Coupling technology to replace industrial universal joint, jaw couplings and beam coupling

Small couplings have usually been those of the industrial couplings (beam, bellows, elastomeric / jaw type coupling).
For their needs, high speed low angles of misalignment these couplings offer performance over that of the universal joint, who needs to be maintained, have a limit of how fast they can run and the 3 piece design (propeller joint and 2 yokes).
Lovejoy couplings are probably the most well known but the technology for jaw couplings is identical regardless of manufacturer. 3 pieces, a input hub or yoke, an output and a spider or urethane insert is the most common configuration. Lovejoy also make universal joints at the smaller end like their D-4 and D-6 uni joints. Smaller block and pin design universal joints as well as the needle bearing NB range also are available in the sub 3600 inch lbs range. The block and pin is only rated to 1750 RPM where the NB range can run up to 6000 RPM.
Regardless of configuration there is still 3 components in each of these jaw or uni joint couplings, where with Twin Spring Coupling we design our coupling to be a 1 piece design with no wear parts like spiders or universal joint crosses that need to be maintained.
So this has meant these industrial couplings allow only a few degree of misalignment which means anything over 4° leads to premature failure of these couplings.
We at Twin Spring Coupling offer something different, a high speed, high rigidity coupling that is flexible to over 10°. This allows design engineers to redesign their equipment without the worry of these premature failures and in today’s 24/7 systems that require as little downtime as possible this comes as a welcome change to be able to get the most out of their designs without downtime and lost productivity.
