Zero-Backlash Jaw Couplings for Motors

Ruland zero-backlash jaw couplings have high dampening capabilities and can accommodate all forms of misalignment, making them well suited for applications with high acceleration and deceleration curves that couple a motor with a screw driven actuator or gearbox. Ruland jaw couplings are made up of two aluminum hubs and an elastomeric insert called the spider. They give motor manufacturers and integrators a standard coupling with a high level of customization. Hubs can be easily interchanged between clamp and set screw, with or without keyway and spiders have three durometers to choose from. This flexibility allows designers to specify an outer diameter with a variety of inch and metric bore sizes will match joined components such as lead screws, ball screws, and gearboxes.

Ruland hubs are manufactured with a proprietary curved jaw profile that ensures zero-backlash operation for fine positioning. Designers can select from three different spider durometers, enabling them to balance dampening, torque, and torsional rigidity based on the needs of their application. The spider serves as an inexpensive wear element that restores the coupling’s performance characteristics when replaced, saving maintenance costs when compared to couplings that must be entirely replaced. In the event of failure, the hub tenons will interlock for continued power transmission to allow the system to be shut down safely.

Zero-backlash jaw couplings are manufactured by Ruland with bores sizes ranging 1/8” to 1-1/4” and 3mm to 32mm.
