The electric wrench is not the stronger the voltage is.

1、勁大，代表扭矩大。

1. Great strength means great torque.

2、電機(jī)和減速器的扭矩（N·m）= 電機(jī)額定功率（W）/(2 * π * 轉(zhuǎn)速/60)。

2. Torque of motor and reducer (n · m) = rated power of motor (W) / (2 * π * speed / 60).

3、從第2條可以看出，電機(jī)功率越大，轉(zhuǎn)速越低，扭矩越大，操作中轉(zhuǎn)速一般不會(huì)差異很大，關(guān)鍵就在于電機(jī)功率的大小了。

3. It can be seen from Article 2 that the higher the power of the motor, the lower the rotation speed and the greater the torque. Generally, the rotation speed will not vary greatly during operation. The key lies in the power of the motor.

4、電壓大對(duì)于減少電流，降低能耗有益，但會(huì)使電池?cái)?shù)量、重量、體積增加。

4. Large voltage is beneficial to reduce current and energy consumption, but it will increase the number, weight and volume of batteries.

在生產(chǎn)生活中我們經(jīng)常會(huì)發(fā)現(xiàn)，用于連接緊固的螺栓在經(jīng)過(guò)一段時(shí)間后松動(dòng)了，要知道螺栓松動(dòng)可造成的影響有大有少，為了防止螺栓松動(dòng)，我們應(yīng)該怎么做呢？防止螺栓松動(dòng)有幾種方法？下面沃頓液壓扳手來(lái)介紹一下。

In production and life, we often find that the bolts used for connection and fastening are loosened after a period of time. We should know the impact of bolt loosening. What should we do to prevent bolt loosening? How many methods are there to prevent bolts from loosening? Wharton hydraulic wrench is introduced below.

一、螺栓松動(dòng)的影響:

1、 Effect of bolt loosening:

一顆螺栓松動(dòng)可能會(huì)致使整個(gè)生產(chǎn)設(shè)備陷入停滯狀態(tài)，并使企業(yè)遭受損失巨大，甚在一些應(yīng)用中，松動(dòng)的螺栓會(huì)導(dǎo)致嚴(yán)重的事故發(fā)生。那么為了防止螺栓松動(dòng)，我們應(yīng)該怎么做呢？防止螺栓松動(dòng)有幾種方法？

A loose bolt may cause the whole production equipment to stagnate, and cause the enterprise to suffer huge losses. Even in some applications, a loose bolt may cause serious safety accidents. So what should we do to prevent the bolts from loosening? How many methods are there to prevent bolts from loosening?

二、防止螺栓松動(dòng)有幾種方法：

2、 There are several methods to prevent bolt loosening:

液壓扳手根據(jù)防松原理可以分為靠摩擦力、直接鎖住和破壞螺紋運(yùn)動(dòng)關(guān)系三種。

According to the anti loosening principle, hydraulic wrenches can be divided into three types: relying on friction, directly locking and destroying the thread movement relationship.

1.摩擦防松：在螺紋副間產(chǎn)生一個(gè)不隨外力變化的正壓力，以產(chǎn)生一個(gè)可以阻止螺紋副相對(duì)轉(zhuǎn)動(dòng)的摩擦力。這種正壓力可以通過(guò)軸向或橫向或同時(shí)兩向壓緊螺紋副來(lái)實(shí)現(xiàn)。

1. Friction anti loosening: a positive pressure that does not change with the external force is generated between the thread pairs to generate a friction force that can prevent the relative rotation of the thread pairs. This positive pressure can be achieved by axially or laterally or simultaneously pressing the screw pair in two directions.

2.直接鎖?。河弥箘?dòng)件直接限制螺紋副相對(duì)轉(zhuǎn)動(dòng)。

2. Direct locking: use the stopper to directly restrict the relative rotation of the thread pair.

3.破壞螺紋運(yùn)動(dòng)關(guān)系：在擰緊后采用沖點(diǎn)、焊接、粘結(jié)等方法，使螺紋副失去運(yùn)動(dòng)特性而連接成為不可拆卸的連接。

3. Destroy the thread movement relationship: after tightening, punch point, welding, bonding and other methods are adopted to make the thread pair lose its movement characteristics and become a non detachable connection.

采用細(xì)牙螺紋，利用其升角小而達(dá)成摩擦防松或同時(shí)采取兩種防松方法，互為補(bǔ)充等，都是較好的設(shè)計(jì)構(gòu)思。航空航天機(jī)械用螺栓螺母其螺紋直徑大于十mm的和許多承受變載的機(jī)械用螺栓螺母，都采用細(xì)牙的原因之一也在此。常用液壓扳手螺紋連接的防松方法和技巧，對(duì)螺釘連接和雙頭螺柱連接也適用。液壓拉伸器與液壓扳手都是緊固拆卸螺栓的重要工具，它們廣泛應(yīng)用于船舶，石油化工，建筑，電力，礦山，冶金等行業(yè)的施工，維檢，搶修等工作中。它們的使用不僅可以減輕勞動(dòng)強(qiáng)度，提高工作效率，而且極大的提高安裝質(zhì)量，也有利于施工現(xiàn)場(chǎng)及工作效率的管理。

It is a good design idea to adopt fine thread, use its small rise angle to achieve friction anti loosening, or adopt two anti loosening methods at the same time to complement each other. This is one of the reasons why fine teeth are used for bolts and nuts for aerospace machinery, whose thread diameter is more than 10 mm, and many bolts and nuts for machinery under variable loads. The anti loosing methods and techniques of common hydraulic wrench thread connection are also applicable to screw connection and double headed stud connection. Hydraulic tensioner and hydraulic wrench are important tools for fastening and disassembling bolts. They are widely used in the construction, maintenance and repair of shipbuilding, petrochemical, construction, electric power, mining, metallurgy and other industries. Their use can not only reduce the labor intensity and improve the work efficiency, but also greatly improve the installation quality, which is also conducive to the management of safety and work efficiency at the construction site.
