Shaft couplings, collars and universal joints in new catalogueTechdrives is offering a new 44-page catalogue with 14 different types of flexible shaft couplings plus shaft collars and universal joints. It is freely available to download (2MB PDF, bookmarked for easy navigation) or as a paper version on request. Coupling bores range from 3-150mm, generally for keyway connection but backlash-free clamp hub connections are also offered in many cases. Rated torques start at 0.4Nm for the smallest couplings and extend to 23,000Nm for the largest.

The Techdrives range includes three-piece jaw couplings and Oldham couplings that are torsionally soft; these are suitable for simple machinery where accurate synchronisation is not needed, and have the advantage of dampening vibrations. There are three types of one-piece all-metal couplings - beam, bellows and spring types - to give a choice of stiffness, and the one-piece design means that they are backlash-free. Finally, metal disc couplings give high stiffness with backlash-free designs, suiting high speeds and precise transmission of motion. In addition, the torsionally soft and metal disc couplings can be supplied as spacer couplings in customised lengths of up to 6m.

As well as shaft couplings the new catalogue includes universal joints and shaft collars. The universal joints are designed for machine applications with bores of 6-50mm and they are available with single, double and telescopic designs. Shaft collars are offered in steel or stainless steel, and as a one-piece clamp collar or a two-piece split collar. In both designs careful attention is paid to the machining to ensure squareness of the faces to the bore.

The new catalogue gives dimensional and performance data, as well as part numbers. There is also a selection guide with drive formulae and a tabular overview or the range to make choosing the right coupling easy.
