SCHMIDT

Couplings enable translation of shaft centers while rotating

When transmitting power between shafts with different centers, which have traditionally been constituted of a spline shaft and a universal joint, Schmidt couplings can be used to efficiently transmit power in a compact form factor. Schmidt couplings 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 displacement of the shaft center is determined by the length of the link, so not only is it possible to transmit power between different shaft centers, translation of shaft centers during rotation is possible as well.

NSS Models

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.

DL Models

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.
