Abstract:
An apparatus for converting rotary motion at a given input frequency .OMEGA. about a primary rotational center line, to rotary motion of the same frequency .OMEGA. about said primary rotational center line compounded with eccentric rotary motion at an eccentric motion frequency .omega. about at least one secondary rotational centerline, comprising:non-rotating gear means affixed via a fixed gear housing and housing fixing means to a non-rotating component of a rotary motion machine;drive shaft means connected to an input rotary motion component of said rotary motion machine, passing through said fixed gear housing from an input region of said fixed gear housing to an output region of said fixed gear housing, and by virtue of said connection to said input rotary motion component, rotating at said input frequency .OMEGA. about said primary rotational center line;lateral driving connector means affixed to said drive shaft means proximate said output region of said fixed gear housing and thereby also rotating at said input frequency .OMEGA. about said primary rotational centerline;eccentric motion generating means passing through said lateral driving connector means and thereby orbiting at said input frequency .OMEGA. about said primary rotational centerline, and further engaging said non-rotating gear means and thereby causing said eccentric motion generating means and secondary drive shaft means, eccentric motion driving bar means and eccentric motion drive shaft means thereof to also rotate at said eccentric motion frequency .omega. about said at least one secondary rotational centerline; andpass-through rotary motion component means connected to said eccentric motion drive shaft means, imparting both the orbit of said eccentric motion drive shaft means at said input frequency .OMEGA. about said primary rotational centerline and the rotation of said eccentric motion drive shaft means at said eccentric motion frequency .omega. about said at least one secondary rotational centerline, to an operating attachment attached to said pass-through rotary motion component means wherein,said apparatus is a modular device separate and distinct from said rotary motion machine;said apparatus further comprises a conversion module receptacle of a form substantially equivalent to an attachment receptacle of said operating attachment;said housing fixing means is so-fixed to said non-rotating component of said rotary motion machine;said drive shaft means is affixed to said conversion module receptacle and is connected to said input rotary motion component of said rotary motion machine by mating said conversion module receptacle with said input rotary motion component in substantially the same manner that said attachment receptacle of said operating attachment is mated with said input rotary motion component when said modular device is not used;said pass-through rotary motion component means is of a form substantially equivalent to said input rotary motion component of said rotary motion machine; andsaid attachment receptacle of said operating attachment is mated with said pass-through rotary motion component means in substantially the same manner that said attachment receptacle is mated with said input rotary motion component when said modular device is not used.
