Flexible coupling: elastomer coupling Lovejoy

Lovejoy's S-Flex coupling design is simple, ensuring ease of assembly and reliable performance. No special tools are needed for installation or removal. S–Flex couplings can be used in a wide variety of applications.
Its design is comprised of three parts. Two flanges with internal teeth engage an elastomeric flexible sleeve with external teeth. Each flange is attached to the respective shaft of the driver and driven and torque is transmitted across the flanges through the sleeve. Misalignment and torsional shock loads are absorbed by shear deflection in the sleeve.

In all designs, pre-molded teeth along the diameter of the sleeve engage with teeth of the coupling flanges. No clamps or screws are needed to connect the flanges with the flexible sleeve which securely lock together under torque for smooth transmission of power. All three sleeve materials are highly elastic which permits the S–Flex coupling to protect connected equipment from harmful shock loading, vibration, and shaft misalignment.

The S–Flex coupling from Lovejoy offers combinations of flanges and sleeves which can be assembled to suit your specific application. Thirteen sizes are available with torque capabilities that range from 60 in-lb to 72,480 in-lb.
