FRICTION GEARING WITH FLEXIBLE COUPLING Russian patent published in 2004 - IPC

FIELD: mechanical engineering. SUBSTANCE: invention can be used in mobile and household appliances and processing equipment. Proposed friction gearing with flexible coupling contains planet pinion installed for rotation, two fixed wheels rigidly connected with gearing housing and installed coaxially to input shaft from opposite sides of plant pinion, flexible deformable rim with inner working surface interacting with planet pinion and fixed wheels through corresponding diametrically opposite sections, and rim deforming device. Working surface of said wheels, planet pinion and rim are provided with friction oxidoceramic coating, and two identical additional ring members are press-fitted from inner side of deformable rim, each being arranged between planet pinion and corresponding fixed wheel. EFFECT: increased service life of gearing. 4 cl, 1 dwg
