Schmidt coupling

The Schmidt coupling , named after its inventor Richard Schmidt, is mostly used in roller drives with large offsets, ie when, for example, the thickness of the materials used varies or when the rollers are ventilated. One of the main tasks of rollers is that they can be adjusted radially and still have to be driven. The Schmidt coupling system is based on a parallel crank gear . When a disc rotates , the rotational movement is transmitted by three or more links during the rotation by the build-up of alternating tensile and compressive forces in an absolutely uniform and thus angular manner on the next disc. I.e. If the offset changes under load and during operation, the system adjusts itself via the compensating element in the middle disk without any external reaction. Radial vibrations are not transmitted from one shaft to the other. The advantage of roller drives is that this coupling system is able to compensate for large radial misalignments in a short and angular manner.
