Power device having a planetary differential equation motion conversion mechanism

摘要

PROBLEM TO BE SOLVED: To provide a planetary differential type motion converting mechanism for restricting uneven wear and a breakdown in a screw formed in a planetary shaft and in a screw of a rotor engaged with the described screw due to application of a load in the axial direction to a sun shaft, and to provide a power plant with the same.;SOLUTION: In this planetary differential type motion converting mechanism 100, a pitch of a screw 11 formed in a rotor 10 is set larger than a pitch of a screw 31 formed in a planetary shaft 30 within a range wherein the screw 31 formed in the planetary shaft 30 and the screw 11 formed in the rotor 10 are engaged with each other.;COPYRIGHT: (C)2010,JPO&INPIT
