Custom multi-beam coupling developed for rocket launcherA combination of extreme heat, dust and combustion debris is not the best working environment for any coupling. But it proved ruinous for the initial brand that was specified for a position sensing system on a truck-mounted missile launcher. The viscous mass that these conditions created resulted in the coupling becoming completely solidified. Repeated failure of the brand was the outcome.
Because of these problems, Huco Dynatork was asked to propose a solution. The Hertford-based coupling specialist was ideally suited to the task for two reasons. Many of its products have a proven track-record for reliable operation in extremely aggressive environments. And as a manufacturer of the broadest variety of coupling types on the market, it was able to provide a custom-designed solution that was optimally suited to the needs of this defence application.
The result was a purpose-made coupling based on the Huco Dynatork standard 19mm diameter stainless steel Multi-Beam. This intrinsically balanced product has proved itself a highly cost-competitive method of accommodating any combination of axial motion and angular and parallel misalignment. Its compact one-piece construction has no wearing elements to compromise service life.
Huco Dynatork is readily able to manufacture non-standard products cost-efficiently. This ability enabled the company to economically produce a stretched version of its 6-beam Multi-Beam for the rocket launcher positioning system. As well as being nearly double the standard length, the Multi-Beam design was also modified to accept a specially moulded neoprene gaiter. This key element effectively shields the beam mechanism from debris attack. The adapted Multi-Beam proved to be the ideal solution and was swiftly retrofitted to a fleet of armoured launch vehicles.
