Yielding couplings, i.e. with means permitting movement between the connected parts during the drive > Universal joints in which flexibility is produced by means of pivots or sliding or rolling connecting parts > one coupling part entering a sleeve of the other coupling part and connected thereto by sliding or rolling members > the rolling members being balls, rollers, or the like, guided in grooves or sockets in both coupling parts

Yielding couplings, i.e. with means permitting movement between the connected parts during the drive (couplings disconnectable simply by axial movement F16D1/10; slip couplings F16D7/00) > Universal joints in which flexibility is produced by means of pivots or sliding or rolling connecting parts > one coupling part entering a sleeve of the other coupling part and connected thereto by sliding or rolling members (F16D3/18, F16D3/24 take precedence) > the rolling members being balls, rollers, or the like, guided in grooves or sockets in both coupling parts
