冲击扳手和扭矩扳手之间经常混淆。购买错误的人可能是一个昂贵(可能令人尴尬的)错误。确保您在购买前了解您的需求。

Types of torque wrench

许多人会熟悉我们认为的“标准”扭矩扳手 - 看起来很像棘轮驱动套筒扳手。还有其他几个:

  • Preset torque wrenches:Also called torque drivers. Often small, gripped in the palm of the hand. They are set for a single torque amount. Popular with cyclists because of their light weight and portability.

  • 偏转光束扭矩扳手:Available in a wide variety of ranges, from light engineering to heavy industrial. A long beam runs from the head where the socket is attached, down to a scale by the grip. The deflection of this beam, left or right, indicates the amount of torque. It's a common and popular tool in many industries, but the socket is fixed. There's no ratchet action, so it can be difficult to use without plenty of space.

尽管存在一些差异,但我们大多数人都被称为千分尺扭矩扳手。

除了不同类型的扭矩扳手外,还有不同的驱动尺寸。1/2“驱动器在设计用于汽车使用的工具中很常见。通常可用的是1/4英寸,3/8“和3/4”驱动器。

Expert Tip
After use, always return your torque wrench to zero, or the lowest permitted level. Leaving it “dialed up” can put unnecessary tension on components.

Click wrenches

The most common type available. An audible click, which can also be felt by the operator through the grip, warns when the required torque is reached.

  • 优点:

性能,耐用性,易用性和价值的极佳组合。正确使用时准确。

  • Cons:

如果施加太快,则可能会过度拧紧。建议稳定压力,立即停止首次单击。用户通常认为他们需要发布并应用额外的点击“只是为了确保”。这是不正确的。

突破扳手

Very similar to click wrenches, but with a hinged section – usually near the socket head – that “breaks” when the required torque is reached.

  • 优点:

便于使用。Good durability and value. Accurate when used properly.

  • Cons:

休息后的持续压力将超过尾。有些人发现“休息”动作令人不愉快。

Cam-over wrenches

外观类似于点击扳手。具有内置的滑动机构,该机构在达到固定扭矩时释放压力。

  • 优点:

便于使用。即使有新的压力也不会超过尾。保证不受用户技能级别影响的可重复精度。

  • Cons:

复杂的机制使它们非常昂贵。

拨号扳手

At first glance, looks like a click wrench with an analog dial, but the dial is there as a guide only, and does not set torque limits.

  • 优点:

Durable. Can be very accurate.

  • Cons:

Bulky. Difficult to use. The problem with dial wrenches is that they rely on a high level of operator skill. Most have no audible warning, nor do they break or cam-over. You must watch the dial (not always easy), and react accordingly.

Digital wrenches

这些是最新的发展,并且变得非常普遍。LCD读数显示扭矩读数。随着所需的扭矩级别,“交通信号灯” LED和/或听到警告发生了变化。

  • 优点:

可以准确到四个小数点。他们的价格竞争性。有些可以存储数据以进行以后的比较和记录保存。

  • Cons:

No mechanical limit, so again, they rely on user skill. Some concerns over robustness of electronic components. Negligible advantages over mechanical alternatives.

Did you know?
When using a “click” type torque wrench, one click is all you need to tell you you've reached the desired limit. Once you've heard that click, move on to the next fixing. You'll save yourself time and effort.

扭矩测量

扭矩通常以英尺磅(英尺磅)或牛顿仪表(NM)的度量标准尺度测量。尽管不太常见,但也可以以英寸磅(英寸磅)或千克(kg。cm。)(kg。cm。)进行测量。

机械扭矩扳手将具有其中一个或两个鳞片(通常是英镑和/或牛顿仪表)。

通常可以为所有这些模型设置数字模型,但并非总是如此。不要这样。

Torque wrench range and accuracy

The most popular torque wrench is the click-type, or its digital counterpart, so those are what we have focused on with our recommendations. However, the following rules and characteristics can be applied to any kind of torque wrench.

The accuracy of a torque wrench should be stated as either:

  • 全尺度(FS)或

  • Indicated Value (IV).

This can be a little confusing.

例如,引用+/- 4%在整个比例尺上的扭矩扳手可能比沿刻度(通常较低的扭矩设置)在某些点(通常是较低的扭矩设置)的扭矩扳手。其总体平均准确性为+/- 4%。

在任何指示的值下,引用+/- 4%的工具,其规模上的任何位置都不超过4%。它比引用全尺度的一个更准确。

This distinction isn't always made clear by manufacturers. Whether this is important to you will depend on the precision your job requires. If it's a concern, check with the manufacturer before purchase.

