Mechanism for converting rotary motion into linear reciprocating motion

摘要

A rotary to linear reciprocating motion converter includes an endless chain 5 coupled to spaced drive and driven sprockets 3, 4, an output rod 8 slidably disposed on a guide bar 6 via a slide member 7, and a connecting rod 16 coupled between a chain link and the upper end of the output rod by pivot pins 17, 18. Rotational moments about the guide bar are absorbed by a roller 11 journalled on a shaft 10 extending out from the slide member 7 being slidably disposed in a slot 13 in the sidewall of the mechanism housing.
