Abstract:
An apparatus for converting an input rotary motion of a given input frequency &OHgr; to compound eccentric rotary motion, said input rotary motion produced by a rotary motion machine (7), comprising:non-rotating gear means (203) for affixation via a fixed gear housing (202) and housing fixing means (205) to a non-rotating component of said rotary motion machine (7); drive shaft means 201) for connection to an input rotary motion component (102) of said rotary motion machine (7); eccentric motion generating means (206, 206â€², 206â€³, 207, 208, 209) for generating and adding said eccentric rotary motion to said input rotary motion, resulting in a compound motion; pass-through rotary motion component means (102â€²) for having said compound motion imparted thereto; and attachment means for attaching an operating attachment (101) to said pass-through rotary motion component means (102â€²); wherein: said drive shaft means (201) is connected with said eccentric motion generating means (206, 206â€², 206â€³, 207, 208, 209), and said eccentric motion generating means (206, 206â€², 206â€³, 207, 208, 209) engages said non-rotating gear means (203), such that said given input frequency &OHgr; applied to said drive shaft means (201) about a primary rotational centerline (106) thereof causes said pass-through rotary motion component means (102â€²) to rotate at the same said frequency &OHgr; about said primary rotational centerline (106), and also to rotate compounded with an eccentric motion frequency &ohgr; about at least one secondary rotational centerline (212).
