These are couplings with different shaft centers that use the crank motion of a link. Power input at one end disc is transmitted via a link and center disc to another end disc.The amount of eccentricity is determined by the length of the link. Power can be transmitted smoothly when shaft centers are different. And since power is transmitted by the crank motion of the link, translation of shaft centers during rotation is possible. The standard NSS model has 3 x 2 links, while quasi-standard NSS models increase the number of links and the rated torque. cp_ns_nss_s.jpg
The maximum size with disc spring couplings for high-output applications is an outer flange diameter of 262 mm and rated torque of 8000 N・m. Single-element types with high torsional stiffness and flexible double-element floating-shaft types that connect double elements with an intermediate floating shaft are available. The floating shaft is particularly able to handle the setting of lengths according to customer requirements.cp_sf_sfh_s.jpg
The three-layer construction of the metal coil spring component enables high torque transmission to be achieved in a compact form factor.A type that uses SUM24L-equivalent material as the hub material and piano wire for the coil spring (the MM-K type) and a type that uses stainless steel for the hub and coil spring to boost corrosion resistance (the MM-K-S type) are available. Select the type suited to your usage environment. cp_bu_mmm_s.jpg
