A single ring gear planetary transmission device having a small difference between the teeth of the meshing gears

摘要

A single ring gear planetary transmission apparatus having a small difference between teeth, comprising: at least one pinion shaft which only rotates only in the axial direction; At least one external gear provided at said low speed; Two high-speed shafts, each of which only rotates in an axial direction, and to which two eccentric sleeves are tightly mounted; One drive plate having two mounting holes fitted to rotate with the eccentric sleeve and a tooth slightly more than the teeth of the corresponding external gear for engagement with the slow axis; At least one balance plate for assuring smooth movement of the transmission, having two mounting holes and one or more shaft passing portions fitted to the high-speed shaft through an eccentric sleeve; Wherein the at least one low speed shaft passes through a driving hole of at least one drive plate and the external gear at a low speed shaft is positioned so as to engage with the ring gear of the driving hole to make a planetary transmission with little difference between the teeth.
