DL Models - SCHMIDT - Miki Pulley Coupling - Miki Pulley Vietnam

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.Since power is transmitted by links, extremely little reaction force is generated, which allows a large eccentricity of up to ±4 mm.

NSS Models - SCHMIDT - Miki Pulley Coupling - Miki Pulley Vietnam

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.

*If the number of links is not 3 × 2, the part must be made to order.

*Max. rotation speed does not take into account dynamic balance.

*Select NSS model SCHMIDT couplings as guided by the design checklist on P.96-99, with due consideration to service life.
