Exploiting the wedge theory can be very useful. One does this to produce a sturdy self-locking configuration, and this is the function of HL or hard lock nuts. A sliver driven into the break between a drum and the cylinder that encircles it generates a structure that fastens forcefully. When this result is accomplished by corresponding furrows in the nuts and bolts, it is possible for a wedge to be hammered into place but this leaves the arrangement hard to handle.
Rather than using the brute force of a hammer, it is preferable from an operability standpoint to use one convex and one concave nut in place of the wedge and hammer. Tightening these two produces the same effect as driving a wedge in with a hammer. Using a threaded screw makes it easier to properly and securely position the wedge.
Self-locking ones work in pairs. The bottom nut is tightened first, followed by the upper one. Installing the top nut by hand creates a tightening margin. The intrinsic self-locking outcome is brought into play by the torque created when using a wrench to turn the top nut.
The evolution of this brand of nut had the intention of ending the nuisance of damaged bolts and slack screws. This style of formation has the benefit of averting any shortfall in axial force ensuing as a result of metal fatigue. Traditional Japanese architecture motivated the fabrication of a wedge-shaped, double nut assembly to economically eliminate the drawback of slackness in screws as well as creating enhanced workability.
Safety and reassurance are provided by the fact that these never work themselves loose. Many tests of screw looseness have attested to the excellence of this type of nut in preserving the initial tightening strength. On site evaluations by those in the construction trades have confirmed that the substitution of these innovative units in place of old-fashioned methods significantly reduces costs in terms of man-hours. Another huge advantage is that the security of these locking units prevents construction companies from facing litigation arising from accidents as a consequence of screws coming loose or bolts shearing off.
There are several situations in which only this equipment has been demonstrated to be satisfactory. One such situation is where a recurring external power is exerted in the identical rotational route as the bolt, or upright pertinent to the bolts, or perpendicularly in relation to bolts. Another instance can be when vibrations are continuously present. Severe vacillations in temperature will also be contended with by using these mechanisms.
HL units construct a seal equivalent to adhesive bonding, riveting or welding. In contrast to these fixings, an HL nut can be simply removed for examination or repairs. HL units are capable of being re-used over and again because their self-tightening performance will not depreciate over time.
Hardlock Industry Co., Ltd. Is the foremost manufacturer of these very useful fasteners worldwide. Their technology has been approved for aerospace applications by projects including the Kansai International Airport. Leading American aerospace companies including Boeing utilize HL nuts for their safety record. The Japanese Olympic bobsleigh employs special HL units made from lightweight titanium, which have a whole bag of benefits all their own.
