1531355 Gearing converting rotary motion to reciprocating motion EASOM ENG & MFG CORP 8 June 1976 [9 June 1975] 23669/76 Heading F2Q An epicycloidal motion generating mechanism comprises a primary rotating member 32 adapted to be rotated about a central axis 28 by an electric motor 14, planetary members 42 which mesh a fixed sun gear 24 being rotatably mounted in apertures 40 in member 32, and a member 56 which is rotatably mounted about axis 28 and is provided on its underside with a plurality of radial slots 60 which are engaged by rollers 54 carried at or adjacent the pitch lines of the planet members 42. The member 56 carries a planet gear 66 meshing a fixed sun 62 and another planet gear 70 to which a crank arm 82, carrying a coupling member 88, is attached. As the member 32 rotates at constant velocity, the coupling member 88 is moved along a straight line 92 passing through the central axis 28. |
