What is a pneumatic torque key?

Pneumatic torque key is a tool driven by air designed to apply a specific, pre -set torque or voltage to the fastening element, usually nuts and screw. This accurate tension is important in many more fast applications where it is necessary to maintain very close tolerances. Unlike other forms of torque keys, many pneumatic rotating keys offer a wide range of torque settings. They are also generally smaller, more powerful and cheaper to run than electric or manual versions. This shaft is equipped with an adjustable clutch that is designed to "slip" or relaxed at a pre -set voltage. The end of the pneumatic rotary key shaft is equipped with mounting that allows you to connect different tools to the torque key depending on the application. When the pneumatic rotating key is applied to the mattress, the bolt assembly, the torque tool or the matrix tightening until the predetermined voltage is reached, whereupon the clutchAnd it will release and the key will no longer apply the voltage to the matrix.

Many engineering applications require that the fasteners be filled to a specific torque setting. This is especially true for applications where several fasteners are used to secure two components together. For example, the cylinder of the car engine is usually attached six to eight assemblies. As the cylinder head relies on the perfect adaptation between its lower surface and the engine block to ensure an effective sealing seal and correct alignment of the peripheral drive mechanisms, these pins must be tightened to exactly the same level. This accurate tension is achieved by the torque key.

For various reasons, the use of compressed air to control pneumatic horrible wrench is a common practice in industries where these tools are often used. The pneumatic torque key is smaller and more mastered thanElectrically controlled model of similar capacity. For this reason, the air -controlled tools are much stronger in the packages reasonably size than their electric counterparts, such as the torque key. Pneumatic torque keys are also cost -effective. This is because the formation of a source of compressed air is cheaper than the use of electrical tools. Due -driven or manual rotating keys are often equipped with a limited number of voltage settings.
