螺絲也是相同的道理，很多輪胎螺絲斷了或者拆不下來，都是上次緊固時用的力太大了造成的。不管哪里的螺絲，只要沒有用扭力扳手緊固的，大部分都會擰得過緊，超過標準扭矩。
If you don't follow the standard torque every time, what harm will it do after a long time? Take the oil pan screw for example. If the torque is too small, there will be oil leakage. If the torque is too large, the screw will be elongated, oil will leak over time, and even the screw will break. Even more serious, the wire ring will be damaged. It is not only necessary to replace the screws, but also to re thread the oil pan, with a large amount of work. In fact, when tightening the oil pan screws, most people will exceed the standard torque, that is, the tightening is too tight, and it is not easy to remove them next time. Some of them are broken when they are removed. This is because they were tightened too tightly last time. The torque of the oil pan screw is about 20 or 30 nm. Tighten it with a small force. The same is true for tire screws. Many tire screws are broken or cannot be removed, which is caused by too much force when tightening last time. No matter where the screws are, as long as they are not tightened with a torque wrench, most of them will be over tightened and exceed the standard torque.
所以關(guān)鍵部位還是需要用到扭力扳手，比如缸蓋螺絲，大小瓦螺絲。還有比較常見的氣門室蓋螺絲，很多車氣門室蓋墊容易漏油，更換需要拆卸氣門室蓋。因蓋子上螺絲非常多，如果不用扭力扳手，會導(dǎo)致每顆螺絲的力矩不一樣大，也就是有的緊有的松，這樣會導(dǎo)致氣門室墊壽命縮短，用不了多長時間又會滲油。而用扭力扳手可以 工作的質(zhì)量，避免出現(xiàn)后續(xù)的糾紛
Therefore, torque wrenches are still needed in key parts, such as cylinder head screws and large and small tile screws. There are also common valve cover screws. The valve cover gasket of many vehicles is easy to leak oil. The valve cover needs to be removed for replacement. Because there are many screws on the cover, if you don't use a torque wrench, the torque of each screw will be different, that is, some are tight and some are loose, which will shorten the service life of the valve pad and leak oil in a short time. The use of torque wrench can improve the quality of work and avoid subsequent disputes