The other important point is that with click-type torque wrenches, accuracy is not quoted over the whole range. 20% to 100% is common. This is because it's difficult for this kind of mechanism to maintain control, and therefore accuracy, at the lower end.

因此,例如,如果您的扳手的扳手范围从25到250英尺,则可能无法达到其陈述的准确性,直到达到45英尺磅(范围为20%)。如果您需要在较低的设置中准确性,则可能有必要选择较小的整体范围。从10到150英尺的扳手应在28英尺的磅上准确地工作。

Alternatively, dial-type torque wrenches can maintain accuracy from 0% to 100%. However, they are considerably more expensive.

Expert Tip
When setting a manual torque wrench, always start from zero – or the lowest setting – and work up. You'll get a more accurate setting than coming down the scale.

Torque wrench features

The popular click-type mechanical torque wrench is easy to use, but settings can slip. A locking collar (sometimes called a slip lock) prevents this from happening.

如果您使用高扭矩设置,则更长的手柄将使您能够更均匀地施加压力,从而保持更好的控制。棘轮头通常允许您使用较大的工具而不会成为问题。

塑料和橡胶握把增加了舒适性,因此您不太可能放下扭矩扳手,尤其是在寒冷的日子。

Some digital models automatically shut down if left unattended, saving battery life. Some have charge indicators. As with all electronic devices, it's an area that changes rapidly, and manufacturers like to add bells and whistles to attract you. Ask yourself whether these things are worth the extra cost, or just gimmicks.

"It is possible to use some torque wrenches for loosening, but we don’t recommend it. You can easily exceed the maximum torque, and do permanent damage."

What does a good torque wrench cost?

扭矩扳手的类型和尺寸范围很大,因此在定价方面很难应用一般规则。

You can get a perfectly good torque wrench for a bicycle for$ 25。您可以在周围获得家庭汽车维修的入门级型号$ 40,但是需要更精确的专业机械师或工程师很容易花费五倍。

我们的购买指南应帮助您缩小要求。掌握这些信息,您可以比较单个元素,直到您满足您的特定需求的最佳扭矩扳手。

扭矩扳手提示

  • 如果您正在从事一份复杂的工作,并且您担心在将它们拆开时会走向何处,请使用手机在“图片之前”和“”图片中拍摄。万博app在哪下载然后,您将获得方便的参考,以正确的顺序 - 是时候将所有内容放回原处时。

  • 除非专门制造商的指示,never grease or oil nuts and bolts before tightening. You may think lubrication will make them easier to undo next time, but it can stop them tightening properly. If the maker didn't do it, you shouldn't either.

  • 分三个阶段拧紧。首先,用手在螺母或螺栓上绕。他们不必紧绷,您只是把它们放在那里。
    其次,将扭矩扳手设置为建议的总数一半。如果您有一个以上的螺母或螺栓,则可能有制造商建议的固定顺序。遵循它很重要。
    第三,将扳手设置为最终扭矩量,然后再次按照序列进行操作。这样可以确保甚至准确的拧紧 - 在诸如缸盖之类的东西上尤其重要。

A torque wrench is a precision instrument. Dropping it can knock the accuracy way off. Recalibration services exist, but get a quote – a replacement may be cheaper.

FAQ

问:扭矩扳手是否需要特定的护理或维护?
A.
高质量的扭矩扳手是一种耐用的工具,应该提供多年的服务,但他们需要一些照顾。它因类型而异,因此始终仔细遵循制造商的说明。大多数是常识。注意使用时不要将其丢弃。保持卫生。在另一种情况下存储,因此其他工具不会损坏它。扭矩扳手应定期重新校准 - 建议定期使用的工具每年一次。同样,请遵循制造商的建议。

Q. Do I really need to use a torque wrench on lug nuts? In the auto shop, they just use an air gun?
A.
When manually tightening lug nuts, it's surprisingly easy to over do it. It's possible to strip or break wheel studs, and even warp brake rotors. Both are expensive to fix, and the latter has the potential to be extremely dangerous. Use of a torque wrench helps avoid such problems.

尽管他们确实在专业商店中使用了空中工具,而且没有什么比打破顽固的螺母的冲击扳手那样,该工具具有内置的离合器,可以在更换轮子时使用,以避免过度触及。

Q. How do I convert foot pounds (ft. lbs.) to Newton meters (Nm) and vice versa?
A.
1英尺磅等于1.3558牛顿仪表,因此,如果您想扭转它,牛顿仪表等于0.7376英尺磅。

You can do the math from there. Alternatively – and much more easily – you can either look up conversions on the internet (you can print out a chart and tape it to the garage wall), or get a conversion app for your smartphone!
