ECCENTRIC MECHANISM FOR CONVERTING ROTATIONAL MOVEMENT INTO RECIPROCAL MOVEMENT OR OSCILLATORY MOVEMENT Russian patent published in 2009 - IPC F16H21/16 F16C27/00 

FIELD: engineering industry.

SUBSTANCE: invention refers to engineering industry, and namely to mechanisms converting rotational movement into reciprocal or oscillatory movement. Eccentric mechanism for converting rotational movement into reciprocal or oscillatory movement consists of a support, drive shaft, piston-rod, driven link and eccentric bearing with rollers of various diameter. Outer race of the above bearing is rigidly attached to piston-rod, and inner race - to drive shaft. At that outer and inner races as well as rollers are equipped with engaged ring gears. Bearing inner race is fixed on drive shaft eccentrically, and transfer ratio i_"вп" from drive shaft to eccentric bearing roller system, or inverse ratio i_"пв"=1/i_"вп", is integral number. In addition to ring gears, rollers and races include cylindrical side races as well.

EFFECT: invention provides the possibility of modifying law of movement owing to harmonics summation, and reduction, i.e. reducing the number of double strokes of driven link in comparison to the number of drive shaft speed.
