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、電機和減速器的扭矩（N·m）= 電機額定功率（W）/(2 * π * 轉速/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，電機功率越大，轉速越低，扭矩越大，操作中轉速一般不會差異很大，關鍵就在于電機功率的大小了。

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、電壓大對于減少電流，降低能耗有益，但會使電池數(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)常會發(fā)現(xiàn)，用于連接緊固的螺栓在經(jīng)過一段時間后松動了，要知道螺栓松動可造成的影響有大有少，為了防止螺栓松動，我們應該怎么做呢？防止螺栓松動有幾種方法？下面沃頓液壓扳手來介紹一下。

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、螺栓松動的影響:

1、 Effect of bolt loosening:

一顆螺栓松動可能會致使整個生產(chǎn)設備陷入停滯狀態(tài)，并使企業(yè)遭受損失巨大，甚在一些應用中，松動的螺栓會導致嚴重的事故發(fā)生。那么為了防止螺栓松動，我們應該怎么做呢？防止螺栓松動有幾種方法？

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動關系三種。

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)生一個不隨外力變化的正壓力，以產(chǎn)生一個可以阻止螺紋副相對轉動的摩擦力。這種正壓力可以通過軸向或橫向或同時兩向壓緊螺紋副來實現(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?。河弥箘蛹苯酉拗坡菁y副相對轉動。

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

3.破壞螺紋運動關系：在擰緊后采用沖點、焊接、粘結等方法，使螺紋副失去運動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.

采用細牙螺紋，利用其升角小而達成摩擦防松或同時采取兩種防松方法，互為補充等，都是較好的設計構思。航空航天機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械用螺栓螺母，都采用細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強度，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.
