COUPLING Russian patent published in 2001 - IPC

FIELD: mechanical engineering. SUBSTANCE: invention relates to nonstandard equipment which can be used for setting into operation gear train mechanisms or coaxial coupling of rods, shafts and like members. Coupling has housing made in form of bushing with central hole, and seating fillet surfaces. Novelty is than housing is coupled with resilient member and bearing. Resilient member is arranged in groove of housing provided with trapezoidal projections. Outer diameter of housing serves for tight fitting of inner race of bearing furnished with cage with balls arranged in ring groove. Outer race of bearing is of L- section. End face flat of bearing outer race features tribotechnical properties required for transmission of rotation to mated friction surfaces and is designed for tangential loading from bearing outer race. Axial loading at press-fitting of bearing inner race on housing surface is 23520 N. EFFECT: provision of multipurposeness of coupling and enlarged capabilities. 2 dwg
