Abstract
There is disclosed a transmission between an orbiting element and an element rotating on its own centers. It is disclosed particularly in connection with a motor operating on the Moineau principle and the invention replaces the conventional connecting rod with double universal joints and it also can modify the ball and tube arrangement disclosed in earlier patents.
Claims3
A transmission construction for transmitting power between the rotating and eccentrically gyrating inner member of a Moineau type motor, and a shaft running on true centers and driven thereby, comprising an extension on one end of said inner member disposed on its lathe axis, and a recess associated with said driven shaft, said extension entering said recess, whereby transmission of torque between said inner member and said shaft is achieved solely by the eccentric gyration of said inner member acting against said recess, a ball-and-box support for the opposite end of said inner member, said support comprising a head threadedly mounted on the said opposite end of said inner member on the center of the cross-section of said opposite end, but eccentrically of said head, said head carrying a ball on its axial center, and means for orienting said ball so that its center is on the lathe center of said inner member.
