Curved jaw shaft couplings from Techdrives are now available with 4 larger sizes. These couplings consist of two hubs and a central flexing element. The hubs havejaws with curved surfaces that mesh with the moulded curved surfaces of the polyurethane elements so that torque transmission is made with the polyurethane in compression. With steel, aluminium and cast iron hub options together with elements of varying stiffness, curved jaw couplings give machine designers freedom of choice. The Techdrives range of GR couplings has been expanded from shafts of 5 to 90mm up to 145mm with the addition of 4 new sizes, making 13 sizes in all. The simplicity of the design leads to highly economic selections.
A choice of three polyurethane grades for the central element allows a play-
The lowest cost hub options use a keyway connection to the hubs. Some designers prefer to avoid keyways because they are stress raisers, expensive to machine and they do not allow adjustment of timing. Here the GR curved jaw couplings have an answer with aluminium clamp hubs available for shafts 5 to 45mm. A single side-
Curved jaw shaft couplings from Techdrives are similar and largely interchangeable with our European models, but offer good availability, high quality and a long service life. More details are given on the Techdrives website www.techdrives.co.uk.
