MOTION TRANSMISSION DEVICE (VERSIONS) Russian patent published in 2001 - IPC

FIELD: mechanical engineering. SUBSTANCE: invention relates to devices which provide for normal operation of machines. Device has pair of flexible identical cylindrical rings 1, flexible curvilinear needles 2, rigid wheels 3 one of which is drive wheel, and flexible transmission member 4. Rings 1 are provided with circular recesses. Needles 2 are secured on wheels axisymmetrically. Flexible rings 1 are pressed to member 4 by shifting of axes of wheels 3 relative to each other so that circular recesses form through rectilinear channel in contact section of surfaces along axis of which flexible member 4 is mounted loosely. Device variant is proposed, and it contains single and paired rollers one of which is driving roller. EFFECT: reduced rate of destruction of flexible member surface layer. 10 cl, 3 dwg
