A major part of the torque is due to friction, so the differences in friction can cause large variations of the preload with the same torque setting; [3] angle-controlled tightening (also known as turn-of-the-nut method) is a technique where the bolt joint is rotated to some angle that ensures the stress beyond the yield limit of the parts ...
In physics and mechanics, torque is the rotational analogue of linear force. [1] It is also referred to as the moment of force (also abbreviated to moment).
Similarly, an inch-pound (or pound-inch) is the torque of one pound of force applied to one inch of distance from the pivot, and is equal to 1 ⁄ 12 lbf⋅ft (0.1129848 N⋅m). It is commonly used on torque wrenches and torque screwdrivers for setting specific fastener tension.
Torque multipliers only have a fraction of the final torque pressure on the drive tool making them a safer choice. Torque multipliers typically employ an epicyclic gear train having one or more stages. Each stage of gearing multiplies the torque applied. In epicyclic gear systems, torque is applied to the input gear or ‘sun’ gear. A number ...
A click torque wrench. A torque wrench is a tool used to apply a specific torque to a fastener such as a nut, bolt, or lag screw.It is usually in the form of a socket wrench with an indicating scale, or an internal mechanism which will indicate (as by 'clicking', a specific movement of the tool handle in relation to the tool head) when a specified (adjustable) torque value has been reached ...
Torque measurement is somewhat complicated since there are two machines in tandem - an inline torque transducer is the preferred method of torque measurement in this case. An eddy-current or waterbrake dynamometer, with electronic control combined with a variable frequency drive and AC induction motor, is a commonly used configuration of this type.
Torque charts are available to specify the required torque for a given fastener based on its property class (fineness of manufacture and fit) and grade (tensile strength). Spring Analogy for a Bolted Joint. When a fastener is tightened, a tension preload is develops in the bolt, while an equal compressive preload forms in the clamped parts.
Most torque screwdrivers allow the torque to be set to any value within a range. All have a torque-limiting clutch that disengages once the preset torque has been reached. Torque screwdrivers can exert torques from 0.04 N⋅m to at least 27 N⋅m. [1] Although no single tool covers the entire range, low-, mid-, and high-torque ranges are available.
